Thanks for the edification. I have no knowledge of B+W filters. Rereading the original post I don't see any referal to the brand of filter. I have often wished to see a comparitive chart of the various filters. There have been some implied work (A. Adams - Schaffer Vol I e.g.) but where is a comprehensive list?
