The Leica Summaron-M 28mm f/5.6 is a reincarnation of a classic lens design and the most compact M lens to date. The Summaron-M is modeled after the original screw mount Summaron 28mm f/5.6 lens produced at the Leitz factory in Wetzlar from 1955 to 1963. The new Leica Summaron-M 28mm f/5.6 is recreated with an M-bayonet mount, 6-bit coding and a slightly revised mechanical design but no changes to the optical design itself.
