Hi there, New to the forums. I recently picked up a Polaroid 600 (non SE) and am trying to use an SB800 through PC sync. I don't have a male-male cable so I'm using a PC sync that then converts to a hotshoe which i've mounted the flash to. This works perfect with my 5D and Yashica-A but the Polaroid is being kind of wonky. When I cock the shutter and release no flash fires. Nothing actually happens. Sometimes randomly the flash will start bursting - possibly from movement of the sable a tiny bit. I also have tried a Canon 580ex. Does anyone have any idea what might be going on here?
