No vignetting, with Nano coating and water repellent for easy cleaning
It allows you to adjust the intensity of light absorption from ND 5 up to 9 stops
Ultra-high-quality HUC (High-ultra Clarity) optical glass - a NiSi-exclusive detail-free glass
Perfect together with the ND-VARIO Variable 1.5-5 stop Nano-coating Filter

The NiSi ND-VARIO Variable 5-9 stop filters are the ideal tool for photographers who want to approach the world of long exposures and for videographers who want to be able to control the light, even in real time during shooting, without introducing heavy artifacts or aberrations. NiSi has created a unique filter of its kind, thanks to the NiSi ND-VARIO you can use a single filter to obtain a reduction of the light entering the lens from 5 to 9 stops. The characteristics and qualities of the filter make it possible to avoid any "X-cross effect" that other variable ND filters suffer from. Aberrations are minimized *.

The unique optical glass that made the NiSi brand famous was also used for this Variable ND, because quality does not compromise. There is also the Nano Coating treatment that makes the surface waterproof and resistant to grease and dirt. Cleaning the filters has never been easier. NiSi ND Variable Nano Screw Filters are available in many sizes from 40.5mm to 95mm.

The front thread is one step higher than the rear one (except the 95mm version), for example:

67mm rear thread -> 72mm front
72mm rear thread -> 77mm front
77mm rear thread -> 82mm front
82mm rear thread -> 86mm front
95mm rear thread -> 95mm front
Made with the highest quality neutral optical glass, the Screw-in Circular Variable ND NiSi Filter is perfect for achieving creative effects such as:

Decrease the depth of field with strong brightness
Check the times in the videos and time-lapse
Make water appear like silk
Thanks to the ability to adjust the absorption from 5 to 9 stops, the filter is very versatile, and allows you to get the times that the photographer / videographer wants to have
If you want to add glass in front of your lens, make sure it is of the highest optical and build quality.

The Variable NiSi filter is also available in intensity from 1.5 to 5 Stops, perfect together with the 5-9 Stop to have a wide range from 1.5 to 9 Stops with only two filters.

* The Variable NiSi filter is considered the best on the market, at the right price, thanks to the possibility of buying the product directly from the manufacturer. In any case, all the Vario filters are not true ND filters, but always formed by two treated surfaces which in contrast reduce the light entering the sensor. For this reason, even the best variable filter is never free from some small defects such as: uniformity of absorption and the presence of slightly darker or lighter areas. We always recommend the use of variables as a practical alternative to ND filters and not as a total replacement. The advice to use only high quality ones such as the Vario-ND NiSi remains valid.
