The Leica Summicron-M 50 mm f/2 is a normal fast prime lens for 35 mm Leica M rangefinder cameras.
The lens is compatible with any Leica camera from M3 (1954) onwards. Concerning sharpness it is one of the best 50 mm cameras . Price: from $2,000 (new) to 1,100 (used) The lens came in several versions but with the same optical scheme:
1979-1994 Type 4, 195 g, Photo 5
1994-2012 Type 5, 242/335 g, built-in hood
1999 LSM (М39), 325 g, silver, minimum focusing distance - 1 m
Type 4 and Type 5's optical schemes are identical, but different from that of Type 3. The optical formula may vary from one source to another - either 6/5 or 6/4.
A small lot of lenses with a screw-threaded mount was released in 1999. In 2012 the new
APO Summicron-M 2/50 mm Asph lens was introduced.
