<Notes>
OWhen using a lens with an auto aperture, check
that the lens connector has been connected.
OWhen using a lens with an auto aperture, the
aperture will be automatically set to where the light
is blocked while the black balance is being
adjusted.
OWhen using a lens with a manual aperture, the
aperture must be fully stopped down first before the
black balance is adjusted.
OWhile the black balance is being adjusted, the gain
selector circuit is switched automatically.
Flicker or noise may appear on the viewfinder
screen, but this is not indicative of malfunctioning.
OIf black shading is not satisfactory even with ABB
OK, open the BLACK SHADING screen of FILM
(CAM) MAIN MENU 4, and adjust the black
shading. (Refer to page 111.)
OWhen the super gain has been set to ON, the black
balance is executed at the preset position in the
white balance memory.
OWhen the AUTO W/B BAL switch is pressed again
to the ABB side when the black balance is being
adjusted automatically (ABB ACTIVE), the
adjustment operation will stop.
The adjusted value in this case is the value before
automatic adjustment was performed.
