Item Description
Features:
Tokina's exclusive One-touch Focus Clutch Mechanism allows photographers to
switch between AF and MF simply by snapping the focus ring forward for AF and
back toward the lens mount for manual focusing. Additionally the mechanics have
been designed for better seals around moving parts making the lens more
water-resistant than lenses of the past. The lens is also designed to stand up
to the rigors of daily use by photographers in a wide variety of shooting
conditions and environments. (Lens is only water-resistant, NOT water-proof and
should not be submerged in water without protection.)
This compact wide-angle zoom has a bright constant f/4 aperture make
viewing and auto focus possible in lower light situations but still maintaining
a reasonable size and weight.
Two Super-Low Dispersion glass elements and one aspheric glass allow the
proprietary optical design to achieve excellent contrast and sharpness as well
as controlling chromatic aberration.
