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 and depth of field control. This tilt-shift lens affords +/- 11mm of shift and +/- 8° of tilt, and both types of movements can be applied independently, and parallel or perpendicular to one another and shift functions can be rotated +/- 90° for applying the movements in distinct directions. Tilt-locking mechanism ensures the lens stays in place while shooting for greater stability. Its Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques. The lens also employs a floating optical system and rear focusing design to maintain image quality throughout the focusing range from 1.3' to infinity. Super Spectra coating has been applied to individual element to reduce flare and ghosting for increased contrast and color accuracy.
