Hi Shawn hope you're well and thanks for commenting. The trigger voltage on this unit is low enough to use, but to be honest compared to modern flashguns it's very basic. I have a photo project that'll I'll use it on but I'll probably buy a new one for the future. Best wishes stay safe Jon and Karen

Hi Jon. Great review. No idea if it’s safe enough (as it all goes over my head 😂). But was interested to see your process 👍

Hi Phil hope you're well and thanks for commenting, I think (hope) it'll be safe as I've done some research but I'll soon know. Modern cameras are full of delicate electronics unlike cameras of the flashgun era, which were very much more mechanical, very much like old watches. Best wishes stay safe Jon

Hey Jon, hope you both are well. Very interesting that. As far as I know the M50 is safe up to 6 volts which is lower than your test. I tried to verify this but can't find anything conclusive, even on the canon website, or forums so it could be higher. It might be ok for the odd use but I would say regular use could cause damage. However, as you know manufacturers tend to release figures like this lower than they can take, but that tolerance would be unknown. looking forward to the project you are doing! Stay Safe. Edit. - Ok found an article that states all canon EOS units have not been limited to 6volts since 2005. it doesn't state the maximum and all it says is they can take much higher. Why can't they state this??? Come on Canon! lol

Hi Steve hope you're well and thanks for commenting. I spent ages trying to find the trigger voltage for the eos line of camera but I didn't manage to find much information, so you done better than I did. Oddly enough Nikon don't seem to give out much information on trigger voltages either. I did start the photo project this afternoon, but I had to stop as we had heavy rain and hail storms, so filming in the conservatory would have sounded like being in the caravan. Tomorrow is supposed to be dry and bright. Best wishes stay safe Jon and Karen

Hi Jon, hope you are both well, love this video, I didn't realise so much went into firing a flash, good to know this stuff, I feel a little more knowledgeable after watching this. This might be a stupid question when you turned if off, it didn't really drop that many volts, does this mean that while its connected to the camera its still using power?

Hi Keith hope you're well and thanks for the kind comment. As this is a basic flashgun the camera is just acting as the switch to complete the circuit, in more modern flashguns the camera and flashgun communicate for things like TTL, sync speed, and even firmware updates. On this flashgun once turned off, the capacitor still holds the charge, but will not draw any power from the battery, it would in theory fire once but not charge up, if left the flashgun would discharge to the point where were wouldn't be enough energy to fire the flash tube. Back in the day if you left the flashgun unused for a lot period (and when bought new ) you were meant to do 4 full power flashes/charge cycles to what was known as forming the capacitor, not sure if this is a thing on new flashguns. Best wishes to all the family in Teignmouth. Stay safe Jon and Karen
