Firmware update for SIGMA’s interchangeable lenses for CANON EF mount

Thank you for purchasing and using our products.

We would like to announce that a new firmware update for SIGMA’s interchangeable lenses for CANON EF mount listed below is now available.

This firmware allows compatibility with Canon’s in-camera Lens Aberration Correction function to enable correction matching the optical characteristics of each lens. It also corrects the phenomenon that abnormal images appear or operation errors occur when the function is enabled. In addition, it improves the functionality. Furthermore, phenomena particular to some lenses when they are used in combination with the Canon “EOS R” and their “Mount Adapter EF-EOS R” or “Control Ring Mount Adapter EF-EOS R” that we announced on January 16th, 2019 are also improved on by this firmware.

For customers who own the SIGMA USB DOCK and applicable products listed below, please update the firmware via SIGMA Optimization Pro※.
