What is Canon EOS?
The '''[[Canon (company)|Canon]] EOS''' ('''Electro-Optical System''') is an [[autofocus]] [[135 film|35 mm]] [[photographic film|film]] and [[digital photography|digital]] [[single-lens reflex camera|SLR]] camera system that was introduced in [[1987]] with the [[Canon EOS 650]] and is still in production as Canon's current [[Digital single-lens reflex camera|dSLR]] system. The [[acronym]] [[EOS]] was chosen for [[Eos]] in [[Greek mythology]], and is often pronounced as a word (i.e., ''EE-oss''), although some spell out the letters, reading it as an [[initialism]]. Both pronunciations are acceptable as there is no official pronunciation. 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]]. In most countries, EOS cameras have the largest market share of SLR cameras.<ref>{{Cite web|url=https://petapixel.com/2019/07/08/canon-increased-market-share-in-2018-but-camera-market-continues-to-bleed/|title=Canon Increased Market Share in 2018 But Camera Market Continues to Bleed|website=petapixel.com|access-date=2020-07-18}}</ref> ==References== {{reflist}} {{tech-stub}} [[Category:Cameras]]
