Sigma has announced firmware updates for two of its most recent lenses, the 35mm F1.4 DG HSM A012 (Canon mount) and 17-70mm F2.8-4 DC Macro OS HSM C013 (Canon, Nikon and Sigma mounts). The lenses must be updated using Sigma's USB Dock, and owners should download the latest Version 1.1 of Sigma Optimization Pro software first, which allows any user-defined AF microadjust settings to be retained after updating the lens.

According to Sigma, the updates offer the following improvements:

17-70mm F2.8-4 DC MACRO OS HSM C013 - Version 1.01 for Canon, Nikon and Sigma improves the stability of the Optical Stabilizer's operation, and (for Canon mount only) refines the AF algorithm to reduce the operating noise.

35mm F1.4 DG HSM A012  - Version 1.02 for Canon refines the AF algorithm to reduce the operating noise, and improves the smoothness of AF as it starts up and stops.

Press release: 

The latest version of SIGMA Optimization Pro, Ver1.1 is available for download.
