Excerpt: The filter is exactly as advertised. It is not my first BW filter so I was not surprised. BW has always been a high quality product. I accidentally ordered the wrong one first and had to return the it. The service/return dept was great. The second one came even faster than the first one. Being used on at 21mm Leica.
Excerpt: Speedy service and the product was excellent however . . . the packaging was lacking--I felt my camera filter should have been more protected, plus the interior lens container was open when received --
