Kenko OPTICAL FILTER for COLOR Kenko Filter 52.0s P.X #1 This item belonged to my father, but he no longer uses it, so I am selling it. I took it out of the box and opened the case for the photos. He said it's either unused or hardly used, but it's probably been around for a while. I don't see any noticeable scratches, but I hope you understand. Thank you for your purchase.
