Reduce the effects of flicker from such light sources as fluorescent or mercury-vapor lamps during viewfinder photography. Flicker can cause uneven exposure or (in photographs taken in continuous release modes) inconsistent exposure or coloration.



[Flicker reduction setting]

When [Enable] is selected, the camera will time photographs to reduce the effects of flicker.

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

[Flicker reduction indicator]

Choose whether a FLICKER icon is displayed in the viewfinder when flicker is detected.

  • Selecting [Enable] for [Flicker reduction setting] and [On] for [Flicker reduction indicator] during viewfinder photography causes the FLICKER icon to be displayed if flicker is detected when the shutter-release button is pressed halfway. If [Disable] is selected for [Flicker reduction setting], the FLICKER icon will flash.

Flicker Reduction: Restrictions

The [Flicker reduction] item in the photo shooting menu does not take effect under some conditions, including:

  • during live view photography or when

  • Mup
    is selected for release mode,

  • [On] is selected for [Silent photography] in the respective sub-menu during interval-timer photography, time-lapse movie recording, or focus shift,

  • HDR is enabled,

  • exposure delay mode is on, or

  • shutter speed is set to A (“Bulb”) or % (“Time”).

Flicker Reduction
  • Take a test shot and view the results before taking additional photographs.

  • Depending on the light source, flicker reduction may slightly delay shutter response. During burst shooting, the frame rate may slow or become erratic.

  • 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.
