ABSTRACT:
A combination of a camera device and an electronic flash device in which not only switching between the natural light mode and electronic flash mode but also the exposure control are automatically effected depending on the sensitivity of the film and the brightness of the object to be photographed. Said combination comprises means for connecting the electronic flash device to an electric power source only when the former satisfies an optimal condition of use for avoiding the loss of electric energy and does not open the shutter of the camera device when the electronic flash device does not meet the optimal conditions of use for preventing mis-operation thereof.
