I am looking for your opinions on my lens / filter combinations. Because of circumstances I have three different 46mm UV filters: 1. B+W MRC F-Pro 2. Hoya HMC UV(C) 3. Kenco 'High Quality' Digital UV Filter They are to fit the following PL lenses: 14mm f2.5 Lumix 25mm f1.4 Leica 45mm f2.8 Leica I know which filter/lens combinations I have and the logic I used to determine them. But these may not be optimum. Which combinations would you use, and why?
