Hi Do you know any reason why it would be dangerous to connect the flash PC socket (or hotshoe middle contact with an adaptor) in EOS cameras to the remote release connector full-press pin (and ground pin)? The purpose is to trigger the second camera by the flash-on information from the first camera. This way I could use one flash with two bodies and thus get two shots at once. Naturally the first camera needs to be in manual or at least Tv mode with long enough shutter speed. My understanding is that the PC socket (or actually the semiconductor switch inside the camera body) works like a relay and should tolerate the 5V and <1mA voltage/current coming from the remote release socket. I have already shortly tested this in "lab conditions" without film and found out that it works only if I keep the second camera shutter release in half-pressed position. I used one EOS-3 and one 50E. The 50E shutter never fires unless the shutter release is half-pressed. When I trigger EOS-3 manually by shortcircuiting the ground and "full-press" pins in the remote socket it works but when I connect EOS 50E PC socket to EOS-3 remote release socket it doesn't work unless I keep the EOS-3 shutter manually half-pressed. It might be due to the (too) short flash trigger pulse from EOS 50E. I think it was around 60ms while in EOS-3 it seems to be about twice as long. Unfortunately I don't have two EOS-3s to check. Perhaps keeping the shutter release half pressed decreases the EOS-3 shutter lag? Any comments?
