NiSi Cinema 4x4" Nano IR Neutral Density 2.1 Filter (7 Stop)

Overview

The NiSi Cinema 4x4" Nano IR Neutral Density 2.1 Filter (7 Stop) is a professional square ND filter designed to reduce the amount of light entering the lens by 7 stops without affecting overall colour balance. It is ideal for filming in very bright conditions while maintaining your chosen aperture, shutter speed, and ISO settings for greater creative exposure control.

Made 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 contamination, suppress reflections, and preserve deep, neutral blacks with excellent colour accuracy. Its dual-sided nano coating also helps protect the surface from water, oil, and scratches, making it a reliable choice for demanding cinema and video production environments.
