Featuring a Big Maximum f/2.5 Aperture

Leica 75mm f/2.5 Summarit-M Manual Focus Lens

The 75mm f/2.5 Leica Summarit-M Lens is a wide lens belonging the Summarit-M stable of rangefinder lenses. Summarit-M lenses have been engineered to produce accepted optical Leica and mechanical superiority, while placed at a price range below today's M ASPH lenses. Featuring a big maximum f/2.5 aperture and by utilizing traditional and verified aspherical lens design, these lenses produce excellent quality. A consequence of these features is a very compact package

Leica lens new updated "6-bit" coding

This Leica lens features the new updated "6-bit" coding, that allows the M digital camera to optically read this information and then identify the lens being mounted. Optionally the M camera can then apply a software based "last stage" vignetting adjustment (for images captured in RAW, the lens mounted is simply recorded, with no changes made).  Read more.

All letter and number engravings will be made using the traditional "Leitz-Norm" font as originally used by Leitz Wetzlar during the 1960's, and the red button on the lens mount will be true to the original color used on lenses produced since the introduction of the M mount through the 1970's.

Includes "6-bit code" which allows the digital M8 camera to identify which lens is being used, and also to store this information in image metadata.

High quality, fast, compact and lightweight.

The 11-bladed circular aperture creates a shallow depth-of-field that brings attention to the subject and blurs the background, which is ideal for portraits and weddings.

Manufactured and marked "Made in Germany".

M Mount AdaptersLeica Four Thirds Adapter
The Leica M mount was introduced in 1954 at the same time as the Leica M3. It's been the mount of choice on every Leica M series thru the present day Leica M7 film camera and Leica M9 digital camera and Lenses.

The M Mount was also the mount used for Minolta's CLE rangefinder, on the Konica Hexar RF, on the later versions of the Voigtlander Bessa family and Lenses, the mount for the Rollei 35RF, also quite recently on the newest Zeiss Ikon Rangefinder and Lenses..

Benefits of Lens adapters is versatility, and saving money with the continued use of the preferred lenses you already own.

Drawbacks of lens adapters is the inconvenience, no electronic connection between the adapted lens and your camera body A couple of factors are necessary for a lens adapter to work properly. First, the camera body "lens registration" space or the expanse between the mount of the lens to the sensor or film surface. Two, the "throat size" of the mount or the mount diameter. An adapter flanked by the body of the camera and a lens from different brands, this registration distance of the adapted lens must be larger than the registration distance on the body; plus the lenses throat-size must be less than the throat size on the body mount. M lenses can be adapted to Canon EOS, Nikon, Micro Four Thirds, and Sony Nex Cameras.


Superb, Compact 75mm Rangefinder Camera Lens from Leica, December 17, 2007

By John Kwok (New York, NY USA)

The brand new Leica Summarit-M 75mm f2.5 is a lens certain to win ample praise from new and old users of Leica M rangefinder cameras and lenses. This relatively inexpensive (relatively inexpensive for Leica, that is) lens is a cheaper alternative to the 75mm Summicron ASPH. Much to my amazement, it is almost as fine a performer wide open at f2.5 as its older, more expensive, Summicron ASPH sibling, and definitely rivals the latter's performance at least by f5.6. Like the other Summarits, it possesses a 6 element, four group lens design consisting primarily of special glass with partial anomalous dispersion (four elements); there are two other elements comprised of high index glass. Hence it ought to be quite desirable to those who want a Leica 75mm lens, but are unwilling to pay more than $2,000 for its Summicron (f2) sibling in brand new or mint condition. I greatly enjoyed handling it at this year's Photo Plus East, and realized that it would be a fine compact traveling companion for either my Leica M4 or M6 rangefinder cameras.

How is this lens as an image maker? Judging from the sample photographs I saw at Photo Plus East, I'd say that it is truly a lens capable of spectacular results. These pictures offered more contrast, as well as the high resolution that I've come to expect from the latest generation of Leica's M-mount rangefinder lenses. If there is one slight sour gripe that I must express about this lens, then it's the regrettable fact that its lens hood must be purchased separately (This is also true for the other Summarit lenses too.). Otherwise, I think anyone who appreciates a compact Leica 75mm lens (Users of the Leica M8 should note that this lens' equivalent focal length is approximately 90mm.) will be interested in adding this Summarit lens to their kit, either as their primary 75mm lens, or as a "back-up" to their Summicron lens.
