This is a close-up lens that can be used with the same feel as a Kenko filter. You can easily take close-up shots just by attaching it to your lens. It's available in 52mm and 49mm diameters. I used it with a film camera SLR, but I haven't used it for a long time and it has been in storage. It looks clean and doesn't have any major scratches, but since it's a used item, there may be fine scratches if you look closely. Please be aware that those seeking high-quality items or items in like-new condition may not be satisfied. Please consider purchasing only if you understand the above.
