NiSi Filter IRND 64+CPL Pro Nano 72mm

NiSi Filter IRND 64+CPL Pro Nano 72mm – 6-stop ND combined with Circular Polarizer in one

The NiSi IRND 64+CPL Pro Nano 72mm gives you a six-stop neutral density effect together with a circular polarizer in a single, multifunctional filter. By combining CPL and ND in one element you avoid stacking filters on top of each other. As a result, you maintain image sharpness, avoid colour casts and reduce the risk of vignetting.

Key features

• Six-stop ND effect (IRND 64) for longer exposures and wider apertures in bright conditions.
• Integrated Circular Polarizer (CPL) so you do not need to stack a separate CPL on top of an ND filter.
• No colour cast for true colour matching between shots.
• IR coating combined with optical glass for improved infrared control.
• Waterproof and grease-proof surface treatments to resist moisture and fingerprints.
• Ultra High Definition glass that preserves fine detail with no visible loss of sharpness.
• Ultra slim frame, only 4.9mm, to reduce light falloff and minimise vignetting.
• 72mm filter thread size to fit lenses with a 72mm front thread.

Why choose this filter

This filter suits photographers and filmmakers who want the control of both an ND and a polarizer without the drawbacks of stacking two separate filters. Because the CPL and ND are combined, you can control reflections and reduce light simultaneously while keeping colour fidelity and sharpness. The slim 4.9mm frame helps reduce edge darkening, which is particularly important on wide-angle lenses.

Practical use cases

• Shoot long exposures in bright daylight without changing ISO or stopping down excessively.
• Reduce reflections on water, glass and foliage while also cutting light by six stops.
• Avoid stacking filters to keep a slimmer optical path and lower the chance of vignetting.
• Use outdoors where water and grease resistance help maintain filter performance in variable conditions.

Specifications

Care and handling notes

The filter's waterproof and grease-proof treatments help maintain performance during outdoor use and handling. Because the filter combines CPL and ND functions, you can reduce gear and avoid stacking, which also helps keep your setup slim and manageable.

FAQ

Question: Will this filter fit my lens?

Answer: This product is a 72mm filter and fits lenses with a 72mm front thread. Ensure your lens thread size matches 72mm before purchase.

Question: Does the combined CPL and ND cause a colour cast?

Answer: No. The NiSi Pro Nano is specified to produce no colour cast, helping you achieve true colour matching across shots.

Question: How strong is the neutral density effect?

Answer: The IRND 64 provides a six-stop ND effect, allowing longer exposures or wider apertures in bright conditions without additional exposure adjustments.

Question: Will using the combined filter create vignetting when compared to stacking separate filters?

Answer: Because the filter integrates CPL and ND in one element and features an ultra slim 4.9mm frame, it reduces the need to stack filters and helps minimise light falloff and vignetting, especially on wide-angle lenses.
