Polarizers are essential filters for increasing the image quality of your outdoor photographs because they reduce atmospheric haze, increasing contrast between clouds and sky, and remove unwanted reflections from water, windshields, windows, and foliage. The Firecrest Circular polarizers are premium quality polarizers featuring our exclusive Firecrest anti-reflective multicoating providing your images will have the highest contrast and fidelity. Firecrest Circular Polarizers are housed in our precision milled SuperSlim or UltraSlim rotating polarizer rings.
