reviews
- https://www.dxomark.com/Reviews/Sigma-24-35mm-F2-DG-HSM-Art-Nikon-mount-review-Performance-redefined
- very good sharpness, best at 24mm f/2 - the best ranked zoom lens tested
- T2.2
- 0.4% distortion
- 2.1EV vignetting
-
- surprisingly as sharp as the Sigma 24mm and 34mm f/1.4 ART primes and even surpasses the optical performance of both in the APS-C/DX-corner lagging a bit only in the FF/FX-corner at 35mm
- quite a smooth Bokeh and relatively little longitudinal CA and moderate coma at f2.0
- AF needed fine-tuning in Sigma’s USB-dock
