"The Digital Camera Telephoto Lens is an attachable/detachable lens suitable for most digital cameras, digital video cameras, camera phones and web cams. If you can take pictures or film with it, you can stick this on it. There's no complicated attachment process; an easy to apply magnetic ring is all you need. Simply remove the protective film from the ring, affix it to your camera or phone, and magnetically attach the lens."
