Operation confirmed. There may be some minor dust, but there doesn't appear to be any noticeable dust or debris. However, when a strong light is shone on it and you look closely, you can see what appears to be a small amount of point-like mold. When used, it doesn't seem to affect the image quality. Please understand that there may be some signs of use, minor dust, and debris. Please purchase with the understanding that this is a used item and that the inspection was done by an amateur.
