11. Summary

Pros:
  • solid and stylish casing,
  • brilliant image quality in the frame centre,
  • sensational image quality on the edge of APS-C,
  • very good image quality on the edge of full frame,
  • lack of noticeable problems with spherical aberration,
  • moderate longitudinal chromatic aberration,
  • imperceptible lateral chromatic aberration,
  • practically zero distortion level,
  • slight coma,
  • negligible astigmatism,
  • low vignetting on APS-C/DX,
  • silent and accurate autofocus.

Cons:

  • too high vignetting on full frame.

I imagine Zeiss must gnash their collective teeth quite strongly. They invented the Otus series which was supposed to prove that, for a quite astronomical price, you can produce an optically outstanding lens practically without any flaws. Meanwhile Sigma presented their 85 mm device which is not only able to win a duel with the Otus 1.4/85 in the most important categories but also breaks the resolution record of the Otus 1.4/28 on the sensor of the Canon EOS 5D Mark III. Mind you it is over three times cheaper. Nothing to add I suppose – a fully deserved Lenstip Editor’s Choice award.
