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.
Complementing the operation of the lens, this L-series prime is also distinguished by its optical design that features four Ultra-Low Dispersion elements to significantly reduce color fringing and chromatic aberrations as well as one aspherical element to minimize spherical aberrations and distortion. Individual elements also feature a Subwavelength Coating to suppress flare and ghosting for greater contrast and color neutrality. Additionally, a floating optical system and a rear focus design help to maintain consistent image quality throughout the focusing range, from 9.8" to infinity.
