B + W - 39mm Basic 486M MRC UV/IR Cut Filter

Under the umbrella of B+W's esteemed product line, the 39mm Basic 486M MRC UV/IR Cut Filter stands as a high-quality, durable, and reliable tool for photographers. This versatile filter is specifically engineered to combat unwanted UV and infrared components that can compromise the clarity and color accuracy of your images. Unlike conventional filters, the B+W 486 UV-/IR-Cut filter employs a unique interference method, utilizing a series of wafer-thin, partially reflecting layers with a meticulously calculated thickness. This innovative design ensures a sharp cut-off absorption, effectively preventing color casts and blurring that can occur in digital cameras where the IR barrier in front of the image sensor displays some residual transmittance.The B+W 486 UV-/IR-Cut filter is clear and colorless, ensuring no additional exposure is required during use. Its design allows it to be left on the lens permanently, serving as an effective protection filter. Further enhancing its performance, the filter features a Multi-Resistant Coating (MRC), which reduces reflections and improves light transmission for superior image quality.Ideal for lenses with an aperture angle up to 60 degrees, the B+W 486 UV-/IR-Cut filter operates on the principle of an interference filter, which results in an aperture angle-dependent color influence. As the angle of the incident light increases, it drifts towards blue, meaning that for wide-angle lenses with an aperture angle larger than 60 degrees, the color reproduction at the edge of the image tends to lean towards bluish. In summary, the B+W 39mm Basic 486M MRC UV/IR Cut Filter is an essential tool for photographers seeking to enhance their image quality by effectively filtering out ultraviolet and infrared light.
