I'm having doubts as to the quality of image I'm getting from my new 40d. I just got it to replace a rebel that has back focus issues. You can see the issues in the next two links. The 40d appears to be focusing properly: http://www.thrive.ca/photos/dof-rebel.jpg http://www.thrive.ca/photos/dof-40d.jpg and here's a couple of raw files comparing the two focusing on the label of the bananas: http://www.thrive.ca/photos/compare.zip Should I be expecting something sharper out of the 40d? What level of sharpness should reasonably be applied to a raw file? DATA: Rebel xti compared to a 40d with a 24-70 L USM.
