Using TiltShift Lenses
Referred to as TS-E lenses, tilt/shift lenses enable you to alter the angle of the plane of focus between the lens and sensor plane to provide a broad depth of field even at wide apertures and to correct or alter perspective at almost any angle. TS-E lenses correct perspective distortion and control focusing range and are a staple in architectural photography.
Tilt movements allow you to bring an entire scene into focus, even at maximum apertures. By tilting the lens barrel, you can adjust the lens so that the plane of focus is uniform, thus changing the normally perpendicular relationship between the lens's optical axis and the camera's focal plane. Alternately, reversing the tilt has the opposite effect, greatly reducing the range of focusing.
Shift movements avoid the trapezoidal effect that results from using wide-angle lenses and pointing the camera up to take a picture of a building, for example. Keeping the camera's focal plane parallel to the surface of a wall and then shifting the TS-E lens to raise the lens results in the building's perpendicular lines maintaining a rectangular appearance.
TS-E lenses revolve within a range of +/- 90°, making horizontal shift possible and even useful in shooting a series of panoramic images.
All Canon TS-E lenses are manual focus only. These lenses, depending on the focal length, are excellent for architectural, interior, merchandise, nature, food, and any photographic composition that presents special focusing considerations.
