A shift lens corrects for apparent distortions in perspective caused by the film plane not being parallel to the to the subject plane. The usual example is photographing a tall building and filling the frame by tilting the camera upward. The sides of the building will appear to converge toward the top. A shift lens allows you to keep the film plane vertical (parallel to the building) by allowing you to shift the lens vertically to fill the frame. This keeps the sides from appearing to converge.
The lens is useful for architectural photography. I've used it for photographing tall pine forests.

But when we disarmed they sold us, and delivered us, bound, to our foe. And the gods of the copybook headings said, 'Stick to the devil you know.'
