Tenax I
The Tenax I is a 24x24 mm fixed lens camera by Zeiss Ikon launched in 1939. The Tenax I was actually launched after the Tenax II. Like the Tenax II, it is a 24×24mm square-format camera taking over 50 exposures on a standard 135 film (35 mm), with a rapid-advance lever next to the lens. But it is a much simpler camera, with a completely different body, no rangefinder, a simple folding viewfinder on the top plate, and a ''Compur'' leaf shutter In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a photosensitive digital sensor to light in order to capture a permanent image of a scene. A shutter can also be used to allow ... to 1/300". Most of them are equipped with a Zeiss Novar 3.5 cm f/3.5 lens. A smaller number have a Carl Zeiss Jena 3.5 cm f/2.8 Tessar. Production began in 1938, and it was nearly halted in 1941. There was limited production during the rest of the war. After the war, the Ea ...

135 Film

Each image is 24×36 mm in the most common "small film" format (sometimes called "double-frame" for its relationship to the "single-frame" 35 mm movie format or full frame after the introduction of 135 sized digital sensors; confusingly, "full frame" was also used to describe the Full frame (cinematography), full gate of the movie format half the size). file:LEI0060 186 Leica I Sn.5193 1927 Originalzustand Front-2 FS-15.jpg, Leica I, 1927, the first successful camera worldwide for 35 cine film 135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film with a film gauge of loaded into a standardized type of magazine (also referred to as a cassette or cartridge) for use in 135 film cameras.

Zeiss Ikon
Zeiss ( ; ) is a German manufacturer of optical systems and optoelectronics, founded in Jena, Germany, in 1846 by optician Carl Zeiss. Together with Ernst Abbe (joined 1866) and Otto Schott (joined 1884) he laid the foundation for today's multinational company. The current company emerged from a reunification of Carl Zeiss companies in East and West Germany with a consolidation phase in the 1990s. ZEISS is active in four business segments with approximately equal revenue (Industrial Quality and Research, Medical Technology, Consumer Markets and Semiconductor Manufacturing Technology) in almost 50 countries, has 30 production sites and around 25 development sites worldwide. Carl Zeiss AG is the holding of all subsidiaries within Zeiss Group, of which Carl Zeiss Meditec AG is the only one that is traded at the stock market. Carl Zeiss AG is owned by the foundation Carl-Zeiss-Stiftung. The Zeiss Group has its headquarters in southern Germany, in the small town of Oberkochen, wit ...

Tenax II
During the 1930s, Zeiss Ikon (ZI) made a wide range of miniature cameras for the '' 35mm film'' format. Most cameras used the standard 24×36 mm frame size, like the ''Contax'', ''Nettax'' and ''Super Nettel''. However, the ability to take images in fast sequence was a popular marketing element at the time, and several fast-operating models were made. Among these were the Otto Berning's motor-driven ''Robot'' cameras as well as the ZI lever-operated ''Tenax I'' and ''Tenax II''. These have the smaller square format of 24×24 mm, enhancing faster frame advance. The Tenax II is a ''35mm'' RF-camera launched by ZI in 1938. It produces 50 square exposures on a standard length of ''35mm film''. It has a ''Compur Rapid'' shutter, situated just behind the lens, with speeds from 1 to 1/400 second. The camera is wound and the film advanced simultaneously depressing the large lever on the right-hand side of the lens. At first it was only called the ''Tenax'', but the following ...

Shutter (photography)
In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a photosensitive digital sensor to light in order to capture a permanent image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as seen in a movie projector or a signal lamp. A shutter of variable speed is used to control exposure time of the film. The shutter is constructed so that it automatically closes after a certain required time interval. The speed of the shutter is controlled either automatically by the camera based on the overall settings of the camera, manually through digital settings, or manually by a ring outside the camera on which various timings are marked. Camera shutter Camera shutters can be fitted in several positions: * Leaf shutters are usually fitted within a lens assembly (''central shutter''), or more rarely immediately behind (''behind-the-lens shutter'') or, even more rarely, in front of a lens, and s ...

Goerz (company)
C. P. Goerz was founded in 1886 by Carl Paul Goerz. Originally, it made geometrical drawing instruments for schools. From 1888 it made cameras and photographic lenses. During the World War I, First World War, Goerz's main production was for the German and Austrian military. Goerz is known primarily for Anschütz strut-folding cameras, Dagor and Tengor lenses, Tenax cameras (later continued by Zeiss Ikon) and Minicord subminiature cameras. C. P. Goerz also made a series of telescopic sights for sporting rifles that saw some use during the shortage of military sniping rifles experienced during the early stages of the trench warfare that was to characterise much of the First World War. In 1895 Goerz founded a branch in New York that was to become the C. P. Goerz American Optical Company in 1905. This company continued to operate independently in the USA until 1972. In 1908, Goerz Photochemisches Werk GmbH was founded in Zehlendorf, Berlin. This company produced roll film and film ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
