Flange-back adjustment
If the pick-up surface is not correctly positioned with relation to the lens focal point, the picture will be out of
focus (in particular when using auto-iris power zoom lenses, sold separately). If that is the case, adjust the
flange-back position as described below.
1 Using a + screwdriver, loosen the flange-back lock screw (M2:+).
2 Set the zoom lens to the maximum telephoto position, set the focus using the focus ring on the lens.
3 Set the zoom lens to the maximum wide angle position, set the focus using the flange-back adjustment
lever.
4 Repeat steps 2 and 3, until the image stays in focus when changing from a telephoto shot to a wide angle
shot.
When the setting is complete, tighten the flange-back lock screw.
Note:
When flange-back lock screw is completely tighten it will protrude slightly as shown in the illustration (Fig. 1).
Do not tighten the screw further.
