For Advanced Photo Work

With a Canon TS-E lens, you can control the angle of the plane of focus and the picture’s perspective. The effects of large-format camera movements can be obtained with TS-E lenses for EOS cameras. Although manual focusing is required, automatic aperture control enables autoexposure and autoexposure bracketing. The tilt and shift axes intersect at a 90˚ angle. They can be made parallel at an authorized Canon Service Facility (modified at owner’s expense).

TS - E LENSES

TS-E Lens Movements

TS-E lenses are capable of tilt and shift movements which greatly expand picture-taking possibilities. Tilt movements alter the angle of the plane of focus between the lens and film plane, and shift movements move the lens’ optical axis in parallel.

Tilt Movements

The widest tilt-shift lens in the Canon system, and a marvelous problem- solver for architecture, scenics, and many other applications calling for a wide-angle perspective. With floating optics, it’s sharp from infinity down to 1 ft. (0.3m), and it uses a ground and polished Aspherical front element to assure excellent quality. Like all the TS-E lenses, it has a fully automatic diaphragm, so there’s never a risk of forgetting to stop the lens down.

The normal lens in the TS-E system, and an excellent choice for product shooting and other applications calling for a natural perspective. It allows up to 11mm of shift off-center, and even more impressive, tilting of the front standard up to 8° to modify the plane of focus. Among the TS-E 45mm f/2.8’s optical highlights are a floating optical system (focusing down to 1.3 ft/0.4m), and a precise rear-group focusing system.

If you want to bring the entire length of the hedge into focus, you could use a wide-angle lens and a small aperture to obtain a wide depth of field (Photo 1-a). With tilt movements, you can achieve this wide depth of field even at the max- imum aperture. By tilting the center of the TS-E lens barrel, you can tilt the lens so that the plane of focus is uniform on the film plane (Photo 1-b).

TS-E 90mm f/2.8

Telephoto perspective, f/2.8 speed, and full tilt and shift movements in a compact, professional package. Impressively sharp, its ability to alter the plane of focus can provide a “look” that previously required a view camera to achieve. Pros have found it a great option for portraits, products and even fashion work. At its closest focus distance (1.6 ft/0.5m), it gives magnifications of about 1/3 life-size.

Shift Movements

Normally, when you point your camera up at a tall building, the building will look slimmer toward the top. It becomes trapezoidal (Photo 2-a). This perspective effect is more pronounced with shorter lens focal lengths, distorting the building even more. By altering the parallel position between the lens and the film plane with the TS-E lens, this perspective effect can be corrected. With the camera’s film plane set parallel to the building, shifting the lens upward will obtain a more rectangular-looking building (Photo 2-b).
