Extremely Compact Package

Leica 75mm f/2.0 APO Summicron M Aspherical Manual Focus Lens

Fast 75mm f/2.0 APO Leica Summicron M Aspherical, a quick high-performance lens in an extremely compact package. Featuring a more natural perspective when compared to a focal length of 90mm, it is perfectly apt for a number of applications including photo journalism and portraits - specifically in smaller areas. Its compact dimensions achieve not only outstanding behavior but also a viewfinder image on the Leica M that's virtually free of shadowing, providing totally uninterrupted subject viewing.

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.

Features

Optical improvements include: an aspherical surface, glass with anomalous partial dispersion and a high refractive index, a floating element including a brand new, high-precision adjusting mechanism, lens coating, and sophisticated measures to reduce internal reflection

Floating element maintains the outstanding imaging performance even at the minimum range of 2.3' (0.7 m)

Built-in lens hood can be locked in its extended position to prevent it from accidentally being pushed back in

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

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.
