Presenting an ultra-wide field of view with advanced perspective and focus control, the TS-E 17mm f/4L is a Canon L-series tilt-shift lens well-suited to architecture and interior photography. Up to +/- 6.5° of tilt is possible, for focus control, and +/- 12mm 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.
