11. Summary

Pros:
  • unique parameters,
  • solid and stylish casing,
  • sensational image quality in the frame centre,
  • excellent resolution on the edge of the APS-C/DX,
  • better resolution on the edge of full frame than that of many fixed focus lenses,
  • moderate longitudinal chromatic aberration,
  • slight lateral chromatic aberration,
  • proper correction of spherical aberration,
  • low distortion in the 28–35 mm range,
  • slight astigmatism,
  • lack of problems with vignetting on the APS-C/DX sensor,
  • silent, accurate and quite fast autofocus.

Cons:

  • noticeable distortion on full frame at 24 mm,
  • a bit too high coma,
  • very high vignetting across the whole focal range.

“Three ‘primes’ in one lens” – in the case of the tested Sigma such a statement is not just an empty marketing slogan, quite the opposite in fact. When it comes to the resolution the Sigma 24-35 mm is not worse than any brand name fixed focus f/1.8 and f/2.0 device. Sometimes it fares even better than those. If you are not afraid of its dimensions and significant weight and you need a universal tool with a possibility to change the focal length even in such a narrow range it is definitely a lens you should get interested in.

Of course you might start wondering whether it wouldn’t be better if Sigma presented a 24-50 mm or a 28-50 mm instrument, with a variable aperture ranging from f/2.0 to f/2.8 but it is perhaps taking too much for granted. Sigma decided to produce the 24-35 mm lens and took proper care of every single focal length; we have to admit the results are splendid. If you take into account the fact that there is no similar device in any other producer’s line-up, even the most finicky grumbler might stop complaining.
