'''Canon EOS''' ('''Electro-Optical System''') is an [[autofocus]] [[single-lens reflex camera]] (SLR) and mirrorless camera series produced by [[Canon Inc.]] Introduced in 1987 with the [[Canon EOS 650]], all EOS cameras used [[135 film|35 mm]] [[photographic film|film]] until October 1996 when the [[Canon EOS IX|EOS IX]] was released using the new and short-lived [[Advanced Photo System|APS]] film. In 2000, the [[Canon EOS D30|D30]] was announced, as the first [[digital photography|digital SLR]] designed and produced entirely by Canon. Since 2005, all newly announced EOS cameras have used digital [[image sensor]]s rather than film. The EOS line is still in production as Canon's current [[digital SLR]] (DSLR) range, and, with the 2012 introduction of the [[Canon EOS M]], Canon's [[mirrorless interchangeable-lens camera]] (MILC) system. In 2018 the system was further extended with the introduction of the EOS R camera, Canon's first full frame mirrorless interchangeable lens system.

The development project was called "EOS" (Electro Optical System). EOS is also the name of [[Eos|the goddess of dawn]] in Greek mythology, which further signifies the design's generational stature.<ref>{{Cite web|url=https://global.canon/en/c-museum/history/story07.html|title=View by period - 1987-1991 - Canon Camera Museum|website=global.canon}}</ref>

The EOS emblem was created using [[Handel Gothic]] typography.

It competes primarily with the [[Nikon F]] series and its successors, as well as autofocus SLR systems from [[Olympus Corporation]], [[Pentax]], [[Sony]]/[[Minolta]], and [[Panasonic]]/[[Leica Camera|Leica]].<ref>{{cite web|url=http://www.canonrumors.com/2011/04/canon-destroys-nikon-in-dslr-marketshare/|title=DSLR Worldwide Market Share, 2010|date=20 April 2011 |access-date=2 May 2011|archive-url=https://web.archive.org/web/20110426104707/http://www.canonrumors.com/2011/04/canon-destroys-nikon-in-dslr-marketshare/|archive-date=26 April 2011|url-status=live}}</ref>

At the heart of the system is the [[Canon EF lens mount|EF lens mount]], which replaced the previous [[Canon FD lens mount|FD lens mount]], which mainly supported only manual-focus lenses. The EOS R full frame camera introduced a new lens mount to the system – the [[Canon RF mount|RF mount]].
