Digital Cameras Photo Reviews of B+W 77mm Kaesemann Circular Polarizer with Multi-Resistant CoatingCustomer Review: Pricey But Worth Every Penny Summary: 5 Stars
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 filter, the B+W 77mm Circular Polarizer MRC Filter. According to B+W (Schneider Optics), the Käsemann uses the same MRC (Multi-Resistant Coating) technology, but it's one-up on the non-Käsemann filter because it uses "high-end" polarizing foils. To quote Schneider Optics:
"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 plano-parallel optical glass."
Another advantage the Käsemann filter has over the non-Käsemann filter is that it is edge-sealed to protect the polarizing foil from humidity.
Since the Käsemann filter is only a tad more expensive (as of this writing), the choice between the Käsemann and the non-Käsemann filter was a no-brainer for me.
Tip

A common advice photographers give regarding filters is to pick a filter that fits the largest of your lenses so you can use the same filter for your smaller lenses as well (by using Step-Up Rings). Since step-up rings allow you to use this filter for your smaller lenses, this could be the only circular polarizer filter you need for *all* of your lenses with varying filter thread sizes (77mm, 72mm, 67mm, 62mm, 58mm, 55mm, 52mm, and 49mm).

If you have a high quality lens, you shouldn't scrimp on the filter because your pictures will be only as good as your lowest-quality lens component allow. This filter may be pricey, but it's well worth the money.
Description of B+W 77mm Kaesemann Circular Polarizer with Multi-Resistant CoatingCircular 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.
