Canon, TS-E 45mm f/2.8 Tilt-Shift Lens (EF)

Mixing a normal field of view with perspective and depth of field control, the TS-E 45mm f/2.8 from Canon is a tilt-shift lens well-suited to producing well-corrected imagery with a natural perspective. 

Up to +/- 8° of tilt is possible, for focus control, and +/- 11mm of shift, to adjust perspective and composition. The tilt-shift mechanism can be rotated +/- 90° for applying movements in any direction, and a tilt-locking mechanism can be used while shooting for greater stability.

The lens also employs a floating optical system and rear focusing design to maintain image quality throughout the focusing range and a Super Spectra coating has been applied to individual elements to reduce flare and ghosting for increased contrast and color accuracy.
