NiSi True Color Pro Nano CPL 86mm (Brass Frame)

Many circular polarisation filters introduce a warm or yellow cast that affects skin tones and skies. The True Color Pro Nano CPL uses NiSi's True Color polarising material for neutral and accurate colour rendering, making it ideal for landscape, travel, portrait and product photographers who rely on true-to-life colours straight from the camera.

Rotate the filter to reduce reflections from water, foliage, glass, painted surfaces and wet stone. Skies deepen, clouds gain contrast and detail visible beneath the surface returns to lakes, rivers and shop windows — without sacrificing sharpness or introducing colour shifts.

The ultra-thin brass frame is precision-milled and finished in a sleek, matt black colour. Brass threads more smoothly than aluminium and is far less prone to seizing on a lens's filter thread, even after years of use in the field, making installation and removal effortless. The knurled edges provide grip when the filter is cold, wet or when you're wearing gloves. Mounting and removing the CPL filter is quick and predictable, even in awkward shooting positions.

A small, knurled adjustment knob screws into the rotating ring for fast, precise control over the polarisation angle. When you prefer a streamlined profile or want to stack additional filters, the knob unscrews in seconds and can be stowed away. Both sides of the optical glass are treated with NiSi's Pro Nano multi-layer anti-reflection coating. The coating suppresses reflections and ghosting, repels water and oil, and resists fingerprints and dust, keeping the filter cleaner for longer and making it easy to wipe down.

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

The True Color Pro Nano CPL (brass frame) is available in thread sizes from 40.5mm up to and including 105mm and fits virtually every modern photo and cinema lens, from compact prime lenses to large-diameter telephoto and wide-angle zoom lenses.
