Another flashgun question.

    Didn't want to hijack Monobod's thread...

    I have an ancient flashgun that's not TTL and uses only the central trigger connection. This is a hangover from my old Praktica.

    I think it may have a bit more power than the pop-up flash on my GX-1S and would be further off axis. Is it safe to have a play on my DSLR, or is there some way it might fry the electronics?

    Quite possibly... Some older flashguns designed for purely mechanical camera can have some quite hefty trigger voltages - easily enough to fry an electronics dependent camera. There's a comprehensive list of voltages here, they relate mainly to use on EOS camera but the actual voltages are given.

    Frankly I just wouldn't risk it but if you want to then a Wein Safe-Sync is a wise purchase...

    What a fantastic list - it even had my old Practika gun listed! Thanks very much indeed.

    Apparently, the trigger voltage is 222V, so a little too much...
