Kodak DCS

The Kodak Digital Camera System is a series of digital single-lens reflex cameras and digital camera backs that were released by Kodak in the 1990s and 2000s, and discontinued in 2005. They were all based on existing 35mm film SLRs from Nikon, Canon and Sigma. The range included the original Kodak DCS, the very first commercially available digital SLR.

In 1975 Kodak engineer Steven Sasson invented the first digital still camera, which used a Fairchild 100 x 100 pixel CCD. By 1986 Kodak had developed a sensor with 1.4 million pixels.

A number of other inventions were made to increase usability, including improvements in sensor technology, the first Raw image format DCR, and usable host software. The original Kodak DCS was launched in 1991, and was based on a stock Nikon F3 SLR with digital components. It used a 1.3-megapixel Kodak KAF-1300 sensor, and a separate shoulder-mounted processing and storage unit. The DCS 200 series of 1992 condensed the storage unit into a module which mounted onto the base and back of a stock Nikon F-801s SLR. The module contained a built-in 80 megabyte hard drive and was powered with AA batteries. It was followed by the upgraded DCS 400 series of 1994, which replaced the hard drive with a PCMCIA card slot. The DCS 400 series included the 1.5-megapixel DCS 420, and the 6-megapixel Kodak DCS 460, which retailed for $28,000 on launch. In common with Kodak's later 6-megapixel models, the DCS 460 used the award-winning APS-H Kodak M6 sensor. A modified version of the DCS 420 was also sold by the Associated Press as the Associated Press NC2000. In parallel with the DCS 400 series Kodak also sold the analogous Kodak EOS DCS range, which was based on the Canon EOS-1N SLR. With the exception of the original DCS 100, these early models did not include LCD preview screens.
