I've had this camera for a month now after having the 30D for the past 3 years and using a 5DMk2 for a few months. This camera is a perfect blend of the x0D series and xD series of cameras. If it were a full frame camera, it would definitely be a pro grade camera.
Great picture and video quality; Build Quality is superb; Autofocusing; Great low-light performance at high ISO; Battery Life
No dual CF slots; No 1D-level weather sealing; Incandescent WB preset still not close enough
