10 out of 10 points and recommendedreally sharp, also in the corners at wide apertures, fast and silent AF, very useful and silent IS, good build quality, great IQI haven't discovered any yet
I love this lens. Bought it a few months ago and have used it a couple of times with my 5dIII, which produces tack sharp images, even at wide apertures. I had the 17-40 mm/4.0 L which is soft at wide apertures, especially in the corners. Not this lens! CA is well controlled, so is distortion. Thanks to IS I can shoot at 1/15 second manually and still produce tack sharp results. It works very silent too. It also balances nicely with my camera body with battery grip. And it looks good too. The lens hood is clickable and not as bulky as my old lens hood. I think I will use it more often now.reviewed May 28th, 2016 (purchased for $1,110)
It matches with my Sigma 50 mm/1.4 Art lens very well. These are the lenses I use most of the time. They are both great lenses and work for me in my profession as a reporter.

If you still own the 17-40 mm/4.0 L you should upgrade. It is absolutely worth it.
10 out of 10 points and recommendedSharpness, contrast, IQ, everything reallyA bit heavy
I have been using this lens for several months now and I absolutely love it. IQ, sharpness, contrast and colours are excellent, even wide open.reviewed July 29th, 2015 (purchased for $921)
It is a bit heavy, yes. But it balances well with my Canon 5d3 plus battery grip. No problem for me. I like the quality feel it gives me, it is very well constructed too.
AF works silent and swift, but sometimes struggles wide open in low light conditions.
