From the year 1907 to the 1950s, the buildings that formed Leica factory were built on Ernst Leitz Street in Wetzlar, and remained until 1986, when the factory was moved to the city of Solms. The Wetzlar factory was located on the opposite side of the administrative building of 1957 and formed a special urban architecture; it is upstream from the slope of Kalsmunt and forms a structurally attractive graduation from the skyscrapers to the ruins of Kalsmunt Castle.

At the turn of the century, the production of optical devices expanded so much that it originated the first skyscrapers in the city of Wetzlar. The oldest part of this row of tall buildings is now hidden by a new building at the Schtzenstrae. The first plans of the architect Jean Schmidt in 1907 show a brick building on a stone base, which was covered by a sloping roof and a slate roof. However, in the same year, it was decided to use the new construction of concrete skeletons and a simpler faade design. The four-story building is divided into six groups of windows, each of which has three windows. Narrow wall patterns and lightly embedded parapets summarize the three lowest floors. The fourth floor is visually separated from the lower part of the building by a very distant cornice. On either side of the central building there was a hip roof with high ceilings. The mansard's floor expanded as production and workers also increased. Only a few years later, Leitz again demanded the construction of a tall building. After the planning of Jean Schmidt, contractor Robert Schneider built a four-story building in 1911.[3]

The basement building was made of reinforced concrete with brick stairs. Again, the original plan, which provided a horizontal structure of the building through the cornucopia, was abandoned in favor of a simpler faade design. In the ten-axis building, similar to the oldest skyscraper, the lower levels are grouped by pilasters. The space between the two skyscrapers (which originally had been provided with subsequent buildings) had to be closed by another building in the early 1930s. Once again, it was Jean Schmidt, who prepared the plans for a first seven-story skyscraper. The still existing faade drawings show the columns with arches on the ground floor and that are fitted between a long strip of windows with excessive pilasters. The general design shows a mixture of very graphic elements and remains of curved Modernist forms that recall the buildings by Joseph Maria Olbrich at Mathildenhhe of Darmstadt.

In 1936, the architect presented a completely revised plan. The plan was now made up of eight floors for Leica production. The building was built with a concrete construction modeled from the production halls of Opel in Rsselsheim, Zeiss in Jena and Wernerwerk in Berlin. It was possible to access all the floors through two stairs.

The government of the city and the district finally approved a construction of eight floors with a loggia-like ninth floor, that later was closed. Due to the urban landscape that characterized the size of the building, the planning of the district government was initially rejected because of a simple and unsatisfactory exterior design. Even so, the building was built in 1938 between the two oldest skyscrapers. In 1950, west of the skyscraper of 1911, a skyscraper of similar construction with nine floors was added.[4]

The first 35 mm film Leica prototypes were built by Oskar Barnack at Ernst Leitz Optische Werke, Wetzlar, in 1913. Some say the original Leica was intended as a compact camera for landscape photography, particularly during mountain hikes, but other sources indicate the camera was intended for test exposures with 35mm motion picture film.[5] The Leica was the first practical 35 mm camera that used standard cinema 35 mm film. The Leica transports the film horizontally, extending the frame size to 2436mm with a 2:3 aspect ratio, instead of the 1824 mm of cinema cameras, which transport the film vertically.

In 1930, the Leica I Schraubgewinde was first produced. It had an exchangeable lens system based on a 39mm diameter screw thread, often referred to as the Leica Thread Mount or LTM. In addition to the 50 mm normal lens, a 35 mm wide angle and a 135 mm telephoto lens were initially available. During the mid-1930s, a legendary soft-focus 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.[8] In 2017, a new version was produced, costing $6,495. A lens from the original series can fetch between $3,000 and $8,000, depending on condition.[9]

The Leica II was first produced in 1932, with a built in rangefinder coupled to the lens focusing mechanism. This model has a separate viewfinder (showing a reduced image) and rangefinder. In 1932, the flange to filmplane was standardised to 28.8mm, first implemented on Leica model C, and the Leica Standard the next year.[10]

The Leica III 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 November 3, 1923.

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 Hitler 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 Kristallnacht in 1938, until the borders were closed in September 1939. The extent of what came to be known as the "Leica Freedom Train" only became public after his death, well after the war.[citation needed]

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 Leica M3, with the new Leica M mount, a bayonet-like lens mount. 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 parallax 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 framelines 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 have built models based on the Leica rangefinder design. These include the Leotax, Nicca and early Canon models in Japan, the Kardon in USA, the Reid in England and the FED and Zorki in the USSR.

From 1964, Leica produced a series of single-lens reflex cameras, beginning with the Leicaflex, followed by the Leicaflex SL, the Leicaflex SL2, and then the R series from R3 to R7, made in collaboration with the Minolta Corporation. The Leica R8 was entirely designed and manufactured by Leica. The final model was the Leica R9, 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. In 2009 the R-series was discontinued, citing new camera developments that had caused a massive loss of Leica sales.[13]

Conceptually intermediate between the Rangefinder Leicas and the SLR Leicas was the Leica Visoflex System, 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 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; 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 it places Leica among the 35 mm SLR pioneers. 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.The leica M6, the top model in the company's M 35mm rangefinder camera line at the time, served as the model for this one.
