See my reviews of Sigma DG HSM Art lenses at 20mm, 24mm, 35mm, 50mm.
Unexpectedly, the Sigma 12-24mm f/4 DG HSM Art showed up today.
At about $1599, the Sigma 12-24mm f/4 DG HSM Art might offer performance that might rival Canon’s about $2799 11-24mm f/4L. Or it might fall short—to be seen/tested. But the Sigma lens is available for Nikon or Canon or Sigma SA mounts. As it stands, I’ll be testing it on the Nikon D810.

With 16 elements in 11 groups (same as Canon 11-24/4L) including two elements claimed equivalent to fluorite, the Sigma 12-24mm appears to be a very highly corrected lens offering very low distortion and outstanding performance.
Fit and finish are attractive, just like all its siblings, and more attractive than Nikon and Canon offerings, to my eye.
