A new Sigma firmware update is out for a few of Sigma’s Canon EF mount lenses, as well as a single Nikon F mount lens and the Sigma MC-11 EF-E converter.

This update specifically focuses on compatibility with Canon’s in-camera Lens Aberration Correction feature. Sigma wants to make sure the corrections match the look of each lens and that there are no errors when the feature is used.

Compatibility between Sigma EF lenses and Canon’s EF to RF adaptors for the EOS R will also be improved with this update.
