NiSi 100x100mm ND filters

NiSi 100x100mm neutral density filters are the ideal tool for your long exposures.

Optical glass, not resin: surface coatings absorb the light, with no colour casts and minimal impact on sharpness. 100mm wide and 2mm thick, for the NiSi V7 Holder, which takes up to 3 filters plus the polariser with no vignetting even at 16mm on full frame, and for other brands’ holders of the same size.

How many stops do you need?
