DKL-mount
Friedrich Deckel GmbH, also known as F.Deckel, was a German company founded by Friedrich Deckel and Christian Bruns in Munich as Bruns & Deckel in 1903. Its most famous product is the ''Compur'' line of leaf shutters used on many photographic lenses starting from 1911. Bruns and Deckel previously had worked together at C. A. Steinheil & Söhne; Bruns was an inventor responsible for developing leaf shutters while Deckel was a laboratory mechanic. Corporate history By 1910, Zeiss had acquired a 16.8% stake in F.Deckel. Zeiss also owned a significant portion of competitor (AGC), which was later renamed Prontor after its competing leaf shutter. Taking advantage of their growing knowledge of factory production methods and machinery, by about 1920 Deckel started producing "extra" machines for sale to the trade, most notably the versatile ''FP'' line of industrial milling machines. During World War II, photographic equipment production was paused and F.Deckel made fuel pumps for BMW ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flange Focal Distance
For an interchangeable lens camera, the flange focal distance (FFD) (also known as the flange-to-film distance, flange focal depth, flange back distance (FBD), flange focal length (FFL), back focus or register, depending on the usage and source) of a lens mount system is the distance from the mounting flange (the interlocking metal rings on the camera and the rear of the lens) to the film or image sensor plane. This value is different for different camera systems. The range of this distance, which will render an image clearly in focus within all focal lengths, is usually measured to a precision of hundredths of millimetres, and is not to be confused with depth of field. Lenses can be adapted from one mount (and respective FFD) to another. FFD determines whether infinity focus can be accomplished with a simple non-optical adapter. Optics to correct for distance introduce more cost and can lower image quality, so non-optical lens adapters are preferred. A simple non-optical adap ...

Kodak Retina Reflex S
The Kodak Retina Reflex is a discontinued series of four single-lens reflex cameras made by Kodak in Germany between 1957 and 1974, as part of the Kodak Retina line of 35mm film cameras. Overview The earliest Retina Reflex (Type 025, 1957) uses the convertible lens system introduced with the Kodak Retina IIc/IIIc in 1954. The successor cameras, starting with the Retina Reflex S (Type 034, 1959), use DKL-mount lenses, introduced with the Retina IIIS of 1958. The Retina Reflex brand was discontinued in 1966, then revived as the Instamatic Reflex in 1968, using the same DKL-mount lenses with the easy-loading ''Kodapak'' line of 126 film cartridges. The Instamatic Reflex was discontinued in 1974.

Kodak Retina IIIS
Retina was the brand-name of a long-running series of German-built Kodak 35mm cameras, produced from 1934 until 1969. Kodak Retina cameras were manufactured in Stuttgart-Wangen by the Kodak AG Dr. Nagel Werk which Kodak had acquired in December 1931. The Retina line included a variety of folding and non-folding models, including the Retina Reflex single lens reflex camera. Retina cameras were noted for their compact size, high quality, and low cost compared to competitors. These cameras retain a strong following today, of both photographers and collectors. Kodak AG also offered a companion line of less-expensive Retinette cameras, with similar looks and function. History August Nagel was a prolific camera designer and entrepreneur who was one of the founders of Zeiss Ikon, when he merged his company, Contessa-Nettel AG, with Zeiss and others to form that group in 1919. As well as being an owner he was an active designer of fine Zeiss cameras including miniatures. He lef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Voigtländer Vitessa
The Vitessa was a line of 35mm compact rangefinder cameras made by Voigtländer in the 1950s, equipped with leaf shutters, similar in concept to and marketed against the competing Kodak Retina cameras manufactured by Kodak. Most of the Vitessa cameras were fixed-lens models equipped with collapsable lenses for portability. One of the later Vitessa models, the Vitessa T (1956), introduced the Deckel (DKL) bayonet mount for interchangeable photographic lenses. When sold by Voigtländer, the ''Vitessa'' line was their mid-range rangefinder camera, positioned between the professional ''Prominent'' (135) and the entry-level ''Vito'' / ''Vitomatic'' / ''Vitoret''. Cameras The original Vitessa was introduced in 1950 with a fast ''Ultron'' 50 mm lens. It was joined later by a version with a ''Color-Skopar'' 50 mm ( ''Tessar''-type) lens. Contemporary marketing materials emphasized the rapid operation of the camera: by pressing the shutter release button, positioned on the ...

Rodenstock Photo Optics
Rodenstock Photo Optics traces its origins to a mechanical workshop founded in 1877 by Josef Rodenstock and his brother Michael in Würzburg, Germany. The company relocated to Munich by 1884 and became an important manufacturer of both corrective lenses for glasses and camera lenses by the early 1900s. These two lines began to diverge in the 1960s as the center of photographic lens manufacturing shifted to Japan; the ophthalmic business continued as Rodenstock GmbH while the remaining camera lens business was repositioned to serve the large format and industrial precision optics markets, then spun off in 1996 as Rodenstock Präzisionsoptik. Since then, the precision optics brand has been acquired in succession by LINOS Photonics (Göttingen, 2000), Qioptiq Group (Luxembourg, 2006), and Excelitas Technologies (2013). Photographic lenses produced by Rodenstock during and since the 20th century include the brands ''Ysarex'', ''Heligon'', ''Eurygon'', ''Rotelar'', ''Apo-Ronar'', ''Ro ...

Ground Glass
Ground glass is glass whose surface has been ground to produce a flat but rough ( matte) finish, in which the glass is in small sharp fragments. Ground glass surfaces have many applications, ranging from ornamentation on windows and table glassware to scientific uses in optics and laboratory glassware. Uses Photography In photography, a sheet of ground glass is used for the manual focusing in some still and movie cameras; the ground-glass viewer is inserted in the back of the camera, and the lens opened to its widest aperture. This projects the scene on the ground glass upside down. The photographer focuses and composes using this projected image, sometimes with the aid of a magnifying glass (or loupe). In order to see the image better, a dark cloth is used to block out light, whence came the image of the old-time photographer with his head stuck under a large black cloth. A ground glass is also used in the reflex finder of an SLR or TLR camera. In motion-picture cameras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photokina
Photokina is a trade fair held in Europe for the photographic and imaging industries. It is the world's largest such trade fair. The first Photokina was held in Cologne, Germany, in 1950, and since 1966 it has been held biennially in September at the Koelnmesse Trade Fair and Exhibition Centre in Deutz. The final Photokina under the then-current biennial cycle took place in 2018. Initially, the promoters planned to start a new annual cycle in 2019, with future shows to be held in May, but they later decided not to begin the new annual cycle until 2020. The worldwide outbreak of the Coronavirus disease 2019 and its effect on the imaging industry made Koelnmesse decide to cancel both Photokina 2020 and Photokina 2021. Many photographic and imaging companies introduce and showcase state of the art imaging products at Photokina. Similar trade shows The show has two main competitors, both of which are annual shows held in different parts of the world. The CP+ show in Yokohama, J ...
