Inneresting experiment this afternoon (plant shutdown gives me lots of time).
Mounted a Fujinon 135 5.6 W lens on a Deardorff lens board. Could not focus to infinity.
Must use a recessed board or not at all. Coverage looked like it would barely handle 5x7 but not 8x10.
Anyone else with this experience and how did you solve the focus issue?
