Excellent optical quality

Summary: Excellent optical quality, very nice physical construction and very useful focal lengths range on a full frame camera. There's a bit of chromatic aberration but it can be easily fixed in Lightroom. All in all, my favorite lens on my 5DmkII.
Summary: This is my first wide angle lens and I love it. Great pictures with my Canon EOS 6d. Could take pictures in low light settings and the images were still great. I love the angle I can get with this lens inside and outdoors.
Summary: As one would expect from L-series glass, clear with good contrast and color. Great lens for hiking as it's quite light compared to other lenses. Really gives a lot of flexibility in what kind of foreground you can place in front of a scene, as it's quite wide.
I used to have a 7D with a 11-16mm Tokina and the images always looked like fish eye

Summary: Solid lens. I have a full frame 6D and this camera shoots well with this. The wide angle distortion doesn't bother me at all. I used to have a 7D with a 11-16mm Tokina and the images always looked like fish eye. This lens doesn't bother me at all.
