ARRI released a new line of full-spectrum neutral-density (FSND) filters that it said replicate the filtering built into the Alexa Mini and Amira in an external form factor. FSND filters allow DPs to shoot at wider T-stops without overexposing the image by reducing the amount of light entering the lens, and are especially useful when shooting with cameras that have highly sensitive digital sensors.

Sets of ARRI FSND filters come in eight different densities from 0.3 to 2.4 at each of two sizes: 6.6″ x 6.6″ and 4″ x 5.65″. They are made from Schott B270i glass polished flat, with completely parallel surfaces to maintain sharpness even when shooting wide-open at long focal lengths, ARRI said. The filters are designed with curved edges to reduce chipping and are colored black to reduce light scattering, ARRI said.
Each ARRI filter comes with a Cordura and Microdear anti-static pouch designed to clean the filter every time it slides into or out of the pouch. An engraved GS1 bar code near the filter’s edge is designed to uniquely identify each filter without requiring stickers, which is useful for monitoring a reseller’s inventory, establishing ownership, or attempting to recover them after theft.
