Differences between the [Anti-flicker Shoot.] and [Variable Shutter] functions

This camera has two different functions to reduce the impact of flickering from artificial light sources (such as fluorescent or LED light).
The features of each function and the corresponding shooting conditions are as follows.

Features and shooting conditions Anti-flicker Shoot. Variable Shutter
Features The camera can time the shooting of images to moments when flickering will have less of an impact by detecting the flickering frequency automatically. You can manually adjust the shutter speed while checking the impact of flickering on the monitor.
Still images/movies Still images only Still images/movies
Shutter type Electronic shutter/mechanical shutter Electronic shutter/mechanical shutter*1
Exposure mode P (Program Auto) / A (Aperture Priority) / S (Shutter Priority) / M (Manual Exposure) S (Shutter Priority) / M (Manual Exposure)/[Flexible Exp. Mode] with the shutter speed adjusted manually
Types of flickering detectable Flickering with a frequency of 100 Hz or 120 Hz (such as fluorescent light) only *2 Flickering with a frequency of 100 Hz or 120 Hz (such as fluorescent light) and flickering with a frequency higher than 100 Hz or 120 Hz (such as LED light)

*1The 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.

*2 Even when [Anti-flicker Shoot.] is set to [On], the camera cannot detect flickering frequencies other than 100 Hz or 120 Hz.


  • The impact of flickering can be reduced by using [Anti-flicker Shoot.] and [Variable Shutter] together even in a shooting environment where both 100 Hz/120 Hz flickering and higher-frequency flickering occur. In this case, first set [Anti-flicker Shoot.] and [Variable Shutter] to [On], and then adjust the shutter speed with [Var. Shutter Set.] before shooting images.
