Circular Polarizing Filter NiSi True Color CPL Pro Nano 72mm - camera lens filter

NiSi True Color CPL Pro Nano 72mm is a circular polarizing filter designed to attach to lenses with a 72mm thread to reduce unwanted reflections from non-metallic surfaces, increase color saturation and improve sky contrast. The filter uses polarizing optics to control glare and enhance scene clarity while maintaining neutral color balance. A hydrophobic and oleophobic nano coating repels water and oil, helping to keep the optical surface cleaner during outdoor shoots.

Advantages

The NiSi True Color CPL Pro Nano 72mm provides effective polarization with minimal color cast, preserving accurate tones while increasing saturation and contrast. The Pro Nano multi-coating reduces reflections on the filter surface and improves light transmission for sharper images. Its slim design minimizes vignetting on wide-angle lenses while the durable metal frame provides reliable mounting and secure fit. The hydrophobic/oleophobic surface treatment facilitates cleaning and resists fingerprints, moisture and dust.

Suitable for

• Landscape photography to deepen skies and reduce reflections on foliage and water
• Outdoor and travel photography where glare control improves image clarity
• Architectural and product photography to minimize reflections on glass and polished surfaces
• General purpose use when shooting through windows or near water

Key specifications

• Filter type: circular polarizer (CPL)
• Filter thread size: 72 mm
• Optical coating: Pro Nano multi-coating with hydrophobic and oleophobic layers
• Frame material: metal slim profile to reduce vignetting
• Optical effect: reduces reflections, increases color saturation and sky contrast

How to use

Mount the NiSi True Color CPL Pro Nano 72mm onto a lens with a matching 72mm thread. Rotate the outer ring while observing the viewfinder or live view until the desired reduction in reflections and increase in contrast is achieved. For scenes with strong reflections from water or glass, rotate slowly to find the optimal polarization angle. Clean the filter surface using a microfiber cloth and, if necessary, a small amount of lens-safe cleaning solution; avoid abrasive materials to preserve the nano coating.

Usage recommendations

Use the filter primarily when shooting at angles where light is reflected from non-metallic surfaces; it is less effective when shooting directly into the sun. When using wide-angle lenses, check for vignetting and, if present, consider a slim filter profile or step-up ring. Store the filter in its protective case when not in use to protect the coated surface and threads.
