Canon TS-E 17mm f/4L Tilt-Shift Lens
Overview
The widest tilt-shift lens in Canon's
lineup, the new TS-E 17mm f/4L lens expands shooting possibilities
exponentially on EOS Digital cameras. Designed with UD glass to minimize and
compensate for chromatic aberrations, with a specially coated aspherical element
for the highest possible glare-free image quality, this tilt-shift lens offers
a diagonal angle of view of 104° on a full-frame SLR camera.
New TS rotation lets users freely combine tilting and shifting within the range of +/- 90° in the direction of movement. The lens also has an improved tilt & shift knob with an enhanced range of movement of up to +/- 6.5° and 12mm respectively, with a revolving function for better operability. It uses a circular aperture for beautiful out-of-focus areas and has an SWC lens coating to control ghosting and flare to a far greater degree than with earlier coating technologies.
