I have heard very good things about the IQ of the Sigma, though I don't believe all copies of that lens are create equally (search the alt forums here as I believe there were definitely some issues with this lens that may have been fixed by now - AF maybe?). I love the Canon 50 1.4, though my copy (and I believe this is somewhat characteristic of the lens in general) is quite soft wide open (until about F2). I found a few image samples of the canon 50 1.4 (all snapshots), though I couldn't find any wide open (which may be quite a good indicator of how many keepers I have at that aperture). I realize now that I have far more keepers at 1.4 with my 35L then I do with my 50 1.4 (though that could be because I use it far less now). One of these shots is not a person, but will show you the lens at F2.
