Focus shift has nothing to do with the camera firmware. It is a characteristic of the optical design.
That being said, the focus shift characteristic could be stored into the lens' firmware. The camera could then compensate the shift during AF based on this data. However, the correct approach would be to AF with the lens stopped down which is, of course, possible on mirrorless cameras (except in very low light).
Thus firmware v1.1 may have such a compensation algorithm in place (Pentax does it as well I think).
However, this wouldn't help in manual focus mode.
As of today I can't promise a test in the immediate future.
