Pentax 80 and Baader Zoom Mark IV (1 Viewer)


Well-known member
Has anyone tested this combination yet?

I currently have the Mark III version of this zoom which I had to modify in order to focus in my Pentax spotting scope. The issue was not enough backfocus meaning that I could not get focus at infinity.

The Mark IV has apparently been redesigned to address this issue with an attachment that provides an additional 4mm of backfocus.

I think this redesign will work but has anyone tried one yet?
