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?
