Only with this lens. AF Nikkor 28-200mm F3.5-5.6 G I know according to manual that this has something to do lens that doesn't have a CPU chip built in or the lens is not correctly mounted or the connection between lens and camera are not being properly made. It only happens sportatically. I can turn the camera off and back on and it goes away. My other two Nikon lens do not give me this error. This lens was bought separately from Camera and was the lens I have owned the longest. Any help, tips or opinions. I can see nothing wrong with the contacts.
