The B+W 77mm Kaesemann Circular Polarizer MRC Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

Kaesemann-type filters feature greater optical efficiency than regular polarizing foils and are more neutral in color. The polarizing foils are cemented between plano-parallel optical glass layers, which are then precision-polished to achieve the most accurate plano-parallel surface. This edge sealing protects the filter layers from humidity and are ideal for use with high-speed telephoto and apochromatic lenses.

The Multi-Resistant Coating (MRC) is both an anti-reflection coating as well as a protective surface. It helps to increase light transmission by reducing reflections, scattered light, and ghosting. Additionally, it offers greater protection to the filter substrate and stays cleaner for longer than uncoated filters.

B+W filters are constructed from high quality Schott glass for increased optical clarity and color fidelity. They feature a brass filter ring for durability as well as jamming prevention.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° from the sun.
Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
Kaesemann polarizing foils provide highly neutral coloring and higher image quality than conventional polarizing foils.
Multi-Resistant Coating offers both protection to the glass and helps to improve light transmission and image quality.
Constructed from high quality Schott glass for optical clarity.
Brass filter ring helps to prevent jamming and provides additional strength.

    77mm Kaesemann Circular Polarizer MRC Filter is rated 4.8 out of 5 by 412.
    Rated 3 out of 5 by from Polarizer filters often won't release Excellent glass and filtration (as it should be for a top-tier product and brand name B+W. But there's a big catch in terms of mounting threads... notorious for locking up once screwed on, especially when screwed into B+W's setup ring (anodized aluminum). Large front section of P-filter spins as is required for polarizing-angle use; behind that is a very tiny gripping area ring... that too-often refuses to unscrew. B+W claims they've never heard of the issue. Unscrewing it in the field under difficult circumstances is near impossible, even indoors. Do consider buying filter-wrenches. Oddly, B+W doesn't make any, nor provide them with a polarizer. In summary: great glass. Poor mount.

    Rated 5 out of 5 by from Quality to match lenses I've used B+W Circular Polarizers since investing in higher grade lenses. With quality lenses, I do not like to use filters any more than necessary - you pay more for the quality glass, why add another layer that could degrade the image? However, sometimes the situation calls for a circular polarizer. The filters from B+W have the high quality desired and are built to last. Recent trips to Yellowstone and Grand Teton National yielded great images taken with these polarizers. By the way, these and the B+W UV filters protected my front elements from the caustic gasses of the thermal features of Yellowstone). I had them in 52mm and 67mm sizes, then recently purchased two great lenses with 77mm filter sizes. I immediately ordered the third Kaesemann CP for these.

    Rated 5 out of 5 by from Replacement for Thin/Slim Version This purchase was actually a replacement for the thin/slim version that I keep on my walk-around camera at all times. Although I have other polarizers, the thin Kaeseman is the one that I use the most, and I rarely shoot without it. HOWEVER, failure of the slip-on cap to stay on is EXTREMELY irritating and has caused some minor scuffs on the surface of the polarizer. I liked its performance well enough to make this purchase (regular thickness), which I will reserve for use on my better cameras. It's a great filter, well worth the money...just don't buy the thin version if you must rely upon a lens cap for protection. It isn't worth the constant hassle of having to manually hold the cap on ALL the time.

    Rated 5 out of 5 by from A Great Step UP When I moved from a Canon crop sensors to a Canon full frame camera and Lens system, I knew one filter I had to to replace for my landscape work was a 77mm CP filter. I had a Hoya and while it was good on the crop, this B+W came up on sale and I knew I couldn't go wrong. The filter does not vignette at all at 24mm and color cast is non-existent on this filter. As for the few that complain, If you are careful enough, and know how tight it needs to be, you will never have a problem with it jamming and becoming stuck on your lens. I would recommend this filter without question.

    Rated 5 out of 5 by from Beautiful filter, BUY IT Great polarizer, even for the price. The quality is farsuperior to the cheaper equivalents, especially the Canonfilters, it really is worth the extra cash. I haven't usedthe Hoya, but I'm sure it will also be as nice. Don't try tosqueeze this on a wide angle lens though, you'll get a tonof fabulous vignetted filter edge in there. The filter is also very easy to clean. I've need to removewater spots or finger print smudges and been without lenscleaner, and with a nice cloth- no problem! Previous Equivalent Item Owned: Canon

    Rated 5 out of 5 by from Not bad for the price I originally wanted to get the Tiffen HT polarizer, but this one was cheaperyes really! Decided well why not. B+W of course manufactures some more expensive variations, but honestly it's not really worth it. If you are using a polarizer properly you're not going to have many issues with flare and ghosting because you're supposed to shoot 90 degrees from the sun or light source. Pretty solid build, but I wish the adjusting grooves were bigger to make adjusting the polarizer easier. There does seem to be some color shifting, but I actually enjoy the colors it produces so I'm not complaining. Pretty solid performance!

    Rated 5 out of 5 by from Great Filter This filter has a very nice finish and is easy to thread onto the lens and to remove by use of the knurled ring. I am getting an even tonal range (no noticeable fall-off) even at 17mm digital, and with no vignetting. I was also pleased to discover that I can attach/remove this filter (and other filters as well) with the lens hood in place on my 17-55 Nikkor. I have nothing negative to report about this lens very pleased.

    Rated 5 out of 5 by from good product Earlier reviewers liked the optical quality of this filter, and that was a major selling point for me. I tested it for effectiveness with polarized light and that certainly works. The tension between the front and rear rings of the lens is just right; not too difficult to turn and not so loose it drifts. As with any filter, be careful there's no grit involved in mounting the filter. The ring that screws into the lens is very thin, and if things get stuck there's not much for your fingers to grip, but it's a necessary evil to achieve a thin-profile filter. Maybe I should invest in a filter wrench...just in case. This filter was not an immediate must-have, so I waited until it was on sale and purchased it at a very attractive price.
