is set to the setting other than the
maximum setting(+16) and the
display screen is seen through
the camera, the flicker appears.
The symptom occurs because the factory setting(Standard mode) of the
backlight is (+8). The backlight control is controlled by PWM dimming
(pulse dimming), and if the setting of the backlight is lowered, the period of
the pulse decreases and it interferes with the shutter cycle of the camera.
