This is the drop-in circular polarizing filter for use with the Nikon 200mm f2G AF-S VR and Nikon 800mm f/5.6E FL ED AF-S VR only. Its small rotating dial on the outside of the filter holder is used to adjust polarization.
This filter does not fit or work with any other Nikon lens. If you need a drop-in filter for any other Nikon Super Telephoto lens, look here.
