NiSi Cinema C4 Filter Holder Kit

The NiSi Cinema C4 Filter Holder Kit is made of CNC machined, aviation-grade aluminum and is ideal for situations where the extra size and hassle of a mattebox is undesirable or unnecessary, but filters are still required.  This kit allows for the convenient use of up to (2) separately-available 4" wide, 4mm thickness filters, along with an included, integrated CPL (Circular Polarizer). The CPL can be rotated independently of the two front filters, which enables control over the amount of polarization desired.

This holder allows cinema grade filters to be used without a mattebox on lenses with a front thread of up to 82mm with included adapters. In such instances, an external dial on the adapter ring allows for the independent rotation of the circular polarizer. Adapter rings for lenses with 86mm or 95mm front filter threads are also available (sold separately). This holder also allows the use of those same filters on stills lenses for both DSLR video and photography.
