For the Touit e-mount lenses the FW upgrade was possible.I haven't seen the answer mentioned anywhere myself, and it is not inspiring since full AF support on current A7 series bodies and easy update in future is the only reason I would consider Batis 85/1.8 among a myriad of other wonderful options in that focal length.
