K&F CONCEPT MC UV (Black Frame), Camera Lens Protection Filter Compatible with Fujifilm X100 Series -X100/X100F/X100S/X100T/X100V/X100VI, 28 Multi-Coatings Waterproof HD UV Filter

You’ll need this https://a.co/d/02Y9i8Z2 Before you can even use that filter. But it’s a UV filter, so you can now return that filter. I have the K&F filter adapter and it looks great on the camera. Highly recommend it.
