That would depend on what lens adapter you are using. The WCON-08E has a 55mm thread and should have come with an adapter to bring it down to 43mm. My adapter uses 62mm threads on the lens end so I would need a step down ring or a conversion ring to go from 62mm to 55mm. If you know what adapter you have we can help you as not all adapters use 62mm. If you don't have a lens adapter you will need to get one before you can do much.
