Tokina AT-X 116 PRO DX II Canon and Nikon mount lens reviews: popular high-speed zoom revisedBy Kevin Carter - Friday July 12 2013 Lens Review
Tokina AT-X PRO SD 11-16 F2.8 IF DX II Nikon Versus Nikon AF-S NIKKOR 14-24mm f/2.8G ED mounted on Nikon D7000:
Comparing the Nikon mount model to its closest rival, the full-frame Nikon AF-S Nikkor 14-24mm f/2.8G ED the Tokina is very close in performance. It can’t quite match it for Sharpness nor Distortion and CA remains a concern but overall the Tokina remains impressive (and a viable option given the difference in price and portability).
Tokina AT-X PRO SD 11-16 F2.8 IF DX II Canon Versus Sigma 10-20mm F3.5 EX DC HSM Canon mounted on Canon EOS 7D:
In our second comparison, we’ve selected the Sigma 10-20mm f/3.5 EX DC HSM to contrast the performance (as it’s also available in other mounts, not just Nikon). Overall uniformity of the Sigma is better than the Tokina but it can’t quite match it on Sharpness, Transmission or Vignetting. However, it has far lower levels of Chromatic Aberration and comes just slightly ahead in our DxOMark Score. It’s also around $200 cheaper at $479.
