Canon EOS
Canon EOS (Electro-Optical System) is an autofocus single-lens reflex camera (SLR) and mirrorless camera series produced by Canon Inc. Introduced in 1987 with the Canon EOS 650, all EOS cameras used 35 mm film until October 1996 when the EOS IX was released using the new and short-lived APS film. In 2000, the D30 was announced, as the first digital SLR designed and produced entirely by Canon. Since 2005, all newly announced EOS cameras have used digital image sensors rather than film. The EOS line is still in production as Canon's current digital SLR (DSLR) range, and, with the 2012 introduction of the Canon EOS M, Canon's mirrorless interchangeable-lens camera (MILC) system. In 2018 the system was further extended with the introduction of the EOS R camera, Canon's first full frame mirrorless interchangeable lens system. The development project was called "EOS" (Electro Optical System). EOS is also the name of the goddess of dawn in Greek mythology, which further signifies t ...

Handel Gothic
Handel Gothic is a geometric sans-serif typeface designed in 1965 by Donald J. Handel (1936–2002), who worked for the graphic designer Saul Bass. Handel Gothic was an instant success when first released. The typeface was originally distributed in film format by FotoStar and was reissued in the 1980s by Robert Trogman. The typeface was popular in the 1980s, due to its futuristic design, and even today is used to signify the future; it has been used in the credits of both '' Star Trek: Voyager'' and '' Star Trek: Deep Space Nine'' as well as the logo for ''Close Encounters of the Third Kind''. Handel Gothic was also used for the end credits on CBS's ''The Price Is Right'' from 1972 to 1981. Handel Gothic was also used for the end credits of Sesame Street (1983-1992). The Elsner+Flake, Linotype and URW++ versions use a curved leg on uppercase R (like that of Helvetica), a horizontal tail on the uppercase Q (like that of Univers), a curved lower leg on the lowercase k, and a t ...

Contax
Contax (stylised as CONTAX in the Kyocera era) began as a German camera model in the Zeiss Ikon line in 1932, and later became a brand name. The early cameras were among the finest in the world, typically featuring high quality Zeiss interchangeable lenses. The final products under the Contax name were a line of 35 mm, medium format, and digital cameras engineered and manufactured by Japanese multinational Kyocera, and featuring modern Zeiss optics. In 2005, Kyocera announced that it would no longer produce Contax cameras. The rights to the brand are currently part of Carl Zeiss AG, but no Contax cameras are currently in production, and the brand is considered dormant. Historical overview While the firm of Ernst Leitz of Wetzlar established the 24 mm × 36 mm negative format on perforated 35 mm movie film as a viable photographic system, Zeiss Ikon of Dresden decided to produce a competitor designed to be superior in every way. The name Contax was ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canon T80
The Canon T80 is Canon's first autofocus 35mm single-lens reflex camera. It was introduced in April 1985 and discontinued in June 1986 and is part of the T series of FD mount cameras. It is not compatible with Canon's later EOS system and its autofocus EF-mount lenses. Three special lenses, designated ''AC'', were produced specifically for the camera. Other FD-mount lenses can also be used, but without autofocus capabilities. Autofocus The autofocus system in the T80 works in the same manner as the focus assist system built into the earlier AL-1. A linear CCD is used to detect contrast in the focus area. When this area has the maximum contrast, the lens is in focus. This is a similar mechanism to that used in compact digital cameras. When a manual focus lens is used, the camera provides focus assistance in exactly the same manner as the AL-1. The autofocus lenses contain a motor, and electrical contacts in the lens mount connect this motor to the camera's circuits. ...

Canon FD
The Canon FD lens mount is a physical standard for connecting a photographic lens to a 35mm single-lens reflex camera body. The standard was developed by Canon of Japan and was introduced in March 1971 with the Canon F-1 camera. It served as the Canon SLR interchangeable lens mounting system until the 1987 introduction of the Canon EOS series cameras, which use the newer EF lens mount. The FD mount lingered through the release of the 1990 Canon T60, the last camera introduced in the FD system, and the end of the Canon New F-1 product cycle in 1992. The FD mount was based upon and replaced Canon's earlier FL mount (which in turn had replaced the R mount); FD-mount cameras can use FL lenses in stop-down metering mode. Though never officially explained by Canon, others have attempted to assign a meaning to the "FD" designation. One such attempt states that the "FD" notation stands for "Focal-plane shutter with Dual linkage for diaphragm control"; in actuality, there were ...

Canon RF Mount
The Canon RF lens mount is an interchangeable- lens mount developed by Canon for its full-frame mirrorless interchangeable-lens cameras, and featured first by the EOS R, followed by the EOS RP. The RF mount was announced in September 2018. In May 2022, Canon announced APS-C EOS R cameras (the EOS R10 and EOS R7) and RF-S lenses designed for these cameras. The RF mount allows for the use of Canon EF and EF-S mount lenses using one of three Canon-made lens adapters. When an RF-S or EF-S lens is attached, however, the camera will only function as an APS-C camera, not a full-frame camera. Details Canon full-frame cameras have used the EF lens mount since 1987. In comparison with that mount, the RF mount's inner diameter is the same at 54 mm. The RF mount's flange focal distance at 20 mm is much shorter than that of the Canon EF and EF-S mounts at 44 mm. The EF-M mount has a flange focal distance of 18 mm. An EF-EOS R lens adapter enables Canon EF, EF- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canon EF Lens Mount
The EF lens mount is the standard lens mount on the Canon EOS family of SLR film and digital cameras. EF stands for "Electro-Focus": automatic focusing on EF lenses is handled by a dedicated electric motor built into the lens. Mechanically, it is a Bayonet mount, bayonet-style mount, and all communication between camera and lens takes place through electrical contacts; there are no mechanical levers or plungers. The mount was first introduced in 1987. Canon claims to have produced its 100-millionth EF-series interchangeable lens on 22 April 2014. History The EF mount replaces its predecessor, the Canon FD, FD mount. The standard autofocus lens mounting technology of the time used a motor in the camera body to drive the mechanics of the focus helicoid in the lens by using a transfer lever. The key innovation of the EF series was to use a motor inside the lens itself for focusing. This allowed for autofocusing lenses which did not require mechanical levers in the mount mechanis ...
