SUMMARY
Sigma has launched its 85mm f/1.2 DG Art lens for L-mount and Sony E-mount, priced significantly lower than Canon and Nikon's f/1.2 options and featuring a more compact, lighter design. Tested on a 61MP Sony a7CR, the lens exhibits excellent sharpness and contrast, particularly from f/2 onwards, with corners reaching perfection by f/2.8. While it offers a substantial light-gathering advantage and shallower depth of field for portraits and low-light events, its primary weakness is persistent longitudinal chromatic aberration at wide apertures. The lens includes a de-clickable aperture ring, silent autofocus, and modest focus breathing, making it suitable for both stills and video.
