I purchased this item used previously. It functions without any issues, and no noticeable dust or debris was observed on the lens. The condition is good, but it is still a used item, so please refrain from purchasing if you are overly concerned about its condition. Also, to prevent any product substitution, we will verify the serial number. Please feel free to ask any questions in the comments.
