ABSTRACT:
A camera having a flash device incorporated therein is arranged to permit use of either the incorporated internal flash unit or a detachable external flash unit. The camera is provided with a change-over switch arrangement which is operated, when the detachable flash unit is mounted on the camera, to render the incorporated flash unit, inoperative and the detachable flash unit operative. When an object to be photographed is located at a distance too far for the flash light quantity obtainable from the incorporated flash unit, the detachable flash unit which is capable of emitting a greater flash light quantity than the incorporated flash unit is used.
