This 77mm Black Mist 1/4 Filter from NiSi is a diffusion filter designed to fit the Swift System True Color VND (Variable Neutral Density) filter. This filter cuts UV (Ultraviolet) light transmission below 390nm and IR (Infrared) light transmission above 700mn, while retaining the regular visible light spectrum. This makes it ideal for use with cameras that do not have an IR filter installed in front of the sensor, like the Black Magic Pocket and Red video cameras.

Made of optical glass, this filter has anti-reflective multicoating to reduce lens glare and optimize light transmission. It can be used with the Swift Friction Mount System adapter ring or added on to the NiSi True Color VND 1-5 Stop / 5-9 stop variable ND filters for even more protection against light.
