B & W typical, very good quality

I ahbe my filter for the EF 70-300 L IS USM (filter diameter 67mm B + W UV HAZE filter (67mm, MRC Nano XS-PRO digital)) bought, as these expensive lenses in my view, the protection of the front lens is indispensable. I ahbe all my lenses with (UV) filters care provided from B & W and have not yet been disappointed. Both the EF 24-105 L IS USM and the 100mm Macro L IS USM make it visually outstanding job. The surface on the metal edge of the UV HAZE MRC nanofilter feels very comfortable and high quality. Maybe it's IEnbildung that he feels better than the others.
Even a small digression:
also the polarizing filter from B & W (Käsemann) is excellent! Not screw respect to fixed, because otherwise he firmly turns more and more during the adjustment! Since then helps only the rubber strap for cans open (despite graphite)! B + W Circular Polarizer Slim Käsemann AUCM SL 77 E
Important for me:
The cap of Canon still holds absolute since not all filters so, especially not at SLIM format filters.
