NiSi True Color Pro Nano CPL Brass Frame Filter

The NiSi True Color Pro Nano CPL Brass Frame Filter is a circular polarizing filter that reduces non-metallic reflections, deepens skies, and improves color saturation while maintaining natural color balance. Its True Color polarizing material helps avoid the warm or yellow cast common with many CPL filters.

Built for landscape, travel, portrait, product, and outdoor photographers, this circular polarizer helps control glare from water, glass, foliage, painted surfaces, and wet rocks. It is a strong choice for photographers who want to buy a CPL filter, upgrade to a brass frame polarizer, or use a True Color filter for accurate outdoor capture.

The filter combines high-resolution optical glass with NiSi Pro Nano multi-coating for sharp image detail and easier maintenance in the field. Its ultra-thin precision-milled brass frame, matte black finish, knurled grip sides, and removable adjustment knob support smooth handling, fast rotation, and a low-profile setup when needed.

Key Features

• True Color CPL Performance: Maintains neutral, accurate color while reducing glare and unwanted non-metallic reflections.
• Reflection Control: Helps tame glare from water, glass, foliage, painted surfaces, and wet rocks for cleaner images.
• Richer Saturation: Deepens skies, boosts foliage, and reduces atmospheric haze for more vibrant landscape results.
• Brass Frame Construction: Uses an ultra-thin precision-milled brass frame with a matte black finish for smooth installation.
• Knurled Grip Sides: Provides confident handling when mounting, removing, or rotating the filter in challenging conditions.
• Removable Adjustment Knob: Enables fast fingertip rotation and unscrews when a lower-profile setup is preferred.
• Pro Nano Multi-Coating: Double-sided anti-reflection nano coating resists water, oil, fingerprints, and dust for easier cleaning.
