  • solid and sealed barrel,
  • excellent image quality in frame centre,
  • good image quality on the edge of APS-C,
  • sensible image quality on the edge of full frame,
  • lack of problems with longitudinal chromatic aberration,
  • imperceptible lateral chromatic aberration,
  • lack of problems with distortion on the smaller detector,
  • slight astigmatism,
  • low vignetting on the APS-C/DX sensor,
  • quick, silent, and accurate autofocus,
  • very good performance against bright light.


  • distinct distortion on full frame which, additionally, at the shortest focal lengths shows some moustache deformations,
  • a tad too pronounced spherical aberration,
  • high vignetting on full frame.
In the summary of our test we praised a lot the Sigma A 14-24 mm f/2.8 DG HSM. The Sigma A 14-24 mm f/2.8 DG DN reached very similar results in practically all testing categories so it would be difficult to criticize it here. We feel it deserves our praise especially that it is an instrument noticeably smaller and physically ligher than its reflex camera equivalent and yet it managed to ensure you even a tad better resolution on the edge of full frame.

It would be difficult to demand anything more from a lens with such a wide angle of view and a good, fixed-focal f/2.8 aperture fastness. You get high image quality in the frame centre right from the maximum relative aperture and no weak points even in the very demanding edges of full frame. If you add to that an excellent performance against bright light, a sensational correction of chromatic aberration and a fast, silent, and accurate autofocus, the overall image is really outstanding. Two biggest slip-ups, distortion and vignetting, are at the same time easily corrected by software (but, of course, you have to pay for every of such corrections) so you can forgive them more willingly.

Finally the matter of price. The Sigma A 14-24 mm f/2.8 DG DN can hardly be called cheap – you have to pay around $1400 for it. Two facts might make that spending more bearable. Firstly, when you compare this amount of money to prices of other mirrorless full frame devices you can find out the company didn't go over the top. Secondly, Sigma have resisted the temptation of raising the prices when moving from reflex camera constructions to mirrorless models because the price tag of the new Sigma is basically the same as the price of its reflex camera equivalent.
