Summary:
The dual HLA motors and two separate focus groups result in faster autofocus than both the Canon RF 85mm f/1.2 and Nikon Z 85mm f/1.2.
It is sharper than the Sigma 85mm f/1.4 DG DN Art across the frame, including at f/1.2.
Compared with the Sony 85mm f/1.4 GM II, the Sigma is sharper in the center of the frame. However, at f/1.4, the GM II is sharper in the mid-frame and corners than the Sigma at f/1.2.
At f/2, the mid-frame performance is roughly equal, but in the corners, the GM II has higher contrast but less microdetail.
At f/2.8, the Sigma 85mm f/1.2 is sharper in the center, mid-frame, and corners.
It sounds like it might arguably be the best 85 f/1.2 regardless of brand. Sigma has been doing a nice job on lenses these days. If you can live with the artificially imposed Sony limitationis (on an 85 f/1.2, I think most can), it is hard to argue with this or many other of their lenses coming to the top of the list.
I think as usual, Dustin's hip-fire sound byte analysis missed the mark in regards to the Z version's AF. Just because it has the dual STM doesn't mean it doesn't have extremely responsive AF. I have Viltrox lenses with "linear" motors that have worse AF than Nikon S lenses with "just" STM.
