When high-frequency flicker reduction is enabled, the shutter
speed display shows only the denominator
, with a digit added
after the decimal point.

Selecting [On (shutter speed fine-tuning)] allows shutter speeds between ¹⁄₈₀₀₀ and ¹⁄₃₀s to be
adjusted in smaller increments in modes S and M, letting speeds that keep flicker to a minimum be
found by viewing the preview in the shooting display.
Flicker may cause banding in pictures taken under high-frequency LED lighting or in shots that
include monitors with high-frequency LED displays. Reducing the size of the increments used for
shutter-speed selection helps in identifying speeds that keep flicker to a minimum.
After choosing a shutter speed suited to your subject, enable high-frequency flicker reduction and
fine-tune shutter speed while viewing your subject in the shooting display until you find a value that
minimizes flicker and banding. The effect can be more readily ascertained by zooming in on your
subject using display zoom.
The precise shutter speed is shown. For example, the shutter speed when ¹⁄₅₀₀ s is selected is
precisely ¹⁄₅₁₂ s, which the display shows as “512.0”, the denominator.
Turning high-frequency flicker reduction off returns shutter speed to the nearest of the values
normally displayed.
