Personally, I have proposed to use filters in recent years, provided that the quality filter. The filters that I use does not seem to affect the optical problems or Flare. I and my friends spent a few weeks in order to experiment with the lens, wondering if I could actually measure the resolution of the lens when not in and have filters. I just bought a used lens comes with a filter made of plastic, so I decided to run separate trials for a project. Experiment 1: Do not use filters and filter BW substance use high test 2: Do not use filters and filter using a cheap plastic. the result of the study is quite interesting.
