YES, I do have the autofocus problem. Taking portrait shots from about 6' away the pictures didn't look as sharp as I expected when my f-stop was below F4. At F5.6 they looked much better. Did some ruler tests, with my 50mm/1.4 and 70-200/4L. Focus point would be about 1/2 to 1 inches behind the target from about 4 feet away. This is significant when using fast f-stops, the DOF is very narrow. Will be sending in to canon for calibration. Got camera for a good price from dell so I don't want to return it and lose that price. THe calibration should be easy enough.
I shoot with a 10D and at first I thought I might have a problem. Now I think I just wasn't using it correctly. I read a lot of posts on dpreview about how to use the autofocus correctly and that has helped me a lot.
