I put UV filters in front of all my lens. One)to help remove the UV haze that shows up on some photos. Two) as protection for the front of the lens. If the filter get scratched, chipped, broken it is cheaper to replace it then buying a new lens.
A great value for a 72mm UV,CPL,FLD filter kit with wallet. UV filter
protects lens and CPL filter reduces glare and gives great blue skies in photo images.
