The new Tokina AT-X 116 PRO DX is an ultra-wide angle lens with a fast f/2.8 aperture for better photography in low-light situations. Many photojournalists consider having an f/2.8 aperture a must for any lens in their camera bag.
Based on the award-winning optical design of the AT-X 124 PRO DX (12-24mm f/4) lens, the new AT-X 116 PRO DX has a slightly shorter zoom range to maintain optical quality at wide apertures.
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 cameras** and there is no second AF/MF switch on the lens for Canon, everything is accomplished by the focus ring.
It’s better than the more expensive (and longer zoom range) Nikkor 12-24mm.
If you shoot Canon, get the Canon 10-22mm, since it doesn’t cost much more and has a much wider and longer zoom range. I have not compared its sharpness, however the Canon’s distortion control is superior.
- very solid barrel,
- reasonable dimensions for the optical parameters offered,
- excellent center-of-the-frame quality,
- good image quality in the corners,
- quite well-controlled astigmatism,
- sufficiently low vignetting for this grade of equipment,
- good price/quality ratio,
- high levels of chromatic aberration throughout the range,
- too high coma,
- uneven performance against the light,
- mediocre AF performance.
The Tokina AF 11-16mm f/2.8 AT-X Pro DX is currently the best ultra-wide angle zoom lens for Canon EOS APS-C DSLRs (01 May 2008). The resolution is impressively high throughout the zoom range (albeit a short one) and across the image field.
