1 Increase Saturation: In landscape photography, by eliminating some stray light, the saturation can be increased, making the sky bluer, the white clouds more layered, and the picture more transparent. 2 Eliminate Reflections: CPL filters eliminate or weaken strong reflections on non metallic surfaces, and polarizers can eliminate reflections on glass surfaces and sunlight reflections on water surfaces, and take pictures of objects in the glass cabinet and under the water surface, making the image clearer. 3 CPL Polarizer: The surface of the filter is coated with an anti reflection coating, which can reduce the reflected light to less than 0.4% to eliminate the impact on imaging and reduce the occurrence of glaring. 4 Good Anti Oil Performance: The anti oil coating layer makes the lens surface slippy and not easy to be stained with stains, effectively protecting the lens, suitable for photographers to create with peace of mind in harsh environments. 5 CNC Precise Machining: This polarized filter lens is CNC precise molded, with non slip pattern, thin gold thread design, and the thin frame feels better.Item Type: Circular Polarizer
