Stupendous Image Performance
Clear Across the Whole Field

To provide the Leica "M" system with yet greater versatility in demanding light environments, the 28mm Summicron f/2.0 Aspherical lens has become a member of the Leica Summicron fast lens line-up. By way of complex optical engineering, using special optical glass types, and the addition of a lens element that features an aspherical plane, this lens provides exceptional performance that gives the excellent performing Elmarit M 28 f/2.8 lens a run for it's money.

Now bearing in mind the fact that it's a whole stop quicker than the already fast 28 f/2.8, the designers did a remarkable job by keeping the overall size and weight of this new lens virtually identical to the old one. The lens features stupendous image performance clear across the whole field, with high resolving strength and brightness even at wide open aperture.

Leica lens new updated "6-bit" coding

Leica 28mm f/2.0 Summicron Aspherical M Manual Focus Lens

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.

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.
