Like clockwork, SIGMA has released its December 2020 updates for select lenses. This time, five lenses in Canon EF-mount, one in Sony E-mount, and one in SIGMA SA-mount are the beneficiaries. With the exception of the 120-300mm F2.8 DG OS HSM | Sports in SA-mount, every lens that receives a new firmware this time is a prime lens.
SIGMA continues to improve the compatibility of its EF-mount lineup with the newly released Canon EOS 90D and EOS-1D X Mark III. The fine Art-series lenses that receive new firmware this time include four full-frame lenses and one APS-C lens:
- SIGMA 28mm F1.4 DG HSM | Art
- SIGMA 70mm F2.8 DG MACRO | Art
- SIGMA 85mm F1.4 DG HSM | Art
- SIGMA 135mm F1.8 DG HSM | Art
- SIGMA 30mm F1.4 DC HSM | Art
This update will optimize the exposure during viewfinder shooting when mounted on the couple of new Canon cameras released in 2020.
The SIGMA 120-300mm F2.8 DG OS HSM | Sports lens will have improved optical stabilization in Mode2 when used with SIGMA MC-21 SA-L mount converter.
For Sony E-Mount, SIGMA continues to improve the 35mm F1.2 DG DN | Art released this year. This time, the update will resolve the rare autofocus failure issue in AF-C mode.
Additionally, the MC-11 SA-E and MC-11 EF-E mount converters will receive support for the aforementioned EF-mount and SA-mount lenses that have been updated with the latest firmware.
