Using the Flash
You can connect an external flash to the
camera with a sync cord by using the X-sync
socket.
Remove the Sync socket 2P cap and
connect a sync cord to the X-sync socket.
When using two or more external flashes and the contrast-control-sync mode
is set on the external master flash unit, the flash output ratio is 2 (master unit)
: 1 (slave units). When an external flash is used in combination with the built-
in flash, the flash output ratio is 2 (external flash) : 1 (built-in flash).
When using multiple external flashes or using an external flash with the built-
in flash, P-TTL is used for flash control.
X-sync Socket
The use of high-voltage or high-current external flashes may cause a camera
breakdown.
Flashes with reversed polarity (the center of the sync plug is minus) cannot
be used due to the risk of damaging the camera and flash.
When a sync cord is connected to the X-sync socket, linked functions will not
work.
To prevent vignetting caused from Trailing Curtain Sync, it is recommended
to take a test shot using a shutter speed one level slower than the flash sync
speed.
The contact of the X-sync socket is not dust-proof and water-resistant. Attach
the provided Sync socket 2P cap when not in use.
