All lenses for these mounts are interchangeable between older and newer Minolta manual focus 35 mm film SLR bodies.

The camera has two CdS cells attached to the top of the prism that reads in a center-weighted fashion the brightness off the focusing screen.

Instead the lens is stopped down as the aperture ring is turned (allowing depth of field preview), rather than when the shutter button is pressed.

There are also adapters for Minolta/Sony A-mount cameras, but they either do not maintain infinity focus or contain glass-elements, working as 1.2-2× tele-converter, changing the optical properties of the system and often deteriorating the image-quality.
