I did a test of the product, for the price it goes but it's still a mark "low coast" brittle plastic, and if I knew how water effects as I wished, he had post-treatment anyway because there is a kind veil fog on photos and especially namely impossible for a super wide angle !!!!! 12 mm on my Nikon DX 12-24 mm that makes circles on the sides as too small filters.
