ND filter 150x150mm ND256 (2.4) 8 Stop

NiSi neutral density (ND) filters are the ideal tool for managing light in the field. Thanks to the wide range of densities available, NiSi ND filters allow you to extend shutter speeds even in bright conditions. The ND256 8 Stop NiSi 150x150mm filter reduces the light by 256 times without altering the colours, therefore it allows you to lengthen the shutter speed 256 times (for example from 1/30 “to about 8”, or from 1 “to about 256” that is 4 minutes and 26 “).

NiSi filter ND256 (2.4) Nano IR 8 Stop 150x150mm

Nano® indicates the use of the Nano Coating treatment, IR is the coating that blocks infrared light, and therefore the dominant magenta colour. While ND256, (2.4) and 8 stops are different ways to indicate the value of light absorption of the filter in question. The filter measures 150x150mm with a thickness of 2mm.

Unparalleled Quality

NiSi filters are all made of the highest quality lens grade optical glass so as not to miss even the smallest detail in your images. The special Nano Coating coating on both sides minimises unwanted reflections and gives the NiSi Neutral Density filters the characteristic of being water-repellent.

Unique in the market

Thanks to the very high chromatic correspondence and absence of dominant colours, you can finally say goodbye to improbable colour corrections in post production.
NiSi optical glass is not the classic B 270 used my many manufacturers, but a superior quality lens grade glass used by major photographic manufacturers specifically for the finest optical elements. NiSi filters do not degrade the image and your lens and photographic sensor will always work to their full potential. In addition to the IR block, NiSi filters also block ultraviolet (UV) light, for an even more precise colour match.


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 sea spray. The finishing of the edges and the rounded corners improve the resistance of the filter and the grip.
