ABSTRACT:
A camera enables normal photographing where automatic focus adjustment and exposure operation are sequentially effected in response to a shutter release operation, and focus memory photographing where automatic focus adjustment is effected independently of exposure operation at any time prior to a shutter release operation. A movable member for operating range finding means and allowing following movement of an objective setting member and a shutter actuating member is released for movement under a spring action either by operation of a shutter release member or by operation of a focus memory operating member from a neutral position to an operating position, while the shutter actuating member is prevented from following the movable member by first and second arresting members. For normal photographing, the second arresting member is at first disabled in response to a shutter release operation and the first arresting member is disabled by the movable member immediately before the movable member completes travelling after completion of automatic focus adjustment. For focus memory photography, the first arresting member is at first disabled after completion of automatic focus adjustment, and thereafter the second arresting member is disabled in response to a shutter release operation.
