I can't seem to get the autofocus on my brand new Nikon 200–500mm ƒ/5.6E lens to work. All the settings (on the lens and camera, including AF switches) are set to autofocus. Trying other lenses on the camera, the autofocus works.
Edit: answering clarification requests from comments:
- By "doesn't work", I mean the autofocus doesn't engage at all—no sounds, no movement.
- The lens is fully seated / locked in the lens mount.
- The camera does not display any error codes. I'm not using a teleconverter or extension tube between the camera and lens.
- The camera body is a Nikon D810.
