Contax I
The Contax I, or Original Contax, is a 35 mm rangefinder camera made between 1932 and 1936 by Zeiss Ikon. The Contax I had six identifiable variants, but fundamentally identical; every aspect was designed to outperform the Leica. For instance, the removable back was for faster loading and reloading, the bayonet lens mount was designed for rapid lens interchangeability, the long-base rangefinder allowed more accurate focusing, and the vertical metal shutter not only gave a faster maximum speed but also banished the problem of shutter blinds burning. History In 1932, Zeiss Ikon of Dresden decided to produce a competitor to the Leica II, designed to be superior in every way. The name Contax was chosen after a poll among its employees. Dr. Ing. Heinz Kuppenbender was listed On patents as the inventor of this camera. But, in fact, Dr. Emanuel Goldberg was the designer of the Contax. Goldberg continued to work on this camera design until he was forced to leave Dresden in 1933 for F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
35mm Format
135 film, more popularly referred to as 35 mm film or 35 mm, is a format of photographic film used for still photography. It is a 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. The engineering standard for this film is controlled by ISO 1007 titled '135-size film and magazine'. The term 135 was introduced by Kodak in 1934 as a designation for 35 mm film specifically for still photography, perforated with Kodak Standard perforations. It quickly grew in popularity, surpassing 120 film by the late 1960s to become the most popular photographic film size. Despite competition from formats such as 828, 126, 110, and APS, it remains the most popular film size today. The size of the 135 film frame with its aspect ratio of 1:1.50 has been adopted by many high-end digital single-lens reflex and digital mirrorless cameras, commonly referred to as "full frame". E ...

Rangefinder Camera
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 th ...

Zeiss Ikon
Carl Zeiss AG (), branded as 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 multi-national 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.

Emanuel Goldberg
Emanuel Goldberg ( he, עמנואל גולדברג; yi, עמנואל גאָלדבערג; russian: Эмануэль Гольдберг) (born: 31 August 1881; died: 13 September 1970) was an Israeli physicist and inventor. He was born in Moscow and moved first to Germany and later to Israel. He described himself as "a chemist by learning, physicist by calling, and a mechanic by birth." He contributed a wide range of theoretic and practical advances relating to light and media and was the founding head of Zeiss Ikon, the famous photographic products company in Dresden, Germany. His inventions include microdots, the Kinamo movie camera, the Contax 35 mm camera, a very early search engine, and equipment for sensitometry. Biography Goldberg was born in Moscow on 31 August 1881 (19 August 1881 in the Old Style, Julian calendar, sometimes given in error as 1 September) the son of Grigorii Ignat'evich Goldberg, a distinguished Colonel (Polkovnik) in the Tsar's military med ...

Focal-plane Shutter
In camera design, a focal-plane shutter (FPS) is a type of photographic shutter that is positioned immediately in front of the focal plane of the camera, that is, right in front of the photographic film or image sensor. Two-curtain shutters The traditional type of focal-plane shutter in 35 mm cameras, pioneered by Leitz for use in its Leica cameras, uses two shutter curtains, made of opaque rubberised fabric, that run horizontally across the film plane. For slower shutter speeds, the first curtain opens (usually) from right to left, and after the required time with the shutter open, the second curtain closes the aperture in the same direction. When the shutter is cocked again the shutter curtains are moved back to their starting positions, ready to be released. Focal-plane shutter at low speed ''Figure 1:'' The black rectangle represents the frame aperture through which the exposure is made. It is currently covered by the first shutter curtain, shown in red. The se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ludwig Bertele
Ludwig Jakob Bertele (25 December 1900 – 16 November 1985) was a German optics constructor. His developments received universal recognition and serve as a basis for considerable part of the optical designs used today. Biography Ludwig Jakob Bertele was born 25 December 1900 in Munich, to an architect's family. In 1916, Bertele was employed as the assistant of an optics designer at Rodenstock GmbH in Munich. In 1919, he moved to Dresden to work at under the supervision of August Klughardt, as a designer of optics. In the same year, Bertele would begin the development of a type of ptical scheme subsequently known as . Its basis was the optical scheme of the Ultrastigmat cinema lens, a modified Cooke triplet, which had been developed by Charles C. Minor in 1916 and produced by Gundlach Company. The main purpose of Bertele's developmental work was to increase the light-gathering power of a lens as well as diminishing optical aberration. In 1923, after four years of developmen ...
