Hello gang... I am a long-time UH stalker that finally would like a group response. We were burned out in the northern California Camp fire, and I am slowly rebuilding my gear, hence the excuse for 'replacing' my camera :>). For years I used a UV filter to protect my lenses from mechanical damage until a pro whom I respect said 'oh no.. that degrades your images'. But now with two shiny new lenses, how much really do I need to worry about that ? Thanks for your responses in advance !!
