Mount and adapters for the MC Rokkor-PF 55mm f/1.7
The Minolta MC Rokkor-PF 55mm f/1.7 has a native Minolta SR (MC) mount. Minolta SR is the bayonet Minolta used from 1958 to 1985 with a 43.5mm register; MC (1966) and MD (1977) are meter-coupling generations of the same mount. Every mirrorless mount has a shorter register than 43.5mm, so a plain mechanical adapter puts the lens at its design distance and infinity focus is preserved. Plain adapter ring, no mechanism needed. MC and MD lenses share the same bayonet and mount identically.
