You've purchased good glass even if it's consumer glass. Why put a cheap filter on it? All filters cause additional flare that costs you contrast. The very best have the least flare. This B+W has been tested to show that it is almost flare free. Also cheap filters mount the glass stressed that bends with various temperatures and humidity. Aluminum rings oxidize with time. Brass does not, and you can easily remove this filter without a filter wrench. Schott Glass is the glass company owned by Schneider and is one of the most compelling reasons to buy a German made filter. Finally, these filters are batch dyed and have waterproof coatings that are very easy to clean and are very hard.
