Good question, focusing was set to AF-S and of course the problem went away when set to manual focus. My other two lenses are the 35/2 and 50/2 and these do not exhibit any kind of chatter at all (they're wonderful by the way). It would do this just sitting on my desk, powered on, pointed toward the room. This will be my second return, the first was due to what I felt were very soft images. Let's hope the third time is the charm.
