The Sigma 85mm f1.4 DG DN Art competes directly with Sony’s well-received 85mm f1.4 G Master. Both lenses share an identical focal length and maximum constant aperture. There are other similarities, too: both feature an 11-bladed circular aperture, weather sealing, a customizable focus hold button, a de-clickable aperture ring, and a dedicated focus mode switch. The Sigma also includes an aperture ring lock that the Sony lacks. Sigma’s managed to deliver the 85mm f1.4 DG DN Art at a fraction of the G Master’s cost too. Did Sigma have to cut any corners to achieve the cost savings? Let’s compare these two portrait lenses head to head and find out.
