The Tilt movement alters the angle of the plane of focus between the lens and film plane, and shift movements move the lens' optical axis in parallel.

Canon TS-E lenses are unique in their ability to provide both tilt and shift movements relative to the film plane (or CCD) making them ideal for all kinds of scientific, architectural, creative and advertising photography. With a Canon TS-E lens the Tilt movement makes it possible to achieve incredible focus and defocus effects independent of aperture setting and Shift movement allows you to correct the perspective of images otherwise distorted by the position of the photographer relative to the subject.
