Firecrest ND 4x5.65 ND Neutral density Filter 0.6 (2 Stops) compatible with all 4"x5.65" matte boxes

Firecrest Neutral Density is a revolutionary new type of ND filter from Formatt-Hitech. Rather than dyed resin, Firecrest is a carbon metallic coating used to create hyper neutral NDs. The filters are made from 2mm thick Schott Superwite glass, and the multicoating is bonded in the middle to increase scratch resistance. Firecrest Filters are neutral across all spectrums, including UV, visible, and infrared.
