• The built-in flash will not discharge if the camera is connected to an external flash.

• Flashes with reversed polarity (the center contact on the hot shoe is minus) cannot be used due to the risk of damaging the camera and flash.

• When an external flash is attached directly to the hot shoe of the camera, the camera’s center of gravity is greatly shifted, making it difficult to take pictures.

When using an external flash, it is recommended to use an extension cord to

separate the camera and flash. (p.217)

• To use an AF160FC flash with the camera, a commercially available step-up ring or similar accessory is needed.

Using P-TTL Mode

You can use the P-TTL auto flash with the AF540FGZ, AF360FGZ,

AF200FG or AF160FC flash unit.

Remove the cover of the hot shoe, and attach the external flash.

Turn on the camera and the external flash.

Set the external flash mode to [P-TTL].

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.

Connecting an External Flash with an

Extension Cord

Attach the Hot Shoe Adapter F

(optional) to the camera hot shoe and an

Off-Camera Shoe Adapter F (optional) to the bottom of the external flash, and connect these with the Extension Cord F5P (optional) as shown in the illustration below. The Off-Camera Shoe Adapter F can be mounted to your tripod using the tripod screw.

The built-in flash will not discharge if the camera is connected to an external flash.

• Do not combine with accessories that have a different number of contacts, such as a Hot Shoe Grip, as a malfunction may occur.

• Combining with flashes from other manufacturers may cause equipment breakdown.
