External flash shooting
With this camera, you can use one of the separately sold external flash units to achieve
a flash suited to your needs. The external flashes communicate with the camera,
allowing you to control the camera’s flash modes with various available flash control
modes, such as TTL-AUTO and Super FP flash.
An external flash unit specified for use with this camera can be mounted on the camera
by attaching it to the camera’s hot shoe. You can also attach the flash to the flash
bracket on the camera using the bracket cable (optional). Refer to the documentation
provided with the external flash units as well.
