This is a Black Mist 49mm filter No. 5. I used it for portraits and other types of photography, but I'm selling it now because I haven't been using it recently. It has scratches and dirt because I carried it around in a case and attached to a lens. Please check the photos. There are no problems with its practical use. This is a used item stored at home. Please understand this before making a purchase. It will be shipped in simple packaging.
