Works when attached to a camera. The lens has a lot of light mold, some slight dirt, and dust. I didn't feel much impact when taking pictures. The body seems clean. When manually turning the focus ring, there is a slight resistance around the 0.85m mark, and a little unevenness in rotation. AF operation is smooth and there are no problems. This is a junk item due to the issues described. Shipped via Takkyubin (Express Home Delivery).
