Circular polarizing filters are designed for all cameras with beam splitters inside light paths of the TTL exposure meter along with autofocus lenses. Circular polarization has exactly the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings.
Käsemann polarizing foils are neutral in color, have a very higher efficiency than conventional polarizing foils, and are cemented between high-grade plano-parallel optical glass, utilizing a special cementing technique that resists delamination in humid climates. The resulting sandwich is then precision-polished again to achieve highly accurate plano-parallel surfaces. Discriminating photographers regard the B+W Käsemann Polarizer as the very best polarizer for the market. They are very well suited to applications which need the best possible imaging quality, especially with high-speed telephoto lenses and apochromatic lenses.
B+W Polarizers increase color saturation and lower reflections. The filter factor varies in accordance with how a filter is positioned in relation to the sun. Exposure compensation is approximately two f-stops.
Why Use a Circular Polarizer?
Modern DSLR cameras possess a beam-splitting prism that sends part from the incoming light on the meter and part for the viewfinder. The effect is the sunlight entering the meter is partially polarized through the beam-splitter. A linear polarizer placed around the lens of such a system will act being a second polarizer and block light for the meter by a degree dependent about the angle relating to the prism and the polarizer around the lens. The effect is incorrect exposure/aperture values through the meter. That's why you will need a circular polarizer with your cameras. The circular polarizer circumvents this issue with the addition of of a 1/4-wave retarder, or delay foil. This ensures that the linearly polarized light is changed into a rotation that appears unpolarized on the meter, resulting in proper exposure/aperture readings.
MRC - A Unique Scratch-Resistant, Water and Dirt Repelling Coating
The left half of this filter has a
traditional coating. The right half
has MRC coating.
The lens elements of high-quality lenses and also the plano surfaces of filters require an ideal shape and smoothness to accomplish the best optical quality. Dirt, greasy fingerprints, water marks and scratches lessen the image contrast along with the sharpness, which may bring about blooming at light sources and have 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.
MRC coating causes water
to bead up and slide right off.
The MRC coating is first and foremost a broadband anti-reflection coating. What this means is that its reflection-reducing effect, which can be thus another transmission-increasing effect, i.e. one which suppresses scattered light and ghost images and transmits more light, has a broadband action over the full spectrum. In contrast, the (almost always blue) single-layer coating only features a high effect in the medium wavelength range around yellow and yellow-green the location where the eye is most understanding of light, while its effect is cut down tremendously toward the blue-violet and purple-red end regions in 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 are only able to be performed having a multilayer coating which takes a better effort and precision because unevenness and irregularities in the individual layers build on one another and amplify one another. Schneider therefore uses a plasma-assisted evaporation coating process in which inert gas ions accelerated in an electrical field compact the material deposited around the lens surface within the vacuum chamber.
For photographers, the principle advantage of MRC coating, is it's ability to combat flare and ghosting. An added benefit is that their filters remain free from dirt longer, to ensure they actually do not have access to to get cleaned so often. When cleaning the filter does become necessary, it can be a lot much easier to wipe off of the dirt which has a blower brush, due to MRC's power to repel dirt and moisture. And also this cuts down on the chance of micro-scratches which can occur during cleaning.

F-Pro Brass Filter Mount
This filter runs on the rotating B+W F-Pro filter mount for added creative options. The mount has a front accessory thread and is also made of brass. Compared to the earlier standard mount, the F-Pro mount, introduced in 2001, is becoming thinner. Now it can provide with wide angle lenses, including most 24mm focal lengths on the full frame body, without vignetting. An additional advantage in the F-Pro mount is its modified retaining ring, that is no longer threaded in in the front, but props up filter glass set up in the back. When removing a filter or lens hood which has been screwed on too tight on the filter, the retaining ring isn't at an increased risk of loosening.
Circular polarizing filters are created for all cameras with beam splitters in the light paths with their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but enables proper exposure metering and/or autofocus distance settings. The "high-end" polarizing foils in the Käsemann-type filters are neutral in color, they possess a higher efficiency than conventional polarizing foils plus they are cemented between high-grade plane-parallel optical glass. The resulting sandwich is then precision-polished again to accomplish highly accurate plane-parallel surfaces. Subsequently they may be edge-sealed to protect the foil against humidity. Discriminating photographers regard the B+W Käsemann-Type Polarizing Filter to become the top coming from all polarizing filters. They are well fitted to applications that need the greatest possible imaging quality, especially with high-speed telephoto lenses and apochromatic lenses.

Why Use a Circular Polarizer?
Modern DSLR cameras have a very beam-splitting prism that sends part from the incoming light to the meter and part towards the viewfinder. The effect is that the lighting entering the meter is partially polarized by the beam-splitter. A linear polarizer placed for the lens of such a system will act being a second polarizer and block light towards the meter by a degree dependent on the angle involving the prism and the polarizer about the lens. The result is incorrect exposure/aperture values from the meter. This is exactly why you'll need a circular polarizer basic cameras. The circular polarizer circumvents this problem with the help of of the 1/4-wave retarder, or delay foil.
