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?
