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 Z121F filter in CR39 resin, now with high-end optical characteristics due to the use of the NUANCES Extreme tempered mineral glass. Round corners and 2mm thickness makes Nuances Extreme filters easier to insert in extreme conditions. COKIN recommends the use of the NX-Series 100 filter-holder to ensure efficient light-leaks protection and the reduction of vignetting issues with the NUANCES Extreme range of filters in L size (a filter frame of the NX-Series range is necessary). Nuances Extreme filters in L size are also compatible with existing Cokin Creative or EVO filter-holders in L size (Z-Pro Series).
