The 12-24mm f/4 AT-X 124AF 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.
