Tilt Shift Lenses
The term Tilt Shift lens refers to lenses that can change, angle and correct the perspective. These effects occur optically in the lens as the lens elements can be moved and shifted according to the desired effect.
The tilt function, which is accessed by tilting the front of the lens, is used to control the sharpness of the image so that you as a photographer can focus over a larger or smaller area. This can be useful if you intend to create overview or detail images that, with a corrected and narrow focus plane, make the subject appear as thumbnails. The tilt function is also common in advertising and landscape photography, where a large focus plane is often desired.
The shift function in the lens, which is a perspective correction, is made possible by the lens itself moving laterally. This means that you can, for example, photograph taller buildings without falling lines. If you are standing in front of a tall building and are going to photograph it with a more traditional lens, the building will narrow down the higher you aim your camera. With a Tilt Shift lens, you can instead place the camera horizontally and then mechanically shift the lens upwards and thus get the building without the same tapered effect.
