NiSi Filter IRND1000 Pro Nano Huc 39mm

NiSi Filter IRND1000 Pro Nano Huc 39mm – 10-stop Neutral Density with IR Protection

The NiSi IRND1000 Pro Nano Huc 39mm is a 10-stop neutral density filter designed to reduce light entering the lens while preserving image detail and colour. It uses high-quality optical glass with nano coating and an added infrared protection layer to maintain natural colour balance. The ultra-thin brass frame measures 3.5mm, allowing use on wide-angle lenses while reducing the risk of vignetting.

Key benefits

• Reduces exposure by 10 stops (Neutral Density 3.0), enabling long exposures and wider apertures in bright conditions.
• IR coating helps eliminate infrared light that can cause unwanted colour shifts, bringing back a more natural colour rendition.
• Nano coating preserves image detail and resists loss of sharpness from reflections or surface issues.
• Ultra-thin brass frame (3.5mm) with a matt black superfine frosted finish reduces reflections and fits well on wide-angle lenses to help avoid vignetting.

How and when to use this ND filter

Attach the NiSi IRND1000 to uniformly reduce the amount of light entering your lens. Use it when you need greater motion blur, for example when smoothing water or conveying movement, because it lets you use a slow shutter speed without overexposing. Alternatively, use it to shoot with a large aperture in bright light to achieve shallow depth of field.

The filter also helps when the contrast between highlights and shadows is too great for a good exposure. In such scenes, the uniform light reduction can make it easier to record detail across the frame without changing camera settings that affect depth of field or motion.

Design and construction

The filter glass is made from high-quality optical glass. The frame is constructed from brass and kept ultra thin at 3.5mm. This thin profile makes the filter suitable for super wide-angle lenses by helping to avoid vignetting. The frame features a matt black superfine frosted finish and a top smooth surface finish for reduced reflections and a refined look.

Coatings and optical characteristics

The NiSi IRND1000 includes a nano coating to protect glass surfaces and maintain detail. It also includes an infrared (IR) protection coating layer that reduces infrared light passing through the lens, which helps reduce colour cast caused by IR contamination. The ND3.0 density provides a 10-stop reduction in light while maintaining a neutral colour response without introducing a colour cast.

FAQ

question: How many stops of light does the NiSi IRND1000 reduce?

Answer: The filter is ND 3.0, which provides a 10-stop reduction in light, allowing long exposures or wider apertures in bright conditions.

question: Will this filter change the colours in my images?

Answer: The filter is described as providing no colour cast. In addition, the IR protection coating helps eliminate infrared light that can otherwise cause colour shifts, so it aims to preserve natural colour rendition.

question: Is the filter suitable for wide-angle lenses?

Answer: Yes. The frame is ultra thin (3.5mm) and made of brass, which helps the filter fit closely and reduces the risk of vignetting on super wide-angle lenses.

question: What do the nano and IR coatings do?

Answer: The nano coating helps maintain surface quality and image detail, while the IR coating reduces infrared light entering the lens to help bring back natural colour, both contributing to a cleaner optical performance.

question: How does this ND filter help with exposure and motion effects?

Answer: By uniformly reducing the amount of light entering the lens, the filter enables slower shutter speeds for motion blur and allows the use of larger apertures in bright light for shallow depth of field, without overexposing the image.
