Circular polarizing filters are made for all cameras with beam splitters inside the light paths of their TTL exposure meter 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, use a higher efficiency than conventional polarizing foils, and so are cemented between high-grade plano-parallel optical glass, using a special cementing technique that resists delamination in humid climates. The resulting sandwich is then precision-polished again to realize highly accurate plano-parallel surfaces. Discriminating photographers regard the B+W Käsemann Polarizer as the very best polarizer for the market. They are well suited for applications that require the greatest 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 based on how a filter is positioned in relation on 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 of the incoming light for the meter and part for the viewfinder. The effect is that the lighting entering the meter is partially polarized with the beam-splitter. A linear polarizer placed about the lens of this kind of system will act as being a second polarizer and block light on the meter by method of a degree dependent around the angle relating to the prism as well as the polarizer for the lens. The actual result is incorrect exposure/aperture values in the meter. That is why you'll need a circular polarizer by using these cameras. The circular polarizer circumvents this issue by adding of an 1/4-wave retarder, or delay foil. This ensures the linearly polarized light is changed in to a rotation that appears unpolarized on the meter, leading to proper exposure/aperture readings.
MRC - A Particular Scratch-Resistant, Water and Dirt Repelling Coating
The left 1 / 2 of this filter has a
traditional coating. The right half
has MRC coating.
The lens components of high-quality lenses along with the plano surfaces of filters require an ideal shape and smoothness to achieve the best optical quality. Dirt, greasy fingerprints, water marks and scratches decrease the image contrast and the sharpness, which may bring about blooming at light sources and provide an effect similar 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. This implies what has reflection-reducing effect, which is thus also a 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 has a high effect within the medium wavelength range around yellow and yellow-green where the eye is most sensitive to light, while its effect is greatly reduced 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 is only able to be performed having a multilayer coating which requires a better effort and precision because unevenness and irregularities with the individual layers build up on each other and amplify one another. Schneider therefore runs on the plasma-assisted evaporation coating process by which inert gas ions accelerated in a electrical field compact the fabric deposited for the lens surface inside vacuum chamber.
For photographers, the main advantage of MRC coating, is it's power to combat flare and ghosting. An added benefit is that their filters remain clear of dirt longer, so that they actually do donrrrt you have being cleaned so often. When cleaning the filter does become necessary, it is really a lot better to wipe over dirt having a blower brush, as an effect of MRC's capability to repel dirt and moisture. This cuts down on the risk 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 includes a front accessory thread and is also made of brass. Compared towards the earlier standard mount, the F-Pro mount, introduced in 2001, is becoming thinner. Now it may be utilized 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 through the front, but props up filter glass in position from your back. When removing a filter or lens hood which has been screwed on too tight to the filter, the retaining ring is not vulnerable of loosening.
Circular polarizing filters are generated for all cameras with beam splitters within the light paths with their TTL exposure meter sufficient reason for autofocus lenses. Circular polarization has the identical 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 have 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 attain highly accurate plane-parallel surfaces. Subsequently they are edge-sealed to guard the foil against humidity. Discriminating photographers regard the B+W Käsemann-Type Polarizing Filter to get the very best of most polarizing filters. They are well suited for applications that need the greatest possible imaging quality, especially with high-speed telephoto lenses and apochromatic lenses.
