The Tokina AT-X 107 DX, For Nikon is a fish-eye lens that gives the digital photographer an approximate 180 Deg field of view with dramatic curvature of field or fish-eye effect. With this lens an entire view or vista may also be captured, wider than the human eye can see. The AT-X 107 opens an entirely new dimension of photography. Unlike other fish-lenses, the AT-X 107 DX gives a full corner-to-corner image. The front element of the AT-X 107 DX has a newly formulated WP or AgWater ProofAh optical coating at 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 incorporates 1 SD (Super-Low Dispersion) glass element to reduce the Choice of elements (pieces of glass) within the optical design in an effort to make the lens more compact, light-weight and faster focusing.Note: This lens is designed to work with cameras that have an APS-C sized sensor only.

This lens enables the shooting of full-frame fisheye images with a 180° angle of view and a focal length of 10mm.
Employing ED (Extra-low Dispersion) glass, this lens effectively compensates to triumph over chromatic aberration all through the image.
The image circle of the lens has been created to match the smaller image recording area of digital SLR cameras.
WP (Water Proof) coating made of a special fluoride compound has been applied to the front surface of the new lens
An internal focal point system allows photographers to focal point from as close as approx. 1″ (approx. 2.5 cm), giving them the power to fill the entire frame
