NiSi Cinema C4 Filter Holder Kit

The NiSi C4 Cinema Filter Holder Kit delivers cinema-grade filtration without the bulk of a traditional matte box. This lightweight, CNC-machined system holds up to two 4-inch filters plus an integrated CPL, enabling professional light control on lenses from 62mm to 82mm (adapter rings available for larger threads).

• CNC Machined Aluminum Construction: Aviation-grade aluminum provides durability and minimal weight for handheld camera rigs.
• Dual 4-Inch Filter Capacity: Accommodates two separately-available 4"-wide, 4mm-thick cinema filters for flexible effect stacking.
• Integrated CPL: Built-in rotatable circular polarizer allows glare reduction and sky saturation without using a filter slot.
• Independent Polarizer Rotation: CPL rotates independently from front filters for precise polarization control.
• Compact Alternative to Matte Box: Eliminates bulk while maintaining cinema-grade filter performance for lightweight productions and handheld work.
• Included Adapter Rings: Standard 62mm, 72mm, and 82mm adapters included; 86mm and 95mm adapters available separately.
• Hybrid Workflow Support: Use cinema filters on both dedicated cinema lenses and standard DSLR video/photography lenses.
