Features
Overview: The Canon TS-E90mm f/2.8 tilt-shift lens is a
special accessory lens for Canon EOS cameras. The tilt-shift mechanism enables
photographers to control the depth of field and the area photographed, and to
correct image distortion that occur with conventional lenses. The lens can be
tilted up to +/-8° and shifted up to +/-11mm. It is recommended that you use the lens
on an EOS camera with 100% viewfinder visibility, and use a laser matte with
grid focusing screen. You should also place the camera on a tripod.
Lens Mount: The TS-E90mm has a standard Canon EF-mount, and
is compatible with EOS DSLR cameras.
Focusing: The tilt-shift lens can only be used in a manual
focusing mode. Shots cannot be taken using auto-focus. The distance scale is
only valid when the tilt scale is set to the "0" position.
Exposure: Shots can be taken using AE (automatic exposure)
only when the tilt and shift scales are set to the "0" position. It is
recommended that you use the same exposure values as a guide to set them
manually when using the tilt and/or shift functions.
Tilt Function: Normally, the focusing and imaging planes are
parallel. Tilting inclines the lens relative to the image plane, putting it at
an angle to the image plane. Tilting allows you to keep all of the subject in
focus, even when there is insufficient depth of field. Tilted in the opposite
direction, the lens lets you focus only on a specific part of the subject.
Shift Function: The shift function moves the optical axis of
the lens in parallel off the center of the imaging plane. Photographing a
building with a normal lens can sometime result in an image of the building
leaning backwards. This is due to the camera not being parallel to the building.
Using the shift function and placing the camera parallel to the building, the
building to appear natural in the image. Also, if you are shooting a reflective
subject, such as a mirror on a wall, your reflection can appear in the image. By
moving the camera and shifting the lens, you can keep the camera out of the
shot, without having to change the shot composition.
Rotation: The lens also has a rotation function that enables
you to change the direction of tilt or shift by rotating the tilt-shift
mechanism. The mechanism can be rotated up to 90° in either direction.
Lens Hood: The TS-E90mm lens comes with the EW-79BII lens
hood. The lens hood keeps unwanted light out of the lens, and protects the lens
from rain, snow, and dust.
