An interview from the 2015 PhotoPlus Expo in New York City with Niki Mustain of Schneider Optics. Schneider Optics has been producing the highest quality optics on the market for over 90 years, offering solutions for large-format photography, photo enlarging, motion picture projection, optical filtration, and industrial applications. In this interview Niki talks with us about their B+W Polarizer & ND Filters.
The B+W filter manufacturing company was founded in Berlin in 1947 by business partners Biermann and Weber. In 1985 the merger with the Jos. Schneider Optical Works in Bad Kreuznach expanded the B+W line of products with optical filters for science and technology. It also generated significant progress in multi-layer coating systems (MC). As a result, B+W became the first manufacturer of filters in the world to offer the innovative water- and dirt repelling MRC multi-layer coating process, which, in addition to its reflection-preventing qualities is also regarded as being especially scratch-resistant.
Thanks to it's adjustable density control, the B+W ND Vario filter can be adapted to your individual requirements. The XS-Pro mount offers an index setting, allowing the photographer to set the density between +1 and +5 stops. You may combine additional B+W ND filters of fixed value to achieve higher density choices. The ND Vario should be the outermost filter when combined with additional filters. The B+W XS-Pro ND Vario filters are all MRC nano coated, and are offered in sizes 52mm, 58mm, 62mm, 67mm, 72mm, 77mm, and 82mm. The XS-Pro Vario ND mount is an EW (extra-wide) design, and should avoid vignetting concerns with most 17mm lenses on a full frame body.
For B+W Polarizers, options include single coated (SC) and multi-resistant coating (MRC) in F-Pro mount Circular Polarizer, the High Transmission Circular (HTC) Kaesemann MRC polarizer in F-Pro, and (HTC) MRC Nano in XS-Pro mounts.
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.
