Item Description
This new
Tokina lens is the first in a new generation of full frame (FX) lenses designed
for professional digital SLR cameras like the Canon EOS 5D Mark II and the Nikon
D700 and D3x. 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 then previous generations. The DC motor coupled with a
new GMR magnetic AF sensor work together to increase AF Speed.
Ashperical 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.
