Designed and Manufactured by Cosina

Voigtlander Heliar II 15mm f/4.5 Lens for Leica M A big development for one of their better lenses, one that put Voigtlander in the running for Leica M mount photographers. Featuring robust, high-quality traditional Japanese composition and classic styling, this Super Wide-Heliar is most likely the most obvious choice as the widest lens to mount on an Leica M8 camera and the digital rangefinder Leica M9 system. Featuring an integral 52mm UV/IR rejection filter featuring a code as "WATE" when mounted on the Leica M8, the light falloff plus cyan shifting are exceptionally well-controlled.

Manufactured by Cosina Co., Ltd (a small Japanese optics firm who also makes lenses with the Zeiss-brand), the Super Wide-Heliar stays with the identical optical formula of its beloved ancestor plus adds a precise rangefinder connection, 52mm filter threads, plus a today's Leica M mount (in place of the old Leica screw mount).

It provides an f/4.5 maximum aperture, although different than many other lenses it functions nearly as bright at f/4.5 as it does at more stopped down f/5.6 through f/11.0. There's an optional available dedicated viewfinder. Additionally it triggers 28/90mm frame lines for Leica M bodies. May 10, 2011 ✓

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.
