ABSTRACT:
A camera capable of multiple exposure photography. The camera has a lens shutter for performing a programmed exposure operation and a diaphragm-adjusting operation and a focal-plane shutter. The camera further includes a first selector means and a second selector means. The operation mode of the camera is switched between a lens shutter mode and a focal-plane shutter mode by the first selector means. In the lens shutter mode, the lens shutter is operated as a programmed shutter. In the focal-plane shutter mode, the shutter speed and the aperture are controlled by the focal-plane shutter and the lens shutter, respectively. The second selector means establishes a multiple exposure photographic mode. Also, the second selector means sets up the lens shutter mode irrespective of the setting of the first selector means.
