K&F Concept 67mm Ultra-Low Reflectivity Circular Polarizer — 28-Layer Multi-Coating, 5.3mm Ultra-Slim HD Filter

Control reflections and deepen color with the K&F Concept 67mm Ultra-Low Reflectivity Circular Polarizer. Designed to suppress unwanted glare from non-metallic surfaces such as water and glass, it increases contrast and brings out finer details for more striking photos. Optical performance: reflectivity is held to just 0.1% to minimize lens reflections and haloing, producing a clearer image with improved contrast and detail. The filter removes 99.9% of polarized light while maintaining a high transmittance of 45%. Mechanical and optical build: the ultra-slim 5.3mm rim reduces the chance of vignetting on wide-angle lenses and still allows smooth rotation for precise polarization control, making it suitable for both wide-angle and telephoto use. The element is made from imported optical AGC glass and features double-sided 28-layer coatings that repel water, oil, dust and resist scratches. Housed in a durable, lightweight aluminum-magnesium alloy frame for long-lasting use. Compatibility: this Circular Polarizer is a 67mm screw-on filter — confirm your lens thread diameter (marked next to the “ø” symbol) before purchasing.
