This high-quality polarizing filter is designed to optimize your image results with its neutral gray color and plane parallel polarizer material. Crafted from superior optical glass, this durable filter ensures excellent pictorial quality, making it a versatile tool for all your photography needs. The professional F-Pro mount Kasemanns feature MRC coatings, which significantly reduce reflections, glare, and lens flare, thereby improving image quality and contrast. Moreover, this effective filter comes with a front thread for additional accessories, enhancing its usability. The rounded, circular design of the filter ensures compatibility with a wide range of lenses, including wide-angle and fisheye lenses, without causing vignetting or other distortions. The B+W Kaesemann HTC (High Transmission Circular) Polarizer filters are renowned for their reflection reduction and improved color. These filters are particularly valuable for outdoor environments where lighting conditions can rapidly change. Traditional polarizing filters often result in a loss of up to 2.5 f/stops of light, affecting the desired depth of field or shutter speed. However, the B+W next-generation HTC filters, including this 37mm F-Pro Kaesemann High Transmission Circular Polarizer Filter, utilize a proprietary layer of specially selected, high-transmission polarizing foil. This innovative feature reduces light loss to just 1-1.5 stops, making this filter highly effective even in low light situations. In summary, this easy-to-use filter is a powerful tool for any photographer looking to improve image quality and work in a variety of lighting conditions. | B + W | | 37mm F-Pro Kaesemann High Transmission Circular Polarizer Filter, MRC Coating | Best Buy
