Recently, the autofocus on my nikon D3100 cannot work. The ring of the lens wouldn't even turn when i tried to focus. However, when switched to manual mode, the camera works fine.

When I used a different lens on the camera, the autofocus still does not work.

Is this fixable? Or do I have to change camera?
