For the professional, a 16-28mm f/2.8 lens is almost a necessity, and this new Tokina AT-X 16-28mm F2.8 Pro FX Lens for Canon fills the bill very nicely. This super wide-angle zoom has 15 elements in 13 groups, using aspherical and SD super-low dispersion glass elements to reduce chromatic aberration and give maximum resolution. The silent DC motor allows the lens to focus quickly and quietly and works with a GMR magnetic AF sensor to increase AF speed even more.
An exclusive One-Touch Focus Clutch mechanism allows switching quickly between auto focus and manual focus by snapping the focus ring forward for AF and back toward the camera for manual focus. And, it’s possible to buy this lens without applying for a mortgage first.
- NEW Silent DC Motor With GMR Sensor
- 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.
- Aspherical and Super-Low Dispersion Glass Elements
- A new, 56mm-diameter, large size aspherical glass element is incorporated into the front lens group, while there are two more aspherical elements in the rear group. Three SD super-low dispersion glass elements are also incorporated throughout the optical design to reduce chromatic aberration, give maximum resolution, more even brightness and distortion correction.
