NiSi Filter IRND64 Pro Nano Huc 46mm

NiSi Filter IRND64 Nano Huc 46mm – 6-Stop ND with Ultra-Thin 3.5mm Frame and IR Coating

The NiSi Filter IRND64 Nano Huc 46mm is a 6-stop neutral density (ND) filter designed for photographers and videographers who need to reduce light to achieve slower shutter speeds or larger apertures. It suits landscape and portrait work as well as video shooting where you want to control exposure and motion blur while preserving image quality.

How the filter affects exposure and creative control

This ND64 filter uniformly reduces the amount of light entering the lens by 6 stops. That reduction lets you select a longer shutter speed to create motion blur or choose a larger aperture to achieve a shallower depth of field. Landscape photographers and videographers can use the filter to capture slower shutter effects, while portrait photographers can benefit from wider apertures in brighter conditions.

Optical quality and coatings

The filter uses high quality optical glass and a nano coating that preserves sharpness and resolution. The nano coating also repels water and grease, helping to keep the surface cleaner during shooting. NiSi specifies that the filter has no effect on color rendition.

In addition, the filter features an infrared (IR) coating. This IR coating helps eliminate infrared light and prevents color casts that can appear during long exposures, maintaining neutral color balance in challenging lighting.

Design for wide-angle lenses and practical use

The matt black filter frame is ultra thin, measuring only 3.5mm. This slim profile reduces the risk of vignetting on super wide-angle lenses, making the filter suitable for wide-angle landscape work. The 46mm thread size fits lenses with a 46mm filter thread.

Features

• Reduces exposure by 6 stops

FAQ

Question: Is this filter suitable for super wide-angle lenses?
Answer: Yes. The matt black frame is ultra thin (3,5mm), which reduces the risk of vignetting on super wide-angle lenses and makes the filter well suited for wide-angle landscape photography.

Question: Will the filter affect sharpness or color rendition?
Answer: No. The NiSi IRND64 Nano Huc is made from high quality optical glass with a nano coating that preserves sharpness and resolution, and the manufacturer states it has no effect on color rendition.

Question: What does the IR coating do and when does it matter?
Answer: The IR coating helps eliminate infrared light and prevents color casts that can occur during long exposures, so it matters when you use long shutter speeds or shoot scenes where infrared contamination could shift colors.

Question: How does the nano coating help in the field?
Answer: The nano coating repels water and grease, which helps keep the filter surface cleaner while shooting outdoors and makes maintenance easier.

Question: How much light does the filter block?
Answer: The filter reduces exposure by 6 stops, allowing you to use slower shutter speeds or larger apertures than would otherwise be possible.
