Overview

The NiSi HUC PRO Nano IR ND64 52mm is a 6-stop neutral density filter for photographers who need real-world color accuracy from their ND filtration, not just light reduction. The 1.8 optical density reduces light by a factor of 64, enabling exposure times that produce smooth water surfaces, blurred crowd movement, and dynamic cloud drag in landscape and architectural work. What the IR-blocking coating adds is technically significant: standard ND filters can permit residual infrared light to reach the sensor, producing a color cast particularly problematic in small-aperture, long-exposure scenarios. NiSi's IR correction eliminates this leakage, making output cleaner with less post-processing correction required.

The filter is built on a slim aluminum frame with knurled edges and double-sided threading. Slim profile construction minimizes vignetting when the filter is used alone or stacked with a UV or CPL on moderate wide-angle lenses. Nano waterproof coating on the glass surface repels water and resists fingerprints — which matters during waterfall shoots or beach sessions where cleaning cloths aren't always at hand. At 52mm, this is sized for smaller prime lenses and compact zooms. Photographers standardizing a filter system across multiple larger-diameter lenses will need dedicated filters or step-up rings for each size.

Key Features

PERFECT FIT: The NiSi ND64 IR filter is meticulously crafted to effortlessly fit lenses and adapters equipped with a standard filter thread. Simply locate the 'ø' symbol on your lens or lens cap to confirm compatibility with this 52mm ND filter. Ideal for discerning photographers, it seamlessly integrates into your camera gear, ensuring optimal performance and convenience. Elevate your photography with this versatile neutral density filter, designed to meet the demands of professionals.

SLIM, STACKABLE DESIGN FOR EASY USE: Designed with a slim aluminum frame, double-sided threading, and knurled edges, the NiSi ND64 filter is easy to install, stack, and combine with other ND filters, UV filters, or CPL filters for maximum versatility. This lightweight yet durable 52mm ND filter ensures a secure fit and effortless handling, making it an essential tool for photographers using neutral density filters in creative setups.

FULL CREATIVE CONTROL WITH 6 STOPS: The 1.8 density from the ND64 provides a 6-stop reduction of light entering the lens, enabling precise exposure control for creative effects like motion blur, smoother water flow, and enhanced depth of field. This neutral density filter is perfect for capturing dynamic long-exposure shots. It is ideal for professionals and hobbyists to use this 52mm ND filter or experiment with their ND cameras for artistic results.

ADVANCED INFRARED PROTECTION: The NiSi ND64 filter features an advanced infrared protection coating that eliminates unwanted red color casts caused by small apertures, ensuring vivid tones and true-to-life colors. This ND filter 52mm is a high-quality IR camera filter, ideal for achieving consistent color balance in every shot, making it a trusted tool for photographers using infrared camera lens filters or neutral density filters for creative and professional photography.

DURABLE, WATERPROOF, AND EASY TO MAINTAIN: Built with a robust nano waterproof coating, this ND camera filter resists scratches, water, and fingerprints, ensuring durability in harsh outdoor environments. The ND filter 52mm is easy to clean and maintain, providing long-lasting performance for photographers. This nano filter is essential for professionals needing reliable, high-quality neutral density filters for photography.

Pros & Cons

👍 Pros

  • IR-blocking coating eliminates the reddish color cast that affects unprotected ND64 filters at small apertures, preserving accurate color in long-exposure results
  • Slim aluminum frame minimizes vignetting risk when stacking this filter with a UV or CPL on medium telephoto lenses
  • Double-sided threading allows the filter to accept additional filters on top, building a modular filter system from a single slim base
  • Nano waterproof coating repels water and resists fingerprint adhesion, reducing cleaning frequency during waterfall or coastal shooting sessions
  • 6-stop density opens up creative shutter speed options — silky water, cloud motion blur — that require significant light reduction to achieve at base ISO in daylight

👎 Cons

  • 52mm is a smaller filter size — photographers with lenses of multiple diameters will need separate filters or step-up rings for each, as this filter doesn't cover larger front elements
  • The slim frame provides less grip surface than standard-thickness filters during installation and removal, particularly with gloved hands in cold conditions
  • Knurled edges on a slim frame provide limited torque for unscrewing a stuck filter after over-tightening — a filter removal wrench may be needed
  • At 6 stops, this filter doesn't reach the 10-stop range needed for daytime exposures measured in minutes — additional or denser ND filters are required for ultra-long-exposure work
  • No hard protective case included — separate storage is needed to prevent scratches to the optical glass and nano coating during transport

Frequently Asked Questions

Without IR protection, dense ND filters allow infrared light to pass through, creating a reddish or magenta cast in shadows and midtones — especially with small apertures or longer exposures. The NiSi's IR coating blocks this leakage. On cheaper ND filters without IR correction, you may need to correct the cast in post, which degrades color accuracy.
Yes. The slim aluminum frame features double-sided threading, allowing the NiSi ND64 to be stacked with UV or CPL filters. Adding multiple filters increases vignetting risk on wide-angle lenses — test at your widest focal length before committing to a stacked setup.
Look for the diameter symbol (ø) printed on the lens barrel or inside the lens cap. If it reads ø52, this filter fits. Filter diameter is distinct from focal length or aperture designation.
In bright daylight at ISO 100 and f/8, a base exposure might be around 1/500s. Six stops extends that to approximately 1/8s — enough to smooth fast-moving water into silk or blur cloud movement. For exposures in the minutes range, a denser ND or stacked filters are required.
The anti-reflective component of the nano coating actually reduces internal flare and ghosting compared to an uncoated glass element. No sharpness penalty is introduced by the coating — optical quality is determined by the glass itself, which NiSi specifies as premium optical grade.
