SKU CH-QMZT-K553N

72mm round neutral-density filter with 15-stop light reduction for ultra-long daytime exposures

  • 15-stop light reduction for extended daylight exposures
  • ND32000 density enables 3–6 minute shutter speeds
  • IR coating suppresses colour cast in long exposures
  • Nano coating protects optical clarity on glass
  • Ultra-thin 72mm frame prevents vignetting on wide lenses

72mm 15-Stop ND Filter for Landscape Photographers

The NiSi 72mm ND32000 (4.5) PRO Round ND Filter provides a 15-stop light reduction for long exposure photography. It is designed for landscape photographers who want to capture motion blur in bright conditions using a 72mm lens thread. This neutral density filter uniformly darkens the image without shifting natural colours. It is not suited for shooters who need variable density control or a filter thread size other than 72mm.

Optical Glass Construction with Nano and IR Coatings

The filter uses high-quality optical glass with a nano coating to preserve sharpness and clarity. An IR coating reduces infrared colour cast to maintain true-to-life colour rendition. The ultra-thin frame with a matt black superfine frosted finish minimises reflections. These combined coatings and construction manage light transmission cleanly during the extended exposures this density requires.

Fixed 15-Stop Density Enables Multi-Minute Exposures

The fixed ND4.5 density facilitates exposures of 3 to 6 minutes in broad daylight for creative motion effects. This single density replaces the need to stack multiple filters for equivalent light reduction. The round screw-on design mounts directly to compatible 72mm threads without a separate holder system. Buyers who require different densities for changing light must purchase additional fixed filters.

Questions about this item

How do I mount the 72mm filter without cross-threading the ultra-thin frame?

Align the threads carefully and turn clockwise with light pressure until the matt black superfine frosted frame seats flush; the ultra-thin profile leaves little margin for misalignment, so never force it.

What cleaning routine preserves the nano and IR coatings on the optical glass?

Blow off dust first, then wipe gently with a microfibre cloth and dedicated lens fluid; avoid abrasive tissues or circular scrubbing that can degrade the nano coating and IR coating over time.

At what exposure length does infrared leak become visible despite the IR coating?

The IR coating suppresses colour cast during the 3 to 6 minute daylight exposures the ND32000 is designed for; beyond that range, infrared accumulation may reappear and require white-balance correction in post.
