From SIGMA:

Thank you for buying and utilizing our merchandise. We wish to announce {that a} new firmware replace for SIGMA’s interchangeable lenses for CANON EF mount listed beneath is now accessible.

This firmware permits compatibility with Canon’s in-camera Lens Aberration Correction operate to allow correction matching the optical traits of every lens. It additionally corrects the phenomenon that irregular photos seem or operation errors happen when the operate is enabled. In addition, it improves performance. Furthermore, there may be an enchancment to the phenomena explicit to some lenses when they’re utilized in mixture with the Canon “EOS R” and their “Mount Adapter EF-EOS R”, or “Control Ring Mount Adapter EF-EOS R”. This was beforehand reported in our announcement of January 16th, 2019.


For prospects who personal the SIGMA USB DOCK and relevant merchandise listed beneath, please replace the firmware through SIGMA Optimization Pro. Before updating the firmware utilizing the SIGMA USB DOCK, please guarantee to replace SIGMA Optimization Pro to Ver. 1.5.0. or later..
