Ultra-low Reflection: The reflectivity of the ultra-low reflectance CPL filter is controlled to 0.1%, effectively reducing lens reflections and haloing, resulting in clearer images and increased contrast. *Please note that the exterior may be a mix of new and old, but the contents are the same. [Reflection Removal] This C-PL filter filters out 99.9% of polarized light and allows up to 45% high transmittance. Polarizing filters can enhance the colors of the sky and eliminate reflections on glass and water surfaces. PL filters remove surface reflections, allowing you to see the true colors of your images more vividly. Multi-layer Coating: The CPL filter is made of high-quality optical glass and features a double-sided multi-layer coating that effectively reduces reflected light. It features 28 layers of water-repellent, oil-repellent, and scratch-resistant coating, making it easy to wipe off water droplets and dirt. [Easy to attach and remove] To make it easier to attach and remove from the lens, the outer frame of the lens filter is knurled with a CNC trapezoidal pattern for anti-slip protection. [Note] To eliminate polarization, the polarizer must be angled, and only the scene and angle of use matter. The degree to which polarization can be eliminated varies depending on the angle and scene. The most effective angle is 30-40° from the plane, which eliminates reflections on the surface of water or leaves. *K&F CONCEPT is the world's No. 1 brand in terms of lens filter online sales volume among camera-accessory-focused brands.
