NiSi Filter IRND8 Pro Nano Huc 55mm

NiSi Filter IRND8 Pro Nano Huc 55mm – 3-Stop Neutral Density with IR and Nano Coatings

The NiSi IRND8 Pro Nano Huc 55mm is a neutral density (ND) filter designed for landscape photographers and videographers. It reduces incoming light by 3 stops while preserving image detail and natural color. The filter combines an ultra-thin aluminium frame with advanced coatings to minimize vignetting and resist water and oil.

What this filter does

The NiSi Nano IR Neutral Density Filter ND8 uses high-quality optical glass with a nano coating to maintain fine detail. The 0.9 density corresponds to a three-stop reduction in exposure, allowing you to use larger apertures or slower shutter speeds for motion blur or shallower depth of field. Because it is a neutral density filter, it does not affect the coloration of the image under normal conditions.

Why the frame and coatings matter

The filter frame is made from aluminium and measures only 3.5mm in thickness. As a result, the ultra-thin frame fits well on super wide angle lenses and helps avoid vignetting. Additionally, the matt black superfine frosted finish reduces internal reflections. The top smooth finish on the surface improves handling and assembly.

Coatings and optical performance

Two coatings enhance the filter’s performance. First, the IR coating reduces infrared light entering the lens, which helps restore natural color balance in situations where infrared contamination could cause color shifts. Second, the nano coating makes the filter surface very resistant to water and oil, so it repels contaminants and stays easier to clean.

How and when to use it

Attach this ND8 filter when you need to uniformly reduce light entering the lens—especially for landscape scenes with a large contrast between highlights and shadows. Use it to allow slower shutter speeds for motion blur or to open the aperture for greater subject separation, while maintaining overall exposure control.

FAQ

Question: What does ND8 / 0.9 mean and how many stops does it reduce?
Answer: ND8 corresponds to a density of 0.9 and provides a 3-stop reduction in light entering the lens, which lets you use slower shutter speeds or wider apertures while maintaining correct exposure.

Question: Will the filter change my image colors?
Answer: The filter is a neutral density type and is designed not to affect image coloration. In addition, the IR coating helps eliminate infrared contamination that can otherwise cause color cast, helping to restore more natural colors.

Question: Is this filter suitable for wide-angle lenses without causing vignetting?
Answer: Yes. The aluminium frame is ultra-thin at 3.5mm, so the filter sits close to the lens and is specifically designed to reduce the risk of vignetting on super wide angle lenses.

Question: How easy is it to keep the filter clean in the field?
Answer: Very easy. The nano coating repels water and oil, making the surface more resistant to contaminants and simplifying cleaning. The top smooth finish also helps when wiping the filter.
