In 1991, Kodak released the first commercially available digital SLR, the Kodak DCS-100. It consisted of a modified Nikon F3 SLR body, modified drive unit, and an external storage unit connected via cable. The camera was capable of producing 1.3 megapixel (1280x1024) and cost approximately $30,000 US. This was followed by the DCS-200 with integrated storage.[2]

Over the next decade, digital SLRs have been released by various companies such as Canon, Nikon, Kodak, Pentax, Olympus, Konica Minolta, Fujifilm, and Sigma with higher resolution and lower prices.

In January 2000, Fujifilm announced the finepix S1-pro which was the first DSLR that had a 'resonable' price and was marketed to non-professionals.

In 2003, Canon introduced a 6.3 megapixel Digital Rebel SLR camera (known in the UK as the EOS 300D) at an MSRP of under $1000. Its popularity, especially among newspaper and amateur photographers, encouraged other manufacturers to produce affordable digital SLR cameras, significantly lowering entry costs and allowing more casual photographers an opportunity to experience the digital SLR photography. Canon introduced the next generation 8 megapixel EOS350D (Digital Rebel XT) in 2005.

In February 2004, Kodak released two 14-megapixel full-frame (24x36mm) DLSRs named Kodak DCS 14 N and DSC 14 C, one for Nikon lens mount and one for Canon lens mount. These cameras were expensive, and not very sensitive, and Kodak has since discontinued them. Konica Minolta briefly produced two DSLR models, the 5D and 7D, but has sold their digital camera business to Sony which revamped the range through its alpha brand. At one time, Kyocera also manufactured DSLRs and marketed them under the Contax name,[3] but in 2005 withdrew from the DSLR camera field. Sigma produced the SD9 and SD10 DSLR cameras with the Foveon X3 sensor, but those cameras are no longer in production; a successor has been promised but not yet announced.
