Bought this lens used and it was missing the tripod foot. Apparently the camera stores I've called can't order it in so I've been told to go to Nikon. Anyone know where else I can get one? Or will this work: Really Right Stuff - L10: Lens Plate for Nikon 70-200mm/2.8 OR does it hurt to screw my tripod mount right in to the spot where the foot would go? Tried to do some searches on it but no luck. Thanks!
