Formatt Hitech 95mm Firecrest Ultraslim Nonstackable Circular Polarizer Filter

OVERVIEW Minimize Reflections and Glare Reduces Haze and Blue Cast in Landscapes Enhances Color and Tonal Saturation 15-Layer Firecrest Multi-Coating Neutral Results Across All Spectrums Hydrophobic and Scratch-Resistant Schott Superwite Glass, Aluminum Ring Non-Stackable Filter Ring, 4.5mm-Thick Featuring a unique 15-layer multi-coated design, the Formatt-Hitech 95mm Firecrest UltraSlim Circular Polarizer Filter helps to reduce reflections and glare as well as increase the overall saturation of an image. This unique polarizer filter is characterized by the advanced Firecrest coating, which offers full attenuation of UV light for increased clarity and contrast, as well as a marked reduction in surface reflections and protection against scratching. A polarizing filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions. The UltraSlim aluminum alloy filter ring measures 4.5mm-thick and its slim design helps to minimize the likelihood of vignetting. This filter does not feature front threads in order to maintain the thinnest design possible for enhanced use on wide-angle lenses. Reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light. Lessens haze in distant landscapes and provides more saturated, vivid colors. Strongest effect when used at a 90° from the sun. The 15-layer Firecrest coating has been applied directly to the filter glass by way of a vacuum-formed, hard-coated, electrolytic process. The multi-coating is water- and scratch-resistance for greater overall durability. Firecrest coating attenuates UV contamination, as well as surface reflections, for increased contrast, clarity, and acuity. Schott Superwite glass is used in order to maintain clear image quality and high light transmission. The aluminum alloy UltraSlim filter ring measures 4.5mm-thick and does not feature front threads in order to maintain a slim profile that minimizes the likelihood of vignetting with wide-angle lenses.
