Flange back adjustment may be required to correct a focal distance error generated due to attachment thickness of the installed lens.
Normally you do not have to make any adjustment, however, you can adjust focus of the installed lens with auto iris, when it provides images out of focus
at the maximum telephoto position. To adjust the flange back, follow the steps below.

Repeat steps 2 and 3 until
the image stays in-focus when
changing from a wide-angle
position to a telephoto
position. When the setting is
complete, tighten the flange
back lock screw.
Note: The flange back lock screw is tightened
completely when its tip hits the invisible
bottom, even though the screw head
may seem still up in the air. Do not screw
down any further beyond this normal
position as illustrated in Fig. 1.
