Kenko 58mm Filter CLOSE-UP No.3 (Inventory No. 58-6)

This is a meniscus convex lens. When the camera lens is set to infinity (∞), it focuses at a distance of 33 cm from the lens tip. By extending the helicoid, focus can be achieved closer than this. It is not possible to photograph subjects further than 33 cm away.

As this is an old item, there are scratches, dirt, and signs of coating deterioration.
