Flipping the AF/MF switch makes no difference. Switching camera on & off no difference. "Reset Settings" no effect. Problem exists with all DA lenses in my kit. Cleaned mount electrical contacts with isoproply alcohol ("rubbing solution" ?). The SR is stuck off permanently too.
Found others had trouble with the stuck manual focus and I traced threads on this forum and the web. Seems the drive screw in the camera mount does not always engage with the lens. A bit of careful twisting when mounting lens seems to cure it - sometimes.
If it is a software corruption could the firmware be reinstalled? It is v1.3. Can I reinstall this firmware update? Has anyone tried to do a firmware reinstall?
(Hope it is not a hardware issue....
