GND Filter 150x170mm GND8 Hard (0.9) 3 apertures

NiSi 150x170mm gray graduated filters (GND) are an indispensable tool for landscape photography. Thanks to the use of these filters, you can bypass the limits of your camera’s dynamic range while capturing details in the light and dark areas of the scene. They are made of high-quality optical glass and allow you to capture every detail in your photos, without distortions or color changes. Gray graduated filters are darkened at one end and transparent at the other. In the center of the filter, these two surfaces blend into each other, from dark to clear.

NiSi GND8 Hard (0.9) Nano IR 3 apertures 150x170mm

The addition of Nano®

indicates

the use of a special nano-coating. IR is a coating that blocks infrared light, and therefore prevents the magenta color cast that is often present. While GND8, (0.9) and 3 apertures with three different designations describe the light absorption value of the filter. The dimension is 150x170mm and 2mm thickness, so the filter is also compatible with filter holders from other manufacturers that support this standard and do not have high manufacturing tolerances. We recommend the use of a NiSi S5 filter holder with integrated polarizing filter or a NiSi “Classic” filter holder of the Q series] if you do not want to use a polarizing filter.

"Hard" transition

The Hard filters have a hard transition from dark to clear. This type of filter is best for scenes that have a clearly visible transition from foreground to sky. It is best used on landscapes where there are no elements overhanging the horizon, such as seaside shots overlooking the open ocean.

Forget resin filters

The NiSi filters are all made of high quality optical glass to capture the finest details and to be able to use them permanently with consistent quality. The special nano-coating on both sides minimizes unwanted reflections and gives the NiSi neutral density filters the property of being water repellent and very easy to clean.

Unique on the market

Thanks to the very high color fidelity without color cast, you can finally say goodbye to strong color corrections in post-processing.
NiSi optical glass is not a classic B270 glass, but it is a high quality glass that is also used by the major manufacturers of photographic lenses especially for the finest optical elements. NiSi filters do not affect the image, allowing you to realize the full potential of your lens and photo sensor. In addition to **IR-** blocking, NiSi filters also block ultraviolet (UV) light for even more accurate color fidelity.

Weatherproof

The Nano® coating gives the filter the ability to repel water and oils. This facilitates cleaning even under extreme conditions or splashes of seawater, for example. The finishing of the edges and the rounded corners of our filters improve durability and handling.
