Sigma 14-24mm f2.8 DG DN Art review - Verdict

Verdict

The Sigma 14-24mm f2.8 DG DN Art is a well-designed ultra-wide angle zoom lens complementing Sigma’s 24-70mm f2.8 DG DN Art for ultra-wide coverage. Its optical construction takes advantage of the shorter flange distance of mirrorless cameras and is a further improvement over Sigma’s DSLR design from 2018.

It performed very well regarding contrast, resolution, colour aberrations, and coma, producing very good image quality on a demanding 42MP Sony A7 R II body. And while the lens may not allow for standard front filters Sigma added a slot for gel filters at the rear. Its features also includes thorough weather sealing, a focus-lock button and the unique option to get the lens mount swapped (at a cost) between Sony’s E-mount and Leica’s L-mount.

What’s not to like? Well, extreme wide-angle fans may be disappointed the lens does not go wider than 14mm. Sony sets the expectation here with its 12-24mm f2.8 GM zoom. There is also a slight loss of contrast at 24mm in the center from haloing/blooming. And autofocus is on the slow side.

Let’s have a closer look at how the Sigma 14-24mm f2.8 DG DN Art compares to some alternatives.

Compared to Sony FE 12-24mm f4.0 G

I’ve not yet written up my results for the Sony FE 12-24mm f4.0 G but I’ve already run all the usual tests. From that I can say the Sony is a good lens optically with a very sharp center. Plus it offers an 8 degree wider angle of view on the short end and is over 200g lighter and also smaller than the Sigma. But it is one stop less bright with its f4.0 focal ratio and it falls back behind the Sigma with regard to Bokeh, corner sharpness, coma, and resilience against flare and glare – although not by a large margin. So in the end the question is: Do you value an 8 degrees wider angle of view of the Sony FE 12-24mm f4.0 G higher than the constant f2.8 focal ratio and better optics of the Sigma 14-24mm f2.8 DG DN Art?

Compared to Sigma 14-24mm f2.8 HSM Art

The Sigma 14-24mm f2.8 DG HSM Art is one of the best ultra-wide angle zoom lenses for Canon and Nikon DSLRs, and is also an option for Sony mirrorless owners via an adapter. It can produce very sharp and undistorted images but you have to stop down on the short end to reduce the effect of astigmatism and field curvature. Compared to its younger sibling designed specifically for the shorter flange distance of mirrorless cameras the Sigma HSM is a bigger and much heavier lens and lacks the features of a focus-lock button and a rear filter holder. Optically the Sigma HSM is slightly behind the Sigma DN in almost every aspect – but continues to be a very good lens nonetheless.

Compared to Nikon Z 14-24mm f2.8 S

Strictly speaking, the Nikon Z 14-24mm f2.8 S is not an alternative as Sigma currently offers its lens in E-mount and L-mount only. But that’ll probably change in the future. Nikon’s new ultra-wide zoom lens is clearly the rightful successor to the legendary Nikon AF-S 14-24mm f2.8G as it is optically better in every aspect than the F-Nikkor from 2007 except for Bokeh. But compared to the newer design of the Sigma 14-24mm f2.8 DG DN Art differences in optical performance become minimal and both lenses are mostly neck-and-neck. Differences can be seen in harsh contra-light situations where the Nikon has the more effective coating and in Bokeh where the Sigma shows less double contours. The Nikon also focuses a lot faster than the Sigma but that is not exactly an apples-to-apples comparison when tested on two different cameras. The major difference between both lenses in the end is price: The Nikon is twice as expensive as the Sigma and although the Z-Nikkor can use standard filters and features a very useful multi-function ring plus a nice OLED display this makes the Sigma 14-24mm f2.8 DG DN Art look like a real bargain with a very good price/performance ratio.

Sigma 14-24mm f2.8 DG DN Art final verdict

The Sigma 14-24mm f2.8 DG DN Art demonstrates the virtues of optical designs which are optimized for the shorter flange distances of mirrorless cameras: it is optically better in almost every aspect than its DSLR sibling and loses more than 300g in weight. Its optical performance is almost flawless with a slight loss of contrast at 24mm, f2.8 in the center from haloing/blooming. But that doesn’t prevent the lens coming Highly Recommended! Let’s hope that Sigma soon is able to offer their new lens with Nikon Z-mount and Canon RF-mount too.

Good points:

  • Very good resolution and contrast.
  • Almost no longitudinal colour aberrations or coma.
  • Very good resistance against flare, glare, and ghosting.
  • Low vignetting and minimal distortions (through lens profile).
  • Constant f2.8 focal ratio.
  • Extensive weather sealing plus fluorine coating against moist and dust.
  • Very little focus breathing.
  • Zooming does not change focus.
  • Can use gel filters.

Bad points:

  • Cannot use standard filters.
  • Autofocus could be faster.
