This beautiful German lens is a great fit for CCD imaging. The quality of Schneider optics is legendary. The 80mm to 240mm focal length is a good fit for a wide range of CCD imaging projects. f-4 means (of course) a short exposure time!
This lens is equipped with the standard (threaded) Pentax mount that is easy to fit to the standard T-2 thread: Pentax to T-2 adaptors are available though photography shops, etc. (or me, for $20, if you would like). It is in very good condition, no scratches on the optics.
I am asking $225; buyer pays actual shipping (your choice)
