Can't seem to find any mention of this lens. I like the IR filter in particular which is not just a small square piece of glass but nice big round housed in a plastic casing glued to the lens. I'm thinking to use it to glue to custom lenses for my actioncams. Are they sold separately? Can't find them on Surveilzone.
