Circular Polarizing Filter K&F Concept Nano X CPL 72mm for lenses with 72 mm thread

Circular Polarizing Filter K&F Concept Nano X CPL 72mm for lenses with 72 mm thread reduces reflections from non-metallic surfaces, increases color saturation and contrast, and helps control glare in bright outdoor conditions. The filter mounts on lenses with a 72 mm filter thread and is designed for photographers who need improved sky rendering, deeper foliage tones and clearer water surfaces without digital processing. The Nano X coating helps repel water and oil and facilitates cleaning while maintaining image sharpness.

Advantages

The circular polarizer selectively reduces polarized light, enabling more intense blue skies, richer greens and better separation of distant details. The slim, rotatable mount allows precise adjustment of the polarization effect without vignetting on most lenses with a 72 mm thread. Multi-coating minimizes internal reflections and ghosting, preserves contrast and provides easier maintenance due to the hydrophobic and oleophobic surface.

Suitable for

• Landscape photography to enhance skies and foliage
• Architectural and exterior shots to reduce window and facade reflections
• Outdoor portrait and travel photography in bright conditions
• Scenes with water or wet surfaces to control surface reflections

Key specifications

• Filter type: Circular polarizer (CPL)
• Thread size: 72 mm
• Mount: Rotatable slim frame to reduce vignetting
• Optical glass: Multi-coated glass with hydrophobic/oleophobic Nano X surface
• Effect: Reduces polarized glare, increases saturation and contrast

How to use

Thread the filter onto a lens with a 72 mm filter thread and rotate the outer ring while viewing through the viewfinder or live view until the desired reduction of reflections and increase in color saturation is achieved. Because the CPL reduces light transmission, compensate exposure as needed—typically 1–2 stops depending on the angle of polarization. Keep the Nano X coated surface clean and handle the filter by the edges to avoid fingerprints.

Usage recommendations

Use the filter at 90 degrees to the sun for the strongest sky darkening effect and adjust rotation for partial polarization effects. Avoid using the CPL at very wide angles on some wide-angle lenses where uneven polarization may appear. Store the filter in its protective case when not in use to preserve the coating and optical performance.
