Adjusting the Lens Flange Back
If images are not clearly focused at both telephoto and wide-
angle positions during zoom operations, adjust the flange back
(distance from the lens mounting surface to the image formation
surface).
Once adjusted, the flange back does not need to be re-adjusted
as long as the same lens is mounted on the camera.
<Note>
Please also refer to the lens instruction manual for directions on
adjustment and locations of individual lens parts.
1
Mount the lens on the camera.
Make sure you connect the lens cable.
2
Set the lens iris to manual, and fully open the iris.
3
Place the flange back adjustment chart about 3 m from the
lens and adjust the lighting on the chart to obtain an
appropriate video output level.
If the video level is too high, use the filters or the shutter.

Loosen the F.f (Flange focus) ring clamping screw.
<Note>
F.b (Flange back) may be indicated on some lenses.

Aim the lens at the flange back adjustment chart and turn
the distance ring to bring the chart into focus.

ring to bring the chart into focus.
