Add CPL and VND functions to your matte box with this Multifunctional VND Filter Tray Kit from SmallRig. The kit includes a filter tray that fits SmallRig matte box models 3556, 3645, 3641, and 3646, as well as two magnetic circular polarizer filters that can be used together to create a VND effect using the integrated rotating gears.

The CPL filters quickly stack into the matte box using magnets, and they can be adjusted for 2 to 5 stops of light reduction into the lens. There is no vignetting for lenses with a focal length of ≥16mm. The filters are made from optical glass that features multicoating for accurate color rendition within 350 to 700nm wavelengths.
