In case you didn't already know Camera Electronic are the best place in town to get all your B+W filters. We always have in stock UV and Circular Polarizes from most sizes of lens along with a range of N.D filters of various sizes. We also carry other more specialized filters but if we don't have the exact filter that you are after in stock we can order it.
B+W filters have been the preferred high end filter for decades and when looking at the craftsmanship that goes into each one it's easy to see why. Filters are made to the highest of optical and mechanical standards by Schneider Optics Germany and unlike many filters which are simply rolled from glass blanks these filters are ground and polished in a similar way to the optics in your lens.
B+W was also the first manufacturer to employ MRC filter technology, this MRC coating allows the filters to repeal dust, dirt, water and scratches thus increasing the durability and life span of your investment.
