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.
A camera is an optical instrument that captures images. Most cameras can capture 2D images, while some more advanced models can capture 3D images. At a basic level, most cameras consist of a sealed box, with a small hole that allows light to pass through and capture an image on a light-sensitive surface. Cameras have various mechanisms to control how light falls onto the light-sensitive surface, including lenses that focus the light and a shutter that determines the amount of time the photosensitive surface is exposed to the light.
A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. Digital cameras are now widely incorporated into mobile devices like smartphones with the same or more capabilities and features of dedicated cameras. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs.
An electronic viewfinder (EVF) is a camera viewfinder where the image captured by the lens is displayed on a small screen which the photographer can look through when composing their shot. It differs from a live preview screen in being smaller and shaded from ambient light, and may also use less power. The sensor records the view through the lens, the view is processed, and finally projected on a miniature display which is viewable through the eyepiece.
A point-and-shoot camera, also known as a compact camera and sometimes abbreviated to P&S, is a still camera designed primarily for simple operation. Most use focus free lenses or autofocus for focusing, automatic systems for setting the exposure options, and have flash units built in. They are popular for vernacular photography by people who do not consider themselves photographers but want easy-to-use cameras for snapshots of vacations, parties, reunions and other events.
A digital single-lens reflex camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.
The Canon PowerShot G is a series of digital cameras introduced by Canon in its PowerShot line in 2000. The G series cameras are Canon's flagship compact models aimed at photography enthusiasts desiring more flexibility than a point-and-shoot without the bulk of a digital single-lens reflex camera.
The Nikon F3 was Nikon's third professional single-lens reflex camera body, preceded by the F and F2. Introduced in 1980, it had manual and semi-automatic exposure control whereby the camera would select the correct shutter speed. The Nikon F3 series cameras had the most model variations of any Nikon F camera. It was also the first of numerous Nikon F-series cameras to be styled by Italian designer Giorgetto Giugiaro, and to include a red stripe on the handgrip – a feature that would later become a signature feature of many Nikon cameras.
The Olympus OM-2 is a single-lens reflex film system camera produced by Olympus of Japan.
The Nikon F5 is a high-end 35 mm film-based single-lens reflex camera body manufactured by Nikon from 1996 through 2004. It was the fifth in Nikon's professional film camera line, which began in 1959 with the Nikon F. It followed the Nikon F4 of 1988, which introduced in-body autofocus to Nikon's professional line. The F5 was in turn succeeded by the Nikon F6, as well as Nikon's parallel range of professional digital SLRs, beginning with the Nikon D1.
Lumix is Panasonic's brand of digital cameras, ranging from pocket point-and-shoot models to digital SLRs.
The Kodak EasyShare V570 was a 5-megapixel digital camera manufactured by Eastman Kodak. Announced on January 2, 2006, it was an upper-end model in the consumer price range, advertised at $400 in the United States in January 2006. It had an innovative dual lens system, combining two periscopic groups each with its own sensor: one very wide angle equivalent to a 23 mm in 135 format and a 3X zoom equivalent to a 39–117 mm, totalizing a virtual 5X zoom, with a step between 23 and 39 mm. It is the first dual lens digital camera. The model won a gold medal in the 2006 Industrial Design Excellence Awards.
The Nikon Coolpix 4300 is a digital camera that was made by Nikon. It was first released on October 1, 2002, and is no longer in production.

An included lens cap protects its Nikkor 3× optical Zoom lens, with a focal length of 8 to 24 mm, as well as an aperture of f/2.8–4.9 and shutter speed of 8–1/1,000 sec. It is capable of ISO equivalents of 100, 200, and 400.
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 EOS-1. The camera was itself superseded by the EOS-1v in 2000.
General Imaging was a manufacturer of digital cameras headquartered in Torrance, California, established in 2006 by Hiroshi "Hugh" Komiya, a former executive of Olympus Corporation.

The Kodak DC series was Kodak's pioneering consumer-grade line of digital cameras; as distinct from their much more expensive professional Kodak DCS series. Cameras in the DC series were manufactured and sold during the mid-to-late 1990s and early 2000s. Some were branded as "Digital Science". Most of these early digital cameras supported RS-232 serial port connections because USB hardware was not widely available before 1998. Some models in the DC series ran on the short lived DigitaOS, a camera operating system that allowed third party software to be installed.
The Fuji GX680 is a series of single lens reflex system cameras for medium format film produced by Fujifilm with interchangeable camera lenses and interchangeable film holders for the unusual film format 6×8 cm on 120 and 220 roll film.
