The filter frame shows little signs of use and looks clean. Although it's difficult to capture in photos, when held up to the light, both filters show what appears to be dirt? depending on the angle (the degree of dirtiness varies slightly). It's not too severe, but I'm not sure if it will affect actual image quality. It could not be removed by wiping with a lens cloth. How about using it for protecting old lenses or for modifications?
