Editing Autofocus (section)

==History==
Between 1960 and 1973, [[Ernst Leitz GmbH|Leitz]] (Leica)<ref>{{cite web|url=http://www.lfi-online.com/ceemes/page/show/issue_4_09_3 |title=S System: Autofocus – Leica Fotografie International |access-date=2009-05-15 |url-status=dead |archive-url=https://web.archive.org/web/20090621131329/http://www.lfi-online.com/ceemes/page/show/issue_4_09_3 |archive-date=2009-06-21 }}</ref> patented an array of autofocus and corresponding sensor technologies. In 1976, Leica had presented a camera based on their previous development at [[photokina]], named Correfot, and in 1978 they displayed an SLR camera with fully operational autofocus. 

The first mass-produced autofocus camera was the [[Konica C35 AF]], a simple [[point and shoot camera|point and shoot]] model released in 1977. The [[Polaroid SX-70]] Sonar OneStep was the first autofocus [[single-lens reflex camera]], released in 1978. 

The [[Pentax ME F|Pentax ME-F]], which used focus sensors in the camera body coupled with a motorized [[photographic lens|lens]], became the first autofocus 35&nbsp;mm [[Single-lens reflex camera|SLR]] in 1981. 

In 1983 [[Nikon]] released the [[Nikon F3#F3AF|F3AF]], their first autofocus camera, which was based on a similar concept to the ME-F.<ref>{{cite web |url=https://imaging.nikon.com/imaging/information/chronicle/history-f3/ |title=Debut of Nikon F3 |website=Nikon |access-date=Nov 10, 2024}}</ref>

The [[Minolta 7000]], released in 1985, was the first SLR with an integrated autofocus system, meaning both the AF sensors and the drive motor were housed in the camera body, as well as an integrated film advance winder&nbsp;— which was to become the standard configuration for SLR cameras from this manufacturer, and also Nikon abandoned their F3AF system and integrated the autofocus-motor and sensors in the body. 

[[Canon (company)|Canon]] decided to discontinue their [[Canon FD lens mount|FD mount]] and switched to the completely electronic [[Canon EF lens mount|EF mount]] with motorised lenses in 1987. 

[[Pentax cameras|Pentax]] was the first to introduce focusing distance measurement for SLR cameras with the FA and FA* series lenses from 1991. Their first [[Pentax K-mount|K<sub>AF</sub>-mount]] [[Pentax (lens)|Pentax lenses ]] with AF had been introduced in 1989.<ref>{{cite web|url=http://www.aohc.it/catalogo.php?catalogo=oggetti&id_catalogo=44&filtro%5btipologia%5d=13 |title=Milestones - Asahi Optical Historical Club |access-date=2021-08-29}}</ref>

In 1992, Nikon changed back to lens integrated motors with their AF-I and AF-S range of lenses; today their entry-level DSLRs do not have a focus motor in the body due to the availability of motors in all new developed [[List of Nikon F-mount lenses with integrated autofocus motor|AF-Lenses]].
