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 readjusted 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.

1Mount the lens on the camera.

Make sure you connect the lens cable.

2Set the lens iris to manual, and fully open the iris.

Approximately 3m

3Place 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.

4Loosen the F.f (Flange focus) ring clamping screw.

<Note>

F.b (Flange back) may be indicated on some lenses.

5Set the zoom ring to the telephoto position, either manually or by electric drive.

6Aim the lens at the flange back adjustment chart and turn the distance ring to bring the chart into focus.

7Set the zoom ring to the wide-angle position and turn the F.f ring to bring the chart into focus.

While focusing, take care not to move the distance ring.

8Repeat Steps 5 to 7 until the lens is in focus at both the telephoto and wide-angle positions.

9Firmly tighten the F.f ring clamping screw.
