Here is some good news for owners of Canon / Sony cameras and Sigma lenses for the EF mount: today Sigma has released new firmware versions for several lenses and the MC-11 adapter which patch different bugs and improve compatibility. Some of the lenses are now compatible with Canon’s in-camera Lens Aberration Correction function, while others should no longer have bugs which either reduce shooting speed continuous in combination with some cameras or make the autofocus speed “unstable” (whatever that means).
Down below is a list with all the changes. You can download the new firmware versions over at sigma-global.com.
