My daughter just purchased a Nikon d3200. She is using my old lens (Nikkor af 50mm 1:1.8d). She had been shooting in manual focus since she got the camera. Now we are trying to figure out how to change to auto. When I click on the i on the back I am unable to access the focus modes it just shows m. Looking at the menus I cannot see any way to change this setting. The lens doesn't have a button to change from auto to manual so this isn't the issue. Why is this happening? What am I missing to change this very basic setting? This is driving me insane. Please, somebody help!
