NiSi GND 100x150mm ND8 (0.9) 3 Stop Medium

NiSi Graduated Neutral Density Filters (GND) are the indispensable tool for any landscape photographer by allowing you to overcome the limits of the dynamic range of your camera, while simultaneously capturing details in the light and dark areas of the scene. Made of high quality lens grade optical glass, they will allow you to capture every little detail in your images without distortions or colour alterations. Perfect when combined with a NiSi filter holder, NiSi graduated neutral density (GND) filters are compatible with relevant third-party that support 2mm thick filters.

Medium transition filters have an intermediate transition between the light and dark parts; less clear than Hard filters and more accentuated than Soft filters. These are essential GND filters for and photographer’s kit bag and are excellent on their own in the event of a line of a composition without clearly defined light and dark areas.  They are also great in combination with Hard or Soft GND filters.

ND8, 0.9 and 3 stops are different ways to indicate the light absorption value of the filter in question.


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 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 dominant colours, 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.
