This product is in working condition. It is an old lens, so it is for manual focus (MF) use. To prevent any issues, please confirm the following before purchasing. I have taken photos and confirmed that it works. This is a rare lens that can change the color tone with the built-in filter. I purchased it for around 70,000 yen originally. ● Brand/Manufacturer: Nikon ● Model Number: FISHEYE-NIKKOR 16mm 1:3.5 There are some minor scratches, but I think it's in good condition considering its age.
