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!!
Thanks

Find their MTF charts at Canon and use that for comparison.

Here's how to use that information.

"Did you really think we want those laws observed?"
said Dr. Ferris. "We want them to be broken. You'd
better get it straight that it's not a bunch of boy
scouts you're up against... We're after power and we
mean it... There's no way to rule innocent men. The
only power any government has is the power to crack
down on criminals. Well, when there aren't enough
criminals one makes them. One declares so many things
to be a crime that it becomes impossible for men to
live without breaking laws. Who wants a nation of
law-abiding citizens? What's there in that for anyone?
But just pass the kind of laws that can neither be
observed nor enforced or objectively interpreted - and
you create a nation of law-breakers - and then you
cash in on guilt. Now that's the system, Mr. Reardon,
that's the game, and once you understand it, you'll be
much easier to deal with."

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 a 75-300 IS and here is a sample taken at full zoom, hand-held:

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.

Hi,
Have you thought of the Canon EF 28-300 IS L lens? Expensive and heavy but it is an L
lens and focuses very quickly.
