As a retired Professional Photogragher that used film, my changeover to DSLR required a different way of thinking. I just completed 4 night courses at the New England School of Photography in Boston, MA. I always put UV filters on as a protection to my lenses but when shooting with a digital camera they feel that they do not add to the pictures and recommend a solid glass filter. I use a Sony/ProMaster or Nikon Glass Filter as protection only. I had dropped my 70-200L lens while climbing to get a better shot and the sound of the lens hitting the ground was earth shattering. My filter saved all the glass but Canon had to make some slight adjustments.
