The Leica 90mm f/2.5 Summarit-M Lens is a wide fast telephoto 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. An ideal lens for portraits quick snapshots and photojournalism, or when you need to capture inconspicuous photos from a distance.

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.

Leica's Best in its new Summarit-M Lens Line, December 14, 2007

By John Kwok (New York, NY USA)

I had the chance to handle this fine M-mount rangefinder camera portrait (short telephoto) lens at this year's Photo Plus East and came away quite impressed with it. It focuses nearly as quickly as my APO-Summicron-M lens, but, better yet, offers a level of a performance that is as good as, if not better, than Leica's top-of-the-line fast 90mm lens at a significant savings. I saw some superb demonstration photographs taken with this lens, including a fine black and white portrait that is notable for its rich tonality (vivid blacks and whites, with very high contrast). If there is only one negative feature that I don't like about the 90mm Summarit-M lens, then it is this: it lacks a built-in lens hood (The lens hood must be purchased separately too.). Those in search of a cheaper alternative to the 90mm APO-Summicron lens won't be disappointed at all.
