The Leica M3 is a 35 mm rangefinder camera by Ernst Leitz GmbH (now Leica Camera AG), introduced in 1954. It was a new starting point for Leitz, which until then had only produced screw-mount Leica cameras that were incremental improvements to its original Leica (Ur-Leica). The M3 introduced several features to the Leica, among them the combination of viewfinder and rangefinder in one bright window, like on the Contax II, a bayonet lens mount, and rapid film advance lever. It was the most successful model of the M series, with over 220,000 units sold by the time production of the M3 model ended in 1966.
It was succeeded by a number of later film M series cameras, including the Leica M-A film camera in 2014.
The earliest Leica M3 pre-model that was built, sold at auction in 2009 for €72,000. [1] In June 2019 a pre series model from 1952/1953 was sold for €360.000 [2] at the 34th Leitz auction in Wetzlar.
This new bayonet mount, which has not been changed in the following half century, is called the Leica M-mount. Lenses are changed faster than with a screw mount, and framelines set automatically. Non-Leitz/Leica bayonet-mount lenses can also be used (although none were produced in any quantity while the M3 was sold), and a simple adapter also allows the use of screwmount lenses (whether from Leitz or other companies).
The M3 has an exceptionally bright viewfinder when compared to any previous or subsequent model, including the modern M9. [3] The M3 has a high magnification factor of 0.92×, which is useful in critical focusing, and especially with long lenses (subsequent Leicas would use 0.85×, 0.72× or 0.58×).
It was the first Leica to combine rangefinder and viewfinder into one window. (Other cameras, such as the Contax II, already had this feature before World War II; and other companies were making screwmount bodies with combined finders.) Framelines for 50, 90 and 135mm are shown, although none for any wider lenses. However, Leica solved this problem in two different ways:
The 50 mm framelines are always visible. The viewfinder image is slightly larger. There are two ways to select the 90mm or 135mm framelines:
Viewfinder cameras do not show exactly the same image in the viewfinder and on the film, due to the distance of the viewfinder to the view axis of the lens. This parallax problem is compensated in the M3 by moving the framelines when the lens is focused. This full parallax compensation is limited to one metre; closer distances require special "Leica glasses" as described above.
The Leica IIIf and its predecessors had used a knob to advance the film. For fear of tearing the film, early M3s had a double stroke advance lever, like the Neoca 2s would. Later models (from model no 919 251) had single-stroke levers, which quickened up operation of the camera. Another type of variation is in the film pressure plate used. Early models used a glass plate to keep the film flat, whereas later models used a metal plate.
Loading of the film is done by removing the bottom plate, like on the Leica II and III series. A door flap on the rear of the camera can be raised, allowing for easier access to the film, thereby overcoming a problem associated with these earlier screw-lens-type Leicas. The film is inserted from the bottom of the camera after the user has pre-attached the leading end to the take-up spool. Special cassettes were also available.
Previous screw mount Leicas used two separate shutter speed dials for slow and fast speeds (the fast speed dial on top of the camera rotated during firing). The M3 combined slower and faster speeds and the dial does not rotate during firing. Supposedly, this reduces vibrations in the camera. Early models used a non-geometrical series of shutter speeds. On later models this became the international standard of 1s to 1/1000s.
Variants of the M3 were made for specific purposes. The Leica 24x27 was a camera with neither rangefinder nor viewfinder, made for the postal service to photograph electricity meters.
The M3 was supplemented by the M2 with a 0.85× viewfinder more suited to wide-angle lenses. The next model was the rangefinder-less M1, intended as an interface with scientific instruments or with a visoflex. With the exception of the larger Leica M5, subsequent Leica M-series cameras have a strong family resemblance to the M3.
In 2002, a miniature replica camera, the Digital Classic Camera Leica M3, was made by Minox (by then bought by Leica).
A rangefinder camera is a camera fitted with a rangefinder, typically a split-image rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus. Most varieties of rangefinder show two images of the same subject, one of which moves when a calibrated wheel is turned; when the two images coincide and fuse into one, the distance can be read off the wheel. Older, non-coupled rangefinder cameras display the focusing distance and require the photographer to transfer the value to the lens focus ring; cameras without built-in rangefinders could have an external rangefinder fitted into the accessory shoe. Earlier cameras of this type had separate viewfinder and rangefinder windows; later the rangefinder was incorporated into the viewfinder. More modern designs have rangefinders coupled to the focusing mechanism so that the lens is focused correctly when the rangefinder images fuse; compare with the focusing screen in non-autofocus SLRs.
Minolta Co., Ltd. was a Japanese manufacturer of cameras, camera accessories, photocopiers, fax machines, and laser printers. Minolta Co., Ltd., which is also known simply as Minolta, was founded in Osaka, Japan, in 1928 as Nichi-Doku Shashinki Shōten. It made the first integrated autofocus 35 mm SLR camera system. In 1931, the company adopted its final name, an acronym for "Mechanism, Instruments, Optics, and Lenses by Tashima".
Cosina Co., Ltd. is a manufacturer of high-end optical glass, optical precision equipment, cameras, video and electronic related equipment, based in Nakano, Nagano Prefecture, Japan.
Kiev is a Soviet and Ukrainian brand of photographic equipment including cameras manufactured by the Arsenal Factory in Kiev, Ukraine. The camera nameplates show the name "KIEV", with older cameras using "КИЕВ" or "КИЇВ" in Cyrillic.
Contax began as a German camera model in the Zeiss Ikon line in 1932, and later became a brand name. The early cameras were among the finest in the world, typically featuring high quality Zeiss interchangeable lenses. The final products under the Contax name were a line of 35 mm, medium format, and digital cameras engineered and manufactured by Japanese multinational Kyocera, and featuring modern Zeiss optics. In 2005, Kyocera announced that it would no longer produce Contax cameras. The rights to the brand are currently part of Carl Zeiss AG, but no Contax cameras are currently in production, and the brand is considered dormant.
The FED is a Soviet rangefinder camera, mass-produced from 1934 until around 1996, and also the name of the factory that made it.
Walter Mandler was a lens designer of Ernst Leitz Canada in Midland, Ontario. Mandler is credited with the design of more than 45 Leica lenses for the Leica rangefinder cameras and Leica SLR cameras.
The Leica M mount is a camera lens mount introduced in 1954 with the Leica M3, and a range of lenses. It has been used on all the Leica M-series cameras and certain accessories up to the current film Leica M-A and digital Leica M11 cameras.
The Leica CL is a 35mm compact rangefinder camera with interchangeable lenses in the Leica M-mount. It was developed in collaboration with Minolta who manufactured it. It first appeared in April 1973 and was released in the Japanese market in November 1973 as the Leitz Minolta CL. Both the Leica CL and Leitz Minolta CL were manufactured in a new Minolta factory in Osaka. In 2017, Leica announced a new digital mirrorless camera, again named Leica CL.
The Canon rangefinders of the late 1940s and early 1950s are Leica-compatible screw-mount cameras. Many were brought to the U.S. by servicemen who bought them while visiting Japan during the Korean War. Typically these were mounted with a 50mm Serenar lens.
The Leica III is a Barnack model rangefinder camera introduced by Leica in 1933, and produced in parallel with the Leica II series. Several models were produced over the years, with significant improvements.
The Leica M2 is a 35 mm rangefinder camera by Ernst Leitz GmbH of Wetzlar, Germany, introduced in 1957. Around 82,000 M2s were produced between 1957 and 1968. Around 1500 M2s were produced by Ernst Leitz Canada, but most of these are not marked as such on the top plate.
The Konica Hexar RF is a 35 mm rangefinder camera which was sold by Konica. It was introduced to the market on 13 October 1999. and subsequently discontinued some time before the end of 2003. The camera used the "Bayonet Konica KM-mount", a copy of the Leica M-mount, thus sharing interchangeable lenses with those designed for Leica cameras and others compatible with them. The Hexar RF has a combined rangefinder/viewfinder modeled on that of Leica cameras, a similar body shape and size - and so is similar to Leica M-mount cameras in many aspects of operation.
The Bessa family of cameras was manufactured in Japan by Cosina as a revival of the Voigtländer brand name.
The Leica M4 is a 35 mm rangefinder camera produced by Ernst Leitz GmbH.
The Leica M5 is a 35 mm camera by Leica Camera AG, introduced in 1971. It was the first Leica rangefinder camera to feature through-the-lens (TTL) metering and the last to be made entirely in Wetzlar by hand using the traditional "adjust and fit" method.
The Leica MP is a 35 mm film camera manufactured by Leica Camera AG that was introduced in 2003. It is an all-mechanical rangefinder focusing camera that follows in a long line of cameras since the Leica M3 was introduced in 1954. The camera uses the Leica M-mount, which accepts all Leica bayonet-mount lenses made since 1954. The 'MP' designation stands for "mechanical perfection."
The Leica Standard, Model E was the fourth version of the original 35 mm Leica camera to be launched from Ernst Leitz in Wetzlar, Germany. The concept was conceived by their employee Oskar Barnack in 1913. Production of the camera began in 1925 but it was not until the end of the decade that it was perfected and full-scale production was established.
The Leicaflex series of high-end single-lens reflex 35 mm format film cameras were introduced by Leitz Camera in 1964. The first camera body was paired with the new R bayonet series of lenses. Three model of the cameras were sold by Leitz; the Leicaflex Standard, the Leicaflex SL and the Leicaflex SL2.
