While this is totally subjective, I don't agree that you need a wide angle at all to shoot a good landscape. In fact, I find it much harder to shoot a good landscape with an wide/ultrawide than it is with a moderate wide or normal lens (in the 20 - 35mm range).
I actually use my kit lens more for landscapes than my 15. Crazy, right?
I suppose I'm simply suggesting to be sure you are buying this lens for the right reasons. Wide angles are expensive, but zooms in the moderate wide-normal range are very cheap.
My personal fav landscape lens was the A 28mm f2.8. Crazy sharp stopped down, and a great focal length for landscapes.
