Included:
- NiSi C4 Cinema Filter Holder Kit

--

The NiSi C4 Cinema Filter Holder Kit allows for the convenient use of up to two separately-available 4"-wide, 4mm-thick filters along with an included circular polarizer. This kit comes fully assembled and features an aluminum-alloy filter holder that is pre-installed with two pairs of plastic filter slots, a configuration that accommodates two rectangular filters. Each slot is designed to grip an installed filter only along the surface of the filter's edges. Contact with a filter's front or rear-facing surfaces is avoided, particularly when using graduated filters whose effect can be adjusted to better suit changing lighting conditions or creative demands by sliding them up or down within a filter slot.

Use of the NiSi C4 Cinema Filter Holder Kit can be easily accomplished by first screwing the included 82mm adapter ring onto a lens with 82mm front filter threads. Step-up rings are included to allow the adapter ring to be used with lenses that have 67mm, 72mm, or 77mm front filter threads; while additional step-up rings are separately available for lenses with 49mm, 52mm, 55mm, 58mm, or 62mm front filter threads. After being fitted onto the adapter ring, the filter holder's pull-and-release locking pin helps to provide a reliable connection that allows the holder to be rotated 360°, further benefiting the use of graduated neutral density and other filters that are enhanced by varied positioning.

Together, the 82mm adapter ring and filter holder also accommodate the included NiSi 86mm circular polarizer filter while allowing that filter's edges to be easily gripped for convenient installation or removal. When combined with the filter holder and the adapter ring, as well as an optional step-up ring, the polarizer filter can be rotated to adjust its effect. 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 separately available. The combination of either of those adapter rings with the filter holder cannot accommodate a NiSi 86mm circular polarizer filter; however, a polarization effect can instead be obtained by placing a separately available, 4"-wide, 4mm-thick polarizer filter between one pair of the filter holder's slots.
