To provide a camera capable of preventing a situation that film is not fed and succeeding photographing can not be performed even when a memory unit having the same shape as silver halide film is loaded in a cartridge chamber and a rear cover is closed, and preventing handleability from getting worse even when using a camera repeatedly.

In this camera equipped with a silver halide photographing device and an electronic image pickup device, a film cartridge or a cartridge type memory 103 can be loaded in the cartridge chamber, and a main CPU 62 detects that the film cartridge or the memory 103 is loaded in the cartridge chamber. When it is detected that the film cartridge is loaded, film sensitivity is read from the film cartridge. Meanwhile, when it is detected that the memory 103 is loaded, operation concerning silver halide photography is inhibited.
