Hello everyone. I've had my 20D for a couple months now and I'm fighting with the focus (i think). I have the camera setup so the sharpness it turned up 100%. I fight this slight fuzzy on just about every photo. Sometimes I will get a perfect focus but rare. Click on the photo below to see the original and you see on the child's face what I'm talking about. I'm aiming at his nose on this photo.

Please Help!!!

    I'm surprised that the camera chose such a high AV. I would think 5.6 or even lower would be fine for a shot like this.

    Also, in outdoor light, especially during peak sunlight, I recommend at least -0.33 0r -0.67 EC.

    Is this on all lenses that you this issue? What lens did you use on this one.

    And just for giggles, make sure the lens didn't get switched to MF. I know it happens a lot on my 70-200 and also on the Tamron 28-75 I used to have.

    Did you focus and recompose?
    His shirt looks more in focus than his face.
    Were you using the center focus point?
    What lens are you using or does this happen on all lenses?
    I thinks at f10 he should be all in focus.

    Does your camera have one of those adjustable viewfinder's? Could be set wrong.

    There's a great thread in fredmiranda.com that covers the 20D focusing topic. Here's a link:

    http://www.fredmiranda.com/forum/topic/241524

    In summary though, the autofocus is good to within some tolerance. When you blow up shots on the screen (like we all tend to do when evaluating our digital images) you will see defocused portions of the image because the tolerances are set for 6 x 9 print viewed from 10 inches away.

    Try stoping down a bit more to get more depth of focus. This will help your exposure as well.

    This brings up a question. How do you know if the diopter is set wrong? I usually look through the viewfinder and set the diopter to what looks best to me...but, that will be wrong (relative to what the CCD/CMOS chip sees) if the camera lens is slightly defocused (i.e., the diopter setting is compensating for the lens defocus).
