The Tokina AT-X 107 DX is a fish-eye lens that gives the digital photographer an approximate 180° 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. 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 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 (Super-Low Dispersion) glass element to reduce the number of elements (pieces of glass) in the optical design in order to make the lens more compact, light-weight and faster focusing.Note: www.camera.co.idwww.camera.co.id This lens is designed to work with cameras that have an APS-C sized sensor only.A refinement of the focus clutch mechanism has been incorporated in the AT-X 280 AF PRO Nikon and Canon mount, so that now the lens focus ring can be snapped back to the manual focus position at any time, www.camera.co.idfrom any position. This improvement means it is not necessary to change the AF/MF switch (on the body with Nikon or the lens with Canon) every time the lens is changed from auto focus to manual focus mode.
