This filter uses our standard B+W F-Pro filter mount, which has a front accessory thread and is made of brass.
MRC by B+W is not only an extraordinarily effective multiple layer coating, it is also harder than glass, so that it protects filters from scratches, and it is also water and dirt repellent, thus facilitating filter maintenance.
Manufactured from Water-White Schott Glass
Circular polarizing filters are made for all cameras with beam splitters in the light paths of their TTL exposure meter and with autofocus lenses. Circular polarization has the same pictorial effect as linear polarization, but allows for proper exposure metering and/or autofocus distance settings. The "high-end" polarizing foils of the Käsemann-type filters are neutral in color, they have a 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 are edge-sealed to protect the foil against humidity. Discriminating photographers regard the B+W Käsemann-Type Polarizing Filter to be the very best of all polarizing filters. They are well suited for applications that require the highest possible imaging quality, especially with high-speed telephoto lenses and apochromatic lenses.

I got the B+W 58mm Circular Polarizer MRC Filter a few months ago. I was so pleased with the results that when I got my Canon 17-55mm lens, I opted to go with a B+W again -- and B+W did not disappoint. This Käsemann filter works as claimed; it increases color saturation and reduces (and in some cases completely eliminates) reflection.
This filter is a marvel of engineering. The build quality is simply top-notch (the filter is Made in Germany).
This Filter vs A Non-Käsemann Filter ------------------------------------ I debated between this filter and the other B+W filte
I have used this lens filter for 3 weeks and feel the lens is solidly built and should last for many years. However, the polarization does not change dramatically on my Nikkor 85mm f1.4G lens. The richness of blue skies on my much cheaper Tiffen 77mm Circular Polarizer are much bluer and dramatic. This CP is not a good value considering the price paid vs. the results received during my use.
Update: (9/14/13) I downgraded this lens filter to 2 stars as it recently cracked from being bumped when attached to my Nikon 70-200MM f2.8 VRII lens being carried in my Lowepro camera bag. The only plus is that the lens was not damaged. I will not be replacing this expensive filter as it cannot withstand minor bumps. The filter glass was supposed to be specially treated against cracking from minor impacts. Inquiries to Schneider Electronics on a filter fix...
After reading a million reviews on a lot of filters, I ordered this B+W Kaesemann for a Canon 24mm wide angle lens. The lens itself makes crisp, clear, sharp pictures with awesome color and this lens just adds to it. The greens and blues are amazing, no need for post processing. I did find it to be quite dark indoors but that's fixable with camera settings. This lens came in a nice box, well packaged and is heavier than cheaper lenses because the glass is thicker and better quality. It is multi coated, a breeze to wipe off and everything it's cracked up to be. I also ordered the B+W UV filter and I'm very pleased with both. After using cheaper and mid level priced filters, I'm sold on the B+Ws. They are worth the extra cost and I'm already shopping for more!
