I cannot tell you how many times I’ve watched photographers walk up to a grand scene and without even thinking, grab a wide-angle lens and shoot. Just because the scene in front of you is expansive does not mean a wide angle is automatically the best choice. Telephoto zoom lenses are perfect for optical extractions. Simply using a telephoto lens to isolate interesting compositions within the grand landscape. Many times the graphic lines within the overall scene are far more interesting than the whole scene. Simply choose whatever focal length lens allows you to compose a strong composition. Force yourself out of your comfort zone, try a few different compositions with a telephoto, and open up a whole new way of seeing.
A polarizing filter is a good idea for removing distant haze. Also check your live view to confirm focus is perfect, and stop the lens down enough for the appropriate depth of field for the scene. Lastly, lock your mirror up to reduce any vibration.
