"Image Auto" Zoom lens. (Not Pentax A, K-A)
Pentax K-mount 80-200mm f/4.5 lens
Very good condition. Optically excellent. Zooming is not as firm as it used to be. It tends to slide on its own when fully vertical, maybe because the len is large.
Works great though.
Great for novice astrophotographers, coupled with tele-coverter it becomes a great telephoto lens for shooting the moon/eclispes.
