The workmanship is very good and otherwise I am completely at peace with the filter.
Actually have nothing else of B + W expected.
But a small problem there is, alas!
I use the filters with my Canon lenses, each having a diameter of 58mm. If I, however, want to equip one of my lenses with a lens hood, it is filter off, shutter and filter off turn again.
This is really annoying in the long run! It just does not fit, just under 1mm in diameter too much stuff!
Have therefore already the B + W Support contacted.
They told me that the outer diameter is not standardized and it sometimes can not fit therefore.
In my case this is true both for my 18-55mm with the EW-60C and the 55-250mm with the ET-60 to.
The support advised me I should try it nevertheless times with the F series, because other people already had the problem with the XS series and it should not occur there.
I'll now do and unfortunately send my good bit back.
EDIT
I now again the same filters bought and everything fits perfectly! There appears to be have been a faulty product, otherwise completely satisfied with everything!
