Adjusting the Black Balance
The first time you use the camera or if there is a noticeable change in the blacks of the video signal (such as
when ambient temperature changes considerably), it is recommended to have the camera adjust the black
balance.
You will need an external monitor connected to the camera, because the black balance can be adjusted only
by using buttons.
1 Turn off the camera.
• The camera does not have a power switch. To turn the camera
on or off, connect or disconnect the power cable.
• When using a compatible EF Cinema lens (
A
33) : Attach
the lens (
A
18).
When using other lenses : Remove the lens if one is attached
to the camera, and attach the body cap to the lens mount.
2 Turn on the camera.
3 Press the ABB button.
• Alternatively, you can use the [Camera Setup]
>
[ABB] setting.
4 Select [OK] and then press SET.
• The automatic black balance procedure will start. It will take approximately 40 seconds when the frame
rate is set to 23.98P.
5 When the message [Process completed successfully.] appears, press SET.
• If the sensor is not completely shielded from light, [ABB error] will appear on the screen. Press SET and
repeat the procedure from the beginning.
NOTES
• Adjusting the black balance is necessary in the following cases:
- After a long period of not using the camera.
- After sudden or extreme changes in ambient temperature.
- After resetting the camera's settings.
• During the adjustment of the black balance, you may notice some irregular displays appear on the screen.
This is not a malfunction.
• After adjusting the black balance with an EF Cinema lens attached to the camera, you will need to readjust
the aperture.
