Sigma updates firmware for many Canon EF lenses

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, there is an improvement to the 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”. This was previously reported in our announcement of January 16th, 2019.

For customers who own the SIGMA USB DOCK and applicable products listed below, please update the firmware via SIGMA Optimization Pro. Before updating the firmware using the SIGMA USB DOCK, please ensure to update SIGMA Optimization Pro to Ver. 1.5.0. or later..

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 restarting the camera does not work when the lens is taken off the camera while the lens’s OS function is in operation.

SIGMA 120-300mm F2.8 DG OS HSM | Sports for CANON EF Mount Update

It has ensured compatibility with Canon’s in-camera Lens Aberration Correction function, which enables correction matching the optical characteristics of the attached lens. *
It has corrected the phenomenon that abnormal images appear or operation errors occur when Canon’s in-camera Lens Aberration Correction function is enabled.
It has improved the AF accuracy when the lens is used with the SIGMA MOUNT CONVERTER MC-11 EF-E.

SIGMA 150-600mm F5-6.3 DG OS HSM | Contemporary for CANON EF Mount 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.
