99.9% polarization rating

Nitto polarizer film on optical glass

Resin-sealed edges

Precision ground and polished

Fits NiSi C4 Cinema Holder

The NiSi Cinema 4x4" Linear Polarizer Filter combines high-quality optical glass with Nitto polarizer film for a 99.9% polarization rating. Its resin-sealed edges and precision grinding are designed for durability and maximum sharpness.


  • 99.9% polarization rating: Nitto polarizer film combined with NiSi's optical glass reduces reflections on non-metallic surfaces and enhances color saturation.
  • Resin-sealed edges: Keeps moisture from entering the filter for improved durability.
  • Precision ground and polished: Applied after the film is added to ensure maximum sharpness.
  • Fits the NiSi C4 Cinema Holder: Pairs with the C4 system for a lightweight, quick-to-mount setup on lenses with standard filter threads.
  • Autofocus/metering note: Recommended for use when not relying on in-camera autofocus or exposure metering, since linear polarization can affect both.
