This is a list of Leica Camera models.

Early models

Leica I: was first introduced to the market at the 1925 spring fair in Leipzig, based on the Ur-Leica prototype developed by Barnack in 1913 and Prototyp 1 developed in 1923. Followed by Leica Luxur and Leica Compur (a total of 60,586 of the Leica I, Luxur, and Compur models were made). Interchangeable lenses for these were introduced in 1930. Leica Standard: 1932. The first Leica camera was designed with a film-to-lens flange distance of 28.8 millimeters. Leica II: 1932. The first Leica camera with a rangefinder. Leica III: 1933. Leica incorporated slow shutter speeds on this model.

M-series rangefinder M (rangefinder) series The "M" within the nomenclature of this series of cameras comes from the first initial of "Meßsucher" (or "Messsucher"), which is the German word for "Rangefinder". M3 – 1954–1967 (Total 200,000 units manufactured) Introduced at the German photokina exhibition in 1954, the M3 was the first of the M series Leicas, a line that is still manufactured today, and featured the first Leica body with a bayonet-style mount for interchangeable lenses. In an advertisement from 1956, it was regarded as a "lifetime investment in perfect photography". The M3 has a .92 magnification finder, the highest of any M camera made. The price of this high magnification was that a 35 mm lens required "goggles" that fit in front of the view/rangefinder windows to facilitate a wider view. The M3 advanced film via a lever rather than a knob, the first M3s required two strokes to advance the film, after 1958 M3's were single stroke. Early M3s lacked a frame preview selector lever to switch between frame lines. MP – 1956–57 (Total of 402 sets were manufactured). The original MP was based on the M3 and could be fitted with a Leicavit trigger winding device. MP originally stood for "M Professional"; it was intended as a photojournalist's camera. M2 – 1958–1967 (88,000 sets were manufactured). A scaled-down and lower-cost version of the M3, the M2 had a simplified rangefinder of 0.72 magnification, allowing easier use of 35 mm lenses. The 0.72 magnification became the standard viewfinder magnification for future M cameras. The M2 lacked the self-resetting film frame counter of its predecessor. M1 – 1959–1964 (9,392 sets were manufactured). A stripped-down version of the M2 for scientific/technical use, the M1 was a viewfinder camera with no built-in rangefinder. Replaced in 1965 by the MD (with no viewfinder at all), and the MDa (based on the M4) (1967), and finally the MD-2 (based on the M4-2) (1980). M4 – 1967–1975 (50,000 sets were manufactured); 1974–75 (6,500 sets were manufactured). With added rangefinder frame lines for 35mm and 135mm lenses. Introduced the canted rewind crank (the previous Ms had rewind knobs). M5 – 1971–1975 (31,400 sets were manufactured). With added integral TTL light meter. First Leica with a light meter, a mechanical swinging-arm CDS cell positioned behind the lens. The added functionality required a redesigned, larger body compared with the traditional M3 dimensions. Certain wide-angle lenses (early 21 mm f4.0 and f3.4) could not be used in the camera without modification because of the possibility of damage to the rear element of the lens or the meter arm. For similar reasons, collapsible lenses could not be collapsed on the M5. These restrictions also held true for the Leica CL (below). With the M4, the last M-series camera to have a self-timer. CL – 1973–1976 (the compact Leica). Leitz Minolta CL introduced two lenses special to that model: the 40mm Summicron-C f2 and 90mm Elmar-C f4. Internal metering is similar to the M5 – CDS cell on a swinging stalk. The CL is also notable for being the only M-bayonet camera to have a vertically travelling shutter. Minolta later manufactured and sold an improved electronic version, the Minolta CLE with Auto Exposure, Off-The-Film TTL metering and TTL Flash metering, together with three M-Rokkor lenses, the 40mm /f2, 28mm/f2.,8 and 90mm/f4. M4-2 – 1977–1980 (17,000 sets were manufactured). First M manufactured since 1975, with stronger gears to support a motor drive. It was the first M with a hot shoe for electronic flash. No self-timer. Made in Canada. M4-P – 1980–1986. Added rangefinder frame lines for the 28mm and 75mm lenses.

M6 "Classic" – 1984–1998. A camera that first combined the M3 form factor with a modern, off-the-shutter light meter with no moving parts and LED arrows in the viewfinder. Informally referred to as the M6 "Classic" to distinguish it from the "M6 TTL" models, and to indicate its "Classic" M3 dimensions. M6J – 1994. A collector's edition of 1,640 cameras to celebrate the 40th anniversary of the Leica M System. Notable for its introduction of the 0.85 magnification finder, the first high-magnification finder since 1966, and the basis for the 0.85 cameras to follow starting in 1998. M6 0.85 – 1998. The M6 could be optionally ordered with a .85 magnification viewfinder for easier focusing with long lenses and more accurate focusing with fast lenses, such as the 50mm/f1.0 Noctilux and 75mm/f1.4 Summilux. The 28mm framelines are dropped in this model. 3,130 of these cameras were made (all black chrome), so they are among the rarer non-commemorative M6's. M6 TTL – 1998–2002. With .72 and .85 viewfinder versions. In 2000 the .58 viewfinder camera for eyeglass wearers are added to the line. Supported TTL flash. The added electronics added 2mm of height to the top plate, and the shutter dial was reversed from previous models (traditionally, turning clockwise increased shutter speed). M7 – 2002–2018. Has TTL exposure, aperture priority and manual exposure, an electronic shutter, and two mechanical speeds of 1/60 and 1/125. Comes in .58, .72, and .85 viewfinder formats, each with different brightline frame lines. Same taller top plate and counterclockwise shutter dial as the M6 TTL. Leica even produced an M7 made of solid titanium and offered it in a kit with 1 or several titanium-colored lenses. MP – 2003 – current model (as of 2020). 35 mm film. A homage to the original MP, the new MP (this time standing for "Mechanical Perfection") cosmetically resembles the original (even down to changing the rewind crank back to a knob) but is functionally closer to the M6 Classic. A notable improvement over the M6 was the modification of the rangefinder to eliminate flare. The Leicavit M is an accessory introduced with the new MP, allowing trigger wind with the right hand at speeds up to 2–2.5 frame/s. The MP is available in chrome and black paint and with viewfinders of .58, .72 and .85 magnification. M-A (typ 127) – 2014 – current model (as of 2021). A 35mm film camera with no light meter or other electronic components. It is available in silver chrome or black chrome and has a .72 magnification viewfinder as standard. M6 reissue – 2022 – current model (as of 2022). An MP variant with cosmetic changes to closely but not exactly replicate an early production M6. Features brass top and bottom plates, "Leitz" red dot logo, "ERNST LEITZ WETZLAR GERMANY" top plate engraving, M11-type abrasion-resistant black lacquer and leatherette, and "MADE IN GERMANY" embossing on the back. It is available with viewfinder magnification of 0.72. à la carte program – 2004 – June 7, 2019. Program to facilitate custom-built combinations of metal finish, leather type, viewfinder magnification, and custom engraving of some current Leica models (e.g., the M-A (typ 127) is not eligible). M8 – 2006–2009. The M8 was the first digital M introduced, featuring a 10.3-megapixel sensor. The sensor is a 1.3 crop of standard 35mm film, which gives the M8 an enlarged perspective in comparison to its predecessors. M8.2 – 2008–09. A slightly updated edition of the Leica M8, featuring a quieter shutter, sapphire glass LCD screen cover, new leather coatings, etc. Because both the M8 and M8.2 sensors lack an infrared filter, an IR-cut filter in front of the lens is required to render some synthetic material colors correctly.
