The Canon TS-E 17mm f/4L lens is the flagship offering in Canon's Tilt Shift line, a line they promote as expanding photographic possibilities. Tilt movements allow you to capture a wide depth of field while keeping the entire subject in focus, while shift movements correct the trapezoidal effect which sometimes distorts pictures of tall objects. The TS-E 17mm f/4L is the widest tilt-shift lens in Canon's lineup. The Canon TS-E 17mm f/4L lens has all the same features as the TS-E 24mm f/3.5L II lens, but with a shorter focal length (17mm as opposed to 24mm), higher angle of view (104 degrees as opposed to 84 degrees), lesser degree of maximum close-up magnification (0.14x as opposed to 0.34x), more elements (18/12 as opposed to 16/11) and higher aperture (f/4 as opposed to f/3.5). The TS-E 17mm f/4L also has a floating focusing system, whereas the TS-E 24mm f/3.5L II does not. The UD glass design of this lens minimizes and corrects abberations. The coated aspherical element gives the highest possible glare-free image quality. The circular aperture helps to create more striking out-of-focus areas. Canon promotes their SWC (SubWavelength structure Coating) lens coating as controlling ghosting and flare to a greater degree than previous lens coating technologies. Cannon recommends using the TS-E 17mm f/4L lens with EOS Digital cameras.
