NiSi 46mm True Color Pro Nano CPL Circular Polarizing Filter (Brass Frame)

The NiSi True Color Pro Nano CPL (Brass Frame) is a professional-grade circular polarising filter, constructed with NiSi's True Color polarising substance and a meticulously crafted brass frame with a matte black finish. It eradicates reflections from non-metallic surfaces, intensifies the depth of the sky, and enhances the saturation in greenery and water. Simultaneously, it maintains the authentic colour equilibrium of your scene, ensuring images require minimal adjustment in post-production and remain faithful to the original view as perceived on-site.

Built for True Color

Many circular polarisers introduce a warm or yellow cast that shifts skin tones and skies. The True Color Pro Nano CPL uses NiSi's True Color polarising material to deliver neutral, accurate colour rendition, making it ideal for landscape, travel, portrait, and product photographers who rely on faithful colour straight out of camera.

Cuts Reflections, Not Quality

Rotate the filter to tame glare from water, foliage, glass, painted surfaces, and wet rocks. Skies deepen, clouds gain contrast, and through-the-surface detail returns to lakes, rivers, and shop windows, all without sacrificing sharpness or introducing colour shift.

Precision-Milled Brass Frame

The ultra-thin brass frame is precision-milled and finished in a clean matte black. Brass threads more smoothly than aluminium and is far less prone to binding on lens threads, even after years of use in the field, making installation and removal effortless.

Knurled Grip for Confident Handling

Knurled sides give your fingers something to bite into when the filter is cold, wet, or being used with gloves. Mounting and removing the CPL becomes quick and predictable, even in awkward shooting positions.

Removable Adjustment Knob

A small, knurled adjustment knob threads into the rotating ring to give you fast, fingertip control over polarisation angle. When you prefer a streamlined profile, or need to stack additional filters, the knob unscrews and stows away in seconds.

Pro Nano Double-Sided Coating

Both surfaces of the optical glass are treated with NiSi's Pro Nano multi-layer anti-reflection coating. The coating suppresses flare and ghosting, repels water and oil, and resists fingerprints and dust, so the filter stays cleaner for longer and wipes down easily.

Optical Glass for High-Megapixel Sensors

Built with high-quality optical glass to preserve fine detail, the True Color Pro Nano CPL is engineered to keep up with today's highest-resolution full-frame and medium-format sensors without introducing softness or chromatic aberration.

A Size for Every Lens

Offered in thread sizes from 40.5mm through 105mm, the True Color Pro Nano CPL (Brass Frame) fits virtually every modern still and cine lens, from compact primes to large-diameter telephoto and wide-angle zooms.
