Specs
On December 17, Sigma released the latest firmware for its interchangeable lens "SIGMA 35mm F1.2 DG DN | Art" (for Sony E mount). The updated version is Ver.03.
The update includes fix of the phenomenon of rare focusing errors when the focus mode is set to AF-C.
Review
Center sharpness remains high through from f/1.7 to f/11, with f/16 being adversely affected by diffraction. The edges aren't quite as sharp as the centre, with f/2 to f/11 producing the sharpest results.
