Ok, I am a little perplexed. Why are we talking about the 16-35, 17-55, or even the 17-40 all of which are good 'standard' lenses when what he needed is an UW lens. In that category you have a limited number of choices ranging from the Canon 10-22, Sigmas, Tamron, and Tokinas that all cover a similar range. The OP does landscape photography so he needs wide. The bottom line is that the 10-22 is the best cropped sensor UW zoom of the bunch with the Tokina 11-16 and 12-24 coming up next and the Tamron/Sigma being strong finishers. Depending on the lens you get, your quality will vary from lens to lens. The quality variation is less with the Canons.
Sorry to have sounded cranky, I was -- tough morning and I could have phrased it better. I have had a 20D, 40D and now use a 5D. I used the Tokina 12-24 with my 20D and 40D and enjoyed the lens. The 10-22mm was used only with the 40D and I loved that lens though for number of reasons I did not use it as much as I wish I had. Mostly because I had a 17-50 2.8 Tamron that I loved. When I made the switch to the 5D I sold the 10-22mm and picked up a nice 17-40 which I love, especially because it was a straight swap for the 10-22mm and became my 1st piece of 'L' glass.
