Thank you very much for viewing. This is an Inon UCL-165AD close-up lens for both land and water use, and a conversion spacer. I purchased it used with the intention of using it, but I haven't had the opportunity, so I'm not familiar with the detailed specifications. There are scratches on the resin parts, but there are no visible scratches on the lens. Please judge the condition based on the photos. Everything in the photos is included. I have a pet (dog), so please be aware if you are sensitive or have allergies.
