NiSi ND64 (6 Stop) + CPL PRO Nano HUC IR SLIM

The NiSi ND64 filter + CPL circular screw polariser is the ideal tool for amateur and professional photographers to approach the world of long exposures using a combined 6 stop ND and polariser. This product, the brainchild of the NiSi development team gives you the convenience of an ND along with a fully functioning, rotating polariser.

No more additional glass that reduces the quality, no more stacking filters one above the other, no more increase in vignetting. The ND64 NiSi PRO Nano IR + CPL Filters are the only ones in the world offered exclusively in lens grade optical glass for precision applications of the highest quality and different coatings (Multi Coating) such as: Nano Coating, IR, Anti-glare, water repellent and resistant coating with grease and oil and an integrated high-quality CPL polarising filter. Circular screw NiSi ND64 + CPL filters are available in several popular sizes, from 62mm to 82mm and 6 stops ND64.

Made with high quality, neutral, lens grade optical glass, the NiSi ND64 + CPL circular screw filter is perfect for creative effects such as:

  • Decrease the depth of field with strong brightness
  • Control timings in videos and time-lapse
  • Make the water look like silk
  • Give movement effects to clouds
  • Simultaneously with the above effects, reflections can also be controlled thanks to the integrated polariser

If you want to add a glass in front of your lens, make it of the highest optical and constructive quality.


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 the dominant magenta colour.

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 minimises 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.

Unique on the market

Thanks to the very high chromatic correspondence and absence of dominants, you can finally say goodbye to impractical and time consuming colour corrections in post production. NiSi optical glass is not the classic B270 used by many manufacturers, but it is a superior quality glass used by the major manufacturers of photographic lenses specifically for the finest optical elements, NiSi filters do not degrade the image and your lens and photographic sensor will always work at maximum of their potential.


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 water. The finishing of the edges and the rounded corners improve the resistance of the filter and the grip. Our filters and holders are born to be used outdoors, in any weather situation, enjoy photography in its purest essence.

CPL included

The front element of the ND64 + CPL filter rotates, and thanks to the presence of a polarising film, allows you to obtain the effect of the polariser together with that of a classic 6 Stop ND filter. In this way it is easier and more practical to use ND + Polariser, without having to screw two filters one on top of the other which could cause vignetting on some wide-angle lenses.

Polariser effect + ND64

    I already have the 82mm version for my 135mm 1.8 that I use for panning through the fence at motorsport events (allowing me to have a slow shutter speed but the aperture wide open, losing as much of the fence in the image as possible) so it was a no brainer to get this 77mm version for my newly acquired 70-200mm 2.8. Looking forward to using this when the motorsport season starts next month.
