Auto Distortion Control; Flicker Reduction Shooting - Nikon Z fc N2016 Reference Manual

Auto distortion control

Select [On] as required to reduce barrel distortion when shooting with
wide-angle lenses and to reduce pin-cushion distortion when shooting
with long lenses. Note that [On] may be selected automatically with
some lenses, in which case this item will be grayed out and unavailable.

Flicker reduction shooting

When [On] is selected, reduce the effects of flicker from such light
sources as fluorescent or mercury-vapor lamps.

continuous release modes) inconsistent exposure or coloration.

erratic when [On] is selected.
