Tokina 80-200 f/4.5 manual focus lens with a Minolta mount
This is a small (52 mm filter thread) push-pull zoom lens with excellent build quality and
decent image quality. It has a "macro" setting at 80mm that allows you to get fairly close.
I haven't been able to find out when this lens was made, but it was probably the late 70s to mid 80s.
