Abstract: Disclosed is a back-focal distance control system autofocus single-lens reflex camera wherein a single-lens reflex camera body is sectioned into two blocks, one block is a fixed block while the other block is a movable block, the movable block is moved in the optical-axis direction of a lens on the basis of the fixed block, and autofocus control is conducted by adjusting a flange-focal distance of the camera.Autofocusing is attainable even by installing a manual interchangeable lens and other AF interchangeable lenses. Further, a switching operability between MF/AF operations is enhanced, and super close-range photography can be also effected. Extended further is a possible-of-AF range (from super close-range to super infinity) in combination with AF of a lens drive system. At the same time, the AF operation is conducted at a high speed with a high accuracy. Further, even when installing a lens larger in size than a standard lens, a reliability on the operation of a diaphragm mechanism is enhanced.
