This lens "Carl Zeiss Jena 8cm f/2.0" has serious scratches/damages on the outer surface of the front glass. The owner want me t make it clean and clear again.
The only way to rescue the lens is to apply a polishing treatment. Following the traditional polishing procedure, the treatment won't alter the curvature of the target surface to keep the image performance the same as its original condition.
