The NiSi Cinema 4 x 5.65” (12mm) Variable Neutral Density 0.6-1.8 (2-6 Stops) Filter is a variable natural density filter with the range of 0.6-1.8 or 2-6 stops. It creates a darkening of the entire image, allowing a cinematographer to shoot with a wider aperture or slower shutter speed. The degree of density is easily controlled by rotating the gear or combining a large lens motor to control the density. The aluminum and glass filter is 12mm thick and occupies two filter slots in a compatible 4 x 5.65″ matte box or can be used without a matte box. It offers 2 to 6 stops of neutral-color light reduction and features NiSi’s optical glass. The gear features stop marks to identify the density.
The NiSi Cinema 4 x 5.65” (12mm) Variable Neutral Density 0.6-1.8 (2-6 Stops) Filter includes a 15mm support rod to mount the lens motor and soft case.
Please note the matte box and lens motor in the images are to demonstrate the use and are not included.
