PREPARATIONS FOR OPERATION

Back Focus Adjustment

It is only necessary to perform this when the lens is attached for the first time or when focusing is not correct in both the telephoto and wide-angle positions.

1. Set the IRIS mode switch to M (Manual).

2. Set the zoom mode to M (Manual).

3. Open the iris by turning the iris ring.

If the illumination is too strong, reduce it or move to a

darker place.

4. Turn the zoom lever until the lens is at the maximum tele-

photo position.

5. Bring the subject into focus.

6. Set the lens to maximum wide-angle.

White Balance Adjustment

Since the color of light (color temperature) varies depending on the light source, it is necessary to re-adjust the white balance when the main light source illuminating the subject changes.

•ERROR: LOW LIGHT (Insufficient illumination)

Displayed when the illumination is dim. Increase the illumi- nation and then re-adjust the white balance.

•ERROR: OVER LIGHT (Excessive illumination) Displayed when the light is excessively bright. Decrease the illumination and then re-adjust the white balance.

•It is easier to adjust back focus when the subject is more than 3 meters from the camera.

The optimal subject for this adjustment is a Siemens star chart.

7. Loosen the back focus ring retaining knob.

8. View the same subject and adjust the back focus ring for

the best possible focus.

9. Repeat steps 4. through 8. about three times for fine

adjustment until the subject remains in focus in both the

telephoto position and the wide-angle position.

10.Tighten the back focus ring retaining knob to secure the ring.

White Balance Adjustment

Two kinds of white balance adjustment results can be stored in memories AUTO A and AUTO B.

Error messages

If the adjustment ends abnormally, an error message, as described below, blinks for about 5 seconds.

•NG: OBJECT (Improper object)

Displayed when there is not enough white color on an object or the color temperature is not suitable.

Replace the color temperature conversion filter or use another white object and re-adjust the white balance.

•Do not adjust using any highly reflective objects, such as metal, etc., as this may result in improper white balance adjustment.

•The FAW (Full Auto White balance) function cannot pro- vide optimum white balance with a subject outside the FAW adjustment range, for example when it contains only a single color or not enough white color.

•The accuracy of the FAW (Full Auto White balance) is inferior to that of the Auto white balance.

•When the power is turned on with the FAW mode selected, it takes about 10 seconds for the FAW adjust- ment to be completed.

Do not shoot within this interval.

Full Auto White Balance (FAW)

The FAW function adjusts the white balance value automati- cally as the lighting condition changes.

This mode is convenient when you have no time to adjust the white balance or when the camera is moved frequently in and out of places under different lighting conditions.

„Setting procedure

The FAW function can be activated with the FAW item on the SWITCH MODE menu screen. The FAW function can be allocated to one of the white balance switching switches A, B, or PRESET.
