This is a nice 72mm circular polarizer filter made by Nikon with cool vintage styling. Use it to cut down on unwanted reflections in your shots.
Included is the matched HN-13 lens shade for the 72mm polar filter on the 180mm f2.8, 300mm f4.5, and 400mm f5.6 lenses.
It is in excellent condition with light wear and works perfectly. The glass is clean and scratch-free with no haze, fungus or other problems. The mechanical functions are smooth. The shade is also in great shape with no dents or major wear.
