Hoya 77mm PL-CIR Circular Polariser Filter cosmetically and optically this filter is in good clean condition, there is a minute mark on the filter but nothing that will affect the optical performance of the filter at all ( please see as I highlighted in the photo) Perpendicularly incident light waves tend to reduce clarity and saturation of certain colors, which increases haziness. The polarizing lens effectively absorbs these light waves, rendering outdoor scenes crisper with deeper color tones in subject matter such as blue skies, bodies of water and foliage.
