NiSi Cinema Nano Neutral Density filter ND4 (0.6) 2 Stop – size 4×4″
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 Nano IRND Cine Filters series uses NiSi advanced Nano Coating technology. This coating, coupled with high-quality optical glass and strict manufacturing standards, give you a filter with accurate colour reproduction, extreme sharpness and low reflection. These features, make the IRND the perfect filter for today high-resolution cameras.
- The NiSi 4×4″ 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.
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. The special Nano Coating coating on both sides minimises unwanted reflections and gives the NiSi neutral density filters water-repellent and oleophobic properties making cleaning very easy even in extreme conditions or with the presence of seawater.
IR blocking treatment
The NiSi Cinema IRND filters also use IR technology to block infrared light and therefore eliminate the risk of magenta colour cast.
Cine Sealing technology
NiSi Cinema ND series use Cine Sealed technology, edges of the filter are sealed with black resin to improve performance and durability. This technology reduces the influence of temperature fluctuations, keeps out condensation and protects the filter from unwanted flare and reflections. Compared to similar treatments, NiSi’s technology allows the edge of the filter to be sealed twice as efficiently, thanks to high-precision machinery and unique materials.
