If a photographer really wants to cover a fairly large area but, desires an interesting and exciting image, panos come into play. Shooting a multi-shot pano with a longer focal length lens produces exciting and interesting, especially if the camera is in the vertical position is a great way to shoot a landscape. See:

Panos are not particularly difficult, especially single string panos. You don't need specialty equipment and often, a pano can be shot hand-held as with this shot of the Beijing "Birdcage" Olympic Venue. I did not have the time to get closer and if I shot with a UWA lens, I would have achieved an image with a lot of uninteresting foreground and sky and a small Birdcage.
