The Canon EOS-30D is the latest in Canon's broad line of digital SLR models, but it is more evolutionary than revolutionary, keeping most of what was excellent about its predecessor, the EOS 20D. Canon says they listened to feedback from 20D customers and made modifications to make an even better 20D. The resulting Canon 30D still has the same 8 megapixel sensor, main processor, and basic body design of the 20D, but it's been augmented with a larger screen, a more durable shutter, and a 3.5% spot metering mode, among other improvements..
