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.
