NiSi Cinema 4x4” Nano IR Neutral Density 1.2 Filter (4 Stop)

Overview

The NiSi Cinema 4x4” Nano IR Neutral Density 1.2 Filter (4 Stop) is a professional square ND filter designed to reduce the amount of light entering the lens by 4 stops without affecting colour balance. It is ideal for shooting in bright conditions while maintaining your preferred aperture, shutter speed, and ISO settings for cinematic exposure control.

Constructed from a single piece of high-quality optical glass, this 10.2 x 10.2 cm filter features NiSi’s Nano IR coating technology to minimise infrared pollution, reduce reflections, and preserve rich blacks with highly accurate colour reproduction. Its dual-sided nano coating also helps protect the surface against water, oil, and scratches, making it well suited to demanding production environments and high-resolution digital cinema capture.
