Olympus 49mm Filter CLOSE-UP f=40cm (Inventory No. O49-2)

This is a meniscus convex lens. When the camera lens is set to infinity (∞), the focal point is 40 cm from the tip of the lens. By extending the helicoid, you can focus on subjects closer than this. It is not possible to photograph subjects further than 40 cm away.

There are noticeable scratches and deterioration of the coating.
The box is torn.
The plastic case has cracks and scuff marks.
While I believe there are no major functional issues, this is my personal opinion. Please refrain from purchasing if you are concerned about minor details.
