The V5 Pro 100mm Filter Holder from NiSi is the most advanced 100mm filter holder on the market today. The NiSi V5 Pro Filter Holder allows you to use three 100mm filters in any combination as well as a circular polarizing filter. With the unique rotation wheel design, the circular polarizer can be rotated via a cog on the back of the holder. This means you no longer have to set the CPL filter before inserting other filters. It is made from a single block of aviation-grade aluminum and has a matte black frosted finish to minimize reflection. This V5 Kit comes complete with an ultra slim 86mm landscape polarizer, 4 adapter rings for most popular wide angle lenses (67mm, 72mm, 77mm, and 82mm), and a leather carrying case.
