My Oly 7-14 Pro lens is stuck in manual focus. No, I did not forget to engage the clutch ring. This lens malfunctions on 2 Oly cameras. Meanwhile my Oly 12-100 is working perfectly on both cameras, so settings are ok. Contacts cleaned. Any ideas?
So when you slide the clutch back to the AF position, the camera screen still shows MF, correct?
Try going into the cameras menus and disable the manual clutch ring. There is an option to ignore it so it doesn't do anything anymore. If after changing to that the camera now normally AF's that lens, then it sounds like the switch on the clutch ring is broken and not switching back to the AF side.
