Thu, 06 Apr 06 at 04:45:16 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 Greetings Henk Henk «;ottehenk@hotmail.com» ede, CA holland

Sat, 24 Dec 05 at 05:03:49 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. best regards and a marry chrismas konstantin Konstantin «;diluo@web.de» Erfurt, th Germany

Tue, 27 Sep 05 at 04:59:47 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.

Tue, 23 Aug 05 at 21:51:31 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?

Fri, 19 Aug 05 at 05:22:02 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?

Sat, 13 Aug 05 at 12:48:21 hi ia have an alfon 787-af flash and I would like to know where I could find an ownwers manual? tanx Constantin «;constantinvpana@hotmail.com» CA USA

Tue, 02 Aug 05 at 21:09:59 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.

Thu, 28 Jul 05 at 17:30:35 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, Roberto Calviño Roberto Calviño «;rcalvino@adinet.com.uy» Montevideo, Uruguay

Wed, 27 Jul 05 at 10:05:56 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. Claudio Pagnani «;cpagnani@libero.it» Ravenna, . ITALY

Thu, 21 Jul 05 at 15:25:49 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. </rant> Thanks, Ken Bennett ken bennett «;bennettk at wfu dot edu» NC USA

Mon, 13 Jun 05 at 02:01:37 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. ***** Best regards, Doug ----- unsnip------------------------------------------------ Minsik «;minsik@4u.net» Adelaide, SA australia

Sat, 21 May 05 at 09:51:39 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.

Tue, 05 Apr 05 at 07:54:34 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.

Sun, 27 Feb 05 at 09:56:08 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! Terrence Jackson «;TJackson6925@Hotmail.com» West New York, NJ USA

Wed, 23 Feb 05 at 20:18:30 Sorry, left this out of previous post - (Wed, 23 Feb 05 at 20:08:17) Is there, anywhere, an explanation of why there is such a grab-bag of trigger voltages for these units? E.D. Wright «;ewright95503@cox.net» Eureka, CA USA

Wed, 23 Feb 05 at 20:08:17 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. E.D.

Wed, 05 Jan 05 at 12:36:47 Hi, I measured with a digital voltmeter, the strobe sync voltage on my Sunkpak 444D which I had bought over a decade ago for my Ricoh SLR. 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.

Mon, 03 Jan 05 at 17:36:14 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. Manfred Gammel «;manfred-gammel@hetnet.nl» Nuenen, NB Netherlands

Sun, 01 Aug 04 at 19:55:30 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?

Fri, 23 Jul 04 at 18:28:33 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! Dimitris Trifonopoulos Athens, Greece

Fri, 23 Jul 04 at 10:04:31 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. Adam Shahid Columbia, MO USA

Mon, 12 Jul 04 at 07:33:31 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."

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.

Fri, 18 Jun 04 at 20:01:25 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?

Wed, 26 May 04 at 12:39:36 I have recently bought an Olympus C750uz and was keen to know what constituted a 'high trigger voltage' for this camera, as the manual doesn't state any safe figure. I phoned Olympus UK tech line and was told 6v to 300v (yes 300v!!) was OK for this camera and it was ok with most studio setups. 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? Steve Fahy Yateley, Hampshire UK

Wed, 12 May 04 at 10:18:17 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. Mako Yoshikawa «;myoshik@netscape.net» Tallahassee, FL USA

Thu, 06 May 04 at 01:48:37 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 Yohanes Iwan Sugiarto «;iwax@softhome.net» Semarang, Indonesia

Sun, 15 Feb 04 at 22:58:54 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... willie willie408 «;willie408@cableone.net» Clarkston, WA USA

Tue, 20 Jan 04 at 09:31:00 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 Jim «;jstur@amigo.net» Buena Vista, CO USA

Sun, 18 Jan 04 at 22:54:55 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?

Thu, 15 Jan 04 at 18:01:49 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 -Roland Roland «;roland.koelzer@t-online.de» , LS Germany
