NiSi Filter IRND8 Pro Nano Huc 72mm

NiSi Filter IRND8 Pro Nano Huc 72mm – 3-stop neutral density with IR protection

The NiSi IRND8 Pro Nano HUC 72mm is designed for landscape photographers and videographers who need reliable light reduction without altering colors. It provides a neutral density of 0.9, which equals a 3-stop reduction in exposure, while the added IR coating helps return natural color by reducing infrared contamination.

Key benefits and intended use

This filter reduces the amount of light entering your lens evenly, so you can use larger apertures or slower shutter speeds to capture motion blur, longer exposures, or control depth of field. It is especially useful when the contrast between highlights and shadows makes correct exposure difficult. Photographers and videographers working in landscapes will find the IRND8 effective for creative long-exposure shots and controlled video exposure.

Optical quality and construction

NiSi manufactures the IRND8 from high-quality optical glass and applies a nano coating to protect image detail and improve handling. The frame is aluminium and measures only 3.5mm in thickness. Because of this ultra-thin profile, the filter fits well on very wide-angle lenses and helps avoid vignetting that thicker filters might cause.

Coatings and finish

The filter includes multiple surface treatments to improve performance and maintenance. For color fidelity, an infrared protection coating reduces IR light reaching the sensor to help bring back natural colors. A nano coating makes the glass highly resistant to water and oil, which in turn makes the filter extremely easy to clean. Additionally, the frame uses a matt black superfine frosted finish with a top smooth surface finish for reduced reflections and robust handling.

How it affects exposure and image characteristics

Attaching the NiSi IRND8 Pro Nano uniformly decreases incoming light by 3 stops. As a result, you can slow the shutter speed or open the aperture for creative effects while maintaining correct exposure. Importantly, the filter is designed to avoid introducing a color cast, so your images retain neutral coloration when used properly.

Practical tips for use

First, attach the filter to the 72mm lens thread and check for vignetting, especially on ultra wide-angle lenses. Second, when shooting long exposures or video in bright light, compensate by 3 stops to maintain proper exposure. Third, clean the filter with a soft cloth when needed—thanks to the nano coating it resists water and oil and is very easy to maintain.

Frequently Asked Questions

• Question: Will this filter change my color balance or cause a color cast?

  Answer: The NiSi IRND8 is designed as a neutral density filter and explicitly states "No color Cast." Additionally, it includes an IR coating to reduce infrared light, which helps bring back more natural color when compared to filters without infrared protection.

• Question: Is this filter suitable for wide-angle lenses without vignetting?

  Answer: Yes. The filter's aluminium frame is ultra thin at 3,5mm, which makes it suitable for use on super wide-angle lenses and helps avoid vignetting that thicker filters might introduce.

• Question: How many stops of light does the filter reduce?

  Answer: The neutral density value is 0.9, which corresponds to a reduction of 3 stops of exposure.

• Question: How do I clean and maintain the filter?

  Answer: The filter has a nano coating that makes the glass highly resistant to water and oil, so it is extremely easy to clean. Use a soft, lint-free cloth and gentle cleaning solutions as needed to remove smudges without scratching the surface.
