NiSi Cinema Nano Neutral Density filter ND8 (0.9) 3 Stop – size 4×5.65″

Neutral Density (ND) filters are used to manage the volume of light hitting your sensor.  All NiSi Cinema filters are constructed in NiSi exclusive lens grade optical glass for maximum transmittance, clarity and faithful colour reproduction with no loss of sharpness. Our 4×5.65″ 6K cinema filters are available in 1 to 7 stops.

  • The NiSi 4×5.65 ″ product line is compatible with all leading video matte boxes.
  • The cinema filters from NiSi are the industry standard 4mm thick.
  • A synthetic leather effect storage pouch is included and cinema pouches for your filter collection are available for separate purchase.


NiSi filters are all made of the highest quality lens grade optical glass which has a higher transmittance than standard optical glass such as B270 and much higher than resin. This ensures that no detail is lost in your images. As we are the only manufacturer to use lens grade optical glass for our filters, there are no comparable quality filters on the market.

Unique treatments

All NiSi square filters benefit from the use of the exclusive Nano Coating treatment which makes the filter water-repellent and oleophobic for perfect sharpness. NiSi filters also use IR technology to block infrared light, and therefore eliminate the risk of magenta colour cast. The special Nano Coating coating on both sides minimises unwanted reflections and gives the NiSi neutral density filters water-repellent and oleophobic properties.

Weatherproof and durable

The Nano® Coating treatment gives the filter the quality of repelling water and oils, making cleaning very easy even in extreme conditions or with the presence of seawater. The finishing of the edges and the rounded corners improve grip make our filters easier to handle and rounded corners are far less likely to break off. Our filters and holders are created to be used outdoors, in any weather situation, enjoy photography in its purest essence.
