Many people buy a long lens specifically for photographing birds or other wildlife. Although I use my 500mm lens for those subjects, I also enjoy using the lens for capturing landscapes. A long lens is useful for condensing a scene.
While taking photographs at the Santa Fe National Cemetery, I started with the Nikon 24-70mm lens. Here's the scene when viewed through the 50mm focal length:

I liked the photograph at 50mm. That focal length shows the scene as I saw it with my eyes at the time. Next, I decided to try viewing the same scene with my 500mm lens. The super-telephoto lens does a great job of bringing the tombstones much closer together. And, by bringing the tombstones closer together, it portrays that the cemetery is very crowded.

Both photographs were taken from the same location. By changing focal lengths, the photographs take on an entirely different look!
