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. Managing light with ND Filters allows you to have a fourth way to control exposure (in addition to ISO, time and aperture).

The ND128 7 Stop NiSi 100×100 filter reduces the light by 128 times without altering the colours, thus allowing shutter speeds to be extended 128 times (for example from 1/100 “to about 1.2”, or from 1/5 “to about 25 seconds).


All NiSi square use Nano Coating®, this wording indicates 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, i.e. the coating that blocks infrared light, and therefore eliminates the risk of magenta colour cast.

Unparalleled Quality

NiSi filters are all made of the highest quality lens grade optical glass so as not to lose even the smallest detail in your images. The special Nano Coating coating on both sides minimizes unwanted reflections and gives the NiSi neutral density filters the characteristic of being water-repellent and oleophobic. There are no comparable quality filters thanks to the exclusive NiSi glass used, with which you can be confidant that your lenses will not lose definition.
