Canon EOS 650
The Canon EOS 650 was the first SLR single-lens reflex camera in the EOS series, introduced in March 1987. It also heralded the autofocus EF lens mount, which replaced the manual-focus FD mount - it must be pointed out here that the two mounts are not compatible.
Canon's first EOS camera had the latest technologies including a super microcomputer and a Canon-developed BASIS sensor for high-precision AF. The EOS 650 boasted incomparable autofocusing. Each EF lens has its own optimum built-in motor for autofocusing, and only electronic signals are exchanged between the lens and camera body. Since there is no high-torque driving noise, autofocusing is quick.
The high-precision Ultrasonic Motor (USM) range of EF autofocus lenses was also developed successfully for this camera. It is a tribute to Canon that these lenses are still compatible with the latest range of EOS film and digital cameras including the brand new Canon EOS-350D.
