Each month, SIGMA introduces new firmware for select lenses, cameras, and mount-converters. In October 2020, SIGMA is rolling out new firmware for Leica L-mount and Canon EF-mount lenses as well as MC-11 EF-E mount converter.

EF-Mount Lenses

Five SIGMA EF-mount lenses receive firmware updates this month:
SIGMA 18-200mm F3.5-6.3 DC MACRO OS HSM | Contemporary lens in EF-mount receives optimized exposure during viewfinder shooting when used in combination with the EOS 90D as well as improved AF accuracy when used with MC-11 EF-E and MC-21 EF-L mount converters.
SIGMA 70-200mm F2.8 DG OS HSM | Sports and 100-400mm F5-6.3 DG OS HSM | Contemporary lenses in EF-mount receive exposure during viewfinder shooting when used in combination with the EOS 90D and the EOS-1D X Mark Ⅲ.
SIGMA 150-600mm F5-6.3 DG OS HSM | Sports lens in EF-mount receives optimized exposure during viewfinder shooting when used in combination with the EOS 90D and the EOS-1D X Mark Ⅲ. A rare communication problem during Live View shooting when shooting with the EOS-1D X Mark III is also fixed.
