    How do these compare wide open at 300mm? I know the 75-300 is fair, but I'm
    considering the 100-300 if it is much better.

    If you're looking for a (relatively) cheap and very sharp lens, then
    see if you can find a 100-300L. Dont let the 'L' part scare you off
    - it has been discontinued so it's quite cheap now, if you can fine
    one. It's a fixed f/5.6 but that probably wont matter if you shoot
    at the long end - the 75-300 and 100-300 will go to f/5.6 quite
    early in the zoom range anyhow. The main problem with it is that A)
    it's hard to find because they've stopped making it and B) it's a
    little slow to focus because it's the old-style micro motor rather
    than USM. But having said that, it's a nice sharp lens (It even has
    a flourite element at the front).

    How do these compare wide open at 300mm? I know the 75-300 is
    I have had them both and to me they are about equal but I like
    the ergonomics on the 75-300 better as well as the extended
    range. If you need the sharpest 100-300 the old L version
    is better.

  6. Primary advantage to the 100-300 over the 75-300 is that it is a true ring
    USM lens, meaning faster, quieter focus and a non rotating front element,
    critical when using oriented filters like graduated neutral density and
    polarizing filters. I like the 100-300's feel better, which, with the
    previously mentioned reasons, is why I bought one for my wife.

  7. And just how did you arrive at this glowing assessment?
