Lens review site.

Here's a neat site I just stumbled onto. It offers slick plots of various lens performance parameters for a number of popular (d)slr lenses. Maybe worth a look...
heh - I was just looking for one of these today. I need to get a better zoom lens before storm season hits. Somewhere around 20-70mm that has a fast, sharp autofocus is what I'm looking for (Canon) ... don't want to spend much more than $500 if I can help it - - - will take a look at those sites to see what the going recommendations are.
