NUANCES Extreme filters are made of highly resistant mineral glass, able to resist accidental fall and introduce innovative technology. A new coating process ensures a uniform density and a nano metallic alloy is applied on both sides of a highly resistant tempered glass, resulting in a stunning neutrality. Nuances Extreme Full Graduated ND8 filter allows up to 3 f/stops of light compensation with a very long and uninterrupted transition (“full”) from the top to the bottom of the filter. In this area, the light compensation is only 1 f/stop. This type of full transition refreshes the famous Cokin Creative X121F filter in CR39 resin, now with high-end optical characteristics due to the use of the NUANCES Extreme tempered mineral glass. Round corners and 2.3mm thickness makes Nuances Extreme XL filters easier to insert in extreme conditions. COKIN recommends the use of the Cokin Creative or EVO filter-holders in XL size (X-Pro Series) with the NUANCES Extreme range of filters in XL size.
