SmallRig VND Filter Kit 3651, accessories for Star-Trail and Revo-Arcane series matte box, is designed to balance exposure indoors or outdoors or under changing light environment by adjusting luminous flux while the DOF remains the same. It comes standard with two CPLs and one filter tray. Among them, the two CPLs magnetically form a VND filter with 1-8 stop variety, which is manually adjustable and has physical stops. The high-definition CPLs have less color cast, greatly remedying a cross pattern on your image under extreme conditions. This kit features aluminum alloy frame and anti-off safety lock that allows quick release and secure locking of filters as well as prevents fingerprints. It also adopts a variety of quick-release designs to give the greatest quick release convenience to users of Star-Trail and Revo-Arcane series matte box.
