Cons: Using the lens wide open is a complete non-starter because the corners are simply unusable. For landscape or architecture photographers that doesn\'t matter a jot. On modern cameras and the widest focal lengths you must set to f11. Don\'t be afraid to set to auto ISO and you can easily keep the camera still enough to hand hold if you also enable a minimum shutter speed in advance.
Pros: Build quality is truly excellent, micro contrast impressive and colour rendering as good as you\'ll get. It isn\'t possible to get an adequate ultra wide-angle for full-frame in a native Canon EF lens from any other lens unless you have a lot of money to spend.
Summary: Showing its age somewhat and necessary to take certain precautions in order to achieve very good image quality at the widest end, but a bargain buy for what it is capable of producing.

Cons: Typical characteristics showing in all wide angle lenses. Many of these can be dealt with in Photoshop or DxO which can minimize all the typical complained about wide angle issues.
Pros: Well valued L lens which is great for FF but alternatively will work with crop sensor. Decent build and used market prices these at a commodity level. Some great values and even new with current rebate a very fair value.
Summary: Great value lens that fits physically fits both camera types. Simply a very good lens for landscapes and any issues can be easily rendered out of the final print or presentation.

Cons: Waviness distortion, hood shape, it should be better if it has IS * Not good idea to using on APS-C
Pros: Zoom length is good for landscape and travelling on FF, best flare and ghost resistance in this lens class on Canon FF, Good IQ when choose the right aperture for each focal length, light, weather seal
Summary: Great choice for Canon Landscape and travelling

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 :)

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!
