Phil, I'd say these look pretty good. I did some with the 17-40 f4 and 24-105 f4 in the past and found that both were decent lenses when used in NCAA lit gyms or with strobes. The one thing I don't like as much is that some of the shots seem a little overly contrasty for my taste. I like some punch as much as the next guy (figure of speech to those ladies who might be reading) but some of these seem a bit too much. Consider a fairly low opacity high pass filter to crisp things up, then some USM sharpening.if needed still. Last step is add a low opacity (Im talking 5-10%) soft light layer to give your colors some zing and add contrast. Its largely personal taste but that's what I do so I thought I'd throw it out there.
So, you really are a Dr. Phil, huh? Sweet.
