>>3060672Sony is working on adding Tracking capability to the LAEA3 adapter so the A-mount lenses works with new AF.
Once the A-mount adapter is updated, it will probably be reverse engineered into Metabones and Sigma adapter.
The Caveat is the speed will drop down to 10 FPS, because the A-mount motor weren't made for this new AF routine. And the unfortunate part is it will affect your Canon lens too, since the camera will simply assume your Canon lens is A-mount.
