Adapt M Mount Lenses to Other Brands of Cameras

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.

Auto-focusing vs Manual focusing

Although many older version manual-focus lenses may be adapted for mounting on auto-focus cameras (in particular the Canon EOS cameras, due to its shorter lens registration distance), Auto-focus lenses cannot easily adapted from one series to another, such as Minolta to Canon. Since the body of the camera cannot gain control of the lens aperture. As an example, mounting a Nikon 'G' series SLR lens (which has no aperture control) on an EOS Canon  camera, the lens can only be shot wide open, as there's no way to stop down. You'd be better off selling your existing auto-focus lenses and subsequently replacing them with equivalent lenses from the new series.  New Review May 21, 2011
