Tilt-shift lenses have a few specialized uses. For example, they can alter the plane of focus by “tilting.” This can be used to create a sharp focus along something that is not perpendicular to the film/sensor, or to create an interesting depth of field that can’t be achieved with a normal lens. Depending on the subject, this crazy DOF can make a life-size scene appear to be a miniature–pretty cool! The other function of a tilt-shift lens is, you guessed it, “shifting.” This is most commonly used in architectural photography to prevent converging-lines distortion.
