Using P-TTL Mode
You can use the P-TTL auto flash with the AF540FGZ, AF360FGZ,
AF200FG or AF160FC flash unit.
1
Remove the cover of the hot shoe, and attach the external flash.
2
Turn on the camera and the external flash.
3
Set the external flash mode to [P-TTL].
4
Confirm that the external flash is fully charged, and then take a picture.
• The maximum sync speed available with an external flash is 1/250 sec.
• P-TTL auto flash is only available with an AF540FGZ, AF360FGZ, AF200FG or AF160FC flash unit.
• For details such as operation method and effective distance, please refer to the external flash manual.
• The flash does not discharge if the subject is bright enough when the flash mode is set to C or i. Therefore, it may not be suitable for daylight-sync shooting.
• Never pop up the built-in flash manually when any external flash unit is attached to the camera. The built-in flash will hit the external flash.

Red-eye Reduction
As with the built-in flash, the red-eye reduction function is available with an external flash. The red-eye reduction function works by discharging the flash twice even when only an external flash is used.
However, this function may not be available on some flashes or may
have restrictions for usage conditions. Refer to the chart on p.215.
