Polarizing Filter CPL K&F CONCEPT NANO-X Ultra-Low Reflection 43 mm (KF01.2471)

The Polarizing Filter CPL K&F CONCEPT NANO-X Ultra-Low Reflection 43 mm is a circular polarizer designed to reduce surface reflections, increase color saturation and improve image contrast for cameras with a 43 mm filter thread. The filter uses an ultra-low reflection multi-coating to maintain high light transmission while minimizing flare and ghosting, making it suitable for compact and mirrorless lenses. It is intended for landscape, outdoor and product photography where control over reflections and enhanced color depth are required.

Advantages

This CPL filter decreases unwanted reflections from non-metallic surfaces such as water and glass and helps deepen blue skies and boost overall color saturation without introducing significant light loss. The Nano-X ultra-low reflection coating reduces internal reflections and flare, preserving shadow detail and image clarity during backlit or high-contrast shooting. The circular design allows through-the-lens metering and autofocus compatibility on cameras that require a circular polarizer.

Suitable for

• Landscape photography to deepen skies and enhance foliage color
• Outdoor and travel photography where reflections from water or glass are present
• Product and still-life photography to control surface glare
• Compact and mirrorless camera systems with 43 mm filter thread

Key specifications

• Filter type: Circular polarizer (CPL)
• Thread size: 43 mm
• Coating: Ultra-low reflection multi-coating (Nano-X)
• Optical effect: Reduces reflections and enhances color saturation and contrast
• Compatibility: Designed for lenses with 43 mm front thread, suitable for compact and mirrorless lenses

How to use

Mount the filter onto the front of a lens with a 43 mm thread by screwing it gently until secure. Rotate the outer ring while viewing the scene through the viewfinder or on the camera’s LCD to adjust the degree of polarization; the effect is strongest at a 90-degree angle to the sun. Use exposure compensation or check the histogram if necessary, since the filter can slightly reduce incoming light. When shooting in low light or with very wide apertures, verify focus and exposure after attaching the filter.

Usage recommendations

Keep the filter clean and store it in a protective case when not in use to preserve the Nano-X coating performance. For maximum effect on skies, compose with the sun at a roughly 90-degree angle to the camera. Remove the filter when photographing metallic reflections or when a polarizing effect is not desired.
