The Canon TS-E 17 mm f/ 4 L
Canon extended its 1991 lineup of lenses with a 24x45x90 mm tilt and shift mechanism and produced the Canon TS-E 17mm f/4L ultra wide-anglelens. A 17 mm focal length provides the widest angle of view of all tilt-shift lenses available today.
Due to high-precision aspherical front elements, distortions, characteristic of wide-angle lenses, are minimized even on the frame edges. The optic scheme of the TS-E 17mm lens includes 4 SLD elements for minimizing chromatic aberrations and optimizing focusing mechanisms. In addition to all its merits, the TS-E 17mm f/4L has a special antiglare SWC coating for minimizing flare caused by internal reflections and thus taking fine and sharp pictures.
The TS-E 17mm f/4L features a new function: independent tilting and shifting. It is especially effective for perspective photography requiring a special arrangement and focal plane. Coupled with an unexcelled image quality across the frame, it makes the lens ideal for architecture and landscape photography.
The specifications of the Canon TS-E 17mm f/4L:
tilt-shift lens is compatible with all Canon EOS cameras;
tilt ± 6.5° mm, shift ±12 mm;
+/-90° tilt-shift rotation mechanism makes it possible to shift the lens in any direction;
+/-90° tilt-shift rotation mechanism makes it possible to tilt the lens in any direction relative to the shift;
SLD aspherical lenses minimizes chromatic aberrations;
SWS and Super Spectra coatings combat flare and spurious reflections;
circular aperture may be used for such artistic devices as background blurring;
TS-E 17mm f/4L is equipped with a floating mechanism of internal focusing providing a high-quality image throughout the entire focus range.
