The Tokina AT-X is a fish-eye lens that gives the digital photographer a very large 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 opens an entirely new dimension of photography. Unlike other fish-lenses, the AT-X gives a full corner-to-corner image.
The front element of the AT-X has a "water repellent" optical coating on the glass. This 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 glass element to reduce the number of elements in the optical design in order to make the lens more compact, light-weight and faster focusing.
