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.

1Using a + screwdriver, loosen the FLANGE BACK LOCK screw (M2:+).

Set the zoom lens to the maximum telephoto position, set the focus using the focus ring on the lens.

2Set the zoom lens to the maximum wide angle position, set the focus using the FLANGE BACK ADJ. screw.

3Repeat 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.
