@
NOTE
t Even if color temperature is set manually, the color temperature adjusted automatically is recorded to the setting of the <WHITE BAL> switch at
that time if white balance is automatically adjusted. The value of the color temperature also changed when the position of the <CC FILTER> dial is
switched.

Black balance adjustment

Black balance must be adjusted in the following instances:
f When the camera is used for the first time
f When used after a long period of time without use
f When the ambient temperature has changed considerably
f When super gain is set with the USER button
f When the [CAMERA] menu → [USER SW] → [USER1] to [USER5] → [DS.GAIN] is assigned
f When the digital super gain assignment is changed in the [CAMERA] menu → [USER SW GAIN] → [DS.GAIN]
f When toggling items in the [SYSTEM] menu → [REC FORMAT].
To shoot optimum video, we recommend adjusting the black balance immediately before shooting.
Before adjusting the black balance, prepare the conditions for adjusting the white balance.

NOTE
t Make sure that the lens connector is connected and that the lens aperture is in the close mode.
t During black balance adjustment, the aperture is set to automatically shut out light.
t During recording, black balance cannot be adjusted.
t Video is not recorded to the memory card even if the <REC> button is pressed while executing the automatic black balance.
t The gain switching circuit is automatically switched during black balance adjustment. Flicker or noise sometimes appears on the viewfinder screen and
LCD monitor. This is not a malfunction.
t Even after automatic black balance has ended, if black shading is a cause for concern, select the [CAMERA] menu → [BLACK SHADING] →
[DETECTION], and adjust black shading. Alternatively, set to the [CAMERA] menu → [SW MODE] → [SHD,ABB SW CTL] → [ON] and hold down
the <AUTO W/B BAL> switch for two seconds or more to adjust black shading. [BLACK SHADING READY] will be displayed in the viewfinder, and
black shading can be automatically adjusted after the automatic black balance operation. While black shading is being adjusted, [BLACK SHADING
ACTIVE] will be displayed in the viewfinder. After this, be sure to close down the lens aperture until [BLACK SHADING OK] is displayed in the
viewfinder.
t When black balance is being automatically adjusted (when [ABB ACTIVE] is displayed in the viewfinder), adjustment is canceled by pushing the
<AUTO W/B BAL> switch towards <ABB> side again. The adjustment values will return to the values before automatic adjustment was performed.
