D Auto FP High-Speed Sync Depending on the shutter speed, horizontal lines may appear in pictures taken using auto FP high-speed sync when [1/250 s (Auto FP)] or [1/200 s (Auto FP)] is selected. This effect can be mitigated by: • choosing a slower shutter speed or • adjusting flash output. A Auto FP High-Speed Sync Auto FP high-speed sync allows the flash to be used at shutter speeds as fast as 1/8000 s. When [1/250 s (Auto FP)] or [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. 638 A Custom Settings: Fine-Tuning Camera Settings
