The glass optics are also clean with no scratches, marks, fungus or dirt. It focuses smoothly and the aperture works properly with no problems. This is a sharp portrait lens great for everyday use! A beautiful lens to work on digital cameras with proper adapter! I have a money back return policy if not satisfied so buy with confidence.
