Great idea for a thread! I've taken a number of landscape photos with my 77mm Limited that I'm very happy with:
Mule Ears, Big Bend National Park. 77mm Limited, f/11
I also have a number from my 55-300, most "out the window of the moving car" shots:
Montana. 55-300 @ 55mm, f/11.
Badlands National Park. 55-300 @ 300, f/11
For me, the best opportunities for telephoto landscapes, by far, are out of airplane windows:
California coast. 77mm f/2.5:
Pacific Northwest stratovolcano. 55-300 @ 170mm, f/4.5.
