The Canon FD 35-70mm f/4 AF lens, released in 1981, was Canon's first attempt at adding autofocus capability to their range of single-lens reflexcameras. Canon took their existing, successful Canon FD 35-70mm f/4 lens and added a box above the lens which housed a self-contained autofocus mechanism, Canon's SST (Solid State Triangulation) system, as used in the AF35ML compact camera earlier that year.
This lens provided autofocus capability when fitted to any Canon FD-mount camera—it did not require any capabilities in the camera body. The photographer simply pushed a button on the lens for it to focus automatically.
Canon used a similar autofocus system for the FD mount Canon T80 of 1985, which had a range of three lenses with integral autofocus electronics and motors. However, the T80's lenses could only autofocus when mounted on the T80. Canon abandoned further development of autofocus for the FD mount in favour of the totally new and incompatible Canon EOS system in 1987.
A single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the light receptor and the image to be captured.
Canon EOS 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 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-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.
The Minolta MAXXUM 7000 35 mm SLR camera was introduced in February 1985. It was the first camera to feature both integrated autofocus (AF) and motorised film advance, the standard configuration for later amateur and professional single lens reflex cameras.
An autofocus optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types.
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 Canon EOS 650 is a 35 mm single-lens reflex camera. It was introduced on 2 March 1987, Canon's 50th anniversary, and discontinued in February 1989. It was the first camera in Canon's new EOS series, which was designed from scratch to support autofocus lenses. The EOS system features the new EF lens mount, which uses electrical signals to communicate between the camera and the lens. Focusing and aperture control are performed by electric motors mounted in the lens body. The EF mount is still used on Canon SLRs, including digital models. Canon's previous FD mount lenses are incompatible with EOS bodies.
The Canon AL-1 was an FD mount, 35mm single-lens reflex camera introduced in March 1982. Its main feature was the "Quick Focus" focus-assist system that was aimed at those who had trouble focusing through the viewfinder—either novices, or those with poor eyesight—and was intended to head off competition from the first full-autofocus cameras from other manufacturers, such as the Pentax ME F.
The Nikon F-mount is a type of interchangeable lens mount developed by Nikon for its 35mm format single-lens reflex cameras. The F-mount was first introduced on the Nikon F camera in 1959, and features a three-lug bayonet mount with a 44mm throat and a flange to focal plane distance of 46.5mm. The company continues, with the 2020 D6 model, to use variations of the same lens mount specification for its film and digital SLR cameras.
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.
The Pentax K-mount, sometimes referred to as the "PK-mount", is a bayonet lens mount standard for mounting interchangeable photographic lenses to 35 mm single-lens reflex (SLR) cameras. It was created by Pentax in 1975, and has since been used by all Pentax 35 mm and digital SLRs and also the MILC Pentax K-01. A number of other manufacturers have also produced many K-mount lenses and K-mount cameras.
The Minolta A-mount camera system was a line of photographic equipment from Minolta introduced in 1985 with the world's first integrated autofocus system in the camera body with interchangeable lenses. The system used a lens mount called A-mount, with a flange focal distance 44.50 mm, one millimeter longer, 43.5 mm, than the previous SR mount from 1958. The new mount was wider, 49.7 mm vs. 44.97 mm, than the older SR-mount and had a longer flange focal distance making old manual lenses incompatible with the new system. Minolta bought the autofocus technology of Leica Correfot camera which was partly used on the a-mount autofocus technology. The mount is now used by Sony, who bought the SLR camera division from Konica Minolta, Konica and Minolta having merged a few years before.
The Pentax ME F was an amateur level, interchangeable lens, 35 mm film, single-lens reflex (SLR) camera. It was manufactured by Asahi Optical Co., Ltd. of Japan from November 1981 to 1984. The ME F was a heavily modified version of the Pentax ME-Super, and a member of the Pentax M-series family of SLRs. It was the first mass-produced SLR camera to come with an autofocus system.
This article is about photographic lenses for single-lens reflex film cameras (SLRs) and digital single-lens reflex cameras (DSLRs). Emphasis is on modern lenses for 35 mm film SLRs and for DSLRs with sensor sizes less than or equal to 35 mm ("full-frame").
The Minolta 9000 AF is a professional Single-lens reflex autofocus camera, introduced by Minolta in August 1985. It was both Minolta's and the world's first professional autofocus SLR. It was called Minolta Maxxum 9000 in the US and Minolta α-9000 in Japan.
The Canon Extender EF lenses are a group of teleconverter lenses made by Canon. These lenses are used between any compatible EF type lens and any of the Canon EOS line of cameras. When used with a compatible lens, they will multiply the focal length of the lens by a factor of either 1.4x or 2x, at the cost of decreasing the lens' aperture by 1 or 2 stops respectively. For example, using a 1.4x or 2x extender with the Canon EF 500mm f/4L IS USM would result in a 700mm f/5.6 or 1000mm f/8 lens.
The E-mount is a lens mount designed by Sony for their NEX and ILCE series of camcorders and mirrorless cameras. The E-mount supplements Sony's α mount, allowing the company to develop more compact imaging devices while maintaining compatibility with 35mm sensors. E-mount achieves this by:
The Canon EOS 80D is a digital single-lens reflex camera announced by Canon on February 18, 2016. It has the same body-only MSRP as the Canon EOS 70D, which it replaces. The camera can be purchased as a body-only, as kit with the 18-55mm IS STM lens, with the new 18-135mm IS USM lens or with the EF-S 18-200mm IS. As a part of the Canon EOS two-digit line, it is the successor to the EOS 70D and is the predecessor of the EOS 90D.
Nikon Z-mount is an interchangeable lens mount developed by Nikon for its mirrorless digital cameras. In late 2018, Nikon released two cameras that use this mount, the full-frame Nikon Z 7 and Nikon Z 6. In late 2019 Nikon announced their first Z-mount camera with an APS-C sensor, the Nikon Z 50. In July 2020 the entry level full-frame Z 5 was introduced. In October 2020, Nikon announced the Nikon Z 6II and Nikon Z 7II, which succeed the Z 6 and Z 7, respectively. The APS-C lineup was expanded in July of 2021, with the introduction of the retro styled Nikon Z fc, and in October 2021, Nikon unveiled the Nikon Z 9, which effectively succeeds the brand's flagship D6 DSLR. The APS-C lineup was further expanded with the Nikon Z 30, announced at the end of June 2022.
The Canon EOS R is a 30.3 megapixel full-frame mirrorless interchangeable-lens camera launched by Canon in October 2018.
