I've held off on buying this lens because of some of the reviews that I've read have given it such mediocre reviews. I love my 24-70 (even more than just the value), but I think Sigma has work to do on this range before it is quality competitive.
The only focal length I see a notable difference (Canon being better) throughout the entire aperture range is at 200mm. Everything else is a wash.
