Exceptionally Compact and Feather-Weight
The 28mm f/2.8 Leica Elmarit-M Aspherical Camera Lens is presently the most compact package in the Leica M-system lens line-up. This lens is virtually distortion-free over the entire focusing view from 2.3" (0.7 m) all the way to infinity and just slightly extends into the viewfinder's field of Leica M cameras.
Portrayed by its smooth, subtle likeness, the Leica Elmarit-M f/2.8 ASPH 28mm Lens is a smaller optic that is especially appropriate for street photography applications. Past its svelte stature, this wide-angle prime likewise highlights an eight-element, six-group optical configuration that contains a single aspherical element to minimize spherical aberrations and almost all distortions for sharp, clean picture quality all through the aperture and focusing ranges. Also, for instinctive use and handling, the manual focus layout lends exacting control while shooting, and its short, a little more than 1" long, profile scarcely juts into the field of M camera viewfinders for a cleaner, uncluttered point of view while forming pictures.
One aspherical component is used inside the refined optical design to diminish spherical aberrations and just about all distortions for expanded sharpness and clarity. This aspherical element likewise adds to a compact design that extends only marginally into the viewfinder of M cameras.
Brilliant f/2.8 maximum aperture is reasonable for working in an assortment of shooting conditions.
Manual focus design gives a minimum 2.3' focusing distance with a maximum 1:22 magnification ratio.
An all-metal lens hood hood is incorporated, and in addition, when the lens hood is not attached, a threaded protection ring is included. Moreover, metal lens caps are additionally included.
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). Apr 20, 2011

• Popular wide-angle choice for the Leica M-series
• Used on the digital M8 it produces the effect of a 35mm lens, which makes it ideal for reportage.
• 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 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.
Smallest, Most Compact, Leica M wide angle lens currently available, October 20, 2007
By John Kwok (New York, NY USA)
On the USA version of Leica's website, the 28mm f2.8 ASPH M-Elmarit lens is described in these glowing terms: "This new high-speed lens is the most compact of Leica M lenses. By using an aspherical element it was possible to attain top imaging performance with a weight of only 180 grams. This lens is practically distortion-free down to the close focus range of 0.7 m and only protrudes slightly into the viewfinder field of M cameras. Used on the digital M8, it produces the effect of a 35mm lens which makes it ideal for reportage. Due to its attractive price it can be particularly recommended as an introduction to the high-quality range of Leica M lenses."
It is an attractive alternative all right for those interested in acquiring a Leica M lens on a budget. Indeed, its overall appearance and physical construction owes more to the newly announced Summarit line of "budget" Leica M-mount lenses, which Leica will offer for sale starting next month. I spent some time handling and focusing it at this year's Photo Plus East, and found its barrel construction quite similar to the Zeiss Ikon rangefinder wide angle Carl Zeiss Biogon lenses (Virtually all of these are made in Japan by Cosina (Voigtlander) under strict Zeiss quality control.), falling somewhere between the popular 25 and 28 Biogons with respect to ruggedness.
But does this mean that this lens is optically better than the current 28mm Carl Zeiss Biogon or the 28mm f2 Summicron ASPH lenses? The answer is rather obvious with the 28mm Summicron, since the 28mm Summicron is the brightest fast wide angle M-mount rangefinder camera lens I've used (I own it and it has become an indispensable part of my kit.) and is tack sharp from corner to corner at virtually all apertures. In stark contrast, the 28mm f2.8 Elmarit ASPH lens isn't as sharp a lens as its more expensive, faster sibling, until f5.6, judging from the MTF charts which are posted at Leica's website (Its optical performance is similar to that of the newly announced Summarit-M lenses since they, too, perform best once the lens is stopped down to f5.6.).
As for the 28mm Carl Zeiss Biogon, it is an excellent lens in its own right, with better control for flaring - due to its Carl Zeiss T* multicoating - than the 28mm Summicron (I recently borrowed the 28mm f2.8 Biogon from the Zeiss USA office; it is almost as fine a lens as its illustrious predecessor, the Contax G Series 28mm f2.8 Biogon which I rate almost as optically superb as my 28mm Summicron. In stark comparison to the earlier 28mm Zeiss Biogon, the new Leica 28mm Elmarit lens shows some more distortion, but this shouldn't affect the quality of the pictures taken under most conditions.). So the choice ought to be easy if you are firmly committed to buying only Leica's M-mount rangefinder lenses: buy this lens, simply because it will be a fine performer for virtually every situation imaginable (The two most notable exceptions are under low light, or when a maximum aperture of f2 is required. A third one is the finest in image quality. In all three instances then you should be interested more in acquiring the 28mm Summicron.).
