I use this lens with my Canon 5D and together with the Sigma 70-200 f2.8 EX it is my favourite zoom lens. I also have the Sigma 24-70 f2.8 and the 12-24.
What impresses me about this lens is the lack of distortions and vignetting and its sharpness and colour rendition. I usually focus it manually so can't really comment on auto-focus. It's one of those lenses that IMO match primes for quality throughout its short zoom range. The only thing that makes it miss a 10/10 score is that there is a tendency to fringing, easily fixed in PP of course.
