ARRI 4x5.65" FSND Full Spectrum ND Filter, 2.4

Professional Image Control with ARRI FSND Filters

The ARRI 4x5.65" FSND 2.4 filter represents the pinnacle of external image control. Originally developed as the internal filtration system for the ALEXA Mini and AMIRA, this Full Spectrum Neutral Density filter is now available for front-of-lens applications. It provides 8 stops of light reduction without compromising the integrity of the sensor's color science.

Uncompromising Optical Quality

Designed to meet the rigorous demands of modern cinematography, including Ultra HD and High Dynamic Range (HDR) workflows, this filter ensures true color neutrality. Unlike standard ND filters, the ARRI FSND maintains a perfectly flat spectral response across the visible and infrared spectrum, preventing color shifts and preserving the unsurpassed dynamic range of your camera sensor.

Built for Professional Production

Each filter is engineered for longevity and ease of use on set. The glass features multiple layers of specialized coating for easy cleaning and enhanced durability. For rental houses and owner-operators, the unique laser-engraved barcodes allow for rapid inventory tracking. Every filter comes protected in a high-quality CORDURA pouch lined with MICRODEAR anti-static cleaning cloth.
