Metal Collar Tripod Mount Ring 1/4" for NIKON Nikkor AF-S 80-200mm f/2.8D IF ED
Zero lock up. Wont hold the lens in protrait or landscape no matter how hard ur crank down on the screws
Piece of junk dont waste ur money and buy the real deal. Does not securely fasten to lens. It acts as a collar but lense freely swivels in it reguardless of how hard u tighten the bolt.
