Choose the flash sync speed.

  • 1/200 s (Auto FP): Selecting this option (available only when an optional flash unit is attached) enables auto FP high-speed sync with compatible flash units; the maximum sync speed for other flash units is set to 1/200 s. When the camera shows a shutter speed of 1/200 s in mode P or A, auto FP high-speed sync will be activated if the actual shutter speed is faster than 1/200 s, and shutter speeds as fast as 1/4000 s can be selected by the camera (modes P and A) or by the user (modes S and M).
  • 1/200 s–1/60 s: Set the maximum flash sync speed to the selected value.

Auto FP High-Speed Sync

Auto FP high-speed sync allows optional flash units 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 in bright sunlight.
