NiSi Square Nano IRND 150X150mm ND256 8Stops

NiSi Square Nano IRND 150x150mm ND256 (8 Stops) – Nano Coating with IR Protection

The NiSi Square Nano IRND 150x150mm ND256 provides an 8-stop light reduction while protecting colours from infrared contamination. It uses high-definition optical glass and double-sided nano coating to preserve image detail during long exposures. Photographers who need longer shutter times and accurate colours will benefit from this filter.

Designed for Landscape Photography and Long Exposures

This square ND filter is specially designed for landscape photographers who require extended exposure times to capture motion and atmosphere. Because it reduces light evenly, it allows you to use longer shutter speeds without changing the scene’s colour balance.

Optical Quality and Coatings

NiSi builds this filter from environmental optical lens glass (H-K9L), not resin. The high-definition glass maintains image clarity and detail. Additionally, NiSi applies Nano Coating on both sides of the glass. This double-sided nano coating reduces reflections and helps repel water and oil, making the filter easier to clean and maintain.

Infrared (IR) Protection for True-to-Life Colour

Neutral density filters can expose the camera sensor to more infrared light, which sometimes produces unwanted red colour casts at small apertures. NiSi added an infrared protection coating layer to this IRND filter to reduce that infrared contamination. As a result, the filter helps restore natural, vibrant colours when shooting long exposures or using small apertures.

Available Densities

This specific product is the ND256 version, providing 8 stops of light reduction. NiSi also offers the Nano IR Neutral Density filters in the 150x150mm size across multiple density steps for different creative needs:

FAQ

Question: Is this filter suitable for landscape photography?

Answer: Yes. NiSi designed the 150x150mm Nano IRND filters specifically with landscape photographers in mind, enabling longer exposures while preserving colour and detail.

Question: How does the IR protection affect my images?

Answer: The infrared protection coating reduces unwanted infrared light that can cause red colour casts at small apertures. This helps the filter deliver truer, more natural colours during long exposures.

Question: What materials and coatings are used?

Answer: The filter uses high-definition environmental optical glass (H-K9L), not resin. It features nano coating on both sides for low reflection and water/oil repellency, plus an infrared protection layer to maintain accurate colours.

Question: Which ND strengths are available in 150x150mm size?

Answer: Aside from the ND256 (8 stops) model, NiSi offers 150x150mm Nano IRND filters in 2, 3, 4, 5, 6, 10 and 15 stop densities to match different creative needs.
