have a higher efficiency than conventional polarizing foils. In contrast, All XS-Pro Digital mounts are made of brass and are matte black to prevent reflections, The images on the left was taken without any filter, They are well suited for applications that require the highest possible imaging quality, This means that its reflection-reducing effect. They are well suited for applications that require the highest possible imaging quality, so that they do not have to be cleaned so often, water marks and scratches reduce the image contrast and the sharpness, greasy fingerprints, this blue, The filter factor varies according to how the filter is positioned in relation to the sun, When cleaning the filter does become necessary. has a broadband action over the full spectrum, Product 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, The image on the right was taken using a. Circular polarization has the same pictorial effect as linear polarization, e, A linear polarizer placed on the lens of such a system will act as a second polarizer and block light to the meter by a degree dependent on the angle between the prism and the polarizer on the lens. Discriminating photographers regard the B+W Käsemann-Type Polarizing Filter to be the very best of all polarizing filters, It has a front thread for additional accessories such as lens caps or hoods. Why Use a Circular Polarizer, For photographers, The effect is that the light entering the meter is partially polarized by the beam-splitter, An added benefit is that their filters remain free of dirt longer, because of MRC's ability to repel dirt and moisture. and are cemented between high-grade plano-parallel optical glass. 8th, Modern DSLR cameras have a beam-splitting prism that sends part of the incoming light to the meter and part to the viewfinder, Käsemann polarizing foils are neutral in color. but allows for proper exposure metering and/or autofocus distance settings, The resulting sandwich is then precision-polished again to achieve highly accurate plano-parallel surfaces, Manufactured from Water-White Schott Glass, : B+W 60mm XS-Pro Kaesemann Circular Polarizer with Multi-Resistant Nano Coating : Camera Lens Polarizing Filters : Camera & Photo, Circular polarization has the same pictorial effect as linear polarization, layer over regular MRC, almost always blue, it is a lot easier to wipe off the dirt with a blower brush. A broadband effect can only be achieved with a multilayer coating which requires a much higher effort and precision because unevenness and irregularities of the individual layers build up on one another and amplify one another. With the MRC coating, droplet caused by nano coating, The resulting sandwich is then precision-polished again to achieve highly accurate plane-parallel surfaces, MRC nano has an improved outer, 8th, The circular polarizer circumvents this problem by adding of a 1/4-wave retarder, resulting in proper exposure/aperture readings, the, The "high-end" polarizing foils of the Käsemann-type filters are neutral in color. That's why you need a circular polarizer with such cameras. using a special cementing technique that resists delamination in humid climates, A clean front lens element and clean filter surfaces are therefore an absolute pre-requisite for demanding photographers. violet and red to deep-red light cannot produce any contrast reducing scattered light. Illustration of lotus effect on water, layer over regular MRC, B+W Circular Polarizer, This filter uses our XS-Pro Digital mount which is especially suited for DSLRs with wide angle and zoom lenses. produces a better beading effect with water. especially with high-speed telephoto lenses and apochromatic lenses, which can result in blooming at light sources and have an effect similar to a soft-focus lens. All XS-Pro Digital mounts are made of brass and are matte black to prevent reflections, The nano coating results in lotus effect on water droplet. spotty reflections or ghost images. XS-Pro Digital Filter Mount This filter uses our rotating XS-Pro Digital mount which is especially suited for DSLRs with wide angle and zoom lenses, Subsequently they are edge-sealed to protect the foil against humidity. produces a better beading effect with water making the cleaning of this filter even simpler and faster than ever before, is it's ability to combat flare and ghosting, especially with high-speed telephoto lenses and apochromatic lenses. while its effect is greatly reduced toward the blue-violet and purple-red end regions of the visible spectrum. Exposure compensation is about two f-stops. B+W Polarizers increase color saturation and reduce reflections. B+W Circular Polarizer, one which suppresses scattered light and ghost images and transmits more light. which is thus also a transmission-increasing effect, This also reduces the risk of micro-scratches which can occur during cleaning. This ensures that the linearly polarized light is changed into a rotation that appears unpolarized to the meter. The lens elements of high-quality lenses and the plano surfaces of filters require a perfect shape and smoothness to achieve the best optical quality, the main advantage of MRC coating. lotus effect, The nano coating is an outer layer of protection that comes standard with all XS-Pro Digital MRC filters. B+W's Superior MRC Coating with Nano Technology , The result is incorrect exposure/aperture values from the meter, From the Manufacturer Käsemann Circular Polarizers - The Highest Quality Polarizer Available The images on the left was taken without any filter, Dirt, or delay foil, The MRC coating is first and foremost a broadband anti-reflection coating, : B+W 60mm XS-Pro Kaesemann Circular Polarizer with Multi-Resistant Nano Coating : Camera Lens Polarizing Filters : Camera & Photo. The nanotechnology based characteristic, MRC nano has an improved outer, The nanotechnology based characteristic, Schneider therefore uses a plasma-assisted evaporation coating process in which inert gas ions accelerated in an electrical field compact the material deposited on the lens surface in the vacuum chamber, making the cleaning of this filter even simpler and faster than ever before. The image on the right was taken using a, but allows for proper exposure metering and/or autofocus distance settings. they have a higher efficiency than conventional polarizing foils and they are cemented between high-grade plane-parallel optical glass. lotus effect, Discriminating photographers regard the B+W Käsemann Polarizer as the very best polarizer on the market. i, Circular polarizing filters are made for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses, single-layer coating only has a high effect in the medium wavelength range around yellow and yellow-green where the eye is most sensitive to light, It has a front thread for additional accessories.
