Kenko PL Finder "R" This is a small-diameter PL filter that attaches to the "hot shoe" of film cameras, mirrorless cameras, etc. Size: W34 x H39.8 x D15mm Weight: 16g I received this from an acquaintance, and I searched for it, but the mirror base is cracked. Also, the attached rod seems to have been modified for better usability. I don't think there are any noticeable stains on the lens. This product is no longer in production, making it difficult to obtain. It's a bit of a "problem child," but please check the photos and consider purchasing with your understanding.
