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 Canon EOS 20D is an 8.2-megapixel semi-professional digital single-lens reflex camera, initially announced on 19 August 2004 at a recommended retail price of US$1,499. It is the successor of the EOS 10D, and was succeeded by the EOS 30D in August 2006. It accepts EF and EF-S lenses and uses an APS-C sized image sensor.
The Canon EOS 5D is a 12.7 megapixel digital single-lens reflex (DSLR) camera body produced by Canon. The EOS 5D was announced by Canon on 22 August 2005, and at the time was priced above the EOS 20D but below the EOS-1D Mark II and EOS-1Ds Mark II in Canon's EOS digital SLR series. The camera accepts EF lens mount lenses.
The Canon EOS 5 is a semi-professional autofocus, autoexposure 35 mm SLR film camera. It was sold from November 1992 onwards, and was replaced in late 1998 by the Canon EOS 3. As part of the EOS line of cameras, the 5/A2/A2e utilized Canon's EF bayonet lens mount, first introduced in 1987.
The EOS IX or EOS IX E is an APS-format single-lens reflex camera that was introduced by Canon Inc. of Japan in October 1996 as part of their EOS series SLR cameras. The other APS camera in this series is the Canon EOS IX Lite, also known as the EOS IX 7. Production ended in 2001.
In photography, through-the-lens metering refers to a feature of cameras whereby the intensity of light reflected from the scene is measured through the lens; as opposed to using a separate metering window or external hand-held light meter. In some cameras various TTL metering modes can be selected. This information can then be used to set the optimal film or image sensor exposure, it can also be used to control the amount of light emitted by a flash unit connected to the camera.
The Canon T90, introduced in 1986, was the top of the line in Canon's T series of 35 mm Single-lens reflex (SLR) cameras. It is the last professional-level manual-focus camera from Canon, and the last professional camera to use the Canon FD lens mount. Although it was overtaken by the autofocus revolution and Canon's new, incompatible EOS after only a year in production, the T90 pioneered many concepts seen in high-end Canon cameras up to the present day, particularly the user interface, industrial design, and the high level of automation.
The Olympus OM System was a line of 35mm single-lens reflex cameras, lenses and accessories sold by Olympus between 1972 and 2002. The system was introduced by Olympus in 1972. The range was designed by Yoshihisa Maitani, chief designer for Olympus, and his staff; OM stands for Olympus Maitani.
Canon's EOS flash system refers to the photographic flash equipment and automation algorithms used on Canon's film or digital EOS single-lens reflex cameras. The line was first introduced in 1987. It has gone through a number of revisions over the years, as new flash exposure metering systems have been introduced. The main light-metering technologies are known as A-TTL, E-TTL, and E-TTL II.
The EOS-1N is a 35mm single lens reflex (SLR) camera body produced by Canon. It was announced by Canon in 1994, and was the professional model in the range, superseding the original Canon EOS-1. The camera was itself superseded by the EOS-1V in 2000.
The EOS 7s / 30V / ELAN 7NE and the EOS 33V / ELAN 7N are 35 mm film single-lens reflex cameras from Canon of Japan, launched in April 2004. The 7s/30V/ELAN 7NE employ Canon's Eye Controlled Focus mechanism while the 33V/ELAN 7N do not. These cameras were the replacements for the earlier EOS 30/33 model.
The EOS 1D Mark III is a professional 10.1 megapixel digital single lens reflex camera (DSLR) camera body produced by Canon. The EOS 1D Mark III was announced on February 21, 2007 and is the successor of the Canon EOS-1D Mark II N and was first released in May 2007. In late 2009, the camera was succeeded by the Canon EOS-1D Mark IV. One of the main benefits of the new Mark III, over the previous models, was the added functionality of Live view, allowing users to take pictures while looking at an LCD screen. While it had the same outdated software as the older 1D series cameras, it had a much improved button layout, which is still used today. It also had improved wireless capabilities over the Mark II. The new WFT-E2 was much smaller than the previous WFT-E1 for the Mark II. The new transmitter could now also connect via a USB port. This allowed the optional addition of a GPS unit and wired PC connectivity.
The Canon EOS 100 is a 35 mm autofocus SLR camera introduced by Canon in 1991. It was marketed as the EOS Elan in North America. It was the second camera in the EOS range to be targeted at advanced amateur photographers, replacing the EOS 650.
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.
A pellicle mirror is an ultra-thin, ultra-lightweight semi-transparent mirror employed in the light path of an optical instrument, splitting the light beam into two separate beams, both of reduced light intensity. Splitting the beam allows its use for multiple purposes simultaneously. The thinness of the mirror practically eliminates beam or image doubling due to a non-coincident weak second reflection from the nominally non-reflecting surface, a problem with mirror-type beam splitters. The name pellicle is a diminutive of pellis, a skin or film.
The Canon EOS 500D is a 15-megapixel entry-level digital single-lens reflex camera, announced by Canon on 25 March 2009. It was released in May 2009. It is known as the EOS Kiss X3 in Japan, and as the EOS Rebel T1i in North America. It continues the Rebel line of mid-range DSLR cameras, is placed by Canon as the next model up from the EOS 450D, and has been superseded by the EOS 550D (T2i).
The Canon EOS 7D is a high-end APS-C digital single-lens reflex camera made by Canon. It was announced on 1 September 2009 with a suggested retail price of US$1,699, and was marketed as a semi-professional DSLR camera.
The Canon EOS 5D Mark III is a professional-grade 22.3 megapixel full-frame digital single-lens reflex (DSLR) camera made by Canon.
In 1989, Canon released a single lens reflex camera, the EOS-1. It utilized new technologies not found in the earlier EOS-650, in a professional level body, of which, many of its unique, distinctive characteristics are still found today in more recent versions of its series. Numerous accessories were also available to boost performance and battery life.
