NiSi Polarizing Filter True Color CPL 82mm Purchased August 2023 I am selling this due to a review of my equipment configuration. It's in beautiful condition as I haven't used it much. * 【Eliminates color cast by completely renewing everything from the polarizing film to the coating】The newly developed polarizing film thoroughly pursues the uniformity of transmission and absorption across the entire visible light spectrum, and by minimizing the difference in transmittance (absorbance) of each wavelength, it has succeeded in achieving neutral color reproduction. * 【Unchanged resolution even when shooting with ultra-high-pixel cameras】Special polishing is applied to high-transmittance glass to achieve high planarity. It does not compromise its resolution even when shooting with ultra-high-pixel cameras that provide precise depiction. * 【Ultra-low reflection with NiSi's unique wide-band anti-reflection coating】NiSi's unique anti-reflection coating technology suppresses the surface reflection rate of the filter to 0.35% or less, improving the transmittance of light in a wide band. * 【Excellent water and oil repellent coating】Dust, fingerprints, water stains, etc. can be easily wiped off. * 【Improved light-shielding and airtightness by applying cinema sealing technology】By applying the sealing technology that has been used in cinema filters, the light-shielding and airtightness have been dramatically improved compared to the conventional black paint processing on the outer periphery of the glass. It prevents internal reflection due to light leakage and also prevents the entry of heat and moisture, extending the product life. ★Other Notes Although this product has been used infrequently, it is a used item.
