The Four Thirds System is a standard created by Olympus and Eastman Kodak for digital single-lens reflex camera (DSLR) and mirrorless camera design and development.
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.
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.
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 Sigma SD10 is a digital single-lens reflex camera (DSLR) manufactured by the Sigma Corporation of Japan. It was announced on October 27, 2003, and is an evolution of the previous SD9 model, addressing many of the shortcomings of that camera. The Sigma SD10 cameras are unique in the digital DSLR field in using full-color sensor technology, and in that they only produce raw format images that require post-processing on a computer.
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 31.15 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 FujifilmFinePix F series is a line of compact digital cameras that was known for its low-light performance in 2005, with relatively low image noise and natural colors even at high ISO settings. With its relatively large, but moderate resolution Super CCD sensors, it concentrated on image quality, and low-light shooting without flash, which was mostly restricted to prosumer models at the time.
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.
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.
Leica X1 is a compact fixed-lens, large-sensor digital camera by Leica. The pre-production model was released to reviewers in September 2009.
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 Sigma DP3 Merrill is a high-end compact digital camera made by Sigma Corporation. It features a 46-megapixel Foveon X3 sensor and a 50mm f/2.8 fixed lens.
The Sigma DP1 Merrill is a high-end compact digital camera made by Sigma Corporation. It features a 46-megapixel Foveon X3 sensor and a 19mm f/2.8 fixed lens.
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 DP2x is a large-sensor digital compact camera announced by Sigma Corporation on February 8, 2011. It features a Foveon X3 sensor.
The Sony RX is the name of a range of fixed lens compact point-and-shoot digital cameras created by Sony in 2012. All cameras are equipped with Carl Zeiss lenses.
The Leica Q2 is a full-frame fixed-lens camera introduced in 2019.
