The TS-E 17mm f/4L Tilt-Shift Lens from Canon is an ultra-wide-angle manual focus lens for EF mount cameras with a 104º diagonal angle of view on full-frame cameras. It is the widest tilt-shift lens in the Canon lineup and provides tilt-shift functions to control perspective and correct convergence of lines within your frame. It is especially useful in architecture, landscape, and product photography. The optical tilt mechanisms enable precise control of depth of field along with perspective control.

The tilt-shift function on the 17mm f/4 lens allows adjustment of the focal plane by an angle of +/-6.5º and enables parallel shift of the optical axis by +/-12mm. Both tilt and shift can be engaged singly and in combination. The tilt-shift rotation mechanism locks at a right angle and at parallel and clicks at 45º and the lens mount itself can rotate left or right by 90º with click-stop adjustment each 30º.

Being a Canon L-series lens, its optical design and physical structure are optimal. Aspherical and ultra-low dispersion lens elements suppress aberrations and provide sharp delineation. Subwavelength Structure Coating (SWC) reduces ghosting and flare and a truly circular diaphragm results in pleasing out-of-focus backgrounds. The focus ring on the lens provides precise manual focus action and the improved tilt and shift knobs are sturdy and smoothly control the mechanisms.

Features:

TS-E lens is compatible with all Canon EOS cameras

The 104° diagonal angle of view (without tilt or shift) is ideal for ultra-wide-angle applications including architecture, landscape and product photography.

A wide image circle of 67.2mm is 50% greater than the 35mm/full frame film area.

High precision glass (18 elements/12 groups) for low distortion and high resolution to the edge of the image.

The tilt and shift mechanism rotates +/-90°, allowing a shift in any direction and the tilt mechanism independently rotates +/-90°, allowing tilt in any direction relative to the shift.

One aspherical and four UD lens elements minimize chromatic aberration.

A floating internal focus mechanism delivers high image quality throughout the focus range.

Sub-wavelength structure coatings minimize ghosting and flare

A truly circular aperture creates pleasing out-of-focus background areas.
