NiSi 72mm True Color Pro Nano CPL Circular Polarizing Filter (Brass Frame)

Overview

The NiSi 72mm True Color Pro Nano CPL Circular Polarizing Filter (Brass Frame) is designed to reduce reflections and glare from non-metallic surfaces while improving contrast and colour saturation. Ideal for landscape, travel, outdoor, and architectural photography, the filter helps reveal detail beneath water, reduce reflections in glass, and darken blue skies for cleaner, more balanced images.

Built around NiSi's True Color technology, this circular polarizer maintains a neutral colour balance without the warm colour cast often associated with traditional CPL filters. Combined with high-quality optical glass, Pro Nano multi-coating, and a precision-machined brass frame, it delivers reliable performance for modern high-resolution camera systems.

Core Features

• Reduces reflections and glare from water, glass, foliage, painted surfaces, and other non-metallic materials.
• Maintains neutral colour reproduction without introducing unwanted warm colour shifts.
• Enhances contrast and colour saturation for landscapes, skies, and outdoor scenes.
• High-quality optical glass preserves image sharpness and fine detail.
• Pro Nano multi-coating reduces flare and provides resistance to water, oil, and fingerprints.
• Precision-machined brass filter ring offers smooth installation and reduced thread binding.
• Knurled filter ring improves grip when mounting or removing the filter.
• Removable rotation knob provides precise adjustment of the polarization effect.

True Color Polarization

NiSi's True Color technology minimizes the warm or yellow colour shifts commonly found in traditional circular polarizers. This allows photographers to maintain accurate colour reproduction while benefiting from effective reflection control and improved scene contrast.

Brass Filter Ring

The ultra-thin brass frame is designed for smooth threading and long-term durability. Compared to aluminum filter rings, brass is less prone to binding, making installation and removal easier even after extended use.

Pro Nano Multi-Coating

Multi-layer coatings on both sides of the optical glass help suppress flare and ghosting while repelling water, oil, dust, and fingerprints. The result is improved image quality and easier cleaning in demanding shooting environments.
