G03B7/00—Control of exposure by setting shutters, diaphragms or filters, separately or conjointly
G03B7/08—Control effected solely on the basis of the response, to the intensity of the light received by the camera, of a built-in light-sensitive device
G03B7/12—Control effected solely on the basis of the response, to the intensity of the light received by the camera, of a built-in light-sensitive device a hand-actuated member moved from one position to another providing the energy to move the setting member, e.g. depression of shutter release button causes a stepped feeler to co-operate with the pointer of the light-sensitive device to set the diaphragm and thereafter release the shutter
