Sigma EF-630 Manuel D'instructions page 25

WIRELESS MANUAL FLASH
As well as manual flash photography, wireless shooting
whereby the flash output can be manually set is also available.
In this case, two EF-630s (FOR SIGMA) are necessary.
MASTER UNIT SETTING
1. Set the Flash mode to [WL
2. In the Mode details area, adjust
the flash output so the actual
distance from the subject to the
slave flash matches the distance
indicated on the Status area.
3. Set the channel as needed.
(Select Ch.1 to Ch.3 in the Mode
details area.)
SLAVE UNIT SETTING
4. Set the Flash mode to [WL
].
SLAVE
5. In the Mode details area, set the
same channel as that of the
Master unit.
6. Position the flash for firing. Check the completion of charging
and start shooting.
It can also be used in combination with the EF-610 DG

SUPER SA-STTL. However in this case, use the EF-610 DG
SUPER as the Slave unit. (For setting this as the Slave unit,
please follow the EF-610 DG SUPER SA-STTL instruction
manual.) In this combination, the exposure may be
insufficient if the flash output is set near the maximum level.

MANUAL
SLAVE FLASH
The EF-630 includes a function which allows it to fire by
reacting to the flash from another flash unit. This allows for
easy and convenient shooting with the flash positioned at a
distance from the camera. The light output, however, is not
automatically adjusted in this mode.
NORMAL SLAVE FLASH
The Master unit attached to the camera can be used to trigger
a synchronized flash with the EF-630, even when it's
positioned at a distance from the camera.
The camera's built-in flash operates erroneously with the

pre-flash, therefore, synchronized flash is not possible.
Set the Master flash to manual mode and set the flash output
to approximately 1/16.
Set the camera's exposure mode to M, the shutter speed to
1/30 second or shorter, and the aperture and ISO at
discretional values.
1. Set the Flash mode of the Slave
EF-630 to [S-FL
NORMAL
2. In the Mode details area, set the
ISO and the aperture values to
match those of the camera settings.
3. Adjust the flash amount in the Mode details area so the
distance between the Slave flash and the subject is
approximately the same as the distance indicated in the
Status area.
4. Check the completion of charging and start shooting.
