4 Push the cable into the cable clamp, and connect it to the LENS socket.

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.

Set 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.

Loosen the screw securing the F.f (flange focus) ring.

<Note>

On some lenses, this may be marked as F.b (flange back) ring.

Set the zoom ring to the telephoto position either manually or electrically.

Shoot the chart used for the flange back adjustment, and turn the distance ring to adjust the focus.

Set 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.

Repeat steps 5 to 7 until the focus is adjusted at both the telephoto and wide-angle positions.

Tighten the screw securing the F.f ring.
