    The PC-socket on the body is coupled to the rear baffles. As there is no backwards communication from the lens to the body (that's why you have to leave your finger on the trigger as long as a long-time exposure lasts) it never knows if the lens is set to X or M. As far as I remember, the PC-socket on the body of early 500CMs is only intended for use on microscopes, bellows aso. and Hasselblad advises against its use with shuttered lenses.

    And for a reason: After opening the rear baffles, the body signals the lens to fire the shutter but doesn't know how long it will actually take untill the shutter is open and how long it will stay that way. Therefore, with long exposeure-times set on the lens synching via the body will propably work but with short exposure times where timing gets very critical (1/500th is 2 Milliseconds) and the flash may illuminate a closed shutter.
