    Hi, I am looking for user comparisons between the following Canon 75-300mm
    f/4.0-5.6. USM or 100-300 f/4.5-5.6 USM.
    Lenses will be used on a 20D for sport and wildlife. Autofocus is
    important - poor eyesight!!

    The lenses are about equal in optical abilities. If using polarizors is
    important to you get the 100-300 as the front element does not turn while
    focusing. If you hand hold most of teh time consider the extra for the
    75-300 IS. This lens appears much sharper from the stabilization.

    I have the 75-300 IS and agree about getting the IS if you are going to hand
    hold. However, if you are going to use it for wildlife and sports action
    shots, you may be disappointed in the auto focus speed.

    Another thing to consider is that the "reach" of this lens, on a 6MP
    camera with a 1.6x crop factor, is already limited by the lens, and a
    teleconverter will not "reach" any more subject detail. The better
    telephoto zooms have more detail that can be pulled with a TC in
    sufficient lighting.
