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.
- 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.
Select [: HF anti-flicker shooting].
Select [HF anti-flicker shooting].
Select an item.
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].
- 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.
The range of the recommended shutter speed indicated varies by shutter mode.
- Mechanical shutter: 1/50.0 to 1/1024.0 sec.
- 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
- Movie display is not updated if high-frequency flickering is automatically detected during HDMI output of 4K movies.
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.
Do the following if banding is not eliminated at the shutter speed set with automatic detection.
- Turn the dial. With the dial, you can increase the shutter speed set with automatic detection (×2, ×3, ×4, and so on) or decrease it (1/2×, 1/3×, 1/4×, and so on).
- Turn the dial to fine-tune the setting.
- If this does not eliminate banding, rotate the camera about 90° or switch to automatic detection in other ways.
Take the picture.
The shutter speed range available for the manual setting mode varies by shutter mode.
- Mechanical shutter: 1/50.0 to 1/2048.0 sec.
- Electronic first-curtain: 1/50.0 to 1/2048.0 sec.
- Electronic shutter: 1/50.0 to 1/8192.0 sec.
- Movie recording: 1/50.0 to 1/8192.0 sec.
- Maximum flash sync speed in flash photography is limited to 1/181.0 sec. regardless of shutter mode.
- Dark lenses may prevent correct display simulation.
- Safety shift in M mode adjusts the aperture value as needed in high-frequency anti-flicker shooting.
- Image display on the screen or in the viewfinder may differ from actual shooting results. Take some test shots in advance.
