Canon EOS 20D

Canon EOS 20D is the digital still camera from Canon.

It has an advanced DIGIC II imaging engine, it achieves an amazing 5fps consecutive shooting speed during maximum bursts of 23 shots (6 shots in RAW format) — even when shooting in the Large/Fine JPEG setting (approx. 3,504 x 2,336 pixels. High-speed 4-channel reading, an accelerated mirror driving system, and faster recording to the CF card make this feat possible.

When fleeting shutter opportunities arise, the remarkably quick startup (approx. 0.2-seconds) and short shutter release time lag (0.065 secs) help the photographer to capture the moment without any delay [because of the high-speed mirror drive].

A shortened viewfinder blackout time further decreses the time needed for it to respond.
