Wideangle Zoom Lens for

Full Frame DSLR Cameras

AF16-28mm f/2.8

TO FIT CANON • NIKON-D

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.
