Ed -
I have had an opportunity to shoot some Polaroids, both at close
distances and infinity. The rangefinder does square pretty well
with the ground glass. I had to adjust the focusing scale. It is
interesting that the adjusted scale now reads infinity with the bed
racked all the way back. From what I have read, it should read a
bit beyond infinity cranked back all the way. Perhaps, this is not
always the case.
