Do you think the philips flash 28 BCS will work on my canon EOS 10D? Do you think it will give an error?

Im looking forward to your reply

HI
I use the Vivitar Auto Thyristor 2800 on my digital canon 20d. and it works just fine. But it is not attached to the hotshoe. I took it apart and build in a jack sleeve. So i can use it with the flash sleeve. I think you might be interested.

Measured voltage at the connection points of the suntax 9000ETS was 3.5 volts DC and therefore suitable for the Canon EOS 10D, I had to switch the wiring because the positive was connected to the the side instead to the central pin, which gave an error at the display of the camera.
The suntax 9800A measured 68 Volts DC and the Achiever 115M was good for 64 volts DC.

Hi

A friend of mine sold me his Old Vivitar 285,for use on my Fuji S700o. Following your instruction on how to measure, I found it to be 6 to 8 volts. Vivitar reports the older models, those made in japan have a trigger voltage of over 300. WHich is correct??

I have read of many bad reports on a safe sync product. So I decided too have a go and make my own. I have made three versions of this, but they all do the same job. Letting the camera only see 3 or 5 volts, no matter what the strobe trigger volts are. I then extended the idea too have a slave flash to fit on top of the camera giving a single flash for use with studio flash`s. No more preflash woes.

I am going to set up a studio in my home in 6 months. After reading the article"What Canon Didn't tell you about Powershot Flash Photography", realized I had a problem in flash sync. between Canon Elan TTL and my new Canon G6 E-TTL. I may need three or four slave units if I light the white back drop. How do I connect my G6 hot shoe to my studio strobe and other non-digital flashes? I have 1.Briteck HS 1000 Professional studio flash with PC and slave trigger;2. Canon Elan Camera (prefer to use my G6 most of the time); 3.Canon 430 EZ flash; 4. Vivitar 730 AF C(Canon dedicated); 5. Vivitar 2500 auto flash w/PC & hot shoe (center post); 6. Vivitar 252 flash w/PC & hoe shoe. All these are non-digital. Digital I have my Canon G6 and Canon 420 EX E-TTL. I have one slave with a PC outlet and one just a hot shoe (center post).

Will the studio flash and the other 5 flashes be tripped by the pre-flash on the G6 built in flash, Canon 420 EX, or any wireless unit I might hook up to the G6? Can anyone help me?

I have Canon PowerShor A200.

Looks like I have got the dreaded E25 error.

i.e. When I open the lens door, I get a motor noise. Sounds like the camera is trying to focus. Then the noise stops and E25 is displayed on the LCD.

I can access the memory via USB connection but cannot take pictures.

Does any one have a solution?

Thanks

After reading through the info about flash voltage, I checked the manual on my Nikon D70. The quote listed on this site is, verbatim, the wording in the D70 manual. The flash trigger can handle up to 250 volts.

In addition, I checked the voltage across the hot shoes of my two flash units. My Sunpak Auto 411 measured at 75 volts, and my Vivitar Auto 225 (not yet listed on this site) also measured at 75 volts.

Keep up the great work. This site has been a tremendous resource.

Mr. Kevin Bjorke

Looking for information about to use a flash Metz 32CT-3 in my Olympus C-7070 I find your web site that alert me of the dangerous voltage of old strobes. (First at all , thank you for this.)
Well, I contact Metz in Germany and they say me "flash units of type Metz 32 CT-3 are already loaded with a
so called low voltage trigger circuit according the international standard called ISO10330 1992-11 allowing trigger voltages from 3.5 to 24 volts. A 32 CT-3 provided only 21V (measured unloaded) to the camera which should be suitable for all digital cameras as a Oly C7070 as well."
I contact Olympus but they never contact me.

In your site I read this "Marco Fortin-Metzgen checked with Olympus Europe on his C4040 — that digicam has a trigger voltage of 10V, so Olympus too recommends strobe triggering in the 3V to 6V range".
So, ¿Who is right? and ¿what is "Iffy" in your voltage table? -


Obviously, I' don't want to damage my camera!!
If you can help me I be very grateful.

sincerely,

From http://www.metz.de/en/photo_electronics/faq/19/148/show.html

Metz mecablitz 45-CT 1 units featuring a model number that is smaller than 534 000 are fitted with a so-called high-voltage ignition circuit. These flash units must not be directly connected to modern cameras as this could even damage the camera!

All other flash units of the Metz mecablitz 45 CT and 45 CL series feature a low-voltage ignition circuit in keeping with the current standard.

I just bought a pair of Norman 400B battery-powered flash units. Neither of them would fire using my Pocket Wizard radio triggers, nor would they fire with any optical slave in my studio. They fired just fine hooked directly to an EOS-1 film camera. (I'm not stupid enough to hook this thing directly to a digital camera for testing.)

When I called Norman tech support, they told me that they had lowered the trigger voltage on the 400B to 5 volts, because they were getting complaints that the strobes were frying shutters on new digital cameras. So now the strobes won't 'see' the radio or optical slaves. I had to pay shipping for my brand new units back to Norman so they could raise the trigger voltage to 12 v.

<rant>
This is idiotic. Nowhere does Norman say they have done this -- B+H still sells the Wein optical slave on the Norman 400B page. I wonder really how many of their customers still use these packs on a flash bracket for 400w/s wedding photography? I suspect that the vast majority of photographers who buy Norman are using these as location lighting systems, using radio and optical slaves.

The solution for Norman is to put a decal on the unit advising photographers to use a Wein Safe Sync for direct camera connection to the pack. That's what I have to do for every other big flash unit, anyway, if I'm not using the Pocket Wizards.

"tap the padded usb cover part on a desk",

even though it do sound a bit 'caveman way' of solving a problem ...
however I am out of patience.

It do sound like it is some sort of problem with focussing, because the camera work when the lens is closed but as soon as you open the lens it make this awfull noise & display the dreaded E25

Trigger voltages checked:-

Sunpak SP40 = 47v

Srarblitz 200M = 259v !!Beware!!

Miranda 700 CD = -7.98v

Incablitz 328AZ is a recommended alternative flash for Panasonic FZ20,
Note some say Incablitz 280NZ is fine. I have used it OK, but with a reported firing voltage of 78v, I will not continue.

Great site, info otherwise difficult to obtain.

WHY DON'T DIGITAL CAMERAS ISSUE WARNING RE COMPLIANCE WITH ISO 10330, OR BETTER STILL....DEVELOP A DIFFERENT ATTACHMENT FOR THAT STANDARD?

Minsik says,

My Sunpak Autozoom 4000 hammerhead flash could not be used with the canon G2 (would have looked spectacular!), but after reading the information below i was willing to give it a new chance with the Rebel XT. It really does works great with the digital rebel xt.


Just take a multimeter and measure the open cct trigger connector, if less than 250v @ fully charged with a new battery set, (after charging several minutes) then you are ok.
I use my sunpak autozoom 4000 on automode, it has a hotshoe sensor, and so i set the rebel xt to manual mode 1/200th sec and f stop as set on the flash sensor. I can dial different apertures on the sensor and just set the manual to that setting. Flash now has lots of power and seems ok even at 18mm wide. Exposure seems spot on too.

---------------------------------------------------------snip---
Chuck Westfall, Director/Media & Customer Relationship, Canon USA, advises as follows regarding the flash sync circuit of the EOS Digital Rebel XT (EOS 350D):

*****
The EOS Digital Rebel XT uses a modified version of the EOS 20D's shutter unit. Consequently, acceptable trigger circuit voltage for both cameras is the same, i.e., 250 volts. Except for the original Digital Rebel, all current EOS digital SLRs (i.e., EOS-1Ds Mark II, EOS-1D Mark II, EOS 20D and EOS Digital Rebel XT) generate their X-sync signals electronically rather than mechanically. This is why they have higher acceptable trigger circuit voltage ratings than earlier models like the D30, D60, 10D and original Digital Rebel. These older models cannot be modified to achieve a higher trigger circuit voltage rating, since such a modification would require a different shutter mechanism as well as a complete redesign of the supporting circuitry.

Doug

I reported a while ago that the Sunpak autozoom 4000 hammer head flash triggering at 200v. Yes thats still right, but now i have a Canon Rebel xt and have verified that the electronic shutter in that is ok up to 250v. So the Sunpack lives again! Yes it works 100% and a new set of rechargables and its usefull again.
Actually i didnt want to buy c cells so got an old Sony SX ENG camera battery that was on its last legs and split that apart. Inside are 10 c (sort of, right ehight @ 50mm but that the diameter is a little smaller instead of 26mm its only 22mm. anyway these "old cells have lots of grunt and have saved me the expense of new cells.

Check you local tv station foe some of these old packs perhaps.

Hi!

I just found an older strobe:

AGFATRONIC 301CB

I tested it with a Nikon D70, but I forget to remember the voltage problem. *eek*
This Strobe has a voltage of:

240V (+ at middle pin)

So it shouldn't be used with modern cameras. In fact, it didn't kill my D70 *huh*

Does it work when you trigger it with the test button?

If not, make sure you have the batteries oriented correctly (the holder is usually marked for which way they go) -- if this is OK, clean the contacts.

If that doesn't work, try another set of batteries.

Sunpak 2800BZ -- triggers at 6.8V -- centre positive.

Vivitar 2800D -- triggers at 8.9V -- centre positive. (note the "D" is important -- Vivitar 2800 models without the "D" cithout the "D" can be high voltage -- 130V +!)

All three work fine from Panasonic Lumix FZ20 digital and Nikon F401 SLR.

Looking through the posts for flash voltages I have to ask is the synch voltage generated by the flash and the camera is just acting as a switch closing the contacts and firing the flash. Why I ask is I was trying to test a wireless flash trigger and if a multimeter is placed over the output plug a cicuit should be made when the test botton is pressed. I do not seem to be able to measure any such circuit making could this be that the circuit closure is too brief to measure or am I down the wrong path.

I was trying to test this to operate another circuit remotely but have so far failed to get any output. The trigger definatly is workig as it fires the studio falsh lights no problem.

I've recently bought a digital multimeter. I set the FUNCTION switch to DCV "200" position and then connected the test leads to the "positive" and "negative" of the hotshoe. The reading was "12.0". So does it mean that the trigger voltage of my old strobe (National PE-357S) is 12V?

Hi all,

I took about 50 flash photos with a Sunpak auto124 on my Olympus C-8080...
Then I read that it is not a good idea :-)
Well it survived so far. But I will stop and wait until I have full confidence that I am not shortening the live of my camera before I use it again. I measure 180Vdc from my Sunpak auto124 but that is with a 2/3 used set of rechargeable.

I have sent a question to Olympus Australia about the max tolerated trigger voltage for the C-8080.
I will post the response as soon as I have one.

Here are my measurements. They were obtained by using a digital
multimeter to measure the voltage between the strobe's two
primary contacts (i.e. center pin and rail) on fully charged
units. I've also added the year I bought the strobe (all
bought new, so it is probably near to year it was manufactured):

Just tested my Achiever 115A/S Auto and slave flash voltage!
Test procedure:
1. I used a digital multimeter to test this flash. Both Positive and Negative probe is clamped to the trigger pin.
2. The voltage is recorded down before I press the trigger the test button on the flash.
3. Then the test trigger is activated and the voltage on the multimeter is recorded.
4. Another test is after I trigger the test button, wait a while for the voltage reading to a saturate value.
Here's my result:
1. 3.54V - Before trigger the test button on the flash
2. 3.82V - reading right after the test button is triggered.
3. 3.53V, 3.52V, 3.54V, 3.54V, 3.51V - saturated reading of the flash after the test button is triggered! (I tested for 5 times!
4. Average value of the trigger voltage: 3.52V
5. The maximum voltage recorded after the test button is triggered: 3.91V

Hope this help

In late October 2003 I posted info about my old Sunpak strobe but didn't realize until just now that I made a typo in the model number! Someone from Finland wrote to me to ask if I really meant "Sunpak Auto 26SR", not "Sunpak Auto 266SR". I checked my strobe & he's correct, it's a 26SR NOT A 266SR.

This is my old message with the INCORRECT MODEL NAME 266SR:

im Gegesatz zum 45 CT-1 hat der 32 CT-7, der wesentlich später auf den Markt kam zu einem Zeitpunt wo sich die immer noch gültige Norm ISO10330 1992-11 bereits durchgesetzt hatte, generell einem Niedervolt-Zündkreis, bei dem eine Beschädigung der Kamera ausgeschlossen ist. Die Zündspannung des 32 CT-7 beträgt 10V und ist daher auch für die 300D verträglich.

I have three flashes that I have checked the trigger voltage on with a digital voltmeter.
1.) Vivitar 283~serial No. K176509
108.6 volts
2.) Canon 277T
3.68 volts
3.) Sunpak Auto Zoom 1000 Canon Dedicated~serial No. 84004734
3.82 volts

I have used both the Canon and Sunpak flashes on my Canon 20D in manual mode. The Canon does a great job. I can not get as good results with the Sunpak, but I do not have a manual for it so I am not sure how to set it up.

I will not use the Vivitar on my Canon 20D with out getting a Wein Safe-Sync.

Hello, I own a Minolta X700 that works fine. I just purchased a Vivitar zoom thyristor 5200 flash unit for the camera. I saw the same flash on Ebay being sold with an X700 and figured they would work well together. When I attach the flash to the camera, all I get as a meter reading from the camera is a "flashing" reading of "60" for my shutter speed. No matter what I have the flash set to (Auto, M/TTL, 1/2, 1/4, 1/16)ISO, F-stop or shutter speed for either flash or camera, I still get the same reading from my camera. Did I buy the wrong flash? Do I need a synch chord? Or COULD something be wrong with the camera? I also tried a Sakar 27M flash unit which had no effect at all with the reading, with or without a synch chord.
Can someone please tell me what I'm doing wrong!

I just bought a new digital camera (Panasonic DMC-FZ20) and had intentions of using an old strobe flash that I've had for years on it until I discovered this great flap about strobe flash trigger voltages and digital cameras. To Panasonic's credit, the camera manual for the FZ20 states that "external flash units used (other than Panasonic's) should be designed for use on a digital camera and have a trigger voltage compliant with ISO 10330 (less than 24 volts)." But, it also says, "Some commercial flashes have synchro terminals with high-voltage or reversed polarity and use of such flashes may cause a malfunction or the camera may not operate normally." From what I've seen on the internet, this should probably be a much stronger warning.

Anyhow, here is my "for what it's worth" entry to this forum.

The old strobe mentioned above is a Vivitar 285 (made in Japan - SN 6834101) purchased in August 1981 at a U.S. Air Force exchange in England. It's been years since the last time it was used. But it still appears to be operational, that is, it charges up and recharges in the stated time interval and fires OK, off the camera.... but I haven't actually tried it taking photos. Now, how about this... with a fresh set of alkaline batteries installed, and after "re-forming" the capacitor in accordance with the manual, I measured the trigger voltage at least a half dozen times, on both the strobe shoe as well as the contacts of a PC cord. I consistently read 3.5, repeat, 3.5 volts; Not what I expected. Since this is the lowest reading I've seen reported anywhere for this model and have no way of knowing whether it's valid or not, I'm speculating that the unit may be defective owing to long periods of inactivity. Even though it's still like new (never really got a lot of use) and appears to be operational, albeit the low trigger voltage, I'm not willing to risk damaging a brand new $500 camera.

My question is, can I non ex flashes, such as canon's 540ez or Sunpak's PZ-5000 I know that I cannot use the E-TTL. What I am interested is will those flash perform the following :

1. Will power-zooming still functioning?
2. Will the flash emit focus-assist beam in the dark?

If you have tried them on your G3 or G5. Please let me know. Thanks.

Well, yesterday I measured the voltage with two different Digital Voltmeters (one is Wavetek, other was a cheap brand) and measured the same voltage: 4.55 VDC. I am an electrical engineer - you can be sure that I measured correctly.
With this information I have begun to use with the 300d - and so far the results are very good!

I got 10.8 volts to the center pin, and 6.2 volts to the second pin. I presume the second pin served some "dedicated" function for the Ricoh, but not sure what. You may include that in the excellent summary page.

I guess this puts it squarely in the "my call" category for use on my Digital Rebel. I am loathe to buy the Wien adapter, since it is about $50, and for a bit more than that I can buy a *dedicated* flash in the used market. Has anyone in this board used flashes with around 11 Volts on a Rebel or 300D camera? Any practical experiences to share?

Superb site, thank you so much, I've learnt a lot in the past couple of hours!
A number of off-site links are 404'ing, I know that's not your fault, but
it would be so nice if the new locations could be found in at least some

With reference to using an external flash on the Canon Powershot G5 - I have devised another method to use my old and powerfull BRAUN 370 BVC flash.

1) I have modified the foot of a flash adapter by shortening one side, so it does not activate the little switch on the camera, the camera now does not know that an external flash unit is connected.

2) I set the internal flash of the camera to reduced power, say by two 2 stops. I do not bother about the stop setting of the lens. I use P-mode.

3) I set the external flash to automatic, it will sense the light reflected by the scene and adapt its power accordingly.

4) I do trials and change the settings untill I have the desired result.

5) Especially in portrait photography I like to have sparkling reflections in the eyes of the model, caused by the internal flash of the camera; while the external flash bounces of the ceiling or of a white wall for general lighting of the scene.

Being able to use the digital camera for evaluation of the light distribution and as exposure meter is a real blessing.

Just measured a Vivitar 352 Auto Thyristor Flash with my Radio Shack Multitester (20,000 Ohms per volt) It spiked to about 190 volts, then dropped down to about 150 volts. So it's a definite No-No for digital cameras. Sorry I can't be any more precise, but the multimeter is analog. Mike

I own a Yashica(Kyocera) CS-220-Auto flash unit - anno 1990.
I measured 10.26 Volts between the centerpin(+) and the outside railcontact(-)
with an APPA-95 multimeter from Advanced Instrument Technology.

Tip for the electronic handyman ...
To use this old flash as an external slave flash, I connected a BPX43 (or equiv.) phototransistor
with its Collector on the centerpin(+, and his Emmitter to the outside railcontact(-).
The Base connection is not used and cutted off ...
The slave flash fires from a distance of ca. 10 feets or 3 meter.

I tested the trigger voltage on my Hanimex TZ2500 flash unit and got different results to that posted on your list.

I got 245V (versus the 196V Alaistair got). I was using fresh Lithium photo batteries which may explain the higher voltage. Tested using a Radioshack DVM (Last calibration on 8/29/2003 - was within manufacturers 7V tolerance, it read 3.8V shy of the 350V test voltage).

My digicam (Kodak DX6490) is rated up to 500V for an external flash unit. Sounds impressive and safe but a Kodak technical paper does recommend using a voltage regulator to 'protect the cameras circuitry'.
See http://www.kodak.com/global/en/service/publications/tib4378.jhtml

Wonder why they rate it at 500V then tell you to use a regulator? Wonder if it's safe to use the Hanimex unregulated or not? Hmmm....

I have an ancient external flash. It says Londa (has anyone heard about this again?) and the model is RX203.
I measured the voltage with an electronic multimeter and it says 203V (does it have any connection with the model name RX203?).
Then I decided to test it with my new Olympus C5060. I checked first on Olympus Yahoo forums FAQ and it is reported that the three Olympus (5050, 5060 and 8080) can tolerate up to 300V. So it should be ok. And it was! I pushed the shutter button, not without fear I must say, but everything went ok at the end!

I talked to Vivitar the other day, and they reported that the older 285 series of flashes have a synch voltage of 9v if made in Japan, and 300v is made in China. I tested the synch voltage of the one I have from Japan with a voltimeter, and it reports 8.7v, which is consistent with what they told me.

I also e-maild to olympus tech-service about trigger voltage for the olympus C 5060, here`s their reply:

"Dear Christoph,

We value you as an Olympus customer and appreciate the opportunity to assist you with this situation.

The flash may or may not work. You may try it, and since the camera has a built in voltage regulator there should be no adverse effects if it does not work."

So I don`t really know, but maybe they changed something (voltage regulator!?)in the newer range of digi cams.

Trigger voltage for Metz 32 CS-2 measured 4.68 volts.

I asked Olympus tech support about the trigger voltage for the C-8080. This is their reply:

Dear Mr. Shima:

There is no trigger voltage from the camera ; it is whatever is generated
by your flash... The concern is the "Back EMF" generated in that circuit
after the flash has fired. The firing circuit is protected by reverse
polarity so that the Back EMF is not a problem either..

Tested Sunpak Auto 433 D with volt meter. +6.75 volts at hot shoe contacts. Sunpak tech advised me the extra .75 volts will not damage my Canon A-1 or AE-1Prog.Also when testing pc connections. Take a 3/4 inch piece of heat shrink tubing and slip it over your probe tip.Leave enough off the probe tip so you can make contact with center part of pc connection.This will stop the probe tip from slipping off and causeing a short to the neg part of the pc connecton.It also works with hot shoe contacts.

I feel that I am not able to zoom in the same way like a Nikon 3.00 mp with 3x optical zoom!!! eg. when trying to zoom at a grduation or closer objects within a couple feet, does not maintain the focus but keeps zooming in and out of focus!!!

Any suggesions Will be greatly appreciated!

Glad I found this site before buying a flash for my new Canon G5. Thanks for keeping me from frying things before the warranty even expired by hooking up an old Vivitar 283 to the hotshoe.

Just got a Phoenix slave flash with the hopes of being able to use it with both digital and older 35mm cameras. From your site I was left with the impression that Canon Powershot models all used a pre-flash for the built-in flash. The Phoenix D91 BZS is adjustable for both single and double flash systems. This is a good thing because my G5 seems to operate with a pre-flash when set to "auto" mode but only fires a single flash in "program", "AV", "TV" or "manual" modes as best as I can determine. Even my older Powershot A20 acts similarly: pre-flash in "auto" mode and single flash in "manual" mode. Is this in fact a commom trait with other models as well?

I was so gobsmacked I forgot to ask if this was because the camera has a built in safety device.
Does anybody else have any info on this camera?

OK I just picked up an Ascorlight Q4 setup with 2 heads. Very nice! I had to fix it, though. When you tried to trigger the strobes it would just make a clicking sound and nothing would happen. So I started tracing through the circuit and found that one of the capacitors was not charging. So I kept looking around and located a 40A triac that looked like it wasn't functioning. So I jumped the gate pin to one side and wala the charge light came on and it worked! So traced backwards and found an optocoupled phototransistor was bad. I couldn't see the number on top because it had worn away. So I went into my parts collection and picked up the first optocoupler that I found and figured what the heck I can't lose anything. Good news is that it worked first time! I also measured the trigger voltage for this reference page. 30V. Good thing I read this page, I would never have known about Canon's low voltage requirement. I am going to go ahead and build the isolator circuit listed on here as that should just take a few minutes and I have all the parts. Hmm if there are other people interested in this circuit I could build them for rather cheap.

I finally measured my own Sunpak auto22SR trigger voltage and happily put my old, relatively cheap flash on my G3 hotshoe after having a desperate search through the net & e-mail asking to sunpak japan (but got no reply)

Though not using digital voltmeter (i'm using Sanwa analog multitester), i can assure that this measurement is accurate enough. Using the method described in this website too, i got only a small 1.3v - 1.5v from the hotshoe using fresh NiMH batteries. I haven't measured the pc sync .. sorry :)

Using it with G3 or maybe another powershot series, i'm using manual mode on the camera... for normal "in the room" shooting without flash bounce, i found 1/60 shutter speed or above and f5.6 is the average/best setting (based on histogram reading).. note: ND filter off, flash white balance...
this may be vary depends on room/light. taste etc.. still experimenting

I was afraid of putting a big Voltage and damaging the Camera, so I measured directly the Voltage from the Flash contacts, and it gave ~3.5V, i.e. under the 6V barrier for the 300D.

I too am disillusioned with Canon - your comment (aprox) "it's a consumer camera so we don't care if it works or not" hit it on the nose. - I expect to switch to Minolta if their DLSR with inbody stabilization really works - this fall. I have a Pro90 (my first digital) and the Canon 10D with 28-135 IS and 75-300 IS. The 10D and lenses work wonderfully well - marvellous sensor, great quality prints - but I have no faith any more in Canon. I have $6000 I had expected to spend on another 10D body and more lenses but this will go where I switch...

A dreadful shame because when they are good they are very, very good - but my impression is they just don't care any more so any further investment is contraindicated...

I didn't find this page until tonight. I have been using a Vivitar 283 connected to the hotshoe by cable with an ordinary (not sync-safe) adapter. It worked fine for about a year. Recently, the 283 seemed to develop a short circuit. i bought another used one and can't get it to work. I may have damaged the hotshoe circuit. The camera works fine as does the built in flash.

If that is the case, is it worth fixing? Can it be fixed.

Second question: Will the Canon Speedlite transmitter trigger a peanut flash on a non-Canon unit?

Any help much appreciated.

Thanks for an excellent sight. Trying to put my fears at ease after reading all the "should work" comments. I just purchased Canon G5. I currently shoot nikon F100 for film and want to eventually add Nikon digital slr to my setup. ? is can I fire my Nikon SB-28 with the extra pins taped on the G5 hotshoe or with my Nikon SC-17 extension sync cable? Also I've been reading about options for off camera firing with digital cameras. Anyone have experience yet with the Wein digital smart slaves or the Ikelite lite-link. These supposedly work with film or digital and would be cheaper than buying a new Canon 420Ex/550Ex. Finally, the voltage stats for the SB-28 are within range of the 6v powershot max. Would a wein safe sync take care of the proprietary pins and make taping them unnecessary? Could a standard hot shoe to hot shoe adapter take care of this since the voltage is within range? Sure appreciate any real world experience or suggestions. Thanks

Hi..I have a Canon Powershot Pro70 camera...I have a Albinar MDZ-80 electronic flash.
The voltage measures at +3.02 VDC for the triggering..I can't not get this to go "flash"
on this camera..

What I am asking here is ; Shouldn't I be able to use a digital ohm/voltmeter to measure
(detect) whether the camera's hotshoe circuitry in still "ok" to use?

I have learned that the left hand side "shoe -rail" has a " switch " ; built into along
the show rail that needs to be depressed...to activate a " 1/90 sec " shutter speed on
this camera (for use with non dedicated flashes)...

It also states you MUST select a manually selected f/stop (can't use F/stop AUTO MODE).

I can manually trigger the flash by shorting neg (shoe rails) to pos.center on the flash.

So my final question here is (Shouldn't I be able to connect the neg. lead from the
digital meter to the shoe rail.(I've put a wedge to push the switch contacts closed
to simulate the flash shoe closing the switch when inserted into the slide rails)
; then the pos. meter lead touch to the center (conductor)on the camera and fire
the shutter...and detect whether there's a close /open switching
happening ( to in essence symbolize the shorting out of the 2 leads on the flash?

Please let me know any of any suggestions..(Oh by the way this is my 1st post here ;
great site..every section of it !)...I am expecting a Used Canon Powershot Pro90 IS
camera bought off eBay.I have been reading ALL info I can about this camera..

Take care ; happy shooting and tinkering ( if you fix things relating to photography.)

Hello!

Just measured the trigger-voltage of my Cullmann DC36, built in the end-1980s (~1989).
The Trigger-voltage is 5.78V, so it's good for my digicam (Kodak's DC4800).
They tell their customers (in a hard to find support-page, http://www.kodak.com/global/en/service/tib/tib4319.shtml#SEC122-SUBSEC1) that there is a limit for trigger voltages down to 6V. And I hoped I can use my Hensel's Studio-Equipment (210V trigger) <sigh>.

Hope this is a little help

Topca 330AF -- 12.0V

It is voltage between central contact and contact in hot shoe rail. It was measured with digital and analog multimeter (2k/V). Digital one showed higher voltage. I believe it is due to higher input impedance of digital multimeter so it is more accurate.

I've got an old Sunpak model "auto266SR". It peaks at 5.7v measured with a good digital multimeter, with fresh NiMH batteries. I see it cycle down to 0v then back up to 5.7v in a couple of seconds when I test-fire it, so I'm pretty darned sure I'm measuring the voltage correctly. You can add it to the list if you'd like.

I have a mid 70's vintage Vivitar 283 flash (auto thyristor), made in Japan, s/n 5108247. I measured the trigger voltage at 215 V using my Radio Shack Digital Multimeter model 22-191. I had just put brand new AA batteries in the flash.

I also just called Olympus tech support to see if I can use my 215 V flash on my C5050 Zoom camera. The tech guy didn't know and neither did his mentor, but he called the headquarters and talked to an engineer. The engineer had tried that flash and said it would work as is. However, he recommended, just to be safe, to get a safe sync capacitor. Local photo stores don't sell one, but Wein supposedly makes one.

Hi, I have a G3 and a speedlite 380EX. I have been performing various tests in my equipment. First of all, strobe built-in assist beam doesn't really work with G3. I'm not sure about a firmware update to improve this feature. I'll take a look. I've heard that firmware update can be dangarous. You can halt your camera system completely if the update is not correct. Have you heard about this?
E-TTL works fine in all modes except "M" mode. The drawback is that f/2.0 is always set. I think using manual mode must be very dificult, as soon as, you have to set the aperture for each exposure. You have to check the object's distance and the strobe zoom, and know exactly each GN for each strobe zoom position. It must be tiresome.
I will continue testing my equipment and I will inform you of each news.
I still have a Wein safe sinc and I will test it with a non-dedicates Canon strobe.
Best Regards,
Roberto.

Thank you for this board. It has given me a wealth of information. I just measured the trigger voltage on my Sunpak 611 (unkown vintage, I bought it used). It was measured on the hot shoe auto attachment. I used a friend's top of the line Micronita (Radio Shack) digital multimeter with fresh batteries. The flash had new alkaline cells. At full charge, with the flash set at full power ratio, (man.) the trigger voltage reads 44.4 V. I also used my $29.95 cheapie and got a reading of 45 V. I think the theory about the varying quality of components is spot on.

Subject: Flash voltages for older units.

  • My older Sunpak 522 reads 26 volts.
  • My older Vivitar 283 reads at 262 volts.
I use both on my older mechanical Nikons and even on my new Fuji S602z digital. Fuji claims that you can use any automatic flash and they seem to be correct. Never had a problem and have used these flashes extensively. Aparently, Fuji incorporates an internal hot shoe based voltage reducer as part of their electronics. Excellent camera for a digital. They offer the first digital to have a built in hot shoe and have apparently taken the voltage problem into account.

I just wanted to say that I am looking at the PowerShot G3 and I found your "Secrets of PowerShot Flash Photography" quite helpful on the subject of making my old flash units work with the PowerShot.
I wanted to leave a tip for anyone setting up an off-camera studio strobe setup: Buy the cheapest strobe unit that you can safely mount on the hotshoe of your PowerShot. Use this as the trigger for the slaves on your external flashes. To avoid flooding the scene with the light from your mounted flash, cover the business end with unexposed slide film that has been processed. This will block the visible light but still trigger your slaves. Cool huh?

I measured the trigger voltage of my Agfatronic 280 CB flash and it seems to be at least 50 Volt.
(The internal resistance of my el'cheapo voltmeter is not high enough - when I measure at the 10 Volt scale it shows 2 Volt but on the 500 Volt scale it gives roughly 50 Volt - so the actual trigger voltage might be even higher.) Eek, no more use of that one on my EOS camera :-/

WOCTRON 2500PC: very cheap up-down/left-right swivelling flash unit. It's not thyristor based. Voltage at the hot shoe contacts is 5.5V (measured with DVM, 10 megohm input resistance). I am guessing that it's thyristor based cousin (2500SC) exhibits high contact voltage, although I didn't had the opportunity to test one. I am basing this assumption on the fact that, when a thyristor is used, the gate triggering voltage comes from the anode of the thyristor (which has high voltage). On such a cheap flash, most chances are that a special drive circuitry is not used and the anode voltage appears on the contacts.
So, if you are afraid of frying your camera, measure the 2500SC before buying. Otoh, 2500PC is entirely safe for any type of modern camera.

Canon US (after a bit of kicking - they started off with the "we don't support third party products and won't help" and I had to write a snooty email about their customer service motto to actually contact anyone who knew anything...!) confirmed by email that a G3 can be damaged by trigger voltages above 6v. They also said that the Wein-safe sync might help...

With the aid of a ($Aus10 ) multimeter, the voltage of my Cobra Auto 250 tested at 66V or thereabouts....while the accuracy of the meter is uncertain it would have to be very inaccurate indeed for this to be a safe unit!

As I couldn't find a safe-sync here in Australia, I am now using my flash as a slave with the aid of a second-hand bracket and a Wein peanut slave. With the G3 set on manual mode the flash will only fire once and the slave will fire correctly. (I think you can also set the flash manually in other modes, but I haven't tried it yet) Works pretty well - and the bracket balances a lot better than a hot-shoe mounted flash, although it does get in the way of the flip out screen a bit. The on board flash at low settings fills ou the shadows in the bounce nicely, and if i don't want that , I just cover it with my hand - the slave is blu-taced to the front of the flash so it still see enough reflected light to fire.

Your reviews stated that the Canon Powershot G1 and G2 were incompatible with Mac OS X. Rubbish! Just stick the camera in and open Image Capture or iPhoto and download the photos. Works with both cameras on all my machines (Powerbook G4, G4 and iMac). Just because Canon doesn't have Mac OS X drivers doesn't mean it won't work. Such an error makes me wonder what else you might have got incorrect on your otherwise brilliant reviews.

Steve <grabberslasher@hotmail.com>

At the time I wrote that, it was perfectly True. Since then Jaguar has appeared and while I use it every day, I've taken to linking my Canon to the XP machine. I'm currently using the Mac OSX Canon File Viewer Utility which is an okay OSX program but doesn't download movieclips from my G1. So I use the latest Zoombrowser EX under XP instead (talks to the Digital Elph/Ixus, too).

i have a canon g2 and a 420ex speedlite

in the past 2 weeks i have noticed that sometimes when i power up the camera and the flash, the camera seems to ignore the flash's presence and either does not fire (although the situation calls for a flash) or it fires with the shutter set at such a slow (non flash) speed that the image is obliterated by the flash

has anyone had problems with the physical hotshoe connection on the g2?

it does not appear to be broken and the flash locks down with the rotary clamp, but i get the impression that there is something "loose" in the connection which makes it not work soemtimes and work at other times

any experience, advice, suggestions would be most welcome

thank you for your time

Just got off the phone to Canon Australia (before finding your useful site I would say, as I'd only heard a whisper of potential problems with old flashes and canon digicams before I came here five minutes ago)...the person I spoke to there told me that there would be no danger using my old Cobra Auto 250 flash on my G3 (whether it works or not is a different issue!), despite neither her nor I having a clue of the trigger voltage.(ie similar advice to that from Canon Canada)...but after reading this site, I'm not game to try it without either having checked the voltage or having it in writing from Canon so that I can get any repairs done under warranty......
Has anyone actually fried the circuits in a G3 using a high voltage flash? And as I don't have the equipment to test the voltage myself, has anyone tried/tested this Cobra flash, or have an email adress for Cobra, who are also UK based. (flash was purchased in Australia, - and I don't want to have to make a series of international phone calls to track the info down!!)

Hi there,
I measured the voltages on 2 flasguns. My Olympus T32 that I bought in 1980 gave a reading of between 9.5 and 11.3 volts. For some reason I got lower readings using new Duracell batteries than batteries from the same batch that were partly used!. Anyway, the voltages were not stable during measurement.

I next measured the voltage from a small UNOMAT B20C Flashgun which takes 2 AA batteries. I got a reading of 210 volts!

I used a new HILKA Digital Multimeter with an input impedance of 10 M ohms to take the measurements. When I used an old AVO multimeter of unknown impedance I got readings of about 2.5 volts - I did not trust them.

I have used the T32 on my Canon G3 and as I have not been having problems I will continue to risk it. I tried to use the Unomat, but it would not fire - probably just as well. Maybe the G3 has a cut-off mechanism to detect higher voltages?.

Thank you for your information about strobe voltages. However, you did not have the data on the strobe that I needed, so I contacted the company, Sunpak at "tocadamerica" <tocadamerica@msn.com> with my question, "Can you tell me how many volts the Sunpak model 522 come into
contact with the camera plug?" The response I received was "Usually 190 volts dc- not recommended with modern electronic cameras."
Keep up the good work.

The trigger voltage on my newer Vivitar 285HV measured around 8V, whereas it measured around 195V on my old Sunpak 522, and 265V on my ancient Vivitar 283! Thanks for providing information regarding this sort of thing.

(Not on your chart)

Vivitar Series 1, 600 M/P/O (dedicated to Minolta, Pentax, Olympus TTL), guide number 120, zoom, 270 degree swivel, & tilt flash-head.

Trigger Voltage - 8.7 volts.

Works exceptionally well on Sony DSC-F717 with the flash's own flash sensor. (No TTL capalbe hot-shoe on the F717.)

Thankfully I ran into this site before heavily using my newly acquired Minolta X-700 camera with an old Achiever 260T flash.

I measured 253 volts with my Fluke multimeter.

Hopefully using this 3-4 times with my X-700 didn't damage anything....

Hello,

I am wondering if you know if there is any way to trigger an external non-Canon flash using the Canon G3. I will be using the G3 in studio. Instead of using the flash built into the camera, I want to use my Norman studio lights.

Right now I use Kodak cameras that have PC synch cord outlets. Thats just wonderful, but the cameras are getting old and unreliable.

So far I have been told that there is a "hot-shoe/PC adapter" will allow me to use your G3 with studio strobes. Do you know where I can buy this adpater? I assume it's third-party because Canon told me their hot-shoe cord only connects to Canon strobes.

Heres another question:

When my Kodak DC-4800 is too far for a synch cord, I just use the built in flash in the camera. That flash triggers the $15 slave trigger attached to my Norman powerpack and they all go off together and somehow the exposure is always right on. Can I do that with the G3? (Ive tried this with other cameras and didnt work. Apparently there is a lag between their shutter and external flash and the light from the external flash never reaches the CCD).

I am posting a copy of this to the newsgroup also, but I thought I write to you directly since you are the Canon strobe expert.


Thanks a bunch,

Crispy

Yes, there is a preflash lag on all ETTL strobe units

Unfortunately, at this time we do not have any flashes or interface modules

Although there is nothing in production at this time, digital dedicated
flashes and modules are under development, and we hope to have something
available in the near future. Please check our web site, www.sunpak.com

How much flash trigger voltage can a camera take?

Pentax, in reply to an inquiry I made directly to them last year, says their SLRs are safe up to 600 volts, but I have learned from the College of Hard Knocks that the PZ-1 and SF-10 lock up when used with a Vivitar 2800 non-dedicated flash (300 volts), and won't work again unless the battery is removed and the camera allowed to sit a few minutes for the circuitry to reset.

SOME cameras with electronically controlled shutters and programmed flash still used hardwired tungsten flash sync contacts safe to hundreds of volts, example: Pentax LX.

I have two important questions. I am shooting jewelry close-ups with a Nikon CoolPics 4500. I have a database I designed in access to store the pictures and info.

1) I have been looking all over the web trying to find a Twain source for the Nikon CoolPics 4500 camera so I can directly input the images from the camera to the computer via the USB cable. Is there such a thing for the Nikon CoolPics 4500?? Is the Nikon Capture software designed for this? If so, is there a version for the CoolPics 4500 camera?

2) I have been using some pastel backgrounds for my jewelry shots in order to select the foreground, but the pastel colors reflect on to the piece. Is there a method of foreground selection that is better suited for jewelry?

Thank you in advance for your attention.

I have measured the voltages on the pins of a Contax TLA20 flash, to check the accuracy of the report already posted on your web site. I checked these voltages in both Lo and Hi settings, but not the AUTO setting. Both results are the same. I used a Hewlett Packard E2378A digital multimeter, which should have a fairly high impedence. The voltage after charging is 4.2 volts on the central pin. When the flash is discharged the voltage goes to zero, and then gradually rises again to 4.2 V. One of the other pins charges to 3.8 V at full charge, also discharging essentially
to zero on discharge. (See pin diagram below.) All voltages are positive, and measured with respect to the slide contact on the hot shoe. Hope this is clear. Of course a multimeter cannot check for short, high-voltage pulses.

(This pin shows about 0.2 V at full charge) x x (This pin shows 3.8 V at full flash charge.)

The voltage on my newly acquired Vivitar 3500 with Canon DM/C module was 9.36 volts. Used both analog and digital meters. Didn't matter much whether I used the 10 volt or the 250 volt range. All meters over $10 are at least 20k ohms per volt sensitivity and even the 10 volt range was 200k ohms. So we can get as much as 1 milliamp if we pin the needle on the 10 volt range with a 200 volt input, so what? Converting a HV flash to LV is just a matter of opening the unit and adding a sub-dollar SCR.

Kevin,
Thanks for sharing insights into using Canon G1/G2 with strobes. I'm surprized that even with a dedicated flash that my G2 will be limited to wide open (or tricked F8) aperature. If I understand this correctly, if I did buy a Canon 420EX flash, I will still be using it in manual mode for most daylight fill flash situations! Amazing.

I measured my Sunpak 36DX at 5.86 volts, about twice as high as the entry on the list. They seem to have a lot of variation, so someone thinking of using one should certainly measure their own unit.

It seems like it would be possible to put a small resistor in series with the flash shoe to bring the resistance down, no?

Thanks for the great service!

Actually, all electronics need to have a current or no electrons will flow and nothing will happen. The current only flows during the moment of exposure — but the different electronic potentials between the two poles will be there, and is measured as the voltage.

Sometimes the stobes will fire using this set up and sometimes they won't... Any idea about what I am doing wrong? Do you think I have a short somewhere? (I put the camera on M mode and set the "shutter speed" to 60 and the aperture to 5.6.) When it works the results are great!!! I am just looking for some consistancy. I would love to rely on the G2 to check my lighting for medium format work. Thanks for your great site!

You are providing a great public service with your flash voltages page. I did pop off my flash one time before I managed to figure out that it wasn't a good idea. I hope I haven't ruined my brand new Oly C-5050! I tested my (China) Vivitar 283 at 8.5 Volts. I'd like to point out that the safe sync accessory that is sold by Olympus (at least as far as I can tell) reports to regulate the trigger voltage at 11.5 Volts. I assume that anything less should be safe for the camera, but there is really no confirming this. At any rate, I am proceeding with extreme caution. I wish the manufacturers provided better information on safe sync voltages!

Hello Kevin. I've been wondering about that long low picture of Iolani Palace in your gallery. It seems to be very high resolution. It has a sort of classical "etched" quality that I like for that subject. I've printed it at 6.6 inches x 26 inches and even at that size it looks good. How can that be?? Can a single G2 shot be printed 26 inches long and still look good? Is that picture cropped from a single G2 shot -- or is it a mosaic stiched togeather? I would like to hear the story of that picture.

Hey, I found your site this evening and it's wonderfully full of help & good links. I just got a Canon G2 and strobe lighting system (umbrellas etc.) with the Wein adapter for $40. I was glad to read about your details on the voltage and how the $40 saves me in potential problems. I do have a question about the LensMate adapter. What can I do with it? I want to get into portrait photography and I'm taking a class at a community college this month on digital photography, which I believe gets into Photoshop quite a bit. Will the LensMate help me in any other way? Is the Olympus A-200 Tele Lens a good deal at $85 and will this add to my new experience in digital photography? I think this is a telephoto lens. Thanks!

I have just measured the trigger voltage on an Agfatronic 320 CBS and found it to be 250 volts.
Unfortunately, I wasn't aware of the trigger voltage problem when I first tried the unit on my new G2. When I fitted the strobe, the flash symbol disappeared from the LCD on the camera and neither flash fired. Removing the strobe brought the camera back to normal operation but I am now not sure as to whether the hot-shoe contacts are still working. Can you tell me if there is any way of checking this out without going out and buying a 420ex strobe, which is something I am not in a position to do at this moment.
P.S. I have read the instruction manual from front to back and can not find any mention of this problem other than the fact that some strobes may not fire at all.
Any assistance would be gratefully received,

Hi.
What are these Jap boys playing at. They design two strobes,the 283 and 285.Both are physically the same almost the same specs yet the 283 trigger voltage is 300+ and the 285 is 8v. Do they say to themselves "got a day to spare,lets design a new circuit". You know what they say about the oriental mind

I measured my Vivitar 283 flashes trigger voltage at 241.3 volts. This is a 20+ year old flash with a serial number of 8397929.

Just for the record.

I measured my Minolta Auto 28 and got 43 volts (open circuit) with my digital voltmeter.
This is in contradiction to the 200 volts as measured by Wes Quigley. Maybe my flash is
of a newer production.

reading the botzilla.com/photo/g1strobe.html article, i noticed the part about firing a slave strobe, sing a Canon G1. The problem that E-TTL always fires a pre-flash, can perhaps also be solved by using a slave flash like the Soligor DG-20 A (www.soligor.de). It can be set to skip 1, 2, or 3 pre-flashes, before it will fire.

Susan Doel at Lensmate is soon to start marketing a lens adapter for the G3. There are two models. One has 52mm threads on the front, the other has 58mm threads. I will be purchasing the 52mm one, as I have been impressed with the use of the 49mm adapter on my G1. I look forward to testing my lenses (Olympus B-300, A28, etc) with this adapter and reporting the results.

Hi,

Here is one to add to your list of Flash voltages of the various Flashers.
I recently bought a second hand SUNPAK Power Zoom 4000 AF for my NIKON Coolpix 995 camera.
After having measured the trigger voltage on the connector pins, while the flasher was "ON" and ready to "trigger", I knew it was a safe one to use in accordance with the NIKON specifications.

The measured voltage was never higher than 3,6V, so I would say; This one is more powerfull than the ones from the SB-xx series of NIKON and costs about half the price of a NIKON SB-xx flasher.
Because a NIKON COOLPIX camera does not have the right electronics to control the zoom and the IR measurement functions of the NIKON SB-xx(DX) flashers ( as I was told by a Nikon sales representative), the choice is easy: A SUNPAK Power Zoom 4000 AF does his job very well, when switched to TTL control. However also this Flasher does not give you the benefit of it's zoom feature, it still works fine on my NIKON COOLPIX 995 camera. In fact this should work on all coolpix 9xx camera's.

So resuming I would say; ADD this one to your safe list of flashers for the Nikon coolpics 9xx camera's.

I hope that a lot of your readers can take benefit of this experience.

With regards, Kees

Having been an enthusiastic amateur using SLR's up to Mamiya 6x7 and my darkroom, I have now 'discovered' the advantages of Digital using a Canon G1. My point: A basic rule at any camera club to which I belonged was "Always, always use a lens hood" I'm sure any 'serious' amateur/professional would agree. I haven't (a) been able to source a hood for the G1 and (b)seen this point covered on the forums. Anybody know if a hood is available for the G1,G2? I know the hood can only be fully effective at the wide end of the zoom but it really can improve quality (as does stopping down two stops from the open aperture)

I just bought two Vivitar 285HV flashes and checked both using a Micronta (Radio Shack) digital multimeter. Both were a few mV under 8 V. Both are made in China.

Thanks for the web page on flash trigger voltages. I finally decided to get an external flash for my somewhat dated Kodak DC290 and was a bit concerned about the flash trigger voltage knowing that an old flash that I have was several hundred volts. I never measured it but was bit by it once when using it for a stop-action picture. I tried a 285HV on the DC290 and it works fine. (The other is a Christmas present for my daughter.)

So I have received my Fuji S602 and have had the weekend to fiddle around with it. New to REAL photography, but I am so glad I finally dished out the money for this. I got it for a steal <$500 on Ebay (dont worry its new with US warranty), so the money I saved I used to buy the adapter lenses and a circular polarizer and uv filter. Also got a nice portable lightweight tripod and 128mb card. Ok well now I need to know more about the Flashes that are available for my camera. I know this site is for Canon (which I opted away from since super Macro shots are something I really am interested in) but I was hoping to get some expert feedback before I buy a flash. I know that Phoenix Makes a flash ($50 online) but I dont know how good it compares to a Canon flash or any others for that matter. I know you get what you pay for but I am looking for a bargain purchase since cash is tight for the holidays. Any suggestions or comments on the phoenix would be great.

BTW I love my camera so far. Makes the learning curve much faster by going digital. I have some great images so far but besides that I love the fact that I immediately see the results of my adjustments with the settings.... no waiting for the film to get developed.

Thanks in advance for your help

I have tested my Metz 32 Z-2 with standard shoe, the voltage was 4.086V, which is safe for the DC.
The Leica CF flash voltage was 10~11V. And with Metz 32 Z-2 & Canon 420EX, I have found that;

1. The G2 was able to take pictures even the shutter speed had set between 1/250 to 1/1000s in M & Tv mode for high speed photo (Panansonic LC-5 too).

2. When using the Canon 420EX, the LEDs on the flash shown 28mm at wide (camera set at 34mm) & 70 at tele (camera set at 102mm). I do not know is this normal ( trying to find out).

With my old Nikon camera (the days when built-in light meter was the only eletronic part in the camera), I always liked to use two flashes: a stronger flash like Metz 60CT to bounce from the ceiling and a small flash for direct light. I just use a "Y" splitter with the pc connection. It worked similar to a Metz 60CT4 flash.
Now with my setup: Nikon 8008 with Sunpak 555 + Photogenic PL1250 strobe (or other flashes for that matter). They will miss fire most of the time.
What was the problem?
I suspect it is the voltage difference or over the limit of the Nikon camera?
I wonder if a voltage regulator like Wein safe sync H will help.
If you have any insight or experience with this, please advice.

Well.. not really a cry for help. Just a follow up on my previous cry.

I did email Canon (in Australia, because that is where I was), but no replies that I can remember.

I finally did pick up a CF card reader.

Just recently I picked up an IBM 1Gb Microdrive (with travelkit).
Great for laptops with PCMIA cards.
Not as great as it could be if your card reader does not support CFII.

So, first lession, get a CF card reader (USB)... its worth it!
Secondly, make sure its capable of CFII. I mean, c'mon, you just dished out for
the G2 (or G3), may as well through in the goodies by getting a CFII reader that can handle that
possibility of the big ass microdrive.

Now that I've experienced the magic of a hi res digital camera, I'd really be keen to get more of a truer SLR digital camera.. the kind that is a just a body, and I can plug in my own EOS lenses for telephoto, wide angle and even fisheye, if I wanted. Its all just a bit out of my price range at the moment. Oh, and I am aware of the accessory lenses that are available. I'll be getting thse in due course.

Hi I just got into digital photography, well to be honest photography as a whole, earlier today. Ok to be correct... A FUJI S602 is on its way by UPS as we speak. My question is what flash is the best value for this particular camera. I see that Fuji makes one for it ($20 online) but it looks to be a very poor flash. I would like a flash to handle everything I need and not screw up my camera electronically (see things about voltage on this site ... scares me to think my precious item could be destroyed by trying to just use an attachment on it). So if anyone could suggest a good, safe, and cheap flash for me to learn with I would be greatly indebted! Thanks in advance.

The Quantaray QTB 9500A was tested at 4.93 volts. This is a modular flash that can be used with a number of different cameras by changing the base module. Because the Quantray 7500 and 6500 models use the same base modules as the 9500, do you think they would have the voltage as the 9500?

I was reading Kevin Bjorke's article on g1's f/8 trick http://www.botzilla.com/photo/g1faq.html. I tried the same thing on my g3 and found it still works on g3. On g3 turn on flash, use Tv mode and set shutter speed to 1/1600 or 1/2000, the camera will take picture at shutter speed of 1/250, max sync speed?, and aperture of f/8. If you select other shutter speed between 1/250 and 1/1600. The camera will choose aperture bewteen max aperture, ie. f2 at wide angle and f3 at tele and f/8. The higher the shutter speed, the smaller aperture. The camera fired the right amount of flash to correct expose the subject for all the test. I believe same thing is true for 420ex and 550ex attached to g3. As pointed out by Kevin, this trick can be used for macro work to enhance DOF. This essentially give photographer a way to be able to select DOF and still take advantage of e-ttl's auto flash. And a big plus for g3, the LCD will NOT go dark as it did on g1.

Interesting and unexpected.

>Can you now comment on Phoenix D79-BZS Flash ?/?

Dave,
Oh.. sorry please exhale !

First I must say that I have avoided using a flash all the years I've done my 35mm B&W photography so using one is NEW to me. That is... I'm no expert at it YET ! (GRIN) But since I've made the switch to digital, hey.. might as well explore even farther.

So far, I've found the D79-BZS to be able to do everything a flash should do. I was testing it indoors and outdoors, with some available light and also in the total darkness.

As an example of power, I had great lighting outdoors across a pool, in pool area lighting that was too dark to AF in, but the Phoenix set to telephoto threw more than enough light for the scene. It also covered the outside of a two story house that was in total darkness on another shot.

Then I shot frame filling faces indoors using the bounce and produced what my eye sees as a very nice exposure. I DO think I'll be getting one of the clip on bounce defusers for extra control in some cases, as you can't always depend on a good surface to bounce off of.

I'm sure I will get much better at using it, but so far it has worked very well for me (150 shots +or-). Batteries were still going strong BTW and unit was recycling VERY fast still.

Any shots that could have been better were MY fault as I was trying out various settings on manual mode on my Fuji S602z. I mostly allowed the camera to auto set the white balance, but I'm sure doing a custom WB before shooting would help a bunch. Manual mode is the way to go using the flash though since these flash units do not communicate with the camera.

I DID love the fact that it is also a slave flash and I could hold it over my head, or down low with the internal flash as a trigger. Also comes with a base so you could stand the unit off to the side or for backlight etc.

So far, I have no complaints. I'm sure that spending two or three times the money would get better unit but I would never do that.

I still like to work with available light whenever I can, and mine will no doubt be used more for a fill on slave setting.

Unfortunately, we will probably never hear a report from an expert/professional (that's not paid to say so) on the unit as it doesn't cost enough LOL

But then, I don't need to know any more, it works for me..

Hi, to the guy with the noisy G2. I have read of this before. I read one girl retirned hers to the store and tried another G2 which did not make the noise. I listened in the store when I bought mine but it was so loud in there I heard nothing. Sure enough though, mine too makes this noise. It is most noticable when the lens retracts at power down. I would describe it as a dull chattering noise, definately not a grinding noise. It sounds like something is loose and vibrating. My camera preforms perfectly also. I have a feeling its a design flaw and is very common.

My Canon G2, since purchasing in late May of this year, has made an intermittant "mechanical chattering" sound during the power cycle. It sounds as if the plastic lens barrel is dragging against the camera body as the lens extends and retracts. The sound is louder during "power down" and is amplified by the lens adapter. The chattering is louder than the normal motor and apurture sounds. I believe that the chattering has become louder but I may have just become more sensitive to the issue. Otherwise, the camera has performed flawlessly.

I have asked several local dealers and have received answers ranging from "no problem" to "live with it" to "send it in before the warranty expires" to "send it in now".

I'm new to photography, and therefore digital photography. My desire stems from a need to get photos on to my church web site in an easy and timely manner. As is so wisely stated in your web site somewhere, I am merely a Canon G2 owner, not a photographer.

My problem is light, not enough of it (in the church). I am obviously in need of a flash attachment (photographers I'm finding call them strobes). I've read virtually all of your photo related web site, especially all of the flash stuff.

I can't/don't want to afford a Speedlite and have been looking at the Quantaray PZ-1. After reading your site I'm still not sure about whether this particular model would be 'safe' and what would be the draw backs.

So, let me cut to the chase, can you speak directly to the case of a G2 and the PZ-1?

Finally got this Email answer to my trigger voltage question from "Phoenix" as I did not see them listed here, I thought I would post this. Hope it's of some help to someone..

From Phoenix Corp:

The D79-BZS uses a thyristor to trigger the flash tube, hence the voltage measure is about 6 V. However, the actually trigger voltage seen by the thyristor is about 3.5 V. You can use it without the preflash or with.

I'm travelling around at the moment, with my G2 and laptop. Frequently, I like to download the photos off the camera and put them on the laptop (running Win2000).

Unfortunately, I had to uninstall Zoombrowser EX. But I thought, no worries, the camera will appear as a device in the Explorer, and I can just drag and drop the images and files. Well, no such luck. I can still get images, via Photoshop (TWAIN and all of that), but my movie files are stuck on the camera.

Does anyone know of an alternatives to Zoombrowser EX that will let me download the .avi files from the camera to the laptop?

I operate a Canon Powershot Pro90 IS. Great pictures, great use of lens. Disappointing news from Canon. I purchased a Canon 550EX flash for the purpose of using this flash as a slave(off camera). Canon has returned my email stating that the wireless transmitter ST-E2 will not function with a Pro 90.

Has anyone attempted or are they using a 550EX with a Pro90 and a ST-E2 wireless transmitter?

If so, please let me know.

I just discovered your site and wanted to see if other Canon users have noted a color "interpretation" problem with their G1. My G1 is a gem. Under most circumstances it is a miracle of modern technology and meets all my amateurish photo needs. However, my G1 goes completely bonkers when the array is exposed to a brilliant magenta color. There seems to be a certain red frequency that drives the color interpretation nuts. The first effext I noticed was blooming. Then, as I tried different reds, I noticed that it simply will not reproduce certain of them, displaying an off shade that it chooses to represent anything it can't master. Weird.

I chose the Canon digital camera because I have used Canon glass cameras since the early 60's. I have found that NOTHING captures the essence of human skin as well as the Canon optical system. I tried Nikon, Minolta, etc., but no one comes as close to true color reproduction as Canon. Naturally, I was mystified about the problems I've experienced with my G1 color rendition.

Oh. As a by-the-way, I have many years experience with the design of military Infrared and UV real-time imaging systems. I do suspect that the problem is related to the array material and it sensitivity to certain wavelengths.

One problem, recently pointed out to me by my friend Jawed Ashraf, is that digicams often respond in unusual way to certain colors not because of the visible portion of the color, but because of infrared. The reaction is particularly noticeable with synthetic fabrics like, say, soccer uniforms. The extra IR gets incorrectly interpreted and interpolated-into the resultant colors. A nasty problem!

After my first G2 had the 'stuck controls' syndrome right out of the box, I can gladly report I have received a replacement G2 that works just fine. The next thing was to check if the so-called f/8 trick worked with my 420EX flash. What I found was that in Tv mode if I chose 1/500th sec it would result in f/2, then at 1/640th sec results in f/2.8, then at 1/800th sec results in f/4 and finally 1/1000th sec in f/8. In all cases the ACTUAL shutter speed stayed constant at 1/250th sec. There are no sync problems at that speed with the 420EX. So it is simply a matter of varying the 'shutter speed' (which it doesn't)to set the f/stop from f/2 to f/8. Obviously the E-TTL adjusts the output and at f/8 I was able to take flash photos at greater distance than 6 metres (not bounce). No problem with depth-of-field, which I can now control.

Yup, it does indeed look like they have improved the flash handling in the G2 a great deal over the G1.

I have today just bought a G2 - took it home and inserted battery and charged it up. But when I turned it ON I was greeted with a Set Date/Time screen, and found that ALL rear controls are completely frozen. This G2 is totally inoperable. Needless to say I am NOT HAPPY! Now I've found that others have recently had the same problem, came across this: http://photography-on-the.net/forum/viewtopic.php?TopicID=3051 "Stuck Controls"

There are others I could point to.

It looks like there is a bad batch of G2's out there. I noticed as well that the latest firmware 1.1.0.0 was, according to Canon's own site, released 19th April. Could it be a coincidence that the faulty G2's have appeared since then? If it is, do NOT upgrade your firmware until this is sorted out. Even of more concern is that Canon has not seen fit to recognize there is a problem?

Have anyone here experienced this? It seems we are talking very recently made and bought G2's.

Canon's flashlight 160E and 200E can also be used on the PowerShot G1. A special fix in the firmware version 1.0.0.1 has been made for these flashlights. Triggering voltage is unknown to me but they must be below the required 6V. The official text in the firmware path is : "Speedlites 160E/ 200E will now flash when mounted on the PowerShot G1. But, as they are not EX-series Speedlites, they will fire at full strength. (Automatic flash exposure with the PowerShot G1 is only possible using the built-in flash or an EX-series Speedlite.)"

Thanks for your very useful page, which I came upon by accident reading posts on the DP Review message list for the G2, only after having used my old Sunpak 422D on my new Canon G2 for several shots. I tested the trigger voltage using your method, and found it to vary between 5.0v and 5.5v--to my great relief. Not sure that applies to all 422D's, but that's what mine measures, using four 1.5v lithium batteries and the NE-1D shoe.

I purchased a Sigma EF-500 Super flash made for the canon....it does not work with the Pro90IS at all....After I bought it I read at this site, that the Canon flashes don't work with it either. I called Sigma and they informed me it probably would not work with the Pro90, and it was primarily built for SLRs.I called Canon and they said the 420ex and the 550ex will work with thew Pro 90.I told them that I saw comments, from very unhappy Pro90 owners,that neither of their flashes worked with it. Their answer was the cameras were most likely damaged by using the wrong flash,and would have to be sent back for repair.I hope that the company I bought the flash from will let me return it.....Frank

Boy! Am I glad your site exists! I am soon to take possession of an Elan II bought via eBay and have flash guns (strobe for you Yanks) which would have fried the flash trigger circuit. I will build the opt-isolated trigger described in the 'Strobe FAQ' reached via your link. In return, here are the voltages measured on my three Metz flash units:

  • Metz 202 --> 200 volt !!!!
  • Metz 402 --> 190 volt !!
  • Metz 402 --> 202 volt !!!

I have other el cheapo units which I sometimes use to remote-trigger the other units in a studio-like setup but your readers are unlikely to get hold of these exact flash guns so I haven't listed them.
Thanks for saving my bacon!

I checked a new Vivitar 285HV with Quest rechargable batteries and got 13.31 volts. I have burnt the sync out of two Pentax AF bodies in the last year. I shoot mostly on beach with flash fill. I solved the problem by buy a Nikon FM2 and a Fuji 670 for my flash work. These cameras show no problems and it fun to tell the camera what to do for a change. I use a Sun ringlight on a Fuji 6900 digital camera. So far no problems This is a wonderful site. This is info that needs to get to the public.Thanks for all the effort......

I read with the highest interest the voltages measured on the above mentionned unit. Almost had a heart attack! 300 volts! Okay, I am not using an EOS, but a Minolta X-700 which has TTL flash control and so on and it seems that the Minolta 280PX dedicated to that particular body measured 1.8 volts only. Well, I checked my Philips P36TLS, with a Beckman Industrial DM27XL digital meter, here are the results:

  1. with 4 Ni-Cads AA, measuring 1.26 volts each, the voltage at the hotshoe reached 5.04 volts after about 3 minutes. (I could not wait much more because that flash turns itself off after some time.
  2. Not satisfied, I put 4 fresh zinc-carbon AA batteries, known to have a higher voltage than a Ni-Cad while new. I then discharged the flash and let it charge again. Each AA measured 1.672 volts, and the measured voltage at the hotshoe, after 3 minutes again, was 5.64 volts.
Thus, in the worst case, voltage is under 6 volts, which should be okay for any camera.
By the way, I am looking for instructions as how to set that flash on auto mode and select the proper aperture and range. If someone has info, please drop me a line at jesl1905@yahoo.ca Regards.

Is there a way to get the aperture and shutter speed to show in AV mode?
Of course in manual mode it shows both settings.

Considering your advice (http://www.botzilla.com/photo/g1strobe.html) I bought the Wein safe-sync hot shoe mounted high voltage sync regulator. (Thats the one that mounts on the hot-shoe mount and has a pc sync chord output in front. PROBLEM! Not only does it not work (it doesn't trigger the flash system I have it conected to), my camera(pro 90 IS)makes a high pitched sound when I mount the unit on the hot shoe (strange huh). Has anyone else had this problem? I suggest you either remove your advice to buy this product for these cameras OR tell me what dumb thing I'm doing wrong! Great site, by the way, and THANKS!

I own a Canon Speedlite 577G (potato masher)that I use with my half dozen 70s and 80s Canon cameras. I love it, and it is spectacularly versatile and nearly foolproof with my vintage 35mm equipment.
I would like to buy a Canon G1, but do not know if the 577G is compatible with it. I do not have the test equipment or talent to check the trigger voltage of the unit.
Has someone done a test on the 577G to determine the trigger voltage? I will be really disappointed if I can't use the 577G with the G1 and will go with a much less versatile and less expensive (cheap)digital camera if I can't.

Please change the "colors of the threads" on this site!! The red lettering is very, very hard on the eyes when reading and the background colors does not help. You will have to goto colors that are comfortable and easier to read. I have a PowerShot G2. I like reading the various comments but I can only read a few due to your sites difficult color (clash) combinations. One would think that a "photographer" should know the affects colors can have on the eyes. Please take this as a constructive criticism.

Sun, 17 Mar 02 at 22:13:47

Okay, so I'm still confused. After going over your website it appears the G1 is fully capable of utilizing external flashes including studio strobes, yet user responses in the Canon FAQ on Digital Camera Review indicate there is a 4-5 stop diffence between what a flash meter reads and what the G1 exposes. Some users even go as far as saying that it won't work.
I would very much like to purchase a G1, however, I need to be able to reliably use it like a polaroid back to 'proof' lighting configurations for portraits and commercial shots. I own a host of EOS 35mm equipment which will be used for the finished product.
So, I guess the questions remain - Will the G1 work with monolights (White Lightnings) and will I be able to acheive properly exposed pictures using the readings from my Sekonic meter? Shouldn't f8 @125 be the same on my meter, my EOS3 and a G1.
I need help - can you tell?! Any light you can shed on this subject would be GREATLY appreciated!!

An exposure is an exposure, though any digicam will have its own characteristics, just as shooting Kodachrome is different from shooting Fuji NPH. Practice and tune your work to get the sorts of predicatable results you like.

Hi-- I received a Canon PowerShot G1 in December 2001, and have yet to find a way to attach it to my Windows Me system. The computer seizes up every time I attach the USB cable. Then I have to use the startup disk and system restore to get going again. I've tried to use the Canon driver update, but it seems that windows just doesn't recognize the hardware. Has anyone else had -- and solved -- this or a similar problem?

I can't thank you enough. I might have fried my new G2. My 70's era Vivitar 283 (Japan S#:6033673) measured in at a range of 150-250 volts - I guess that's where the batteries have been going all these years! My measurements were made usng a Micronta digital multimeter (Radio Shack model 22-193) once the flash had fully charged (blinking ready light). I guess my 283 is destined to spend it's (already long) life with it's age-old companion - my Canon FTBn. BTW... Great site! An incredible source of G1/G2 info and techniques.

The G1's f8 flash trick definitely works on the G2. However, you can also use Av mode, set at f8, and the flash works as close as you like, on auto, so the trick is not really necessary.

Re Voltage of Vivitar 285:
I am not sure I tested the voltage properly on these units. I simply took the negative lead from my digital meter, held it on the side of the pc cord, and touched the red (positive) lead to the centre pin on the bottom of the hot shoe.
All 285 HV's...flash # 1 read 33, the second flash red 20, and the third flash unit read 8.3.
Firstly, could someone let me know if I did this correctly...and secondly, why would 3 different units read so far apart. I have an Olympus 2100, and an Olympus E-10, and seem to be confused as to whether or not any of these are appropriate for these cameras.

Hi together, her comes something negative about the software for the "PowerShotG1"
Im asking myself, why nobody has realised yet, that the CANON "ZoomBrowserEX" has the following, great disadvantage: This program doesnt display the Thumbnail from a "AVI"-Movie that hasnt been downloaded directly from the Kamera through the ZoomBrowserEx itself. Didnt you ever have been aware of this stupid handicap? Even if I "shift" (with the "Windows Explorer") a AVI-Movie out of a ZoomBrowser-Folder to an other Folder which isnt part of the ZommBrowser-Library, and "shift" back again, there occurs the same effect: no more thumbnail is shown of this Movie. Unbelieveable! Okay, what can I do, to bring the Thumbnail of a AVI-Movie from "extern" back? Who has a answer for this question? Please tell me, how to solve this problem.... Im waiting. Thanks.

I have a hotshoe pc adapter that works fine with my Sunpak 522 but with the Norman system, I depress the shutter release and the LED goes blank (the battery symbol flashes like a dead battery). I depress the shutter release again and the LED comes back on but nothing flashed. The Elan 7 seems to work ok with other flash units so I don't think I 'fried' anything. I visited a couple of camera shops with my situation but all the sales help I've talked to didn't seem to understand what the problem would be. Where do I go from here??

Hello! I was wondering if you have any tipp on how to take better pictures with my G1 when it comes objects that are in color red (255,0,0) or that are close to it. You can see several shots on my webpage where the red turned into SOLID magenta, and as a result also resulted in reduced or NO details where it is magenta.
Do you think, that it is normal to get results like this from the G1 that costed me nearly $900 in November of 2000, meanwhile a cheesy Kodak DC200plus (4 years old) can make perfect shots of the same red objects without the touch of magenta at all. I am curious to hear your answer, opinion and hints if you have any. I red your FAQs on G1, but couldn't found any reference to this RED<turnsinto>MAGENTA problem. (infringing is a different problem, I believe) Sincerely, Geza

I have made about 200 exposures with the Sunpak 383 super ... no problems ... I don't worry about it anymore! joe

Hi!
Here are some trigger voltages:

I mailed to Metz to ask their opinion of connecting Metz 45CL4 to Canon Powershot G2 and here are their answers:

A suitable adapter dedicated to the camera Canon G2 is in preparation and will be launched on the marcket approximately in april this year.

Unfortunately, any further details like flash features etc. are still unknown in this matter. Until the new adapter is coming, the flash unit Metz 45CL-4 can be used in automatic flash mode on your camera G2. For that, the flash unit has to be connected by use of a sync cable called 45-54 and the camera has to left the program working in manual mode.

After speaking to Quantum Instruments about using their T2 flash with the Canon EOS D30 I was told it was OK. The triggering voltage for the T2 flash units is 8 voltage according the Quantum tech support. Although the D30 has a recommended voltage of 6 volts Quantum maintains that the low amperage on the T2 would not cause any problems on any of the EOS cameras using a direct pc connecting cable.

Just to verify, the three readings on flash units that I posted were serious and measured from the ground contact on the side of the shoe to the center pin; though the method/conditions were not.
I took my VOM and four fresh alkaline batteries to my friendly used camera store today and checked out four of the flashes they had for sale. Two were way overvoltage, one was very near 6vdc and the fourth, which I purchased, was way under.
Olympus T-20 2.6 vdc
Since this is way out of line with the previous measurement posted for the same unit, I replaced the batteries with a different brand and got the same results. This leads me to believe that the manufacturer(s) do not put much stock in their components and purchase the cheapest available at the time, thus resulting in marked differences in production runs. This added to the difference in usage in used units makes it reasonable to do as I did and make your measurement prior to purchase of any used unit.

Figured that I would check the other flashes while I was at it-
Phoenix BIF 82C 6.o (six) vdc
Soligor 30DA 5.25 (five and one quarter) vdc
trigger voltages
all measured with an antique Qugami Supra Deluxe Combination Volt-Ohm-Meter/Screen Door Tensioner with questionable batteries at twilight - 31 degrees F outdoor/68.4 degrees F indoor under 2000 watts of 3200 degree halogen lighting which were turned off at the time.

Thank You So Much for your table on flash trigger voltages. it was a great help. Using your outlined method I tested my Sigma Super EF-430 and got a trigger voltage of 4.74. My Vivitar zoom 2500 gave me a trigger voltage of 13.10 and finally my 3 Photogenic PL 1250's gave me an avg. of 10.52 trigger volts.
I used a Radio Shack Micronta 22-167 digital multimeter set on auto range for DC voltage.

Came across a Soligor MZ-400AF(C) zoom flash on the Christmas Eve and wanting to test it on my G1 measured the trigger voltage to be a little over four volts. Unfortunately I didn't have reporting it here in mind so didn't take note of the exact result. It was powered by used alkalines and was set to high.

G1, 550EX, using the ST-E2: Just a couple of times, I've noticed the 550EX fire full power with the G1 in <P> mode, which nearly blinded me, my wife, and new baby, in a self portrait. Repeating exposures were fine. Perhaps dirty contacts...
And just last night, taking picture of baby and Elmo, the ST-E2 hung. You know, software hang. I'm assuming there was a continual serial data stream from the G1 -- the ST-E2 couldn't 'test' fire the 550EX, although the channel 1-4 button did work. Power cycling the G1 solved the problem.
Has anyone else seen these problems?
And what's with over exposure of the built-in flash with anything over ISO50, I have to use the flash exposure compensation each time I want faster film speed. Software -- I guess I need another firmware upgrade!

Following the article about slave flashes (http://www.botzilla.com/photo/g1strobe.html) Test pictures with digital slave flash (http://www.srelectronics.com/) DSF-1s (camera - Canon A50, dont criticize the quality - it was made in 3 minutes):


http://www.geocities.com/dmitry_shuster/sample.jpg

1 2 3 4

1. Built-in flash only.

2. Quantarray MS-1 slave flash ($30) - regular slave flash. It prodused a flash during camera's pre-flash and messed up automatic exposition - picture is underexposed.

3. DSF-1s flash ($99). It prodused a flash during camera's second (main) flash. As a result the object was illuminated by full power of both - built-in and slave flash, so the picture is overexposed.

4. MS-1 and DSF-1s slaves working together. The first one syncronized with the pre-flash, the second one - with the main flash. As a result the camera lowered the power of built-in flash and the exposition is correct.

Conclusion: If you want your camera's automatic to work correct, use TWO slave flashes (preferably with the same guide number and directed the same direction), one to syncronize with pre-flash, another to sycnronize with the main flash.

P.S. Assembling quality of DSF-1s flash is TERRIBLE. Somebody can make a good money making small pocket-size slave-flash with two capacitors - to repeat both pre-flash and main flash after the camera. The market is big enough - all pocket-size digital camera users. And - dont forget to send me a sample - as a royalty. :)

This is a great site ! I just discovered it through a camera dealer that I contacted to address my concerns about using my beloved 1970's Metz 45 CT-1 on my new G1. Botzilla's site rates the 45 CT-1 at a whooping 600V !!. You can understand my concern for my (pricey in Canada) G1. I purchased a Wein Safe-Sync HS Voltage regulator for $100.00CAN (ouch!). Being overly cautious perhaps I agonized about actually using it for 48 hours. Contacting Wein Products Inc. my camera dealer was reasured that the voltage regulator would indeed reduce the voltage to the specified 6V required by the G1. They also make regulators to reduce much higher voltage studio strobes. I, however still had trepidations so my very nice camera dealer (Lens & Shutter) offered to test my Metz 45 CT-1 brute with the Wein hot shoe voltage regulator on their G1 demo without any adverse effects. Now all I can say is "what flash problems?" ;-))))

Each time I am attempting to upload pics to my PC (W2K, 500 Mhz, 128MB, HP) using the Canon Image Browser 1.4, my Windows Explorer freezes on me - have to do a hard reset and intermittedly it starts working - usually the next day. Have reinstalled W2K and the Canon SW - same results. Any insight is greatly appreciated. Where do I get the latest version of the Canon Image Browser, may be that would help!?

Dear Kevin, I would like to post a note in the Canon talk forum discussing the G1 autofocus deficiency quoting directly from your discussion in Botzilla. What I propose to post is as follows:

I am embarrassed to admit that after owning my G1 or more than six months it is only now that I have come to realize the G1s autofocus deficiency. This is no minor problem, unlike the magenta overcast, which is easily fixed with an editing program. There is no easy fix for a camera that has a very weak autofocus system.

Rather than explain the problem in my own words, please read the exert that I have extracted from Kevin Bjorkes discussion on G1 autofocus (botzilla.com): Autofocus The G1 appears to use a contrast-based AF system. It also appears to use the entire frame to measure contrast. In other words, the contrast of pixels along the edges and in the corners are given just as much importance by the AF system as pixels near the center. This uncentered approach has serious consequences for autofocus use on real scenes. While it's fine for landscapes and may even do well for group shots, what about a head-and-shoulders portrait?

Canon's G1 manual mentions "autofocus crosshairs" on page 38, but this is simply wrong they're in the optical finder and clearly have nothing to do with the Autofocus. What's more, they may give you the impression that the AF is concentrating on the area of the crosshairs (like the "target marks" did on the previous Canon design, the Pro 70) and that's simply not true

The Pro 90 also has a "target bracket" area, which might actually do something (it's part of the EVF and LCD, not the optical finder). But both the G1 and Pro 90 manuals claim weakness to "Subjects with extremely low contrast to the surroundings." Even the A20 has AF brackets why does the G1 have this crippled system? Is it some failed prototype of the A20's AiAF ?

If Kevin is correct in his evaluation of the G1 system, and I for one have no reason to doubt him, the G1 has one major flaw that has not been picked up by the various experts who have published extensive reviews of the G1. Had I known this at the time I was ready to buy I would have bought a different camera. (Probably a Nikon 990/995) One might ask why didnt I notice this flaw earlier? I have taken many in-focus pictures with the G1 because the autofocus works adequately for many conditions considering the very generous depth of fields associated with short focal length lenses. In fact the focal length of most digital camera lenses are so short, you could get by with fixed focus for many of your routine shots. It is in those difficult shots where you most need the autofocus as for example macros or views with both foreground and distant objects in the field of view. There are workarounds using contrast targets or switching between digital zoom and manual focus (see discussion on botzilla.com ) but these shouldnt be needed with a camera of this quality.

Conclusion:

For most of us who have invested so much in the G1 it is a little too late to do much about it. We will just have to learn how to live with it and hope Canon will fix the problem on a subsequent update. I doubt if it can be fixed without some hardware changes. First Canon has to acknowledge that a problem even exists. For those considering a G1, give this some thought before you buy. There are cameras with better auto focus systems. Don T Plwase let me know if it is OK with you for me to post this message.

The Canon G1 has two autofocus methods i) the entire frame and ii) the center spot. An easier visual check when using the manual focus would be appreciated, but the spot focus eliminates most problems the camera has using contrasty backgrounds when focusing. The 'manual focus' (which I would call focus lock) method can be used to avoid some of the other problems with the auto focus method used by the camera.

I am having trouble getting my Canon G1 to work fire the Flash 420EX as a slave. I place the flash within reasonable distance (15 inches) making sure the 420 is set to slave (Set to B, then I tried A, but no luck). I set the G1 to Auto mode. I take a picture, but only the G1's flash fires. What am I missing? What are the correct steps to get: 1) Only the slave to flash 2) Both G1's flash and the 420 to flash? Thanks Lisa

Hi- Really useful, informed site - thanks. You mention that cheap, home brew circuits exist for converting high trigger voltages to safe ones. I have a Vivitar 283 I'd like to use with an Olympus c2040Z. None of the Wein safe sync configurations would work without several adapter cables which would end up costing more than a new flash. Can you point me to any circuit designs for converting my 230 V trigger voltage to <6V?

You've done a great job in analyzing the G1 and Pro90s flash capabilties. They're the most worrying points I've read about the cameras. I plan to get the Pro90 with a 420EX and would like the possibility of off-camera flash operation in the future.

Do you know of any sync speed limitation with the flash? Can fill-in be used at all speeds? I'm hoping that Canon will give you some feedback soon, and that it's something that updated can fix??

I have a little update for the strobe page. I measured the Sunpak "Digital Flash" voltage and found it to be between 6.4 and 6.6 volt with fresh Alkaline batteries. These measurements were done using a PC-synch cable and not directly on the hotshoe, using a digital multimeter and manually flashing at full power between measurements. This flash has an automatic slave and meant for use with digital cameras without hotshoe or synch-cord, but it is also usable as a regular automatic flash with GN 53. -Geert

I read your chromatic aberration page. Some dispute IR sensitivity is the problem, but I think the evidence is building up. Have you thought of using and IR/UV filter? (it's a band pass filter that cuts both UV and IR) Both B+W and Heliopan offer some of these, but they are a bit expensive to just try them. As apparently all forums about the G1 sinked into desperate newbie noise, I thought it would be better to address the question to you directly.

And BTW I like your shots, but the thumbnail page is now a mess and the resolution is a bit low (maybe your resources are limited as mine, but some feedback is always useful: we want more pixels!). Respectfully, Antonio

My original thought about CA was that it might be caused by diffraction effects within the cells of the CCD! While almost no one agrees with me on this possibility, I do think it could still be... a possibility. But if so, there should be some visible harmonics patterns, which at least I haven't been able to discern.

Update to last post. Buried way down deep in a posting at http://www.smu.edu/~rmonagha/mf/flash.html is a critical bit o' the puzzle that has generally been ignored (or worse, assumed) in most discussion groups: If a sync cable is plugged in to the Vivitar 283, the hot shoe is DISABLED. Of course, when I took my hot shoe voltage measurements sans this essential tidbit, my readings were nada, zip, zilch, etc., etc. Armed with this new insight, I disconnected the sync cord and remeasured. Lo and behold, I get 260V trigger voltage. Color me shocked!

2nd attempt.

As I am eagerly awaiting the delivery of my brand new baby G1, I discovered the various threads discussing the dangers of using older external flash units with this and other modern cameras. Not being overly anxious to fry the G1 electronics within the first few days of what I hope will be a wonderful and fulfilling relationship, I decided to follow the most excellent procedure you describe for testing the trigger voltage of an external flash, in my case, a most vintage Vivitar 283, circa late 1970s/early '80s, and actually "made in Japan."

Using a Radio Shack digital auto-ranging pocket meter, with the correct polarity probes across the flash shoe terminals, fresh alky batteries (tested at a solid 1.5VDC), and the flash fully charged in manual as well as auto modes, I could only measure about 120mV (yes, I DID say mV). If memory serves, mV is millivolts, which is a whole lot less than volts, so this has me more than a little puzzled. I even tried a backup analog volt meter (equally ancient), but it wouldn't register anything at its lowest 5VDC range, so I guess the digital was accurate. It just doesn't correlate at all with the other data mentioned at this site and others.

Any thoughts or ideas on this would be appreciated. I have emailed Vivitar tech support on this as well. It's really a nuisance that they don't change model numbers when they significantly change the product. I guess that's what the old faithful disclaimer, "specifications subject to change without notice," is all about, eh?

As for the "comment on life?" Life is a mobius strip - get over it.

I really have gotton a lot of good info from your site! I like it. I own a Pro 70 and have been watching all the posts on Phils site. I really like the Pro 70 but that Pro 90 sure looks good to me. I will buy one when I return to Texas in April. I like Canon products and if you could share your insights on the Pro 90 I would really appreciate that. I see that you pretty much like the G1. Thanks for the great informative site you have, I sure you could expand it even further and have a very popular site indeed.
