Nikon HN-12 Polarizing Filter Lens Hood

This screw-in lens hood was originally intended to be used only in combination with the original Nikon 52mm circular polarizing filter. It will not fit new type "II" circular polarizing filters, but it can be used with threaded 60mm polarizing filters in conjunction with the AF-1 52mm gelatin filter holder for 3 x 3" filters. Simply screw on your 60mm polarizer for the AF -1 filter holder and then screw this cap into the front thread of the 60mm polarizer.
