Kowa's 95mm Protective Filter shields the most important and sensitive area of your spotting scope: the objective lens. Sand and dust particles can cause scratches to the multi-coatings, and an accidental fall from the tripod can cause irreparable damage. This type of damage is expensive to replace and significantly decreases optical quality. The 95 mm Protective Filter drastically reduces the risk of objective lens damage, and prolongs the service life of your spotting scope.
