Soon after I purchased my 70-200mm IS II, I twisted my wife's arm into posing in the back yard. The attached photo was shot with a 40D at 135mm (actual focal length), 1/400, f/5 & ISO 400. You can count each eyebrow hair with no difficulty. I couldn't be happier with the sharpness, but Terri doesn't like the fact you can see she isn't 30 years old! (She was 63 at the time the photo was taken.) The 40D has no fancy AFMA, and only 9 focus points, but from my perspective it is tack sharp. I couldn't be happier with the lens on any of the bodies I have.
