Anti-flicker Set.

still image, movie, slow&quick motion

To reduce the impact of flickering from artificial light sources (such as fluorescent or LED light), the camera can time the shooting of images to moments when flickering will have less of an impact, or you can set the shutter speed more finely than usual.

This function reduces differences in exposure and color tone between the upper and lower area of an image during continuous shooting under artificial light sources.

  1. MENU → (Shooting) → [Shutter/Silent] → [Anti-flicker Set.] → desired setting item.

Menu item details

Anti-flicker Shoot. (only when shooting still images):
Detects flickering and reduces its impact when the frequency of the light source is 100 Hz or 120 Hz while shooting still images. Flicker is detected by pressing the shutter button halfway down. ([On]/[Off])
When [Anti-flicker Shoot.] is set to [On], press the shutter button halfway down and shoot the image after confirming that (flicker icon) is displayed.
Var. Shutter:
Reduces the differences in brightness between each image by finely adjusting the shutter speed according to the flickering frequency. ([On]/[Off])
[Var. Shutter] can only be selected when the camera is in an exposure mode that allows you to manually adjust the shutter speed (both still images and movies).

When [Var. Shutter] is set to [On], the shutter-speed denominator is displayed in the decimal format (high-resolution shutter speed).
For example, if the normal shutter speed is set to 1/250 second, the value will be displayed as 250.6. (The numbers may differ from the actual ones.)

  • Set [Var. Shutter] to [Off] to return to the original display.
Var. Shutter Set.:
Sets the shutter speed when [Var. Shutter] is set to [On].
Select a shutter speed that reduces the impact of flickering while checking the monitor. Press the center of the control wheel to automatically set the shutter speed so that the impact of flickering is reduced. The faster you set the shutter speed, the more likely there is to be a difference between the monitor display before shooting and the recorded image. Make sure that the impact of flickering is reduced in the recorded image.

Hint

  • When [Anti-flicker Shoot.] is set to [On], the color tone of the resulting image may vary if you shoot the same scene using a different shutter speed. In this case, we recommend that you shoot in the [Shutter Priority] or [Manual Exposure] mode with a fixed shutter speed.
  • When [Anti-flicker Shoot.] is set to [On], you can perform anti-flicker shooting by pressing the AF-ON (AF On) button.
  • When [Anti-flicker Shoot.] is set to [On], you can perform anti-flicker shooting by pressing the shutter button halfway down or pressing the AF-ON (AF On) button, even in the manual focus mode.
  • When [Anti-flicker Shoot Sel.] or [Var. Shutter Select] is assigned to a custom key, you can switch the [Anti-flicker Shoot.] or [Var. Shutter] function on and off by pressing the key.
  • When [Anti-flicker Tv Scan] is assigned to a custom key, you can make the camera automatically set the shutter speed to reduce the impact of flickering by pressing the key while shooting.
  • On the [Var. Shutter Set.] screen, you can finely adjust the high-resolution shutter speed using the rear dial L, rear dial R, or control wheel as in the following example.
    250.6 → 253.3 → 256.0 → 258.8*
    You can change the high-resolution shutter speed to an integral multiple value using the front dial, as in the following example.
    125.3 (2 times) ← 250.6 → 501.3 (1/2 times) *

    *The numbers may differ from the actual ones.

  • When [Var. Shutter] is set to [On], the high-resolution shutter speed can be finely adjusted on the shooting standby screen. If you want to change the high-resolution shutter speed to an integral multiple value even on the shooting standby screen, assign [Shutter Speed(step)] to a custom key or the “My Dial” setting.
  • When you change the [Var. Shutter] setting from [On] to [Off], the high-resolution shutter speed switches to the closest value among normal shutter speeds.

Note

  • When you set [Anti-flicker Shoot.] to [On], the image quality of the live view is reduced.
  • When you set [Anti-flicker Shoot.] to [On], the shutter release lag may increase slightly. In the continuous shooting mode, the shooting speed may slow down or the interval between shots may become irregular.
  • Even when [Anti-flicker Shoot.] is set to [On], the camera may be unable to detect flickering depending on the light source and shooting conditions, such as a dark background. Also, even if the camera detects flickering, its impact may not be reduced sufficiently depending on the light source and the shooting situation. We recommend that you take test shots beforehand.
  • [Anti-flicker Shoot.] is not available when shooting in the following situations:
    • While bulb shooting
    • [Shutter Type] is set to [Electronic Shutter]
    • Movie shooting mode
  • The color tone of the shot results may differ depending on the setting of [Anti-flicker Shoot.].
  • Setting [Anti-flicker Shoot.] to [On] may not decrease flicker on the live-view screen during continuous shooting.
  • When [Var. Shutter] is set to [On], the release time lag may be longer.
  • Even when [Var. Shutter] is set to [On], depending on the frequency of the light source, you may be unable to set the appropriate shutter speed and eliminate the impact of flickering. In that case, try the following.
    • Setting a slower shutter speed
    • Switching to another shutter type
  • When you press the shutter button halfway down, flickering may appear temporarily.
  • High-resolution shutter speed setting values cannot be registered to [Reg. Custom Shoot Set]. The default shutter speed value will be applied instead.
  • When [Var. Shutter] is set to [On], the flash sync speed may be limited to the slower side.
