Product Description Designed for full-frame cameras, the Tokina AT-X 17-35 mm F/4 gives photographers a wide-angle option. With a focal length of 17 mm at the wide side the lens yields a spectacular 103.9 degree field of view which is ideal for shooting in tight situations or for taking in wide expanses of space. This compact wide-angle zoom has a bright constant F/4 aperture make viewing and auto focus possible in lower light situations but still maintaining a reasonable size and weight. Two super-low dispersion glass elements and one aspheric glass allow the proprietary optical design to achieve higher contrast and sharpness as well as controlling chromatic aberration. Tokina’s One-touch Focus Clutch mechanism allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the lens mount for manual focusing. Additionally the mechanics have been designed for better seals around moving parts making the lens more water-resistant* than lenses of the past. The lens is also designed to stand up to the challenges of daily use by photographers in a wide variety of shooting conditions. (*The AT-X 17-35 is water-resistant, not water-proof and is not designed to be submerged or used unprotected in heavy rain.) Box Contains Tokina Nikon 17-35 Manual Soft Pouch
