ABSTRACT:
An interchangeable-lens camera is usable with a flash unit which stops the flash on the basis of the object distance and transmits a signal corresponding to a required aperture value. The camera includes a diaphragm control that responds to the light passing through the maximum aperture of the interchangeable lens and corrects for a particular maximum aperture. A selector causes the diaphragm control to respond either to the light or the signal transmitted by the flash and a switch aborts the maximum aperture connection during flash photography.
