I have not tried this but have been sent some information from one of my Sony contacts (this is not endorsed by Sony). It appears to be a very similar adapter to the metabones adapter but with the addition of the ability to use the one push auto focus button on the camera to set the focus. You don’t get continuous auto focus and I have no idea if the adapter is any good, but at only $250 it’s got to be worth a try. You can find them on ebay but I have no other information at this time other than the video below.
