Asahi Pentax KM black body with SMC-Pentax-M 50mm F2 lens

The Pentax KM was one of the three original K-mount cameras introduced by Pentax as a replacement for the Spotmatic family of screw mount cameras.
The KM was basically a Spotmatic F with bayonet mount and a more modern look. From the Spotmatic F it inherited the beloved and easy to use center-the-needle metering at full open aperture. The technical specifications are almost identical with those of the Spotmatic F.
