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 "Focus Clutch Mechanism", 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 "full-frame" FX digital or
35mm film SLR cameras. AF not supported by D40 and D60 cameras.
