Circular polarizing filters are created for all cameras with beam splitters within the light paths of the TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but permits proper exposure metering and/or autofocus distance settings.
Käsemann polarizing foils are neutral in color, have a higher efficiency than conventional polarizing foils, and are cemented between high-grade plano-parallel optical glass, employing a special cementing technique that resists delamination in humid climates. The resulting sandwich is then precision-polished again to accomplish highly accurate plano-parallel surfaces. Discriminating photographers regard the B+W Käsemann Polarizer as the top polarizer around the market. They are well suited to applications that need the best possible imaging quality, particularly with high-speed telephoto lenses and apochromatic lenses.
B+W Polarizers increase color saturation and reduce reflections. The filter factor varies as outlined by the way the filter is positioned in relation towards the sun. Exposure compensation is about two f-stops.
Why Use a Circular Polarizer?
Modern DSLR cameras have a very beam-splitting prism that sends part from the incoming light on the meter and part on the viewfinder. The effect is that the light entering the meter is partially polarized from the beam-splitter. A linear polarizer placed for the lens of a real system will act as being a second polarizer and block light towards the meter by way of a degree dependent on the angle involving the prism along with the polarizer around the lens. The result is incorrect exposure/aperture values through the meter. That is why you will need a circular polarizer with such cameras. The circular polarizer circumvents this challenge with the help of of the 1/4-wave retarder, or delay foil. This ensures how the linearly polarized light is changed right into a rotation that appears unpolarized to the meter, resulting in proper exposure/aperture readings.
B+W's Superior MRC Coating with Nano Technology

The nano coating is definitely an surface of protection which comes standard effortlessly XS-Pro Digital MRC filters. The nanotechnology based characteristic (lotus effect) produces an improved beading effect with water, making the cleaning on this filter even simpler and faster than previously before. MRC nano has an improved outer (8th) layer over regular MRC.
The lens components of high-quality lenses along with the plano surfaces of filters require a great shape and smoothness to realize the best optical quality. Dirt, greasy fingerprints, water marks and scratches decrease the image contrast along with the sharpness, which may bring about blooming at light sources and come with an effect comparable to a soft-focus lens. A clean front lens element and clean filter surfaces are therefore an absolute pre-requisite for demanding photographers.

The MRC coating is first and foremost a broadband anti-reflection coating. This implies the reason is reflection-reducing effect, that is thus another transmission-increasing effect, i.e. one which suppresses scattered light and ghost images and transmits more light, features a broadband action in the full spectrum. In contrast, the (almost always blue) single-layer coating only features a high effect inside the medium wavelength range around yellow and yellow-green in which the eye is most responsive to light, while its effect is greatly reduced toward the blue-violet and purple-red end regions from the visible spectrum. With the MRC coating, this blue, violet and red to deep-red light cannot produce any contrast reducing scattered light, spotty reflections or ghost images. A broadband effect can only be performed having a multilayer coating which needs a greater effort and precision because unevenness and irregularities from the individual layers build high on the other person and amplify one another. Schneider therefore utilizes 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.
For photographers, the main good thing about MRC coating, is it's capability to combat flare and ghosting. An added benefit is that their filters remain clear of dirt longer, so that they do not have to be cleaned so often. When washing the filter does become necessary, it is a lot much easier to wipe off of the dirt which has a blower brush, as a result of MRC's capability to repel dirt and moisture. And also this cuts down on the probability of micro-scratches which can occur during cleaning.
XS-Pro Digital Filter Mount
This filter uses our rotating XS-Pro Digital mount that is especially suited for DSLRs with wide angle and zoom lenses. It includes a front thread for additional accessories such as lens caps or hoods. All XS-Pro Digital mounts are made from brass and are matte black to prevent reflections.
Circular polarizing filters are made for all cameras with beam splitters in the light paths with their TTL exposure meter sufficient reason for autofocus lenses. Circular polarization has exactly the same pictorial effect as linear polarization, but permits proper exposure metering and/or autofocus distance settings. The "high-end" polarizing foils in the Käsemann-type filters are neutral in color, they use a higher efficiency than conventional polarizing foils and they also are cemented between high-grade plane-parallel optical glass. The resulting sandwich is then precision-polished again to achieve highly accurate plane-parallel surfaces. Subsequently these are edge-sealed to safeguard the foil against humidity. Discriminating photographers regard the B+W Käsemann-Type Polarizing Filter to get the most effective of all polarizing filters. They are very well fitted to applications that need the best possible imaging quality, particularly with high-speed telephoto lenses and apochromatic lenses.
