NiSi 100mm Filter System
The 100mm Aluminum Filter Holder Foundation Kit from NiSi is the most advanced 100mm filter holder with superb built quality. The Nisi Filter Holder allows you to use 3x 100mm filters and a circular polarizing filter in any combination. It is made from aviation-grade aluminum with single element processing by CNC machine. This foundation kit comes complete with an ultra slim 82mm CPL filter and 4 adapter ring for most popular wide angle lenses (67mm, 72mm, 77mm and 82mm). The matte black frosted finish on the surface minimizes reflection. With the unique rotation wheel design, the CPL filter can be rotated via a cog on the back of the filter which means you no longer have to set the CPL filter before inserting the other filters.
