The Sigma DP2 Quattro is a large sensor digital compact camera announced by Sigma Corporation on February 13, 2014. It is the first Sigma camera to feature a new, "Quattro" branded sensor.
The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) design and development. Four Thirds refers to both the size of the image sensor (4/3") as well as the aspect ratio (4:3). The Olympus E-1 was the first Four Thirds DSLR, announced and released in 2003. In 2008, Olympus and Panasonic began publicizing the Micro Four Thirds system, a mirrorless camera system which used the same sensor size; by eliminating the reflex mirror, the Micro Four Thirds cameras were significantly smaller than the Four Thirds cameras. The first Micro Four Thirds cameras were released in 2009 and the final Four Thirds cameras were released in 2010; by that time, approximately 15 Four Thirds camera models had been released by Olympus and Panasonic in total. The Four Thirds system was quietly discontinued in 2017, six years after the final cameras were released.
The Foveon X3 sensor is a digital camera image sensor designed by Foveon, Inc., and manufactured by Dongbu Electronics. It uses an array of photosites that consist of three vertically stacked photodiodes. Each of the three stacked photodiodes has a different spectral sensitivity, allowing it to respond differently to different wavelengths. The signals from the three photodiodes are then processed as additive color data that are transformed to a standard RGB color space. In the late 1970s, a similar color sensor having three stacked photo detectors at each pixel location, with different spectral responses due to the differential absorption of light by the semiconductor, had been developed and patented by Kodak.
A digital single-lens reflex camera is a digital camera that combines the optics and mechanisms of a single-lens reflex camera with a solid-state image sensor and digitally records the images from the sensor.
Sigma Corporation is a Japanese company, manufacturing cameras, lenses, flashes and other photographic accessories. All Sigma products are produced in the company's own Aizu factory in Bandai, Fukushima, Japan. Although Sigma produces several camera models, the company is best known for producing high-quality lenses and other accessories that are compatible with the cameras produced by other companies.
The Kodak Professional DCS Pro SLR/n is a 13.5 megapixel full-frame 35mm digital SLR produced as a collaboration between Nikon Corporation and Eastman Kodak. It was an improved version of the Kodak Professional DCS Pro 14n series, and was based on a modified Nikon N80 film SLR and thus compatible with almost all Nikon F mount lenses. The camera was announced in early 2004 and became available to purchase mid-year. A monochrome variant named Kodak Professional DCS Pro SLR/n m of the camera existed as well.
Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 30.15 mm field diameter. It is therefore also equivalent in size to the Super 35 motion picture film format, which has the dimensions of 24.89 mm × 18.66 mm and Ø 31.11 mm field diameter.
The Sigma SD14 is a digital single-lens reflex camera produced by the Sigma Corporation of Japan. It is fitted with a Sigma SA mount which takes Sigma SA lenses.
In digital photography, the image sensor format is the shape and size of the image sensor.
The Sigma DP1 was a high-end compact digital camera introduced by the Sigma Corporation. It featured a 14-megapixel Foveon X3 sensor, a fixed 16.6 mm F4.0 lens, a 2.5-inch (64 mm) LCD and a pop-up flash. It was the first "compact" camera that featured an APS-C sized sensor, a feature that Sigma claimed would result in DSLR quality images from a small, pocketable camera.
Richard Billings Merrill (1949–2008), a.k.a. Dick Merrill, was an American inventor, engineer, and photographer.
The Sigma DP2 is a high-end compact digital camera introduced by the Sigma Corporation. It features a 14-megapixel Foveon X3 sensor, the same sensor used in its predecessor, the Sigma DP1 and in the Sigma SD14 DSLR, a fixed 24.2mm f/2.8 lens, a 2.5” LCD and a pop-up flash.
A mirrorless camera is a digital camera which, in contrast to DSLRs, does not use a mirror in order to ensure that the image presented to the photographer through the viewfinder is identical to that taken by the camera. They have come to replace DSLRs, which have historically dominated interchangeable lens cameras. Other terms include electronic viewfinder interchangeable lens (EVIL) cameras and compact system cameras (CSCs).
The Sigma SD15 is an updated version of Sigma SD14 DSLR produced by the Sigma Corporation of Japan and featuring the improved TRUE II image processing engine, but with the same image sensor as its predecessor. As such, the SD15 features the 4.7 MP Foveon X3 sensor. After having showcased the camera in photokina 2008 and officially introduced during PMA 2010, it finally began shipping in June 2010. It is Sigma's fourth DSLR since the SD9 from 2002.
The Sigma DP2 Merrill is a high-end compact digital camera made by Sigma Corporation. It features a 46-megapixel Foveon X3 sensor and a 30mm f/2.8 fixed lens.
The Sigma DP1s is a high-end compact digital camera introduced by the Sigma Corporation as an improvement of the Sigma DP1. It features a 14-megapixel Foveon X3 sensor, a fixed 16.6 mm F4.0 lens, a 2.5" LCD and a pop-up flash.
The Sigma DP1x is a large sensor digital compact camera announced by Sigma Corporation on February 20, 2010.
The Sigma DP2x is a large-sensor digital compact camera announced by Sigma Corporation on February 8, 2011. It features a Foveon X3 sensor.
The Sigma dp0 Quattro is a discontinued fixed-focal length APS-C digital point-and-shoot camera, announced by Sigma on February 10, 2015.
