Mixing a short telephoto field of view with perspective- and depth of field control, the TS-E 90mm f/2.8 from Canon is a tilt-shift lens well-suited to producing well-corrected imagery with a slightly compressed 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 Gaussian-type optical design to maintain image quality throughout the aperture range and a Super Spectra coating has been applied to individual element to reduce flare and ghosting for increased contrast and color accuracy. Perspective control, 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. Additionally, the tilt 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. Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions. Gaussian-type optical system affords a high degree of clarity throughout the aperture range and, when paired with the rounded 8-blade diaphragm, contributes to a smooth bokeh quality. Minimum focusing distance of 1.6' and a maximum magnification of 1:3.4 makes this lens suitable for working with close-up subjects.
