Anti-flicker shooting

Several EOS cameras feature a flicker reduction option that is usually set by default. This is shown often by “Flicker” being visible in the viewfinder on models such as the EOS-1D X Mark II, EOS 5D Mark IV and EOS 7D Mark II. With this enabled, the camera will aim to only shoot at the peak of the frequency of artificial lighting. Under fluorescent lighting, for example, this avoids a white balance or exposure shift between frames as the light colour and intensity changes during the refresh cycle. With this setting enabled you may find the frame rate of your camera reduces from the maximum possible. If so, and you need the fastest frame rate, then disabling Anti Flicker Shoot will provide that – at the possible expense of frames where the colour or the exposure is inconsistent.
