12-35 unimpressive as a landscape lens

I'm not surprised given my 14-45mm is a better landscape lens than my Nikon 17-55mm f/2.8. I suppose the 17-55 and 12-35 are designed for event photography and photo journalism. This hasn't stopped me from getting landscapes out of the 17-55 that look great at 13x19. I just know my 12-24 and Panny 14-45 are a bit better. My Oly 12-50mm really softens up at the corners, and isn't as sharp at the center either... Which is why I haven't sold the 14-45mm. Now I have seen landscapes from the 12-35mm that look amazing on the Web, but Ipeeping pixel peeping or looking at large prints.

I did buy a used 9-18mm, which so far seems excellent. If it compares well to my 14-45, I might sell the latter and use the 9-18 as my main landscape lens.
