Hytham Saati's Aug. 28 post mentioned the chance of frying the circuitry of a digital SLR such as the 10D when using a PC cord. It got me worried, so I went on a Photo.net search--and came up with nothing. I either got a ton of irrelevant posts, or when I used the keywords "digital pc cord fry" (or frying) I came up empty...which seemed odd because they were in Hytham's post. I guess it takes awhile for Google to catch up. Grrrrrr... Anyway, I'm not quite sure what a pc cord is but I'm guessing that I own one. My Alien Bees came with a "sync" cord that plugs into the unit using a small male plug. The other end has a plug that is a male inside a sheath of metal, making it almost appear that it's both male and female. (sorry, I'm not doing very well at explaining this.) My other "connecting" cords are your basic Canon hot-shoe extension cords such as the Canon Connecting Cord 60 (2-footer) and 300 (9.8- footer). These have little plug ends with six tiny holes that match the plugs in Canon's hot shoe adapter and Canon TTL distributor. Can anyone tell me if either of these types of cords are the deadly PC cords? And if they are, what precautions I need to follow to safely use them with my 10D. Or, are they not recommended for use with a digital SLR at all? BTW...Pocket Wizards would be nice, but I'm no longer in a financial position where I can purchase additional photography equipment. Now, I've pretty much got to make due with what I have or I need to sell what won't work to fund something that will.
