    Crystal, I am able to achieve better sharpness with all my Canon and Sigma lenses if I turn off auto focus and just manual focus. I truly believe the AF on my 40D stands for "approximate focus" Give it a try. Take two photos, using a tripod. Auto focus one then switch to manual focus for the second photo. Then compare the two on your computer monitor. I bet the manual focus shot is sharpest. Hope this helps - jimmy ...

    Almost forgot, shoot at F8 or so and a fast shutter speed.

    I don't have any trouble with my auto focus on either of my 40D's with my Canon lenses. However, I've never done a manual comparison.

    Mad , I am about to switch to the Nikon D700. It would be so nice to rely on auto focus but I cannot! All my lenses manual focus sharper so it must be my camera - jimmy

    Mad, just try the comparison and possibly you may be surprised. One really cannot tell just by looking at the back camera screen. It must be compared on your computer monitor - jimmy

    Will you be able to take REAL photos with that one do you think?

    i felt a lot of frustration with focusing as well... it is one of those things that has many elements to it...
    fstop. motion. and calibration.
    yup. calibration.
    here is a website that you may find useful... or, then again, maybe not
    LensAlign® Focus Calibration System

    ps... with my nifty50 f1.8, i use manual focus only.

    One day I'm sure you'll surprize me and post up a stunning, full colour photo with no added filters just to prove you can do it

    Hi tt, thank you for the link. I have used similar test charts. They showed my AF does not focus on the spot I cover with my focus point! Thanks again for the advice - jimmy.
