Formatt Hitech 6x6 inch Pro Stop 8 2.4 Neutral Density Filter

165mm is a high-end system for photographers using large-barrel, wide-angle lenses such as the Nikon 14-24. Fits the Formatt-Hitech 165mm Formatt-Hitech or Lucroit holder system, so a single filter is usable on multiple lenses. Made from the highest quality optical resin available, with an index of refraction nearly identical to the finest optical glass. High scratch resistance, low material fatigue, and chamfered corners to resist breakage so the filter will provide years of service. Made in the UK using the world’s most advanced, computer-controlled filter manufacturing technologies.
