Leitz's first 35mm Summicron, made from 1958 to 1969 in Wetzlar and at Leitz Canada, used eight elements in six groups in an augmented double Gauss with rare earth glass; around 36,000 were built across the bayonet versions. The M3 form carries the auxiliary finder optics, the goggles that turn the M3's 50mm frame into 35mm coverage, and focuses to 0.65m rather than 0.7m. Filters are E39 and the ten blade diaphragm closes to f/16. Black paint barrels were made in far smaller numbers than chrome.
