Description
High-Frequency Anti-Flicker Shooting
Solution
High-Frequency Anti-Flicker Shooting
Images may be affected by banding if you shoot under light sources that flicker at high frequencies. High-frequency anti-flicker shooting enables you to take pictures at suitable shutter speeds for high-frequency flickering, which minimizes the effect of this flickering on images.
Caution
- Exposure in still photo shooting may vary.
- [HDR Mode shoot.] cannot be set to [Dynamic range] in high-frequency anti-flicker shooting.
- Before high-frequency anti-flicker shooting, consider setting [: Same expo. for new aperture] to [ISO speed].
-
Set the shooting mode to Tv or M.
- Turn the Mode dial to choose a shooting mode ().
-
Select [: HF anti-flicker shooting].
-
Select [HF anti-flicker shooting].
-
Select [Enable].
-
Select an item.

Auto Detecting
The camera detects 50.0–2011.2 Hz light sources and displays a suitable shutter speed for shooting under light sources that flicker at high frequencies. You can then switch to the indicated shutter speed.
-
Set the desired shutter speed.
- Set the shutter speed you would prefer to shoot at. For light sources that flicker at high frequencies, the camera will determine a suitable shutter speed near this value.
-
Select [Auto detecting].
-
Select [OK].
- It may improve HF flicker detection accuracy to magnify, as much as possible, any areas affected by banding.
-
Switch to the indicated shutter speed.
- Select [Yes] to switch to the indicated shutter speed.
- Selecting [Yes (move to Tv settings)] will display the [Manual setting] screen. Go to step 2 in Manual Setting.
-
Take the picture.
Caution
-
The range of the recommended shutter speed indicated varies by shutter mode.
- Electronic first-curtain: 1/50.0 to 1/512.0 sec.
- Electronic shutter: 1/50.0 to 1/2048.0 sec.
- Movie recording: 1/50.0 to 1/2048.0 sec.
-
Do the following if [No flicker detected] is displayed, or if switching shutter speeds does not eliminate banding.
- Perform automatic detection again
- Rotate the camera about 90° or switch to automatic detection in other ways
- Try the manual setting option
-
HF flicker detection may be less accurate under these conditions.
- Scenes with repetitive patterns (with a lattice or stripes, for example)
- Subjects in constant motion
- Extremely bright or dark scenes
- Scenes with multiple light sources
- Scenes with small flashing light sources
- Light sources flickering at lower frequencies
Note
- Movie display is not updated if high-frequency flickering is automatically detected during HDMI output of 4K movies.
Manual Setting
Check on the screen for image areas affected by light sources that flicker at high frequencies, then find a suitable shutter speed.
-
Select [Manual setting].
-
Adjust the shutter speed.
-
Take the picture.
