1Attach the lens to the camera.
At this stage, do not forget to connect the lens cable.
2Set the lens aperture to manual and open the aperture.
3Set the lighting in such a way that the appropriate video
output level is achieved at a distance of about 3 meters
away from the chart used for the flange back adjustment.
If the video level is too high, use the filters and shutter.
5Set the zoom ring to the telephoto position either
manually or electrically.
6Shoot the chart used for the flange back adjustment, and
turn the distance ring to adjust the focus.
8Repeat steps 5to 7until the focus is adjusted at both the
telephoto and wide-angle positions.
9Tighten the screw securing the F.f ring.
7Set the zoom ring to the wide-angle position, and turn the
F.f ring to adjust the focus.
Take care not to move the distance ring during this
process.
4Loosen the screw securing the F.f (flange focus) ring.
<Note>
On some lenses, this may be marked as F.b (flange back)
ring.

Adjusting the lens flange
If the subject is not focused properly in the telephoto and
wide-angle modes during zoom operations, adjust the flange
back (distance from the lens mounting surface to the image-
forming surface).
Once this adjustment is done, it need not be redone unless
the lens is replaced.
<Note>
For details on the adjustment method and lens positions, refer
also to the operating instructions that accompany the lens.
5Proceed with the flange back adjustment for the lens.
