NIKON 50/2 Metal Lens Hood, F Large Letter Black Paint Fits 52mm diameter lenses A cool metal hood from the Nikon F era. There are a few scratches. No dents. Being black painted metal, the scratches add to the cool factor, which is a good thing about hoods from this era. Please attach it to an old Nikon lens. It also protects the lens. In fact, I myself have avoided lens damage several times thanks to metal hoods. If it bends, straighten it with pliers. That's the kind of hood it is. No returns or exchanges, please.
