Leitz Summicron 5cm f2 (collapsible) series 7 but can't be tightened onLeitz Summicron 5cm f2 lens for Leica M mount, just back from a full professional CLA. Focusing and diaphragm operation are excellent; glass is clean, with very light front element cleaning marks which won't affect imaging. A very early example: this lens was made in 1954, the same year the M3 was born.
