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 authorised Canon Service Facility (modified at owner's expense).

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's optical axis in parallel.
Tilt Movements
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 maximum aperture.
By tilting the centre 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).

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).
