Protective filters protect the front glass of your lens from small scratches and micro-damages that accumulate on its surface over time. Additionally, using them prevents direct contact of the front glass with dust, moisture, stains, and thus anything that could cause annoying blurring or spots touches the filter and not the lens.

The Hoya HD Protector Filter series offers chemically enhanced optical glass, four times stronger than ordinary glass filters, meaning it is more difficult to break. The 8 layers of anti-reflective coating provide unmatched protection against water and oils as well as resistance to scratches and stains.
