Leica 28mm F5.6 Summaron-M Lens

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.

Original, Not Retro.
The Summaron-M is modelled on a screw mount lens produced at the Leitz factory in Wetzlar from 1955 to 1963. Its unmistakable signature is almost impossible to reproduce by digital means and makes the lens a true classic that is now reborn in a revised edition, with exactly the same optical properties. The fact that this is no simple reconstruction is obvious at first sight: the design of the Summaron-M has been refined down to the essentials, without losing any of the character of its legendary ancestor.

Recognisable at First Sight.
Through its combination of extreme depth of field, natural contrast, excellent rendition of details and visible vignetting, the lens gives images a unique character. Pictures made with the Summaron-M stand out from all others with a look reminiscent of analogue photography.

Perfect for Street Photography.
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.

An Homage to the Fine Art of Engineering.
The lens hood conjures up memories of the early days of rangefinder photography. Its design, and the meticulous manufacturing processes that went into its construction, have been recreated to match the historic ancestry of the Summaron-M. The lens hood is first machined from solid brass and then given its ultimate form by a turning and bending process. The turning process also cuts the numerous grooves into the inner surface of the lens hood.

Technical details.
The optical design of 6 elements in 4 groups arranged symmetrically around the iris of the Leica Summaron-M 28 mm f/5.6 is identical to that of its ancestor. In contrast to the legendary classic, the new model features an M-bayonet mount with 6-bit coding to enable communication between the lens and the camera.
