The filter is the dedicated unit for the lens. It works really well so far although only had one field trip so far. B H Photo are awesome. My second purchase from these guys and my items arrive in the uk with all taxes paid. Cheaper than I can buy locally and a lot quicker than special orders in the UK. Great service all round. Great product.
