Sigma 85mm f/1.4 FE preorder at BHphoto, Adorama, FocusCamera.
The German Youtube channel Krolop&Gerst made a 45min long comparison between the best 85mm FE lenses. The Sigma holds up very well against the Sony GM:
- Sigma is sharper in the center
- Sony GM has better sharpness in the corner
- Sigma has a lot less CA
- Similar Bokeh performance
- very similar AF performance although the Sony seems to have a slight advantage on eye-af
Just switch on the auto translated subtitles if you don’t understand German:
