Canon 20D
It was rumored, now it's official. The new Canon 20D looks like an impressive successor to the 10D. The sensor is 8 megapixels. It still has the same 1.6x field of view crop as the 10D. I was hoping for a bigger sensor so my wide angle lenses would give me a wider field of view than on the 10D.
Start up time is much faster, it shoots at a maximum of 5 frames per second vesus 3 fps on the 10D, and it has a bigger buffer.
