Cokin offers three series of filter holders – Creative and Evo holders, which are available in a range of sizes, and the newer NX Series. The latter is designed for use with 100mm-type square and rectangular filters from a range of brands including Cokin. What sets the NX Holder apart from most other filter holders is that the filters need to be mounted in an aluminium frame before they can be used. Cokin makes these frames to fit 100x100mm square filters and rectangular graduated filters.
Key features
In an odd quirk, Cokin’s graduated 100mm filters are 143.5 x 100mm, while most of its competitors’ filters are 150 x 100mm. Consequently, Cokin makes two sizesThe holder is made of aluminium and is able to accept a Cokin circular polarising filter (CPL) and up to two square or rectangular filters in their frames. Before it can be mounted on a lens, an adapter ring must be screwed on to the filter thread of the lens. The low profile of the holder and the filter frames mean that the system is suitable for use with focal lengths as short as 16mm.
