Caution: Auto FP High-Speed Sync
Depending on the shutter speed, horizontal lines may appear in pictures taken using auto FP high-speed sync when [1/200 s (Auto FP)] is selected. This effect can be mitigated by:
- choosing a slower shutter speed or
- adjusting flash output.
Choosing a Fixed Flash Sync Speed
To fix shutter speed at the value selected for Custom Setting e1 [Flash sync speed] in modes S and M, rotate the shutter speed dial to X. An X (flash sync lock) icon will appear with the flash sync speed in the shooting display.
Auto FP high-speed sync allows the flash to be used at shutter speeds as fast as ¹⁄₈₀₀₀ s (or ¹⁄₂₀₀₀ s if [Electronic front-curtain shutter] is selected for Custom Setting d5 [Shutter type]). When [1/200 s (Auto FP)] is selected, the camera automatically enables auto FP high-speed sync at shutter speeds faster than the flash sync speed. This makes it possible to choose the maximum aperture for reduced depth of field even when the subject is backlit in bright sunlight.
