The Minolta M-Rokkor 40 mm f/ 2.0 is a standard fast prime lens with a proprietary multi-coating for 35 mm rangefinder Leica M cameras.
The Minolta M-Rokkor 40mm f/2.0 was developed by Leitz and was manufactured by Minolta in Japan since 1973.
The analogous Leica Summicron-C 40mm f/2.0lens was manufactured by Leitz in Germany.
The lenses differ in filter diameter only (M-Rokkor - 40,5 mm; Summicron-C - Series - 55 mm).
There exists an opinion that the focal length of the lens is not 40 mm, but 37 mm, i.e. it almost fits into a 35 mm frame. It was used as a kit lens for Minolta CL cameras (Leica CL analog).
There is a later multicoated version of the Minolta M-Rokkor 40 mm f/ 2.0 designed for the Minolta CLE camera. In the photo you can see the M-Rokkor 40mm f/2.0, CLE version. The serial number of a CL lens is placed on the front part near the "Minolta M-Rokkor" designation; CLE lenses have the serial number placed in the rear part near the "Lens made in Japan" designation.
