Focus point was "f/22 and be there" . The lens is on a helical and I have a marking for the focus point, as well as a little thing that attaches around the lens board and has the focus markings. But I hardly use it. Straight "up" is infinity, 45 degrees around the helical and stopped down to f/22 is "everything is in focus." If I have some really close-up stuff foreground I might go to 90 degrees. I had a loupe in my bag but didn't use it.
