NiSi Square Nano IRND 150x150mm ND16 4Stops

NiSi Square Nano IRND 150x150mm ND16 (4-Stop) – Nano coating with IR protection for true-to-life colors

This NiSi Square Nano IRND 150x150mm ND16 (4-stop) filter gives you neutral density control while protecting color fidelity. It uses high-definition optical glass and double-sided nano coating to maintain image detail and resist water and oil. In addition, the IR protection layer reduces infrared contamination that can cause an unwanted red cast at smaller apertures.

Designed use and creative benefits

NiSi designed this square filter with landscape photographers in mind. By reducing light by four stops, it lets you use longer exposures for motion blur, smooth water, or reduced depth-of-field in bright conditions. At the same time, the IR coating helps retain natural, vibrant colors that neutral density use can otherwise alter.

Material and coatings

• High-definition optical glass (not resin) for image clarity and detail retention.
• Double-sided Nano Coating to reduce reflections and repel water and oil.
• Infrared protection coating to minimize IR contamination and restore natural color.

Key optical characteristics

NiSi states that these ND filters keep color neutral while keeping reflections low and avoiding vignetting. The filter construction aims for ultra low colour cast, ultra low reflection, and high definition results so you can maintain image quality during longer exposures.

Available stops and sizes

This product is part of NiSi’s Square Nano IR Neutral Density range. The 150x150mm size is available in several density steps, and the ND16 corresponds to a 4-stop reduction. Other available stops in the same 150x150mm series include:

• 2 stop
• 3 stop
• 4 stop (ND16)
• 5 stop
• 6 stop
• 10 stop
• 15 stop

Smart FAQ

Question: What does ND16 (4-stop) mean for my exposure?
Answer: ND16 reduces incoming light by four stops, allowing longer shutter speeds or wider apertures in bright conditions for creative effects such as motion blur or shallower depth of field.

Question: Will this filter change the colors in my image?
Answer: Neutral density filters are intended not to affect image coloration. This NiSi Nano IRND also includes an infrared protection layer to minimize any IR-induced red cast and help maintain natural, vibrant colors.

Question: What materials and coatings does the filter use?
Answer: The filter uses high-definition optical glass (H-K9L), double-sided Nano Coating for low reflection and water/oil repellence, and an infrared protection coating to reduce IR contamination.

Question: Is this filter suitable for landscape photography?
Answer: Yes. NiSi specifically designed the Square Nano IRND 150x150mm range for landscape photographers, offering long-exposure control while aiming to preserve detail and color fidelity.
