Overview

The NiSi 55084 82mm ND64 + CPL filter is a dual-function optic built for landscape and long-exposure photography. It merges a 6-stop neutral density filter (ND64, density 1.8) with a circular polarizer into a single unit, eliminating the image quality compromises that come from stacking two separate filters. The 6-stop light reduction enables dramatically slower shutter speeds — turning choppy water into smooth silk or streaking clouds across the sky — while the rotatable CPL layer independently cuts reflections and glare from water, foliage, and other non-metallic surfaces to deepen contrast and color saturation.

NiSi uses high-definition optical glass treated with their proprietary nano IR coating, which serves multiple purposes: it blocks infrared light that causes the unnatural color casts common in cheaper ND filters, repels water and oil for easy field cleaning, and resists scratches from everyday handling. The ultra-slim frame minimizes the risk of vignetting on wider lenses, while the knurled edges allow precise CPL adjustment even when wearing gloves in cold conditions. For landscape photographers who routinely use both ND and polarizing filters, this combined design reduces gear, simplifies workflow, and maintains optical integrity in a single 82mm package.

Key Features

Circular polarizer can be rotated to eliminate reflections and glare on non-metallic surfaces

Pros & Cons

👍 Pros

  • Combines ND64 and CPL into a single filter, reducing the need to stack two separate filters and avoiding additional image degradation.
  • Independently rotatable polarizer ring provides full control over reflection and glare reduction.
  • Nano IR coating blocks infrared contamination and maintains accurate, natural colors in long exposures.
  • Ultra-slim frame with knurled edges makes it easy to mount, remove, and rotate the CPL even with gloves.
  • Waterproof, scratch-resistant coating simplifies cleaning and protects the glass during outdoor use.

👎 Cons

  • A combined ND+CPL filter cannot be separated, so you lose the flexibility of using each filter independently.
  • The fixed 6-stop density may be too strong or too weak for certain lighting conditions where a variable ND would offer more versatility.
  • 82mm thread size does not directly fit smaller lenses without step-up adapter rings.
  • Premium NiSi glass and coatings come at a higher price than budget ND or CPL filters purchased separately.

Frequently Asked Questions

Yes. The CPL ring on this filter rotates independently, allowing you to dial in the exact amount of polarization you want while the ND64 density remains constant at 6 stops.
NiSi's nano IR coating is designed to block infrared light and minimize color shifts. The filter maintains natural color reproduction, which is a common concern with lower-quality ND filters that can introduce warm or magenta casts.
The ultra-slim frame design is intended to reduce vignetting, but on very wide focal lengths (below roughly 24mm on full frame), some corner vignetting may still occur depending on the lens.
The ND64 designation means a density of 1.8, which translates to a 6-stop reduction in light entering the lens. This allows you to use significantly slower shutter speeds for motion blur effects in daylight conditions.
NiSi's nano coating is waterproof, scratch-resistant, and repels oils and fingerprints, making the filter surface easier to clean in the field and more resistant to everyday handling damage.
