    My Canon Digital Rebelwith 18-55 kit lens is giving me problems. More
    particularly, the auto focus function hardly ever works. When I
    semi-press the shutter release, the green AF light flashes to show it
    can¹t focus. The camera makes a short sound as if the lens is going to
    move to focus, but it generally doesn¹t. If I manually focus the camera
    to be almost right and then set the lens to AF again, it quite often
    manages to do the final bit itself, but if the initial focus is out, it
    always fails.
    This is not just in poor light conditions but also outside during the
    day focussing on wel lit and contrasted objects.
    I¹ve tried the camera with a friend¹s Sigma lens and then it focusses
    fine. I¹ve also tried my kit lens with my friend¹s own Digital Rebel
    and then that works fine, too. So it¹s a combination problem between my
    camera and my lens.

    I don¹t know if it¹s related, but I have occasionally gotten Error 99

    Has anyone has these or similar problems or have any tips on what to

    Many thanks in advance.

    Doesn't sound right to me... I have the 20D with 18-55 (have used two
    different ones) and it focused very well, if a bit noisier than my L glass

    I'd take it in and show the sales dude...

    Send it to Canon it needs adjusting/servicing.

    If it's still under warranty it's free if not £144 GBP.

    During such difficult times my Canons and lenses often benefit from a little
    tender loving care in the contacts area with a little piece of soft leather
    I keep around for that exact purpose.

    My Digital Rebel works fine with the same lens. I have never gotten any
    kind of error message with it. Perhaps your camera needs a good cleaning.

  8. Agreed. Sounds like contacts are not clean or not mating.

    You are such a comic. I almost smiled.
