NiSi Square Nano IRND 100x100mm ND16 4Stops

NiSi Square Nano IRND 100x100mm ND16 – 4 Stops for longer exposures and true-to-life colors

The NiSi Square Nano IRND 100x100mm ND16 reduces light by 4 stops and lets you use longer exposure times for creative effects. It uses high definition optical glass and a double-sided nano coating to preserve image detail. In addition, the IR protection layer reduces infrared contamination so colors remain natural and vibrant when shooting at smaller apertures.

Key benefits at a glance

• Allows longer exposures to expand creative possibilities without affecting image sharpness.
• IR protection coating reduces unwanted infrared-induced red cast, restoring natural color.
• Double-sided nano coating repels water and oil and reduces reflections for cleaner results.
• Made from high definition optical glass (not resin) to maintain high definition image quality.

Design and image quality

This NiSi Nano IR Neutral Density filter is specially designed for landscape photographers who need precise control over exposure time. Because it is made from environmental optical lens glass (H-K9L) rather than resin, it retains fine detail. The nano coatings on both sides reduce reflections and make the surface water- and oil-repellent, which helps keep the filter clean in the field.

Neutral density filters, by definition, do not change image coloration. However, using an ND filter can increase the camera’s sensitivity to infrared light and cause a red color cast at small apertures. NiSi addresses this by applying an infrared protection layer that helps eliminate that infrared light entering the lens, bringing back natural colors in your photos.

FAQ

Question: Will this ND filter change the colors in my images?
Answer: Neutral density filters are designed not to affect coloration. Additionally, this NiSi Nano IRND includes an infrared protection coating to reduce infrared-induced red cast and help preserve natural color.

Question: Is the filter made of glass or resin?
Answer: The filter is made from high definition optical glass (not resin), specifically environmental optical lens glass (H-K9L), to maintain image detail.

Question: How does the nano coating help in practical use?
Answer: The double-sided nano coating reduces reflections and repels water and oil, making the filter easier to clean and more reliable in varying outdoor conditions.

Question: Will I experience vignetting with this filter?
Answer: The filter is specified to produce no vignetting when used as intended.
