Cons: Bad optical characteristics on 17-20 mm: significant CA and soft corners.
Pros: Wide angle, light and small, cheapest L-lens in Canon's range, well build.
Summary: I'd to change this lens on the either Canon 24-70 2.8 or new Tamron 24-70 2.8 VC to have the same working wide end. And also f2.8, and also 70 mm :)

Pros: superb build quality, sharp pictures, cheap price (for L series) ultra sonic motor, full time manual focus doesn't extend when zooming

Cons: Slight barrel distortion at wide settings, some corner CA.
Pros: Very well built, excellent price for L lens, performance generally very good.
Summary: Great lens for the money, especially when compared with 10-22 which is still great. Barrel distortion is quite noticeable at 17mm and that is probably its only drawback. Great performance at f/8.

Cons: not as sharp than other L-lenses, at fullframe weeker
Pros: good resolution, NO(!) CA´s, NO(!) light falloff, distortion easy to fix, fantastic build quality, good price
Summary: Its a lens nearly without faults, at APS-C nearly perfect, fullframe just good. The prize is a nice surprise (that sounds really poetic!). Get one for APS-C and use it later as fullframe!
