K&F Concept 40.5MM CPL Filter

The K&F Concept 40.5mm True Color CPL Filter removes reflections, enhances colors, and improves contrast using titanium coating technology for accurate color reproduction. Built with Japanese AGC optical glass and 28-layer nano-coating, it ensures UHD clarity, durability, and smooth rotation with its CNC-machined frame.

The K&F Concept 40.5mm True Color CPL Filter is crafted for photographers who demand both precision and color accuracy. Designed to eliminate reflections from water, glass, and other non-metallic surfaces, this CPL enhances skies, enriches colors, and improves overall contrast for vibrant outdoor imagery. Utilizing advanced titanium coating technology, it ensures true-to-life color reproduction without the partial-yellow shift common in standard polarizers.

Constructed with premium Japanese AGC optical glass, the filter is double-side polished to achieve ultra-high-definition clarity with no loss in image sharpness. Its 28-layer nano-coating provides waterproof, scratch-resistant, and oil-resistant performance while offering 45 transmittance and removing up to 99.10 of polarized light. The CNC trapezoidal aluminum frame enhances grip and allows smooth, precise rotation, making installation and removal effortless. Slim and lightweight, it also minimizes vignetting on wide-angle lenses.
