Summaron

Summaron is a brand of camera lenses initially developed by the German company Leica. The term is particularly associated with a series of compact, high-performance lenses that were designed for use with Leica cameras, particularly in the mid-20th century. One of the most notable lenses in the Summaron line is the 35mm f/2.8 lens, which became popular for its sharpness, compact size, and optical quality.
