The Canon EOS 650 is a 35 mm single-lens reflex camera. It was introduced on 2 March 1987, Canon's 50th anniversary, and discontinued in February 1989. It was the first camera in Canon's new EOS series, which was designed from scratch to support autofocus lenses. The EOS system featured the new EF lens mount, which used electrical signals to communicate between the camera and the lens. Focusing and aperture control were performed by electric motors mounted in the lens body. The EF mount is still used on Canon SLRs, including digital models. Canon's previous 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 (USM) EF autofocus lenses were also developed successfully for the 650. An EOS 650 was used in 1992 to take the first photographic image which was uploaded on the World Wide Web, a picture of the band Les Horribles Cernettes.〔(How the first photo was posted on the Web 20 years ago ), Andrew Hough, The Telegraph, 11 July 2012〕 The EOS 5D Mark III DSLR was announced on the 25th anniversary of the announcement of the EOS 650.〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Canon EOS 650」の詳細全文を読む スポンサード リンク
