Overview

The NiSi 77mm HUC PRO Nano IR ND64 is a landscape photographer's working filter — the piece you screw on when the light is gorgeous but the shutter speed your f/11 aperture demands is too fast to capture the mood you're after. Six stops of light reduction opens up creative territory that a bare lens simply can't reach: rivers become silk, waves turn to mist, and moving clouds trace arcs across a long sky. What separates this filter from cheaper ND options is the IR correction coating, which keeps that creative control honest — your midtones stay gray, your whites stay white, and your sky doesn't drift toward magenta when you stop down tight.

The filter is built around H-K9L optical glass in a slim aluminum alloy frame, and the construction feels like it belongs on a serious kit. The knurled edges allow confident grip for mounting and removal even when hands are cold and damp from a dawn coastal shoot. The nano coating repels water and fingerprints with the predictable efficiency of quality hydrophobic glass — a quick wipe puts it back to shooting-ready fast. Whether you're mounting it solo for a long exposure or stacking it behind a CPL for combined polarization and density control, the double-sided threading integrates cleanly into your workflow without binding or misalignment.

Pros & Cons

👍 Pros

  • The IR reduction coating eliminates the red color cast that plagues uncorrected ND filters at small apertures, delivering neutral tones straight out of camera with minimal post-correction needed.
  • Six stops of density is the practical sweet spot for landscape work — enough to achieve silky water and cloud motion in bright daylight without crossing into the ultra-long exposures that require bulb mode.
  • The nano waterproof and scratch-resistant coating holds up to coastal spray, rain, and repeated cleaning across extended outdoor sessions without developing haze or micro-scratches.
  • Slim double-sided threading makes stacking with a CPL or UV filter straightforward, and the knurled edges give a reliable grip even in cold or wet gloved hands.
  • H-K9L optical glass maintains sharpness and color neutrality across the frame — you don't lose resolution at the corners in the way budget filters tend to soften.

👎 Cons

  • At 77mm, this filter doesn't cover wider filter thread sizes — photographers working with 82mm or 95mm lenses need a different size, and step-up ring combinations can introduce vignetting on wider focal lengths.
  • Stacking two filters can cause vignetting at focal lengths below approximately 24mm on full-frame bodies — ultra-wide landscape shooters may need a square filter system instead.
  • Six stops, while versatile, isn't enough for extremely bright midday shooting with very wide apertures — achieving 10–15 second exposures in full sun requires additional ND stacking.
  • The slim frame, while excellent for stacking, can be fiddly to grip when mounting or removing in cold field conditions with thick gloves.

Frequently Asked Questions

The practical answer is yes — without IR correction, a standard ND filter at small apertures like f/11 or f/16 will introduce a reddish-magenta cast that requires correction in post. The NiSi IR coating blocks the near-infrared wavelengths responsible for this shift, so your whites stay neutral and your sky retains its true blue tone straight out of camera. It's most noticeable in landscape work with large sky areas or in any scene with bright highlights.
The double-sided threading on the slim aluminum frame is specifically designed for stacking. A CPL combined with this ND64 gives you both polarization control and a 6-stop exposure reduction simultaneously — useful for shooting waterfalls in direct sun or managing glare on water during bright midday hours. Be aware that stacking two slim filters can introduce slight vignetting at focal lengths shorter than about 24mm on full-frame.
At base, 6 stops means you multiply your unfiltered shutter speed by 64. If your metered exposure without the filter is 1/500s, with the ND64 mounted you'd be working at approximately 1/8s. In bright midday sun that opens up 1–4 second exposures — enough to smooth flowing water or show motion blur in moving clouds without needing a fully opaque filter.
The nano waterproof coating is hydrophobic and oleophobic, so most dust and fingerprints wipe off easily with a dry microfiber cloth. For stubborn smears, a small amount of lens cleaning solution on a fresh cloth works well. Avoid paper towels or rough fabrics — the coating is durable against field conditions but not immune to abrasion from coarse materials.
AF operates normally with the filter mounted — there's no mechanical interference. However, 6 stops of light reduction will noticeably slow AF in dim conditions or on lenses with slower maximum apertures. For long-exposure landscape work where you'd be using live view and manual focus anyway, this is a non-issue. For event or street shooting with an ND for creative blur, factor in the reduced light when choosing your AF mode.
