NiSi Square Nano IRND 75x80mm ND64 6Stops

NiSi Square Nano IRND 75x80mm ND64 (6 Stops) – Nano IR coating preserves true-to-life colours for long exposures

This NiSi Square Nano IRND 75x80mm ND64 filter reduces incoming light by 6 stops to enable longer exposures and expanded creative control. It combines high-definition optical glass with NiSi’s Nano coating and an infrared protection layer to help maintain natural colours during long exposures, especially useful in landscape photography.

Designed for landscape photographers and long exposures

NiSi designed this square ND filter specifically with landscape photographers in mind. By cutting light by 6 stops, the ND64 version lets you use slower shutter speeds to smooth water, blur moving clouds, or achieve motion effects without changing aperture or ISO. Because the filter is made from optical glass (not resin) and features Nano coatings, it aims to keep image detail sharp during these extended exposures.

Optical construction and coatings

The filter uses high-definition environmental optical lens glass (H-K9L), not resin. Additionally, NiSi applies Nano Coating on both sides. This double-sided treatment repels water and oil, reduces reflections, and preserves fine details. Because neutral density filters can allow infrared light to affect colour at small apertures, NiSi added an infrared protection coating layer to reduce unwanted red cast and help restore natural colours.

Key benefits and practical effects

• Ultra low colour cast and ultra low reflection to maintain colour fidelity and contrast.
• No vignetting when used as intended, helping to preserve even illumination across the frame.
• High definition optical glass for sharp detail across the image.
• Nano coating on both sides that is water and oil repellent for easier cleaning in the field.
• Environmental optical lens glass (H-K9L), not resin, for stable optical performance.

Available densities and sizes

The NiSi Nano IR Neutral Density filters in this family are available in multiple densities and sizes. In the 75x80mm square format, the ND densities offered include 3 stop, 6 stop (ND64), 10 stop, and 15 stop. This product listing refers specifically to the 75x80mm ND64 (6 stops) variant.

FAQ

Question: What does ND64 and 6 stops mean?
Answer: ND64 indicates the filter reduces incoming light by 6 stops. That reduction lets you use slower shutter speeds or wider apertures in bright conditions to achieve creative long-exposure effects.

Question: Will this filter change my image colours?
Answer: Neutral density filters are designed not to affect overall coloration. This NiSi Nano IRND also includes an infrared protection coating to reduce infrared-induced red casts at small apertures, helping to keep colours truer to life.

Question: Is the filter durable and easy to maintain in the field?
Answer: The filter is made from high-definition optical glass (not resin) and features Nano coatings on both sides. These coatings repel water and oil, which makes cleaning easier and helps maintain image quality during outdoor use.

Question: Which photographers will benefit most from this filter?
Answer: The filter is specially designed for landscape photographers and anyone who needs longer exposures for creative effects. Its optical construction and coatings support high-definition results during extended shutter times.

Question: What other ND strengths are available in this size?
Answer: In the 75x80mm square size, NiSi offers 3 stop, 6 stop (ND64), 10 stop, and 15 stop options, allowing you to choose the density that matches your exposure goals.
