Which 18-135 lens do you have? Canon has made 3 of them. If you have your heart set on a Canon L lens for landscape and general walk around, there really aren't any other choices than the 24-105. Sure there is the far superior 24-70 f/2.8, but it's very expensive, heavy, and has an even more limited focal range. Personally, I would find 24 mm not wide enough on a crop camera, but many people happily live with it.
