How does the image quality of the Digital Rebel XT compare to that of the EOS 20D? Well, I took a few shots with both cameras in normal daylight set to the same ISO, parameter settings (contrast, sharpness, saturation etc.) and using the same lens.
My conclusion is that both cameras produce images of essentially the same quality, both at ISO100 and at ISO 1600. Color and noise levels were very similar indeed. Without doing scientific tests, they look identical, even at 200% enlargement. Any fears about higher noise or lower sharpness seem totally unfounded
