Everything that you have read or heard about this is true. German quality just like their cars.
Everything is built to a price and you get for what you pay.
Highly recommended. Buy Hoya if you don't want the best and are happy to throw away, lose or damage them.
High Quality Polarizing Filter July 30, 2008

Paired this polarizing filter to my Canon 17-40mm F/4L lens on a Rebel XT (1.6x Crop) and it works great. As you turn the filter the change in the image through the viewfinder is night and day. Creates a nice blue sky and gives more "pop" and contrast to clouds. Also eliminates reflections from plant leaves (you really have to see it for yourself!) to create a nicely saturated green only a filter of this type can produce. Must have for any outdoor photographer.
The "Kasemann" designation from my research stands for B+W's edge sealing of the glass. This is to prevent humidity and other types of weather from separating the foils inside. Over time regular polarizers can become hazy, etc. from that very problem. Just buy this one to keep for life instead of spending 50 dollars every few years. The filter frame is made out of brass, unlike other filters that are made of aluminum. This aids with smooth operation and eliminates binding.
I'm not entirely sure however if the wide angle of the 17-40mm needs a "slim" glass element (some say use of a regular polarizer with an ultra wide angle can cause an uneven polarization effect, however they are not clear if its on a crop body like the Rebel XT I'm using wit with). Some say a slim filter isn't needed, some do. I will have to do more outdoor shooting at the widest focal length to find out. Even so, B+W also produces a slim Kasemann version of this filter as well. From what i've seen though, vignetting is not a problem with the 17-40mm + this filter on a crop body such as the Rebel XT.
NOTE: I have also read that the way B+W produces the glass/foils will cause a "ripple" reflection effect in the glass when viewed at certain angles. This is true from what i've seen with my filter. looking at the filter from an angle and using a desk lamp, one can see the surface of the filter is not completely smooth. B+W has stated this does not affect the quality of the pictures in any way. Perhaps this may have led the other reviewer to believe that this filter scratches easy. The MRC they use is supposed to be very good.
In any case, a 77mm is the perfect size, as many Canon lenses use the 77mm thread such as the 70-200mm F/2.8L, the 24-105mm F/4L, and more. Plus you can always use "step up" rings with your smaller lenses.

I just received this polarizer in the mail today and I am blown away by its effectiveness. This is the first polarizer I've ever owned so I'm not an expert, but I think it is definately worth the price. I will upload some photos for demonstration.
The polarizer itself feels extremely solid and well-built, and looks beautiful for what it's worth. It is extremely easy to use, and fun to experiment with. The rotating ring spins very smoothly.
I highly recommend this product for any photographer, especially if you do landscape photography. I think it is a terrific investment.

If you have quality glass, like the Canon L series, then you need quality filters. the B+W are made from ground optical glass, not a piece of plain glass like as you see in the tiffen and hoyas filters (even the expensive ones are still cheap grade glass). Only B+W and Heliopan put the time and $$ into making filters that are designed to be used with your quality lenses and not distort and reduce the optical quality of them. I have 2 MRC, 1 Kaesemann, and 1 "plain" or Normal one, and I love them. I have a Heliopan as well, and I prefer the B+W a little bit more as its a brass ring and not aluminum and thus does not bind up as easy, and thats important when you want to change filters quickly! If you use a cheap filter on a pro grade lens, you are wasting your money, on the lens and the filter as the filter just hurt your image quality, and thus you lowered the quality of your lens! In filters, like lenses, you get what you pay for!!!
I shoot in all kinda of weather conditions, from sunny and warm, to windy and cold or snowy, and I have never had any major issues with any of my B+W filters acting up! I prefer the MRC or even the Kaesemann over the entry level one, but even their entry level one is ground glass, so you still get a great quality filter at that price point.
Best Circular Polarizer Money Can Buy September 19, 2007

My title says it all. If you spend L-series money on lenses, why not get the best filters?
B + W and Heliopan are made by Schneider Optics and are the best money can buy.
It's an expensive filter, but it will be the last 77mm circular polarizer I'll ever buy, unless this one is lost or damaged. It's nice to know that I cannot upgrade from this product.
