The NiSi 138mm Mounted Linear Polarizer Filter is a high-performance linear polarizer designed to fit seamlessly into the 138mm donut of a matte box system. Ideal for both still and motion picture applications, this filter enhances your visuals by reducing reflections from non-metallic surfaces like water, glass, and polished stone, while boosting color saturation and contrast for richer, more vibrant imagery.

The filter can be rotated within the mount to precisely control the degree of polarization, allowing filmmakers and photographers to fine-tune their shots in varying lighting conditions. It also helps manage reflections and glare from LCD screens or other digital displays, making it a versatile tool on set.

Riley ★★★★★

I was worried about fitting this into my matte box, but the 138mm donut mount was perfectly snug. It cuts reflections beautifully without shifting color, and the ring rotates smoothly even with gloves on.

Steven V. ★★★★★

Cutting glare on a sunny lake shoot was effortless—the polarizer cleaned up reflections without any color shift. Solid build, and the rotation ring moves smooth enough for fine adjustments on the fly.

Ellie ★★★★★

Finally got this mounted on my matte box and the difference in cutting reflections is night and day. The 138mm ring clicks into place perfectly and feels solid. Very happy with how it handles glare on a bright outdoor shoot.
