Konica AR mount is a lens mount designed in 1965 for 35mm film cameras. It is a bayonet mount with three tabs, a focal flange distance of comparably short 40.5mm, a throat diameter of 47mm, and a ~60\u00b0 clockwise lock. It has “Auto” (A in AR) in its name because it was the first SLR mount to offer automatic exposure. The Auto-Reflex was the first focal-plane shutter automatic exposure 35mm SLR, and the Autoreflex T (1968.) was the first to have a TTL exposure meter.<\/p>\n\n\n\n

The lens mount was discontinued in late 1988.<\/p>\n\n\n\n
