White Shading Adjustment
It is necessary to perform this adjustment to the camera
when attaching a lens that is different from the previously
attached lens.
Even if white balance is achieved in the middle of the screen,
it may not be achieved at the top and bottom of the screen.
Greens and magentas may be colored. This is due to char-
acteristics of the lens. Correcting this phenomenon is called
White Shading Adjustment.
Perform this after adjusting white balance.
White shading adjustment is performed on the WHITE BAL-
ANCE menu screen.
Adjustment procedure

White balance the camera.
2.
Set the camera’s lens controls as follows:
a.Set the IRIS opening to F4 or higher number.

of its range.

itor screen with it.

ment.
