Eliminating Unwanted Reflections

The K&F Concept Nano-X CPL Circular Polarizing Filter for 77 mm lenses effectively removes reflections from non-metallic surfaces such as glass and water, enhancing contrast and color saturation. The precise adjustment knob allows full control over the polarization effect to optimize image quality.

Enhancing Nature Photography

Rotating the filter enables control over polarization intensity to:

• Enhance the blue intensity of skies
• Deepen green tones in foliage
• Reduce or eliminate light reflections

This results in photos with improved clarity and contrast.

Japanese Premium Quality

Constructed with optical glass from AGC, a renowned Japanese manufacturer with over 120 years of experience, the filter glass offers exceptional durability and excellent light transmission with very low reflectance (0.2%). Chemically reinforced, it is four times more durable than standard glass used in competing filters.

Durability and Protection

The 28-layer NANOTEC coating provides scratch resistance and hydrophobic properties, making water and grease stains easy to clean. This ensures true color reproduction and natural depth in your images.

Wide Compatibility

Compatible with most 77 mm thread lenses from major brands including Canon, Nikon, Sony, Fuji, Leica, Panasonic, and others, this filter integrates seamlessly into your photographic gear.

Ultraslim Design

The slim 5.5 mm thick aluminum frame minimizes vignetting, even with wide-angle lenses, ensuring uniform brightness across the frame.
