4.5 Back focus adjustment

To optimize picture sharpness in both bright and low-level

lighting, adjust the back focus. Use the camera's unique Lens

Wizard. This ensures that the object of interest always remains

in focus, even when focusing at the maximum lens iris opening

(for example, at night).

– When back focusing varifocal lenses, adjust to obtain a

sharp picture in both wide-angle and tele positions for

both far and near focus.

– When back focusing zoom lenses, ensure the object of

interest remains in focus throughout the entire zoom range

of the lens.

To adjust back focus:

1. Open the slide door panel at the side of the camera.

1. Unlock the back focus locking button.

2. Press and hold the center key for more than 1 second until

the Install menu appears.

3. Select Len Wizard and move cursor to the Set Back Focus

Now item.

4. Turn the back focus adjustment as required.
