Cinema Matte Box Kit

The NiSi Cinema C5 Matte Box Starter Kit combines aluminum, composite plastic and carbon fibre construction for a lightweight, versatile solution. It clamps directly onto 95mm cinema lenses or lenses with filter threads up to 82mm using included adapter rings. The system supports 4x4", 4x5.65" filters and NiSi C5 Rotating Filters with an adjustable top carbon fibre flag.

Filmmakers needing clamp-on versatility

This kit suits cinematographers who require a secure, rail-free matte box for gimbal, aerial or run-and-gun work with mixed lens diameters. The deep filter design prevents vignetting down to 15mm full frame equivalent. It is not suited for productions needing swing-away mechanisms, integrated motorised filter trays or support for front diameters beyond 95mm.

95mm clamp compatibility

The single specification that decides fit is the clamp mounting system designed for 95mm cinema lenses and adapter rings covering filter threads up to 82mm. This allows direct attachment without rods or rails, positioning filters close to the glass for glare control. Buyers must verify their lens front diameter or thread size matches this range before purchase.

Questions about this item

How do I maintain the carbon fibre flag and clamp mechanism over time?

Wipe the carbon fibre flag and aluminum clamp with a soft dry cloth after each shoot; avoid solvents on the composite plastic parts and check the clamp tension before every use to ensure a secure fit on 95mm cinema lenses or threaded lenses up to 82mm.

What causes vignetting first when I push the focal length wider than 15mm on full frame?

The deep filter tray positions 4x4" or 4x5.65" filters close to the front element; going wider than 15mm full-frame equivalent lets the tray edge enter the image circle, so vignetting appears at the filter frame before any optical limit.

Does the matte box trap heat or add noise during all-day gimbal or aerial operation?

The open-frame aluminum, composite plastic and carbon fibre build has no electronics or moving parts, so it generates no noise and adds negligible thermal mass; airflow around the filters remains unrestricted during continuous use.
