NiSi Neutral Density (ND) Filters in optical glass for NiSi V7 (compatible with other brand holders that take 2mm thick filters)

100x100mm ND filters (Neutral Density)

The NiSi 100mm ND filters are available in the following densities: 2, 3, 4, 5, 6, 7, 10, 11, 15 and 20 stops to give you all the tools you need to realise your creative vision. And with the incredible NiSi V7 holder you can mount up to 3 filters in addition to the polariser and shoot without vignetting even at 16mm on Full Frame.

The NiSi IR Series ND filters are made of the highest quality optical glass so as not to lose even the smallest detail in your shot and to make them durable over time.

Thanks to the use of lens grade optical glass and the presence of IR surface treatment on our 100mm ND filters, you can say goodbye to colour shift and time consuming post editing to bring back the true colours.

For long exposures, always remember to close or block off the viewfinder to prevent light pollution creeping into your shot.

NiSi Explorer ND Filters

The NiSi Explorer Collection is made for adventure. The filters feature a special glass hardening process that makes them double the strength of a typical glass filter. The Explorer series are much less prone to accidental breakage and perfect for active photographers. The NiSi Explorer Collection filters are made from B270 tempered glass. It features the same Nano coating process as our optical glass filters.

  • Hardened Glass Filter
  • Less Prone to Accidental Damage
  • Made for Active Photographers that Love Adventure
  • True to life color, No color cast
  • No Vignetting
  • High Definition
  • Nano Coating on Both Sides, Water & Oil Repellent
  • Compatible with the NiSi V7 100mm system
NiSi Explorer Filters

The NiSi Explorer Collection is made from B270 tempered glass, with a lower transmittance compared to our main filters lineup with Lens Grade Optical Glass, but with the peace of mind of having Hardened Tempered glass able to resist accidental damage when falling*.

If you don’t want any compromise in transmittance, discover our NiSi Optical Glass ND and GND range. If price matters most, you’ll find the quality of NiSi Coatings on B270 Glass (same standard as competitors) at a better price in our Explorer range.

*this does not mean it is unbreakable.  After a long period of time, the hardening may decline.

IR treatment

The anti infrared light treatment (or simply “IR“) blocks infrared light beyond a certain wavelength. IR pollution is responsible for the dominant magenta colour cast introduced, or more accurately, allowed through, by low-quality filters. The light absorption curve in NiSi filters is extremely uniform, ensuring a very high colour match.

Why NiSi?

In these graphs, we observe how the response of the NiSi ND (Neutral Density) filter (top left) is uniform, virtually perfect, at all wavelengths; both visible and invisible. It is important to know that even if the eye does not see certain wavelengths, the camera sensor captures them and the colours are altered. All other filters tested (each one of them popular, high priced brands) have a less flat, irregular curve, especially in the final part, infrared.

Essentially, an uneven line in transmission charts demonstrates that the filtration is uneven across the spectrum; the filter is letting in more or less light in certain wavelengths by comparison to others.

Neutral Density filters are so named because they are required to be neutral; to not give bias to any wavelength over another. So if your filter has a tendency to allow excess UV (blue/cooler) or IR (red/warmer) through, you don’t have a Neutral Density filter.
