Auto FP High-Speed Sync
Auto FP high-speed sync allows the flash to be used at the highest
shutter speed supported by the camera, making it possible to choose
the maximum aperture for reduced depth of field even when the subject
is backlit in bright sunlight. The information display flash mode
indicator shows “FP” when auto FP high-speed sync is active.
