Komodo X and Sigma 18-35 autofocus goes crazy!

[Jaime Gómez Lindo]

Hi. I just update to the latest firmware on my KX (2.0.3) and also the firmware of my Metabones Speedbooster. When i turn the switch len for AF, it began to go back and forth from infinity to close and so on non stop. I try to change the autofocus setings on camera but nothing changes. Some of you can have any idea of what is happening? Thanks so much.

Which version of the firmware is the Speedbooster? I've had similar problems with the latest firmware for my speedbooster. After downgrading the autofocus on my Canon worked again.
