Interesting you should ask. I was pondering the same question 'cause my Digital rebel has no PC socket and when I called Canon the person on the other end of the phone said that the camera can not withstand anything over 5 or 6 volts through its hot shoe connection. Well, I then checked with a Canon person at a recent workshop and he said that yes, that was the case, but that this referred only to the communication exchange pins between the camera and the dedicated Canon flash and not to the center pin ... the one we'd normally expect to use with non-Canon units and where a PC socket adapter's center pin would be connected to - so you can then plug in a PC extension cord, etc. and fire a separate flash with ... such as a higher power unit like the "potato masher" units often used near or off-camera for weddings. Or, where a non-Canon unit with just a single center pin for sync would connect on the hot shoe of the camera. The problem is that this is somewhat of a scare tactic. You don't want to be the one who by accident finds out that your camera's flash circuit was damaged by an inadvertent mis-connection as one is adding or removing the adapter from the shoe.(Best to do this with camera power off in any case). So, bottom line is thatI have used and off-brand PF adapter with Vivitar units (250 volts on trigger circuit some of them) with no ill effects to my camera. Bottom line is that I am not sure all the above text is of any use to anyone. I have not suffered an accident. A single accident, however, puts a scare in the whole group. Well, good luck! :) andy
