This is a lens for Canon. The exterior has few scratches and is in beautiful condition. There is some dust inside the lens, but it is clean. *Regarding the reason for the issue: The focus is easier to achieve around 18-80mm during AF, but it is difficult to achieve focus around 135-200mm. (Focus could be achieved, and then shooting was possible) MF (Manual Focus) can be used normally. For safety, please consider this as a junk item. It is also recommended for those who want to use it for parts or can repair it themselves. If you have any questions, please feel free to comment. Accessories: Body Front cap Rear cap
