If you shoot an image with a fast shutter speed under a light source
such as fluorescent light, the blinking of the light source causes flicker
and the image may be vertically unevenly exposed. If continuous
shooting is used under these conditions, uneven exposures or colors
across the images may result.
With anti-flicker shooting, the camera detects the frequency of the light
source’s blinking and takes the picture when the flicker causes less
effect on exposure or color.

When [ Enable ] is set and you shoot under a flickering light source, the
shutter-release time lag may become longer. Also, the continuous
shooting speed may become slightly slower, and the shooting interval
may become irregular.
This function does not work with Live View shooting and movie shooting.
In the <
d
> or <
f
> mode, if the shutter speed changes during
continuous shooting or if you shoot multiple shots of the same scene at
different shutter speeds, the color tone may be inconsistent. To avoid
inconsistent color tones, use the <
s
> or <
a
> mode at a fixed shutter
speed.
The color tone of images shot when [ Anti-flicker shoot. ] is set to
[ Enable ] may look different from when [ Disable ] is set.
Flicker at a frequency other than 100 Hz or 120 Hz cannot be detected.
Also, if the light’s flicker frequency changes during continuous shooting,
effects of the flicker cannot be reduced.
