Made of optical glass, these filters have anti-reflective multicoating to reduce lens glare and optimize light transmission. They also feature a protective nano-coating that is waterproof, making them ideal for use in any type of photography and in harsh environments. The ND4 filter can be used by itself with the Swift Friction Mount System adapter ring or added on to the NiSi True Color VND 1-5-stop variable ND filters for even more protection against light.
