Add variable neutral density filtering to your lens with this Variable ND Filter Kit from SmallRig. The kit includes three circular polarizer filters that each cut different levels of light from your lens. The magnetic filters can be stacked and adjusted in a separately available clamp for select matte boxes, and in this configuration two circular polarizer filters can be used together to create a variable ND effect.
When putting CPL 1 and CPL 2 filters together, they can adjust for 2 to 5 stops of light reduction into the lens. When putting CPL 1 and CPL 3 filters together, they can adjust for 6 to 9 stops of light reduction into the lens. There is no vingnetting 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.
Quick Features
- Dual CPL+VND filter function with quick release magnetic attachment for safety and reliability
- When using CPL1 with CPL2, it achieves a VND effect of 2 to 5 stops; when using CPL1 with CPL3, it achieves a VND effect of 6 to 9 stops
- Hard stop and light transmission limit technologies eliminate the VND X-pattern effect
- Delivers high-definition throughout the entire focal range, with accurate color reproduction in the 350-700nm wavelength range and minimal color distortion
- Offers vignette-free performance across focal lengths ≥16mm
