Got the 180/4.5 Xenar mounted on the new board Maddie printed for me, and decided to try it out yesterday. Shot an old brace and tenon cutter I had for chairmaking. Shot one at f/5.6, one at f/22. I'm not sure which (if either) I prefer on this.
f/5.6:

f/22:

Dunno. May need to revisit this later...
