Hi guys wondering does any of your B+W brass filters have tiny specks of "pimples" on the surface of the filter after a period of use? Is it kind od a oxidation process? Thanks!

on the glass? yeah I remember seeing it on the B+W UV-MRC filter I usually have on my workhorse zoom (for memory a little like an orange peel effect?) - you really need good eyes and get the right angle to see it. The shop (which is the distributor down here) said it's normal and I've never noticed any negative affect image quality so I never worried about it.
