I rate it cosmetically a (9). The lens extends and retracts properly and the aperture ring is smooth, but the focus ring is a bit stiff. The aperture functions properly, and the glass is clean and clear with no haze, marks, or fungus. There are a few faint specks of dust inside, but they do not affect image quality. This lens is for Leica screw mount\/thread mount (LTM) and other E39 bodies. It includes front \u0026amp; rear caps.\u003c\/p\u003e\n\u003cdiv class=\"flex flex-col text-sm pb-25\"\u003e\n\u003carticle class=\"text-token-text-primary w-full focus:outline-none
