11. Summary

Pros:
  • solid casing,
  • unique parameters,
  • sensational image quality in the frame centre no matter what focal length you employ,
  • sensible image quality on the edge of the APS-C/DX,
  • imperceptible longitudinal chromatic aberration,
  • moderate coma,
  • low astigmatism,
  • slight vignetting for this class of equipment,
  • good price quality and price possibilities ratio.

Cons:

  • dismal AF/MF ring which performs poorly,
  • problems with autofocus,
  • higher distortion level than that of its rivals,
  • performance against bright light could have been better,
  • huge lateralc chromatic aberration.
Already with their 11-16 mm model Tokina raised standards pretty high for its rivals. Now the new model makes the competition even more demanding because the focal range increased to 11-20 mm making the lens more universal without worsening its optical properties. In fact there are categories (like the flares, chromatic aberration or vignetting) where the new lens is noticeable better than the old one. Apart from that it can provide really sharp photos across the whole focal range – a very important feature.

The autofocus slip-up is painful, though. Perhaps the fact that in our test we used quite elderly bodies (the Nikon D7000 and the Canon 50D) contributed to that result; it is possible that the lens attached to a newer camera like the EOS 7D MkII or D7200 will perform better. Still we strongly recommend testing it personally on your own camera, preferably before the purchase.
