Sigma Releases Firmware Updates for 100-400 C, 135 Art Lenses for Canon

From Sigma:
 
For customers who own the SIGMA USB DOCK and applicable product listed below, please update the firmware via SIGMA Optimization Pro.
 


SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary for CANON EF mount
 
Benefit of the update
 
  • It has improved the stability of the image in the viewfinder, making it easier to confirm composition, thanks to the updated control algorithm of the Optical Stabilizer.


SIGMA 135mm F1.8 DG HSM | Art for CANON EF mount
 
Benefit of the update
 
  • When the lens is used in combination with the Canon “EOS R” and their “Mount Adapter EF-EOS R”, or “Control Ring Mount Adapter EF-EOS R”, it has corrected the phenomenon whereby it may occasionally show overexposure when narrowing down the aperture from F3.5 while shooting.


B&H carries the Sigma 100-400mm F5-6.3 DG OS HSM | Contemporary and SIGMA 135mm F1.8 DG HSM lenses.
