ABSTRACT:
A program type automatic exposure controller produces a selection signal in each of the film sensitivity information regions in response to information for a film sensitivity in said each of regions and changes a program constant in the aperture controller by the selection signal so that an aperture control for opening and closing a shutter may be conducted by a photometry operation of light reflected by the film surface after an aperture operation is completed.
