The EOS 20D is the semi-professional digital SLR to deliver all the speed, precision and flexibility synonymous with high-end film SLR cameras - plus a whole lot more. A rugged magnesium alloy body provides the first clue that the EOS 20D is no ordinary camera. Canon's award-winning CMOS technology delivers outstanding image quality and 8.2 Megapixel resolution. The DIGIC II architecture drives blistering 5fps continuous shooting with a maximum burst of 23 frame JPEG images, class-leading color rendition accuracy, quick start-up times and rapid display and zooming of images during in-camera review. JPEG and RAW files write simultaneously with no loss of performance. 9 auto focus points are carefully distributed across a wide area of the frame for fast, accurate focusing, even with off-center subjects and particularly with 'rule-of-thirds' compositions. The E-TTL distance-linked flash algorithm takes factors such as lens distance information and ambient light readings into account for accurate flash metering, even in circumstances such as recomposed shots, or where high or low reflective objects appear in the frame. The camera is compatible with the entire EX-series Speedlite flash range. This includes the 580EX, which transmits color temperature information for improved color stability and auto zooms to match the camera's APS-C sensor size. The EOS 20D is compatible with more than 60 Canon EF lenses, including Canon's EF-S lenses. Built with the EOS 20D photographer in mind, the EF-S 10-22mm f/3.5-4.5 USM and EF-S 17-85mm f/4-5.6 IS USM cover popular wide (approx. 16-35mm) and standard (approx. 27-136mm) ranges in the 35mm equivalent. An extreme high (3200 ISO) setting extends the camera's wide 100-1600 ISO speed range. Both sRGB and Adobe RGB color spaces are supported. Digital Photo Professional image processing software permits high-speed processing of lossless RAW files. The EOS 20D's USB 2.0 Hi-Speed connection enables fast download of images to the computer. PictBridge compliant, the camera supports direct printing to any compatible photo printer. It takes both CF and CF-II cards, including cards of over 2GB capacity.
