    Hi all

    Anyone else heard of problems with dark corners on photos shot at wider end
    of the lens, using a Canon 20D and 18-85IS lens?

    I initially thought that maybe it was due to the lens hood or maybe even the
    UV filter, but even with these removed I still get vingetting.

    It is worse during dusk/dawn and is particularly noticeable against a clear

    A fault, or so called characteristic?

    the 17-85 USM IS is a toy. Return it and grab a 17-40 L instead

  3. I agree with that. I'm just getting a body and that as well as other
    lenses. I'm not getting any of the EF-S lenses.

    You can get a body and that lens 2049 and change at B&H and have a
    far better system.

    You could speak of a Texas boy's growth as his .410, his 20
    and 12 guage years."

  4. The 10-22 is a _lot_ of fun. It focuses _amazingly_ close, too.

  5. If you shoot a cheap consumer zoom wide open, and a L lens stopped down to
    f/5.6, you should be able to see the difference. Things like CA, soft
    corners, light fall off are visible in prints.

    The argument for cheap zooms, however, is that _any_ photograph is better
    than _no_ photograph.
