Circular polarizing filters are generated for all cameras with beam splitters within the light paths of the 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.
Käsemann polarizing foils are neutral in color, use a 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 attain highly accurate plano-parallel surfaces. Discriminating photographers regard the B+W Käsemann Polarizer as the most effective polarizer about the market. They are very suited for applications that need the greatest possible imaging quality, especially with high-speed telephoto lenses and apochromatic lenses.
B+W Polarizers increase color saturation and reduce reflections. The filter factor varies in accordance with what sort of filter is positioned in relation for the sun. Exposure compensation is about two f-stops.
Why Use a Circular Polarizer?
Modern DSLR cameras have a beam-splitting prism that sends part in the incoming light on the meter and part for the viewfinder. The effect is the very fact that the sunlight entering the meter is partially polarized from the beam-splitter. A linear polarizer placed on the lens of this kind of system will act being a second polarizer and block light for the meter with a degree dependent around the angle between the prism and the polarizer about the lens. The actual result is incorrect exposure/aperture values in the meter. This is exactly why you need a circular polarizer basic cameras. The circular polarizer circumvents this issue with the help of of a 1/4-wave retarder, or delay foil. This ensures that the linearly polarized light is changed right into a rotation that appears unpolarized towards the meter, leading to proper exposure/aperture readings.
MRC - a Special 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 components of high-quality lenses and also the plano surfaces of filters require a great shape and smoothness to realize the best optical quality. Dirt, greasy fingerprints, water marks and scratches lessen the image contrast as well as the sharpness, which can bring about blooming at light sources and come with an effect just like 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 it is reflection-reducing effect, that is thus additionally a transmission-increasing effect, i.e. one which suppresses scattered light and ghost images and transmits more light, has a broadband action within 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 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 takes a much higher effort and precision because unevenness and irregularities with the individual layers build through to one another and amplify one another. Schneider therefore utilizes a plasma-assisted evaporation coating process in which inert gas ions accelerated in a electrical field compact the fabric deposited for the lens surface within the vacuum chamber.
For photographers, the principle benefit of MRC coating, is it's power to combat flare and ghosting. An added benefit is always that their filters remain without any dirt longer, to ensure they actually do donrrrt you have to become cleaned so often. When washing the filter does become necessary, it is often a lot easier to wipe off the dirt which has a blower brush, due to MRC's power to repel dirt and moisture. And also this decreases the probability of micro-scratches which could occur during cleaning.

F-Pro Brass Filter Mount
This filter uses a rotating B+W F-Pro filter mount for added creative options. The mount includes a front accessory thread and is also made from brass. Compared towards the earlier standard mount, the F-Pro mount, introduced in 2001, is becoming thinner. Now it could be used with wide angle lenses, including most 24mm focal lengths on the full frame body, without vignetting. An additional of the F-Pro mount is its modified retaining ring, that is will no longer threaded in from your front, but supports the filter glass set up through the back. When removing a filter or lens hood which includes been screwed on too tight towards the filter, the retaining ring isn't at risk of loosening.
Circular polarizing filters are made for all cameras with beam splitters inside light paths of these 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 with the Käsemann-type filters are neutral in color, they have a very higher efficiency than conventional polarizing foils and they 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 they may be edge-sealed to safeguard the foil against humidity. Discriminating photographers regard the B+W Käsemann-Type Polarizing Filter to be the top coming from all polarizing filters. They are very fitted to applications that require the greatest possible imaging quality, especially with high-speed telephoto lenses and apochromatic lenses.
