Tokina AT-X 10-17mm f/3.5-4.5 DX Fisheye

Manufacturer's Description:

"The new Tokina AT-X 107 DX is a full-frame fish-eye lens that gives the photographer a 180 degree field of view with dramatic curvature of field or "fish-eye" effect. With this lens an entire view or vista can be captured, wider than the human eye can see. the AT-X 107 opens an entirely new dimension of photography.

The front element of the AT-X 107 DX has a newly formulated WP or "Water Proof" optical coating on the glass. This new coating makes marks such as spots left by water or finger prints much easier to clean than standard multi-coating.

The rear optical group of the lens contains 1 SD m(Super-Low Dispersion) glass element to reduce the number of elements in the optical design in order to make the lens more compact, light-weight and faster focussing."
