The Voigtlander 25mm f/4 Color-Skopar Pancake Lens an ultra-compact wide-angle "P" type package that has the VM rangefinder lens mount. It's particularly ideal for mounting on Bessa R4M and Bessa R4A cameras, while these cameras include integrated bright frames specifically for 25mm, an accessory viewfinder is not needed. The lens can also be mounted on every camera that employs Leica M mounting.
The 25mm f/4 has exceptional close focus capability, as near as 1.5' (0.5 m). A focus lever permits you go from the minimum focusing distance all the way to infinity in fewer than ninety degrees rotation. The apertures are chosen by using a click-stop diaphragm.
Featuring an excellent scale for depth of field, the 9 bladed, circular aperture will create smooth and quite natural interpretations of defocused photos, with virtually circular light point source shapes.

M Mount Adapters
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
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.
