The Leica M can be used with a multitude of lenses far beyond those available from the current portfolio. Frequently, photographers use lenses with a “vintage” signature to achieve particular effects that are difficult to reproduce, even with the most modern digital post-processing software. The Summaron wide-angle, now more than 50 years old, is a particularly popular and compact lens that has been recreated with an M-bayonet mount, 6-bit coding, and a slightly revised design.
The Summaron-M is the smallest M-System lens. With an overall length of less than 2 cm it is incredibly discreet, making it perfect for street photography. The combination of a clearly laid out depth of field scale and long focus throw allows particularly precise pre-focusing. In addition, the enormous depth of field makes it ideal for taking advantage of hyperfocal focusing and shooting from the hip at a speed no autofocus system can match.
