Here is a nice Promaster 72mm circular polarizer filter. It helps to reduce unwanted reflections and glare by filtering out light that has been polarized by reflecting from non-metallic surfaces. This helps to increase the saturation of elements like skies and foliage.
This filter is in mint condition with minimal wear. The glass is clean and scratch free with no haze, fungus, or other issues. The ring turns smoothly and the mount shows light wear.
It comes in the box with its soft bag.
