Mount and adapters for the Hexanon AR 50mm f/1.7

The Konica Hexanon AR 50mm f/1.7 has a native Konica AR mount. Konica AR is the 1965 bayonet with a 40.5mm register used by Konica Autoreflex SLRs and Hexanon lenses until 1987. Every mirrorless mount has a shorter register than 40.5mm, so a plain mechanical adapter puts the lens at its design distance and infinity focus is preserved. Plain adapter ring. The 40.5mm register is the shortest of the classic 35mm SLR mounts, so AR lenses adapt to mirrorless but cannot reach infinity on any DSLR.
