There is very minor paint loss at the lens tip due to the attachment and removal of the hood, but otherwise, the lens exterior is in excellent condition with no signs of wear, scratches, or dents. Fully serviced in March 2024, the aperture ring has a satisfying click feel, and the helicoid moves smoothly without any stress. The rangefinder coupling is precise, and focusing is accurate. The glass has slight wiping marks on the middle element and coating degradation on the peripheral areas, but neither should affect the image quality. Test shooting results were positive.
