NiSi Square Nano IRND 150x150mm ND8 3Stops

NiSi Square Nano IRND 150x150mm ND8 (3 Stops) – Nano-coated high-definition optical glass with IR protection

This NiSi Square Nano IRND 150x150mm ND8 (3 stops) filter gives landscape photographers a reliable way to extend exposure time while maintaining natural colors. It uses high definition optical glass (not resin) and features double-sided nano coating technology. In addition, NiSi added an infrared (IR) protection coating to prevent unwanted color shifts caused by infrared light.

Designed for landscape photography — what it does

Use this filter to lengthen shutter speeds and unlock creative effects such as smoother water, blurred motion and controlled highlights. The neutral density function reduces incoming light without altering the scene’s color balance. Meanwhile, the IR protection layer combats the red cast that can appear when shooting at small apertures, helping to preserve true-to-life, vibrant colors.

Core features

• High definition Optical Glass (not resin) for sharp image quality.
• Double-sided Nano Coating to protect detail and reduce reflections.
• IR protection coating that reduces infrared contamination and restores natural color when shooting at small apertures.
• Allows longer exposure times to enable creative landscape techniques.
• Ultra low colour cast and ultra low reflection for faithful color reproduction and improved contrast.
• No vignetting when used as intended in 150x150mm systems.
• Water and oil repellent surface treatment for easier maintenance and cleaning.
• Made from Environmental Optical Lens glass (H-K9L).

How the Nano IRND works in practice

The neutral density element cuts light evenly across the frame so you can increase exposure time without shifting the perceived coloration. However, regular ND filters can allow infrared light to affect the image, producing a reddish cast at small apertures. NiSi’s Nano IRND adds an IR protection layer that blocks this infrared light, so you retain natural color reproduction even during long or stopped-down exposures.

Available densities

The NiSi Nano IR Neutral Density filters in 150x150mm size are available in multiple stop options to match different creative needs. The available aperture steps are:

FAQ

Question: Is this NiSi Square Nano IRND suitable for landscape photography?
Answer: Yes. The filter is specially designed for landscape photographers and helps you achieve longer exposures while preserving natural color and detail.

Question: Will the filter change my image colors?
Answer: Neutral density filters do not affect the coloration of the image. Additionally, NiSi’s IR protection coating reduces infrared-induced red casts that can occur at small apertures, helping maintain true-to-life vibrant color.

Question: What material and coatings does this filter use?
Answer: The filter is made from high definition optical glass (not resin) and features nano coating on both sides. The surface is water and oil repellent, and the filter includes an IR protection coating layer to minimize infrared contamination.

Question: Which stop options are available in the 150x150mm series?
Answer: The 150x150mm NiSi Nano IRND series is available in 2, 3 (ND8), 4, 5, 6, 10 and 15 stop versions, so you can choose the density that fits your creative needs.

Question: What practical benefits can I expect when using the ND8 (3 stop) version?
Answer: The ND8 (3 stop) version reduces incoming light by three stops, allowing moderately longer exposures for creative effects like smoothing motion and controlling highlights, while keeping color accuracy through the IR protection and nano coatings.
