NUANCES Extreme filters are made of a highly resistant mineral glass, able to resist accidental fall and introducing innovative technology. A new coating process ensures an uniform density and a nano metallic alloy is applied on both side of a highly resistant tempered glass, resulting in a stunning neutrality. Nuances Extreme ND8 catches 3 f/stops of light, dedicating its use to long-exposure photography and/or depth of field reduction in extremely bright conditions for video shooting. Round corners and 2mm thickness makes Nuances Extreme filters easier to insert in extreme conditions. COKIN recommends the use of EVO filter-Holder to ensure an efficient light-leaks protection.
