From the editor
A standard prime lens for the LEITZ minolta CL (1973). Optically and mechanically it was the same as the Leitz Wetzlar SUMMICRON-C 40/2 lens for the Leica CL. The only difference is that it uses 40.5mm filters and hood instead of Series 5.5 filters and special hood.
There was also later multi-coated version of this lens designed for the Minolta CLE (1980). It has the serial number on the lens barrel near the words "LENS MADE IN JAPAN", and not on the front name ring as the CL version.
