The EOS 650 (QD) is the first AF single-lens reflex camera with a completely electronic EOS system, integrated metering and motor drive focusing built into the EF lenses. It also incorporates new proprietary technology such as an ultrasonic motor “USM” and a highly sensitive sensor “BASIS.”
* The EOS 600 also has a wide range of other features such as a built-in motor drive (3 frames/sec.) and six program AE modes including depth-of-field priority AE.
* The QD model supports the following five imprint date items: date (three types), day/hr/min, any 6-digit numeral, a 4-digit frame counter, and imprint OFF.
* Use of the 300EZ enables use of AF Illuminator for autofocusing in low light.
