The white balance adjustment is carried out. During the adjustment the legend “AUTO WHITE -OP-” appears in the viewfinder.

After a few seconds the adjustment is complete, and the legend in the viewfinder changes to “AUTO WHITE -OK-” plus a color temperature, as shown in the following figure.

-OK-￿ 3200K

The adjustment value is automatically saved in memory A or B as selected above.

To save the white balance adjustment for different lighting conditions, repeat steps 2 to 4 above. You can save two different values for the white balance, in memories A and B.

Note

When using a camera control unit or remote control unit, if the W/B BALANCE switch of the control unit is set to PRESET or MANUAL, it is not possible to carry out white balance adjustment on the camera.

To recall a white balance value from memory Before beginning shooting, set the W. BAL switch to the A or B position. This automatically sets the camera to the white balance adjustment saved in the corresponding memory.

If white balance adjustment cannot be completed automatically

The warning message “AUTO WHITE -NG-” appears in the viewfinder.

Make the necessary corrections, then carry out the process again.
