NiSi Filter Circular Polarizer True Color Pro Nano 77mm

NiSi Filter Circular Polarizer True Color Pro Nano 77mm – Provides true colors without the warming cast

The NiSi True Color Pro Nano Circular Polarizer (77mm) cuts reflections from non-metallic surfaces while preserving true color without the warming cast seen in many other CPLs. It uses an exclusive polarizer coating film to reduce unwanted reflections and deliver natural color rendering for both photography and filmmaking.

Key benefits

• Provides true color without the warming cast, keeping tones neutral and faithful to the scene.
• Eliminates reflections and reduces glare from non-metallic surfaces, improving contrast and clarity.
• Reduces haze in landscape photography, allowing finer detail and deeper skies.
• Nano coated for scratch resistance and added oil and water resistance, which helps maintain optical quality over time.
• Ultra slim frame design (4.9mm) reduces vignetting on wide-angle lenses and keeps the filter profile low.

Construction and technology

This CPL features an exclusive polarizer coating film combined with double-sided parallelization technology. As a result, each filter delivers ultra-high image definition and controlled polarization behavior. NiSi processes each filter with precision control to ensure consistent optical performance.

Additionally, the filter has a waterproof barrier on both sides, offering enhanced resistance to water, oils and stains. This coating allows easy and effective cleaning of dust, fingerprints and water marks.

NiSi True Color CPL also utilises Cine Sealed technology, which blackens the edge of the polarizer for added durability. This Cine Sealed treatment reduces the influence of temperature fluctuations and helps keep out condensation, protecting the internal optical surface.

The filter is built with an ultra slim "two colored" frame, designed to be both lightweight and less obtrusive on the lens.

Sizes and compatibility

While this listing refers to the 77mm version, the NiSi True Color Pro Nano Circular Polarizer is available in sizes from 40.5mm up to 105mm filter thread, covering a wide range of lenses.

How this filter performs in real use

Use this CPL to remove distracting reflections on water, glass and foliage, which improves color saturation and contrast. In landscape work, it helps reduce atmospheric haze and can make skies appear deeper without adding an artificial color cast. Because of its nano coating and waterproof barrier, you can clean the filter quickly on set or in the field, removing dust, fingerprints and water marks with minimal effort. Cine Sealed technology increases durability and reduces condensation risks during temperature changes.

FAQ

Question: Will this filter change the overall color balance of my images?

Answer: No. The NiSi True Color Pro Nano is designed to provide true color without the warming cast often introduced by other CPLs, so it maintains natural color balance while reducing reflections.

Question: How do I clean the filter if it gets fingerprints or water spots?

Answer: The filter’s nano coating and waterproof barrier on both sides resist oils and water, which allows for easy and effective cleaning of dust, fingerprints and water stains without aggressive scrubbing.

Question: Does the filter resist condensation and temperature changes?

Answer: Yes. Cine Sealed technology blackens the edge of the CPL to add durability, reduce the influence of temperature fluctuations and help keep condensation out of the filter.

Question: What sizes are available and what is the frame thickness?

Answer: The NiSi True Color Pro Nano CPL is available in sizes from 40.5mm to 105mm filter thread. The filter uses an ultra slim two-colored frame with a thickness of 4.9mm, which helps minimize vignetting on wide-angle lenses.
