A camera is an optical instrument used to capture and store images or videos, either digitally via an electronic image sensor, or chemically via a light-sensitive material such as photographic film. As a pivotal technology in the fields of photography and videography, cameras have played a significant role in the progression of visual arts, media, entertainment, surveillance, and scientific research. The invention of the camera dates back to the 19th century and has since evolved with advancements in technology, leading to a vast array of types and models in the 21st century.
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.
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 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.
Bridge cameras are cameras that fill the niche between relatively simple point-and-shoot cameras and interchangeable-lens cameras such as mirrorless cameras and single-lens reflex cameras (SLRs). They are often comparable in size and weight to the smallest digital SLRs (DSLR), but lack interchangeable lenses, and almost all digital bridge cameras lack an optical viewfinder system. The phrase "bridge camera" has been in use at least since the 1980s, and continues to be used with digital cameras. The term was originally used to refer to film cameras which "bridged the gap" between point-and-shoot cameras and SLRs.
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.
Live preview is a feature that allows a digital camera's display screen to be used as a viewfinder. This provides a means of previewing framing and other exposure before taking the photograph. In most such cameras, the preview is generated by means of continuously and directly projecting the image formed by the lens onto the main image sensor. This in turn feeds the electronic screen with the live preview image. The electronic screen can be either a liquid crystal display (LCD) or an electronic viewfinder (EVF).
The EOS-1Ds Mark III is a digital SLR camera body by Canon designed for professional photographers. The Canon EOS 1Ds Mark III is successor to the EOS-1Ds Mark II and was announced in August 2007. The camera features a full-frame 21.1 megapixel CMOS sensor with 14-bit analog/digital converters for a total colour depth of 16,384 tones per pixel. It features a three-inch (76 mm) LCD screen, capable of "Live View," and dual DIGIC III processors allowing it to shoot at up to five frames per second.
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.
A mirrorless camera is a photo camera featuring a single, removable lens and a digital display. The camera does not have a reflex mirror or optical viewfinder like a digital single-lens reflex (DSLR) camera, but may have an electronic viewfinder. Many mirrorless cameras retain a mechanical shutter. Like a DSLR, a mirrorless camera accepts any of a series of interchangeable lenses compatible with its lens mount.
The Canon PowerShot S95 is a high-end 10.0-megapixel compact digital camera announced and released in 2010. It was designed as the successor to the Canon PowerShot S90 in the S series of the Canon PowerShot line of cameras.
The Fujifilm X30 is an advanced digital compact camera announced by Fujifilm on August 26, 2014. It succeeds the Fujifilm X20 whose 12 megapixel X-Trans CMOS sensor it shares. The X30 abolishes the tunnel optical viewfinder of the X20 and offers an electronic viewfinder instead. In terms of more advanced compact cameras, it occupies the middle ground between the Canon PowerShot G16 and Nikon Coolpix P7800 on the one hand, and Sony RX100 series and Canon PowerShot G1 X series on the other. In terms of Fujifilm's own product line, it is positioned as a more compact and affordable model than the Fujifilm X100S, which has a larger APS-C sized sensor that records 16 megapixels.
The Fujifilm X10 is a 2/3 sensor digital compact camera announced by Fujifilm on September 1, 2011. At the time of its release, it competed most closely with the Panasonic Lumix DMC-LX5, Olympus XZ-1, Canon PowerShot G1 X and Sony Cyber-shot DSC-RX100, and was subsequently named a 2013 iF product design award recipient.
The Canon PowerShot G1 X Mark II is a large sensor digital compact camera announced by Canon on February 12, 2014. It is the successor to the Canon PowerShot G1 X.
The Canon PowerShot G3 X is a large sensor digital bridge camera announced by Canon on June 18, 2015. It marks Canon's entry into this product category, alongside competitors such as the Panasonic Lumix DMC-FZ1000, Sony Cyber-shot RX10 and RX10 II.
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.
