Overview
The widest tilt-shift lens in Canon's lineup, the new TS-E
17mm f/4L lens expands shooting possibilities exponentially on EOS Digital cameras.
Designed with UD glass to minimize and compensate for chromatic aberrations,
with a specially coated aspherical element for the highest possible glare-free
image quality, this tilt-shift lens offers a diagonal angle of view of 104° on
a full-frame SLR camera.
- New TS rotation lets users freely combine tilting and
shifting within the range of +/- 90° in the direction of movement. The lens
also has an improved tilt & shift knob with an enhanced range of movement
of up to +/- 6.5° and 12mm respectively, with a revolving function for better
operability. It uses a circular aperture for beautiful out-of-focus areas and
has an SWC lens coating to control ghosting and flare to a far greater degree
than with earlier coating technologies.
Features:
- Aspherical and UD lens elements result in outstanding image delineation
- SWC (Subwavelength Structure Coating) dramatically reduces ghosting and flare caused by light entering at an acute angle
- The lens can be tilted up to +/-6.51° and shifted up to +/-12mm
- The tilt and shift functions can be used singly or in combination. The tilt and shift can switch from right angle to parallel using the TS rotation feature
- The lens can be rotated to change the tilt or shift direction
- A truly round aperture hole results in a nicer background blur
Canon's TS-E lenses are tilt-shift lenses designed for EOS cameras. The tilt-shift mechanism enables photographers to control the depth of field and the area photographed and to correct image distortion,making it possible t take sophisticated pictures that cannot be shot using a conventional lens

Modulation Transfer Function or "MTF" is a measurement of the optical performance potential of a lens.
On EOS cameras with a built-in flash , some partial restrictions may apply to the shift and rotation functions

About the Shift Knob Cap
- Shifting will be easier if the supplied shift knob cap is mounted. However , for EOS cameras with built-in flash, the cap will come in contact with the camera during the lens mounting/detaching or during shift/rotation operation. The shift knob cap is recommended for use with EOS-1, EOS-1D,EOS1Ds and EOS 5D series.
- Remove the shift knob screw
- Mount the cap by squeezing it into the shift knob and then fix it using the supplied screw. To remove the cap, remove the screw and pull out the cap
Mounting /Removing the Lens Cap
- Removing - To remove the cap, hold down the button on the side and turn the cap in the direction of the arrow until the position mark on the cap aligns with the red dot.
- Attaching - To attach the cap, align the cap's attachment position mark with the red dot on the front of the lens, then turn the cap as shown by the arrow until the lens' red dot is aligned with the cap's stop position mark
Tilt Function
- Tilting inclines the lens relative to the image plane. When the tilt scale is set to the "0" position, the focusing and imaging planes are parallel. However,tilting puts the focusing plane at an angle to the imaging plane
- To shoot so that all of an extensive subject is in focus, you must normally use a small aperture to obtain a large depth of field. But tilting allows you to keep all of the subject in focus even when there is insufficient depth of field
- By Tilting in the opposite direction , you can focus on a specific part of the subject
Using Tilt
- To keep the tilt scale locked in the "0" position ,slide the tilt lock button in the direction of "LOCK", then turn the tilt lock knob in the direction of the arrow
- Slide the tilt-lock button in the direction of arrow A . Loosen the tilt lock knob by turning it in the direction of arrow B
- Turn the tilt knob to adjust the amount of tilt. Focus the shot by turning the focusing ring
- Turn the tilt lock knob in the direction of the arrow to lock the amount of tilt for the shot
Shift Function
- Shifting moves the optical axis of the lens in parallel off the center of the imaging plane. Shift can be used to good effect in the situations below.
- If you photograph a subject such as building with a normal lens, the top of the building tapers way. But by placing the camera parallel to the building and shifting the lens, you can correct this tapering effect.
- When you are shooting a reflective subject, you can move the camera to a position where the camera does not appear in the shot and then use shift to take the picture. This lets you keep the camera out of the shot without having to change the shot composition.
Using Shift
- Loosen the shift lock knob by turning it in the direction of the arrow
- Turn the shift knob to adjust the amount of shift. Focus the shot by turning the focusing ring
- Turn the shift lock knob in the direction of the arrow to lock the amount of shift for the shot
