Cokin Z-Pro (L) Nuances Extreme ND64 Filter

HArdened Tempered Mineral Glass FilterThe Cokin Nuances Extreme ND64 is a solid neutral density filter that offers a full 6-stop light reduction across the entire filter. Constructed using a new type of tempered mineral optical glass that is 4 times stronger than the previous series, meaning that your filters will withstand those inevitable drops, nicks, and scratches. A new coating process ensure uniform density. This process results in stunning neutrality and absolute colour consistency throughout all types and densities in the series. So switching from one density or style to another will still yield the exact same colour results, no adjustments necessary. These filters have an industry standard 2mm thick glass and rounded corners to make them easy to insert into a filter holder. If a light-tight seal is needed, Cokin recommends using the back slot of the EVO series filter holders.
