Schneider Optics B+W 46mm Clear with Multi-Resistant Coating (007M)

Description

Circular polarizing filters are made for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings. The "high-end"polarizing foils of the Käsemann-type filters are neutral in color, they have a higher efficiency than conventional polarizing foils and they are cemented between high-grade plano-parallel optical glass. The resulting sandwich is then precision-polished again to achieve highly accurate plano-parallel surfaces. Subsequently they are edge-sealed to protect the foil against humidity. Discriminating photographers regard the B+W Käsemann-Type Polarizing Filter to be the very best of all polarizing filters. They are well suited for applications that require the highest possible imaging quality, especially with high-speed telephoto lenses and apochromatic lenses. Review: A well built filter - This is a good example of what a UV filter should be. Made from quality materials with a bright and color cast free coating. The coating provides an easy to clean surface incase dirt or finger prints accumulate on the surface. Review: Authenticity is uncertain, but the filter seems to be fine as protection for lens. - Item received in short time. The filter seems fine. However, the B+W font on the rim does not seem to be the same as my other B+W filter. I can't find this particular type among official B+W filter site. Hence, the authenticity of the filter can't be verified.
