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.

    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.

    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.

          Notwithstanding the persistent greasy smudge that took 20 minutes to clean, htis is an excellent polarizer. It actually brings out shadow detail as well as defining those bright areas that tend to get hazed and washed out. B+W filter exhibit a high level of quality, but this is the second one in less than 6 months that showed up dirty. (thus the 4 stars)

          Great quality as expected from B+W. Have not had a chance to do too much with it, but initial test shots appear great. Tested on Canon 10-22, Canon 24-105L, and 70-300L with step ring. No vignetting or other issues noted yet.

              Comments about B+W 77mm Kaesemann Circular Polarizer MRC Filter:

              Optically, this filter performs just the same of the top ranked Hoyas' and Nikon 2 - maybe just a tad slower though.

              Functionally, it's brass construction, crisp machining, and heft make it more durable and easier to use in the field. The brass construction is worth the extra money, as my other b+w filters have survived hits and drops with minimal deformation.

              I stopped using Hoya when I had one fall apart (retaining ring got loose), and on another a light ding also rendered the thread useless. Goodbye thin aluminium!

              The MRC coating seems to be tough to clean, until you realise you really have to put serious pressure on the glass surface. It doesn't like a delicate touch. It always feels like you're going to scratch the surface rather than clean it.

              The threads are nicely machined, but the paint on them is uneven - a little heavy in areas. At first they are a little gritty. It is advisable to thread them on and off another filter a dozen or so times before using in the field. Once the threads are worked in, they are fine.

              I would give this filter 5 stars, if only the threads didn't need to be worked in out of the box and it was perhaps a 1/3 of stop faster (like the competition).

                      The first time I purchased a 52mm B+W circular polarizer, i was really impressed by its build quality and performance. It functioned really smoothly and you could notice it work immediately. The build had some heft to it and the glass looked as though it good wistand some damage. I purchased the 77mm about a week later only because it was more convenient and i would no longer have to buy different size filters for lenses only step up rings. These filters are very well made and perform great. I highly recommend!

                        I use this on a Nikkor 24mm f/1.4G for mostly landscape shots.Very nice circular polarizer. I've had ones in the past that would be nearly impossible to remove without a filter wrench, so far this one has been pretty easy to take on and off. No issues with the rotating section becoming too loose or too tight. Haven't gotten it very dirty yet, but it has so far required very minimal effort to clean a stray fingerprint or two.I have no complaints about this item.

                          Purchased this polarizer in 77mm to use it with my Nikon 80-200 zoom. This is well made, mounts easily on a lens without binding.It is used for darkening skies, cutting down reflections of water and glass. With macro photography this filter allows me to enhance the subject.

                            I already have one of these filters in a different size. These filters are great. Durable and easy to clean. B+W=Quality

                            Little bit of a dust magnet.. But seems to be a good quality piece of glass for my expensive lenses. Wouldn't dream of using cheap glass!I would rate it a 5 if it wasn't for the dust....

                                does not vignette on cropped sensor UWA (canon 10-22mm).

                                its smoooth, haven't had any binding issues and i keep it on all day every day. I've only had to take it off if i'm shooting handheld at night.

                                no problem whatsoever with binding (so far).

                                the effect is very noticeable, must-have for day shooting.
