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

  • Flicker can cause uneven exposure or (in photographs taken in continuous release modes) inconsistent exposure or coloration.

  • Note that the frame rate for burst shooting may drop or become erratic when [On] is selected.

  • Depending on the light source, flicker reduction may slightly delay shutter response.

  • Flicker reduction can detect flicker at 100 and 120 Hz (associated respectively with AC power supplies of 50 and 60 Hz). The desired results may not be achieved if the frequency of the power supply changes during burst photography.

  • Flicker may not be detected or the desired results may not be achieved depending on the light source and shooting conditions, for example with scenes that are brightly lit or feature dark backgrounds.

  • The desired results may also not be achieved with decorative lighting displays and other non-standard lighting.
