As always with B + W are accessed in the acquisition a little deeper into your wallet. But compared to (almost) all its competitors have been the best value for money here. Although the filters logically swallows something light intensity, I do not want to miss him. Not only in full sunlight and the desire to conjure away disturbing reflections of the filter on my lens. Even with extractor or other moderate lighting conditions you can "pimp" the motives something. Only indoor shots I make without filters. The quality of the thread and overall the excellent workmanship of the filter are raised, even after 2 years of use, beyond any doubt. The filter can be rotated easily, but is just as difficult, that it does not inadvertently corrupted by itself. Ideal for any dedicated (hobby) photographer who wants to rely on his equipment always.
