Sigma Announces 85mm f/1.2 DG Art for Full-Frame Mirrorless

Sigma has officially confirmed development of an 85mm f/1.2 Art lens built for full-frame mirrorless — a direct challenge to Sony's 85mm G Master and Canon's RF equivalent at likely a significant price advantage. The key claim is sharp-at-f/1.2 performance, which is where most f/1.2 lenses historically fall apart, so that's the spec portrait photographers will want to stress-test when copies hit the market. If Sigma delivers on optical quality and keeps the weight manageable — something they specifically flagged — this becomes the obvious value play for serious portrait and wedding shooters across Sony E, Canon RF, and L-mount systems.
