Tokina AT-X Pro 11-16mm f/2.8 DX II

The Tokina AT-X 116 PRO DX II is an ultra-wide angle lens with a fast f/2.8 aperture for better photography in low-light situations. It's an update to the highly-regarded AT-X 116 PRO DX with revised lens coatings, and the addition of an in-lens focus motor for the Nikon mount version. Tokina's One-Touch Focus Clutch mechanism allows the photographer to switch to manual focus simply by pulling back the focus ring.
