Minolta SR/MC/MD manual-focus SLR mount, 1958-1980s | 35 mm SLR

Minolta SR is the mechanical foundation behind the company's MC and MD lens families. It began with the SR-2 in 1958 and matured through meter coupling, open-aperture metering, aperture-priority and program-exposure support, and compact late MD lenses.

The mount kept a long-lived manual-focus bayonet while Minolta refined the camera side around bodies such as the SR-T series, XE, XD, and X-series cameras. MC and MD labels describe coupling generations more than entirely separate mounts, so SR pages often cover lenses that collectors casually name by those later variants.

The mount's Rokkor optics are known for strong mechanical build and a wide range of distinctive primes. In this catalog, Minolta SR designs show the company's manual-focus optical style before the autofocus A-mount changed the lens-body interface completely.
