Leica Serial Numbers M7

Leica I, 1927 (video) The first 35mm film Leica prototypes were built by at Ernst Leitz Optische Werke,, in 1913. Intended as a for, particularly during mountain hikes, the Leica was the first practical camera that used standard cinema. The Leica transports the film horizontally, extending the frame size to 24×36mm with a 2:3, instead of the 18×24 mm of cinema cameras which transport the film vertically. The Leica had several model iterations, and in 1923 Barnack convinced his boss, Ernst Leitz II, to make a pre-production series of 31 cameras for the factory and outside photographers to test. Though the prototypes received a mixed reception, Ernst Leitz decided in 1924 to produce the camera.

It was an immediate success when introduced at the 1925 Spring Fair as the Leica I (for Leitz camera). The focal plane has a range from 1/20 to 1/500 second, in addition to a Z for Zeit (time) position. Barnack conceived the Leica as a small camera that produced a small negative. To make large photos by enlargement, (the 'small negative, large picture' concept) requires that the camera have high quality lenses that could create well-defined negatives. Barnack tried a Zeiss on his early prototype camera, but because the Tessar was designed for the 18×24 mm cine format, it inadequately covered the Leica's 24×36mm negative.

Barnack resorted to a Leitz Mikro-Summar 1:4.5/42 mm lens for the prototype, but to achieve resolution necessary for satisfactory enlargement, the 24x36 mm format needed a lens designed specially for it. The first Leica was a 50 mm f/3.5 design based on the of 1893, adapted by Max Berek at Leitz. The lens has five elements in three groups—the third group being three cemented elements—and was initially named the Leitz Anastigmat.

Unlike other triplets, the Leitz Anastigmat has the diaphragm between the first and second elements. When the Leica was first vended, this lens was renamed the ELMAX, for E Leitz and MAX Berek. By 1925, the Leitz laboratories had produced glasses with improved optical properties, and Professor Berek designed an improved version of the ELMAX named the ELMAR that had four elements in three groups. The third group was simplified to two cemented elements, which was easier and cheaper to make. Professor Berek had two dogs, Hektor and Rex. The first of these, Hektor, gave his name to a series of Leica lenses, and the name of the second appeared in the SummaREX.

In 1930 the Leica I Schraubgewinde was first produced, with an exchangeable lens system based on a 39mm diameter screw thread, often referred to as ' Leica Thread Mount'. In addition to the 50 mm, a 35 mm and a 135 mm were initially available. During the mid-1930s, a legendary lens, the Thambar 90 mm f/2.2 was designed, and made in small numbers between 1935 and 1949, no more than 3000 units. It is now a rare collector's item. The was first produced in 1932, with a built in coupled to the lens focusing mechanism. This model has a separate viewfinder (showing a reduced image) and.

In 1932 the flange to filmplane was standardised to 28.8mm, first implemented on Leica model C, and the the next year. The added slow shutter speeds down to 1 second, and the model IIIa added the 1/1000 second shutter speed.

The IIIa is the last model made before Barnack’s death, and therefore the last model for which he was wholly responsible. Leitz continued to refine the original design through to 1957. The final version, the IIIg, includes a large viewfinder with several framelines.

These models all have a functional combination of circular dials and square windows. Early Leica cameras bear the initials D.R.P., which stands for Deutsches Reichspatent, the name for German patents before May 1945. This is probably a reference to German patent No. 384071 'Rollfilmkamera' granted to Ernst Leitz, Optische Werke in Wetzlar, on 3 November 1923. Reproduction of the Leica Prototype, 1913, 1:3,5 The company had always had progressive labor policies which encouraged the retention of skilled workers, many of whom were Jewish. Ernst Leitz II, who began managing the company in 1920, responded to the election of in 1933 by helping Jews to leave Germany, by 'assigning' hundreds (even if they were not actually employees) to overseas sales offices where they were helped to find jobs. The effort intensified after in 1938, until the borders were closed in September 1939.

The extent of what came to be known as the ' only became public after his death, well after the war. After WWII [ ] After the war, Leitz continued to produce the late versions of the Leica II and the Leica III through the 1950s. However, in 1954, Leitz introduced the, with the new, a bayonet-like.

The new camera also combined the rangefinder and viewfinder into one large, bright viewfinder with a brighter double image in the center. This system also introduced a system of compensation and a new rubberized, reliable, focal-plane shutter. Leica continues to refine this model (the latest versions being the MP and MA, both of which have frames for 28, 35, 50, 75, 90, and 135 mm lenses, which show automatically upon mounting). Post-war models bear the initials DBP, standing for Deutsches Bundespatent (Federal German Patent), instead of the DRP (Deutsches Reich patent) found on pre-war models. A number of camera companies built models based on the Leica rangefinder design. These include the, and early models in, the in, the in England and the and in the. Modern Leica M series Factory upgrade [ ] Until at least the mid-1950s, Leitz offered factory upgrades of earlier Leica cameras to the current model's specifications.

The upgraded cameras retained their original serial number. [ ] Single-lens reflex cameras [ ] From 1964, Leica produced a series of cameras, beginning with the, followed by the Leicaflex SL, the, and then the R series from R3 to R7, made in collaboration with the. The was entirely designed and manufactured by Leica. The final model was the, which could be fitted with the Digital Module back.

Leica was slow to produce an auto-exposure model, and never made a Leica R model that included auto-focusing. Official website announced (25 March 2009) that the R-series has been discontinued. The reason given was that 'new camera developments have significantly affected the sales of Leica R cameras and lenses resulting in a dramatic decrease in the number sold.

Sadly, therefore, there is no longer an economic basis on which to keep the Leica R-System in the Leica production programme.' Conceptually intermediate between the Rangefinder Leicas and the SLR Leicas was the, a mirror reflex box that attached to the lens mount of Leica rangefinders (separate versions were made for the screwmount and M series bodies) and accepted lenses made especially for the Visoflex System. Rather than using the camera’s rangefinder, focusing was accomplished via a groundglass screen.

A coupling released both mirror and shutter to make the exposure. Camera rangefinders are inherently limited in their ability to accurately focus long focal-length lenses and the mirror reflex box permitted much longer length lenses. Throughout its history, Leitz has been responsible for numerous optical innovations, such as aspherical production lenses, multicoated lenses, and rare earth lenses. The earliest Leica reflex housing was the PLOOT (Leitz's five letter code for its products), announced in 1935, along with the 200 mm f/4.5 Telyt Lens.

This date is significant because that it places Leica among the 35 mm SLR pioneers. Moreover, until the 1964 introduction of the Leicaflex, the PLOOT and Visoflex were Leica’s only SLR offerings.

A redesigned PLOOT was introduced by Leica in 1951 as the Visoflex I. This was followed by a much more compact Visoflex II in 1960 (which was the only Visoflex version available in both LTM (screwmount) and M-bayonet) and the Visoflex III with instant-return mirror in 1964.

Leica lenses for the Visoflex system included focal lengths of 65, 180 (rare), 200, 280, 400, 560, and 800mm. In addition, the optical groups of many rangefinder lenses could be removed, and attached to the Visoflex via a system of adapters. The Visoflex system was discontinued in 1984. Leica offered a wide range of accessories.

For instance, LTM (screwmount) lenses were easily usable on M cameras via an adapter. Similarly Visoflex lenses could be used on the Leicaflex and R cameras with an adapter. Furthermore, certain LTM and M rangefinder lenses featured removable optical groups that could mount via adapters on the Visoflex system, thus making them usable as rangefinder or SLR lenses for Visoflex-equipped Screwmount and M rangefinder cameras, as well as being usable on Leicaflex and R cameras. Leica also offered focusing systems, such as the Focorapid and Televit, that could replace certain lenses’ helicoid mounts for sports and natural-life telephotography. Leica’s answer to the SLR: a Leica Visoflex II on Leica IIIf Company changes [ ] In 1986, the Leitz company changed its name to Leica (LEItz CAmera), due to the fame of the Leica trade-name. At this time, Leica relocated its factory from to the nearby town of.

In 1996 Leica Camera separated from the Leica Group and became a publicly owned company. In 1998 the Leica group was divided into two independent units: and. On October 1, 2012, Leica Camera AG was delisted from the Frankfurt Stock Exchange after Lisa Germany Holding GmbH acquired the remaining minority shares stock resulting in the company being owned privately.

On November 26, 2013 Leica Camera AG announced the purchase of, Zurich, the Swiss manufacturer of view cameras. In May 2014 Leica Camera AG finished building a new factory at Am Leitz Park 1 in the new industrial part of Wetzlar and relocated back to the city where it started. First Leica The Leica is particularly associated with, especially in the mid-to-late 20th century, being used by such noted photographers as,,,,,,,,,,, and. It was also used by wartime photojournalists such as.

Leica also makes a line of cine lenses used for cinematic projects. In February 2015 their design team was awarded an Academy Scientific and Engineering Award for the optical and mechanical design of the Leica Summilux-C lenses. Role in antique trade [ ] Leica cameras, lenses, accessories and sales literature are collectibles. There are dozens of Leica books and collector’s guides, notably the three-volume Leica, an Illustrated History by James L.

Early or rare cameras and accessories can have very high prices. For instance, an anonymous buyer won a bidding battle for a rare 1923 Leica camera that sold for 2.6 million euros ($2.8 million) at an auction in Vienna. Notably, Leica cameras sporting military markings are highly valued; this started a market for refurbished Soviet copies with fake markings. Leica and Panasonic [ ].

Leica II, 1931 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 the 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 35 mm series with interchangeable lens screw mount style Leica bodies: • – 1932. The first Leica camera designed with a film-to-lensflange distance of 28.8 millimeters. The first Leica camera with a rangefinder. Leica incorporates slow shutter speeds on this model.

C (point and shoot) series [ ]. Black Chrome • – 1984–98. 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 50 mm/f1.0 Noctilux and 75 mm/f1.4 Summilux. The 28 mm 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. With a Summicron-M 28/2 ASPH Lens • M6 TTL – 1998–2002.

With.72 and.85 viewfinder versions. From 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). • 2002- current model (as of 2015).

Has TTL exposure, aperture priority and manual exposure, electronic shutter and two mechanical speeds of 1/60 and 1/125. Comes in.58,.72, and.85 viewfinder formats, each with different brightline framelines. Same taller top plate and counter-clockwise 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 like titanium colored lenses. • – 2003 – current model (as of 2015). 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 2015). 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. • A La Carte Program – as – present. Program to facilitate custom-built combinations of metal finish, leather type, viewfinder magnification, and custom engraving. Digital M (rangefinder) series [ ] • – 2006–09.

The M8 was the first digital M introduced, featuring a 10.3 megapixel sensor. The sensor is a 1.3 crop of standard 35 mm film, which gives the M8 an enlarged perspective in comparison to its predecessors. 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. Wikimedia Commons has media related to and.

• – 2009 – The first full frame digital camera in the series, introduced on September 9, 2009. • – 2011 – The full frame digital camera with a classic look, introduced in June/July 2011. • – 2012 – Announced in May 2012, scheduled for retail sale in July 2012.

A version of the M9 that shoots exclusively in monochrome. The sensor lacks both a color filtering array and an anti-aliasing filter. • (Type 220) – 2012 – Announced in September 2012, entry-level model in the Leica M full-frame digital camera range. • (Type 240) – 2012 – Announced in September 2012 • (Type 240) - 2014 - Announced in August 2014, 2GB buffer and sapphire LCD cover.

• Leica M Monochrom (Type 246) - 2015 - Announced in April 2015, 2GB buffer and sapphire LCD cover. • - 2015 - Announced in November 2015, No video and live view, aluminum top plate.

• Leica M-D (Type 262) - 2016 - Announced in April 2016, No back screen. • - 2017 - Announced in January 2017, the slimmest digital M-camera to date, identical dimensions as the M series film cameras, ISO control knob on the top plate, 0.73x magnification viewfinder. On the technical specification side, it features a 24×36 full-frame CMOS sensor made specially for M10. The sensitivity is between 100 and 50,000 ISO.

It allows shooting up to 5 frames per second. The chassis is made of magnesium alloy. It can connect to a smartphone via Wi-Fi with the M-App application. R (35 mm film SLR and DSLR) series [ ]. Leica R8 • – 1964/5 – sometimes called the Standard – built-in external light meter, clear focusing screen with centre microprism spot.

There was a great deal of pressure to introduce a Leica SLR because of the phenomenal success of the Nikon F (1959). • Leicaflex SL and SL MOT – 1968 – TTL selective-area metering, slightly taller body than its predecessor, long-lived and lovely to use. MOT model took a large and heavy motor drive.

Only about 1,000 SL MOTs were made. • /SL2 MOT – 1974 – refinement of the SL with more sensitive light meter and improved body shape. Some thought this the toughest 35 mm SLR ever built. The Leica Solms museum has an SL2 MOT on display, with Motor and 35 mm Summicron, that survived a 25,000-foot (7,600 m) fall from a Phantom II fighter jet. It was battered but in one piece, and deemed repairable by Leica. Only about 1,000 SL2 MOTs were made. The SL2 was the last of the Leicaflexes.

It reportedly cost Leitz more to manufacture than it recouped in sales, and motivated the company to collaborate with Minolta for their next series of electronic cameras. The SL2 was also the last mechanical Leica SLR for 14 years. • – the first electronic Leitz SLR – 1976 to 1980, based upon the //.

The first few were built in Germany and then production was transferred to the Leitz Portugal factory. • R4MOT/R4/R4S/R4S Mod2 – 1980–87 a new compact model based upon the /. The R4 set the design for all cameras up to and including the R7.

The R4 offered Program mode, Aperture and Shutter Priority, and Manual, with Spot and Centerweighted metering. The R4MOT differed in designation only; all R4s and up accepted motors and winders. The R4 offered The R4S and R4S Mod2 were simplified models at slightly lower prices.

• and R-E – 1987 – revised electronics (R5 had TTL flash capability), the RE was a simplified model. • – 1988–92 mechanical shutter, relied on battery power only for the built-in light meter. • Leica R6.2 – 1992 – as R6 but with refinements, including a 1/2000th shutter speed. • – 1992 – yet more advanced electronics.

• – 1996–2002 – complete redesign, this time in-house with production relocated back to Germany. All traces of Minolta gone. • – 2002-09 – refinement of the R8 with 100g less weight and a new anthracite body finish. This model and its range of lenses was discontinued in 2009. • – 10 megapixel digital back for the R8/R9, making them the first 35 mm SLR cameras able to capture to film or digitally.

This unit was discontinued in 2008. Line 6 Toneport Ux1 Driver Mac. • Leica R10 – While Leica announced in July 2009 that an R10 is forthcoming, so far one has not been released, and is unlikely given previous announcements from Leica. Leica S2 S (medium format DSLR) series [ ] • Leica S1 – The Leica S1 Pro is a scanner camera with a very high resolution (26 ) for stationary use introduced in 1996. On a 36×36 mm 2 sensor 5140×5140 pixels get scanned and optically transferred to a connected computer. The object lens adapter system was exchangeable, thus object lenses of the systems Leica R, Leica M, Hasselblad, Mamiya 4, 5×6, and all mechanic object lenses from Canon (FD), Nikon, etc. Can be used with the S1. The software for the S1 is a special version, originally developed by for high-end.

Approximately 160 cameras were built and mostly sold to museums, archives and research institutes. Later on Leica introduced the S1 Highspeed with very quick scanning and the S1 Alpha with half the resolution to the market. • – In 2008, Leica announced plans to offer an S-System – with a -made custom measuring 30×45 mm and containing 37 million pixels. This sensor has a 26% longer diagonal and 56% larger area than a DSLR sensor and outputs an approximately 5000x7500 pixel image. The is thus essentially a in a ' '-sized body.

The new 'Maestro' used in the S2 was developed by based on the and the autofocus system (Leica's first to see production) was developed in house. The S2 series body, lenses and accessories were available in 2009. A series of new Leica lenses is manufactured specifically for the S2 and Leica claims they offer unsurpassed resolution and contrast at all apertures and focusing distances, even exceeding the sensor's capabilities.

Lenses offered for the S2 include Summarit-S in normal (70 mm), wideangle (35 mm), and macro (120 mm) varieties, and Tele-Elmar (180 mm) portrait-length telephotos; these are available in versions that feature integrated multi-leaf blade shutters ('Central Shutter', or CS), in addition to the focal-plane shutter in the camera body, to enable higher flash sync speeds. Wikimedia Commons has media related to and. • – Leica announced the Leica S (Typ 006) in September 2012. It replaces the Leica S2, having a new sensor board with improved noise characteristics. • – Leica announced the Leica S (Typ 007) in September 2014. It replaces the Typ 006's CCD with a new. It offers improved noise characteristics, stills at 3.5 frames/second, and.

L-mount Cameras [ ] The was first introduced by the Leica T (Typ 701), an APS-C mirrorless camera, in April 2014. In October 2015 the second camera, Leica SL (typ 601), was introduced. The SL is a full frame mirrorless camera. The two camera mounts are mechanical and electronical 100% compatible. The only difference is a small gap around the SL mount for the SL lens sealing to cover dust and spraywater on the Leica SL. TL-System [ ] • Leica T (Typ 701) – In 2014, Leica announced Leica T (Typ 701), the first camera with a body made completely of aluminum.

Initially there were two available lenses for the camera, the Leica Summicron-T 23 mm f/2 ASPH and the Leica Vario-Elmar-T 18–56 mm f/3.5–5.6 ASPH. More lenses have been announced for 2015. • Leica TL – The is the successor of the Leica T (Typ 701).

Many Leica M lenses went through several revisions through the years. Focomat IIc • Leitz Valoy and Valoy II – manual focus, later versions of the Valoy II were grey in colour. Valoy II normally equipped with Focotar 50 mm f1:4.5 code name DOOCQ, and used with extension ring DOORX. • Leitz Focomat Ia – same as Focomat 1C, that is with autofocus, but the head does not tilt back to allow for easy insertion of negative. • Leitz Focomat Ib • Leitz Focomat Ic – sometimes fitted with Kienzle colour head. Produced with Focotar 50 mm f1:4.5 and 2nd version Focotar-2 50 mm f1:4.5.

Changes in Focotar name or focal length designation do not necessarily coincide with the optical formula. The Focotar-2 was always the same formula.

The 50 mm exists in two versions. The 1c helical accommodates lenses of various makes. Available in 'Color' version with filter drawer and lighted enlargement factor scale.

Many small design variations exist. • Leitz Focomat IIa – 35 mm–6×9 format, dual lens turret on later versions that fitted a 5 cm Elmar f1:3.5 or Focotar 1:4.5, and a 9.5 cm f1:4.5 Focotar, autofocus.

The early version has a single helical that accommodates lenses of any make. Available in 'Color' version with filter drawer and lighted enlargement factor scale. • Leitz Focomat IIc – 35 mm–6×9 formats, dual lens stage rather than turret, autofocus.

First produced with Focotar 6 cm f1:4.5 and Focotar 9.5 cm f1:4.5, later with Focotar 60 mm and V-Elmar 100 mm f1:4.5, still later with Focotar 60 mm and Focotar II 100 mm f1:5.6. 6 cm and 60 mm Focotars appear to be the same optical design. Kienzle or other colour heads sometime fitted. Only very slender enlarging lenses fit the IIc helicals. Available in 'color' version with filter drawer and lighted enlargement factor scale. • Leitz Focomat II (modified for American military), code EN-121A – extremely rare • Vincent electrical shutter (for enlarger) – extremely rare • ELCAN 52mm enlarger lens (20×–25× enlargements) – extremely rare • ELCAN 20mm enlarger lens (40×–75× enlargements) – extremely rare • Leitz/Leica Focomat V35 – mechanical autofocus – 40 mm f/2.8 Focotar lens – colour or Multigrade (variable contrast) heads.

With the 40 mm lens – wider than normal – the V35 could make 16x20 prints (16x) directly on the baseboard, and larger prints if the baseboard was reversed for floor projection.
