Abstract
In the disclosed camera system, a camera is attachable to a motor drive unit and a flash unit. In the camera, a detector produces a first signal before wind-up of the camera is completed. An interconnection terminal receives a second signal from the flash unit before charging of the flash unit is completed. A disabling arrangement prevents shutter release as long as it senses one of the first and second signals.
