Thank you for viewing. This is a snap-on, metal lens hood for Nikon manual standard lenses: * Ai 50mm F1.8 * Ai-S 50mm F1.8 It can also be attached to other standard lenses with a 52mm filter thread. Later versions have the product name printed on them, but this product is the older "engraved" type. There is no significant damage, but there are many small scratches and dirt marks. Please refrain from purchasing if you are sensitive to these details, as this is an old item. The price reflects a discount, so price negotiations are not possible. Thank you for your understanding.
