Stevie J Posted January 17 Share #1 Posted January 17 Advertisement (gone after registration) I have read somewhere that the Metz 45-CL-4 flashgun triggering voltage is 16 volts, if so, will that voltage be too high to handle by the Leica Q3 camera. I understand that most modern cameras now have a much lower triggering voltage. Please can anyone advise? I contacted Leica UK with this question, which was quickly acknowledged, yet is still to be answered by their technical department. I asked the question many months ago!

Advertisement Posted January 17 Posted January 17 Hi Stevie J, Take a look here Metz 45-CL4 Flashgun compatibility with Leica Q3 camera. I'm sure you'll find what you were looking for!
jaapv Posted January 17 Share #2 Posted January 17 I use other, even older, Metz SCA flashguns without problems on all my Leica cameras. The M series is known to be up to 600 V. I would be surprised if the Q were different. Better ask Leica Wetzlar. Link to post Share on other sites More sharing options...
Stevie J Posted January 18 Author Share #3 Posted January 18 Thanks for your opinion. I was assured by Leica UK in London, that a qualified technician would address this question, alas, I think as you do suggest, that the answer can be found in Wetzlar. I will add, that my Q3 is triggering the flash. However, until I get an official answer, I will not continue using the flash, as I am most concerned about the circuit board in the camera being potentially at risk of damage. Many thanks to you Jaapv. Link to post Share on other sites More sharing options...
ursusis Posted January 21 Share #4 Posted January 21 A slightly off topic answer. I have used a ca 1980 Braun 370 BVC flash with my Q3 with no problems at all. I worried about the voltage thing before using this old flash with the Nikon D7000 more than a decade ago. I asked my dealer about it at the time and he told me not to worry. So, I bought the small gismo seen on top of the Q3 on the attached photo and have used this combo now and then, although I later bought a Nikon SB-700 flash for the Nikons. Welcome, dear visitor!

The Braun 370 (at least 40 years young) has a trigger voltage of 21.1v (according to https://www.botzilla.com/page/strobeVolts.html) so s/b used with e.g., a Wein 'Safe Synch' to avoid camera damage. The link documents trigger voltages for many old flashguns. Personally I would not use any old flash / strobe with a modern camera unless I was certain the trigger voltage was the same or less than, compatible Leica strobes. And I certainly would not trust any dealers' opinions ref safe use of old flashguns. Some dealers are 'there today and gone tomorrow' and are not always knowledgeable about electrics / electronics.

jaapv Posted July 2 Share #6 Posted July 2 Many modern cameras including Leica handle such voltages as they have high-voltage resistant electronics in the flash circuits. If you want to make sure, give Leica CS a call. The answer probably has to come from Tokyo as the Q series is mostly Panasonic inside. The last time someone did so, it was for the M240 IIRC, it was safe up to 600V. Up until now I have not seen one report of a fried flash sync. 1 Link to post Share on other sites More sharing options...
F-train Posted July 3 Share #7 Posted July 3 (edited) Advertisement (gone after registration) Aaah the clasic Metz 45! I had a CT-4 in my early film days. Got warned that the whimpy autofocus Nikons I bought would instantly become bbq’d marsmallows if I even just connected this great flash canon. So it faded away. Would have been great to connect it to my Q’s…. Edit: Stevie, as I read it now you already fired the Metz with your Q. From what I understood circuit death would be instantaneous. So if you fired it more than once, you should be ok. Edited July 3 by F-train Info Link to post Share on other sites More sharing options...
