About the Tokina Lens 12-24mm F4.0 DXII Nikon

The Tokina 12-24mm f/4 AT-X 124 AF Pro DX lens is exclusively designed for use with Digital SLR cameras, and provides a super wide-angle zoom range, ideal for the tightest of interiors, as well as for dramatic landscape photography.

This lens features the exclusive &quotFocus Clutch Mechanism&quot, a signature of the Tokina PRO series lenses which provides a faster, smoother autofocus operation with a smooth manual focus action not normally found in autofocus lenses.

Two Aspherical elements are incorporated in the lens design, to correct for spherical aberrations. It also incorporates internal focusing to prevent deterioration of the optical quality at close distances and to eliminate rotation of the front barrel during focusing.

Note: Equivalent focal length in 35mm terms when used on a digital camera is 18-36mm.

Note! DX lenses are NOT recommended for use with &quotfull-frame&quot FX digital or 35mm film SLR cameras. AF not supported by D5000, D40 and D60 cameras.
