I used this lens shortly after purchasing it, but it has been stored in a dry cabinet ever since. It has very little wear and is in excellent condition. There is no dust or debris inside the lens, and it is in very clean condition. A KENKO protective filter has been attached since the time of purchase. I am selling it because I am changing equipment. I am also selling a 2x teleconverter. Size...α E-mount Sony Model Name...FE 70-200mm F2.8 GM OSS
