Abstract
A photographic camera with an interchangeable lens and an electrically driven function actuator for actuating some function of the camera such as the operation of the shutter. The circuit of the function actuator includes a switch responsive to the position of the interchangeable lens, so that the function actuator cannot be operated unless the interchangeable lens is fully seated or engaged in proper operating position.
