I know that there are various views on whether or not a clear or a UV filter is a good idea to put on a lens as protection. I am personally of the view that if you get a high quality filter, the lens will not be adversely affected by the filter. What are your thoughts? I am currently trying to decide between the B+W XS-PRO UV MRC-NANO (010M) and the B+W XS-PRO CLEAR MRC-NANO 007. What are your thoughts on "Clear" versus "UV" filters? On a personal pereference, what brand or particular filter would you use on your best lens to protect it? I am going back and forth between the B+W XS-PRO NANO filter and the Zeiss ZEISS T* UV Filter... Thanks!
