History
The name Summicron is derived from ''summus'', latin word for maximum and ''kronos'', the ancient Greek word for time. In the 1950s Leica bought Crown glass from Chance Brothers, an English company and used it to make the lenses. Leica designed a number of f/2 lenses before the Summicron, such as the Summar and Summitar. New coating technologies available after World War II allowed for the creation of the Summicron lens. The first Summicron was an evolved Summitar collapsible 50mm with Lanthanum glass, and was launched in 1953. Generations before approximately 1960 were produced in M39 mount ("screw mount"), then made available in M-mount (Latch-on A42), R-mount, and C-mount.Description
