Digital SLRs (DSLRs)
- Nikon was interested in digital photography since the mid-1980s. In 1986, while presenting to Photokina, Nikon introduced an operational prototype of the first SLR-type digital camera (Still Video Camera), manufactured by Panasonic. The Nikon SVC was built around a sensor 2/3 " charge-coupled device of 300,000 pixels. Storage media, a magnetic floppy inside the camera allows recording 25 or 50 B&W images, depending on the definition. In 1988, Nikon released the first commercial DSLR camera, the QV-1000C.
In 1991, Kodak brought to market the Kodak DCS (Kodak Digital Camera System), the beginning of a long line of professional Kodak DCS SLR cameras that were based in part on film bodies, often Nikons. It used a 1.3 megapixel sensor, had a bulky external digital storage system and was priced at $13,000 (equivalent to $24,000 in 2019). At the arrival of the Kodak DCS-200, the Kodak DCS was dubbed Kodak DCS-100.
The move to digital formats was helped by the formation of the first JPEG and MPEG standards in 1988, which allowed image and video files to be compressed for storage. The first consumer camera with a liquid crystal display on the back was the Casio QV-10 developed by a team led by Hiroyuki Suetaka in 1995. The first camera to use CompactFlash was the Kodak DC-25 in 1996. The first camera that offered the ability to record video clips may have been the Ricoh RDC-1 in 1995.
In 1995 Minolta introduced the RD-175, which was based on the Minolta 500si SLR with a splitter and three independent CCDs. This combination delivered 1.75M pixels. The benefit of using an SLR base was the ability to use any existing Minolta AF mount lens. 1999 saw the introduction of the Nikon D1, a 2.74 megapixel camera that was the first digital SLR developed entirely from the ground up by a major manufacturer, and at a cost of under $6,000 (equivalent to $10,100 in 2019) at introduction was affordable by professional photographers and high-end consumers. This camera also used Nikon F-mount lenses, which meant film photographers could use many of the same lenses they already owned.
Digital camera sales continued to flourish, driven by technology advances. The digital market segmented into different categories, Compact Digital Still Cameras, Bridge Cameras, Mirrorless Compacts and Digital SLRs.
Since 2003, digital cameras have outsold film cameras and Kodak announced in January 2004 that they would no longer sell Kodak-branded film cameras in the developed world – and 2012 filed for bankruptcy after struggling to adapt to the changing industry.
