Hi Guys.
I find this site excellent for comparing just about any two lenses from a few
lens vendors you like, although not completely exhaustive.
http://www.the-digital-picture.com/Reviews/ISO-12233-Sample-Crops.aspx?Lens=113&Camera=453&Sample=0&FLI=7&API=0&LensComp=683&CameraComp=453&SampleComp=0&FLIComp=5&APIComp=0
Just run your cursor over the image to swap between the two lens captures. The
default is the left-hand lens, in this case the Canon, and the cursor on the
image will bring up the compared lens, in this case the Sigma. You can check
different apertures, different focal lengths (on the zooms) and if you go into
the reviews section of the site, Brian gives some excellent advise on a pile of
lenses, Canon in particular, since that is what he uses on a day to day basis.
