Leica M camera compendium

The Leica M system was launched in 1954 when the M3 was introduced. The camera was named after the German word for rangefinder ("Meßsucher") and the number of framelines that can be displayed in the viewfinder. The M3 featured several groundbreaking innovations, including the bayonet lens mount and a viewfinder with multiple, automatically changing framelines and parallax correction. The M3 stayed in production for more than a decade and inspired the refinement of the M system on an evolutionary basis.

In total, Leica sold almost 700,000 M film cameras plus an undisclosed number of digital Ms. The original M3 was by far the most popular model (and even was the camera of choice of the original James Bond), accounting for a third of all of Leica's film-rangefinder sales. While the development of the Leica M line has always maintained a purist approach to photography, the cameras were provided with additional features and functionalities over time. Exceptions to the trend towards higher convenience and performance were the M1 (no rangefinder), the MD-models for documentary work (no viewfinder), and the all mechanical MP-2003 and M-A. Additional details on the changes between camera models are contained in the listing below:

Seventeen different film rangefinders have been produced by Leica. Most M cameras were available both in black and in chrome, and some of them also in gold, olive, platin and titanium. Concerning pricing, the original MP and MP2 models are particularly rare and fetch exceptionally high auction prices as collector's items.

Leica Digital M Cameras

In 2006, Leica introduced its first digital rangefinder - the M8. Even though it represented a complete remake, the new digital rangefinder had the classic design, build and function of the M-film camera series, while utilizing a digital imaging process. The M8 had a Kodak-designed ten megapixel CCD sensor with a 1.33 format factor. Leica omitted an anti-aliasing filter in front of the sensor in order to make it possible to obtain a higher image resolution. Leica also opted for a weak IR/UV filter, which, however, turned out not to be effective enough, so that, for example, images of human-made fabrics showed a magenta cast. To avoid this image defect, the M8 (and the M8.2), had to be used with IR/UV filters in front of the lens.

Leica left the unfortunate incident of the insufficiently strong IR/UV filter behind it when introducing the M9 in 2009. The camera featured a full-frame ("Barnack-size") sensor with a 18 MP resolution, which essentially was a scaled-up version of the imaging sensor seen in the M8. The subsequently introduced M9-P, M Monochrom, and M-E all represented modifications of the M9 with selected features added or omitted.

Many observers expected an M10 as a the next evolutionary step in the system, but Leica decided to change its naming convention and simply labelled its 2013-release as "Leica M". It was the first digital rangefinder camera with a CMOS sensor, which made live view and movie recording possible. The M could also be used with R-system lenses via an adapter. In this case, an external electronic viewfinder facilitates the use of telephoto lenses with a focal length of more than 135mm.

Further Reading

Leica used to show a camera display with all its rangefinder and reflex models at its headquarters in Germany. It became known as the Leica family tree, and was subsequently maintained by the Leica Store Manchester. This family tree did not show any Limited Edition cameras, though, some of which are arguably among the most beautiful M-bodies ever made. Moreover, in case you have lost the original camera instructions, most of the Leica M Operating Manuals can be found on the web as free downloads, as can be many Leica promotional brochures. Last, but not least, there are more than hundred lenses available for the M-mount, many of which are superb both optically and mechanically.
