M Mount Adapters Leica 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.


Very sharp 135mm, November 11, 2006

By Mark W. Bohrer "Technology Writer & Documenta... (Saratoga, California)

The 135mm f/3.4 APO-Telyt is for you if you find yourself in 'urban exclusion mode' a lot to keep images simple. It's the sharpest lens available in its focal length.

It also brings up the smallest frame in any of the Leica M-cameras. For this reason, it's best used with the M3's 0.91 viewfinder magnification, or an 0.85 M6 TTL or M7. It can otherwise be hard to make out what you're trying to photograph.

A super lens for ski photography because of its light weight and small size, mine goes everywhere, unlike some of my auto-focus behemoths. A photograph of lights marching up-slope at Squaw at the end of the day produced no flare or visible chromatic aberration. It's much better than the decades-older 135mm Hektor I used to use.

It shares the reach-into-it-real look of images from the 90mm APO-Summicron-M ASPH, but if you really need the narrow view, only the longer lens will do.
