D Caution: Auto FP High-Speed Sync
Depending on the shutt
er 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.
Tip: 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.
Tip: Auto FP High-Speed Sync
Auto FP high-speed sync allows the flash to be used at shutt
er 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.
