AT-X 16-28 PRO FX
FULL FRAME WIDE ZOOM
This new Tokina lens is the first in a new generation of full frame (FX) lenses
designed for professional digital SLR cameras. The 16-28 zoom range
gives the professional photographer a super-wide angle of view to get
close to subject for dramatic effect or to take in entire scenes.
NEW Silent DC Motor with GMR Senor
The 16-28 f/2.8 uses a newly developed silent DC motor that allows the lens
to focus faster and more quietly than previous generations. The DC motor
coupled with a new GMR sensor works together to increase AF speed.
Aspherical and Super-low Dispersion Glass Elements
A new, 56mm in diameter, large sizes aspherical glass element is
incorporated into the front lens group, while there are 2 more aspherical
elements in the rear group. 3 SD super-low dispersion glass elements are
also incorporated through-out the optical design to reduce chromatic
aberration, give maximum resolution, more even brightness and distortion
correction.
One-Touch Focus Clutch
Tokina’s exclusive One-touch Focus Clutch Mechanism allows the
photographer to switch between AF and MF simply by snapping the focus
ring forward for AF and back toward the camera to focus manually. There
is no need to change the AF/MF switch on Nikon camera bodies and
there is no second AF/MF switch on the lens for Canon, everything is
accomplished by the focus ring.
