AF-S VR 200-400mm - Protective glassSome users have experienced confusion concerning the "lens protective glass" supplied with the AF-S VR 200-400mm lens. The manual describes how to attach this lens protector. However when the supplied filter case is opened, users discovered it to be empty. Please note that the lens protective glass is supplied attached to the lens and this is performed at the Nikon factory. The protective glass should be left in place at all times and should only be removed if photographing subjects that contain a bright light source. Under these circumstances, removing the protective glass may prevent ghosting from occurring.The two photos below show the filter attached to the lens (top) and removed (bottom): Print Share By Email Share By Social Ask A Question FaceBook Twitter
