Canon TS-E 17mm f/4L

The Canon TS-E 17mm f/4L offers a broad angle of view combined with intricate perspective and focus manipulation for architectural and interior photography. It features up to ±6.5° tilt for selective focus and ±12mm shift for perspective alteration, with a rotation capability of ±90° for any directional movement. The lens also has a tilt-locking feature for added stability during shooting. It boasts an L-series classification and an optical construction that includes four Ultra-Low Dispersion elements to drastically diminish color discrepancies and aberrations. In conjunction with one aspherical element, distortion and spherical aberrations are also well controlled. To enhance contrast and color fidelity, each element is coated with a Subwavelength Coating to suppress lens flare and ghosting. The floating optical system along with its rear focusing design ensures maintained image sharpness from 9.8" to infinity.
