It was the first camera in Canon's new [[Canon EOS|EOS]] series, which was designed from scratch to support [[autofocus]] lenses. The EOS system features the new [[Canon EF lens mount|EF]] lens mount, which uses electrical signals to communicate between the camera and the lens.<ref>{{cite web|url=http://www.canon.com/camera-museum/camera/1987-1991/data/1987_eos650.html |title=EOS650 |author=Canon Inc. |author-link=Canon Inc. |work=Canon Camera Museum |accessdate=3 October 2006 |archiveurl=https://web.archive.org/web/20060827013946/http://www.canon.com/camera-museum/camera/1987-1991/data/1987_eos650.html |archivedate=27 August 2006 |url-status=dead }}</ref>
Focusing and aperture control are performed by [[electric motor]]s mounted in the lens body. The EF mount is still used on Canon SLRs, including digital models. Canon's previous [[Canon FD|FD mount]] lenses are incompatible with EOS bodies.

Canon's first EOS camera had the latest technologies, including a microprocessor and a Canon-developed '''BASIS''' sensor for high-precision AF. Canon claimed incomparable autofocusing for the EOS 650. A range of high-precision [[ultrasonic motor]] EF autofocus lenses were also developed successfully for the 650.

An EOS 650 was used in 1992 to take the first photographic image that was uploaded on the [[World Wide Web]], a picture of the band [[Les Horribles Cernettes]].<ref>[https://www.telegraph.co.uk/technology/news/9391110/How-the-first-photo-was-posted-on-the-Web-20-years-ago.html How the first photo was posted on the Web 20 years ago], Andrew Hough, The Telegraph, 11 July 2012</ref>
