With technology taken from the ALEXA Mini and the AMIRA internal filters, ARRI Full Spectrum ND 2.4 Filter 8-Stop 4x5.65"introduces a line of external front full spectrum neutral density filters. The 4 x 5.65" ARRI Full Spectrum ND 2.4 Filter 8-Stop 4x5.65"absorbs 8 stops of light to reduce very bright illumination conditions, allow use of wide apertures, or add blur and motion effects to a subject during long exposures.

ARRI uses SCHOTT B270i glass for absolute flatness and pure neutral color rendition and hydrophobic and oleophobic coating for easy and fast cleaning. ARRI-coated filters provide lower reflectivity in the visible spectral range between 400 and 750nm and higher reflectivity in the near-infrared spectral range to produce a high dynamic range, improving color, neutrality, and contrast. Each filter has a unique engraved barcode for inventory and ID purposes and comes with a protective Cordura pouch lined with MICRODEAR antistatic cleaning cloth.
