Quality with annoyances

What, however, I noticed already at an earlier B + W Slim filter for a wide-angle lens, looks even more clearly uncomfortable with this part. It is this unspeakable plastic cover. Since it does not seem to make it at B + W to apply a groove or notch on the filter holder to the original lens cap or another filter cap into one photo (other manufacturers do it even with filters for wide-angle), you have to try, draufzustülpen a With Cheap plastic cap who do not hold but in a different B + W filter bad at this. Leaving aside the filter on the lens, so you have to come to terms with the glass scuffed or scratched over time. EInfach annoying!
