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.
In photography, shutter speed or exposure time is the length of time when the film or digital sensor inside the camera is exposed to light, also when a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time. 1⁄500 of a second will let half as much light in as 1⁄250.
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.
The Nikon F6 is a 35 mm film single-lens reflex camera body that became commercially available during 2004, and is the sixth top-of-the-line professional film camera in Nikon's line since the introduction of the Nikon F in 1959. The Nikon F6 is designed by Nikon and was manufactured at their Sendai Plant.
When setting photoflash exposures, the guide number (GN) of photoflash devices is a measure photographers can use to calculate either the required f‑stop for any given flash-to-subject distance, or the required distance for any given f‑stop. To solve for either of these two variables, one merely divides a device's guide number by the other.
The Canon A-1 is an advanced level single-lens reflex (SLR) 35 mm film camera for use with interchangeable lenses. It was manufactured by Canon Camera K. K. in Japan from April 1978 to 1985. It employs a horizontal cloth-curtain focal-plane shutter with a speed range of 30 to 1/1000 second plus bulb and flash synchronization speed of 1/60 second. It has dimensions of 92 millimetres (3.6 in) height, 141 millimetres (5.6 in) width, 48 millimetres (1.9 in) depth and 620 grams (22 oz) weight. Unlike most SLRs of the time, it was available in only one color; all black. The introductory US list price for the body plus Canon FD 50 mm f/1.4 SSC lens was $625, the camera was generally sold with a 30–40% discount.
The Canon AE-1 is a 35 mm single-lens reflex (SLR) film camera for use with interchangeable lenses. It was manufactured by Canon Camera K. K. in Japan from April 1976 to 1984. It uses an electronically controlled, electromagnet horizontal cloth focal plane shutter, with a speed range of 2 to 1/1000 second plus Bulb and flash X-sync of 1/60 second. The camera body is 87 mm tall, 141 mm wide, and 48 mm deep; it weighs 590 g. Most are black with chrome trim, but some are all black.
The Nikon FG is an interchangeable lens, 35 mm film, single-lens reflex (SLR) camera. It was manufactured by Nippon Kogaku K. K. in Japan from 1982 to 1986.
The EOS 5D is a 12.8 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.
The Canon T50, introduced in March 1983 and discontinued in December 1989, was the first in Canon's new T series of 35mm single-lens reflex cameras compatible with Canon's FD lens mount. SLR sales were falling in 1983 from the market's 1981 peak, and Canon chose to try greater automation to revive sales and remain competitive. This approach had found favor in compact cameras such as the AF35M "Autoboy" (Japan) or "Sure Shot" (US). The T50 had a power winder built in giving a continuous shooting rate of 1.4 frames per second, as well as an advanced auto-exposure mode, although it was still a manual focus camera. Unlike those compact cameras and the higher-end models in the T series, the T50 did not have power rewind, relying on a manual crank. The camera's electric systems were powered by two AA batteries in the grip, which gave enough power to shoot 75 24-exposure rolls, or 50 36-exposure rolls.
The Canon T70 was a 35mm FD-mount single-lens reflex camera introduced in April 1984 as the second in Canon's T series. The T70 started with the concepts explored in 1983's T50, took them further, and applied them to a more sophisticated camera. While the Program AE-only T50 was intended as a beginner's camera, the T70 gave the photographer a lot more control over the camera's operation while keeping the T-series philosophy of simplicity in control and operation intact.
The Canon EOS 30D is an 8.2-megapixel semi-professional digital single-lens reflex camera, initially announced on February 21, 2006. It is the successor of the Canon EOS 20D, and is succeeded by the EOS 40D. It can accept EF and EF-S lenses, and like its predecessor, it uses an APS-C sized image sensor, so it does not require the larger imaging circle necessary for 35 mm film and 'full-frame' digital cameras.
The Nikon D40 is Nikon F-mount entry-level digital SLR, announced November 16, 2006 and made until March 2009, when it was succeeded by the Nikon D3000. Compared to its predecessor, the D50, the D40 had several features removed, a few added, and a lower price: US$499.95 ESP as of November 2009 with the 18–55 mm G-II kit lens, positioning it as an entry-level model compared to the D80. The D40x has a 10-megapixel maximum resolution, up from 6 megapixels of the D40 and D50.
The Canon FP is a 35 mm SLR introduced by Canon Inc. of Japan in October 1964, using the new Canon FL lens mount. The FP and FX were virtually the same camera, but the lower priced FP did not have built in metering. At the time, many photographers preferred using a handheld meter, and others preferred the lower pricing. However, the FP was not popular making it more rare and desirable for collectors. Canon sold an external light meter with the same specifications as the built-in meter on the FX. The shutter is a horizontally traveling focal plane shutter supporting speeds between 1/1000 and 1 second in full stop increments, selected by a dial on the top plate on the photographer's right. The X-sync speed for flash is 1/55 sec.; flash support was through a PC socket on the front of the body.
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 9xi was, when new in 1992, an advanced 35 mm single-lens reflex camera design. It incorporated the world's fastest autofocus system, had a maximum shutter speed of 1/12000 of a second and a 14-zone metering system.
Most digital cameras support the ability to choose among a number of configurations, or modes, for use in various situations. Professional DSLR cameras provide several manual modes; consumer point-and-shoot cameras emphasize automatic modes; amateur prosumer cameras often have a wide variety of both manual and automatic modes.
The Canon EOS 6D is a 20.2-megapixel full-frame CMOS digital single-lens reflex camera made by Canon.
