SLAVE FLASH
NORMAL SLAVE FLASH
Even if the EF-610 DG SUPER SA-STTL is not attached to the camera body, you can fire the flash by
using the camera’s built-in flash or another flash unit.
1. Attach the flash unit to the camera’s hot shoe.
2. Set the camera’s exposure mode to the desired mode. If you use A or M mode, also set the
desired aperture value.
3. Turn on the flash unit. Then press the shutter button half way.
■ Now, the aperture value and film speed are automatically
transmitted to the flash unit.
4. Remove the flash unit from the camera.
5. Press the MODE button and select the / (Slave)
mode.
6. Press the SEL button several times to make the flash output
value indicator blink.
7. Press the + or – button to set the flash output amount.
■ Determine the appropriate flash output by setting the distance indicator on the LCD panel to coincide
as closely as possible, with the actual distance from the slave flash to the subject. If the actual
distance is out of range, you will need to change the aperture value or film speed.
■ You can set the film speed or aperture value on the flash unit manually, if desired.
a. For the film speed … Press the MODE to select the ISO, then press the SEL button to make
the indicator blink. Press the + button or – button and set the desired film speed, then
press the SEL button once again.
b. For the aperture value … When the flash unit is set to the Slave mode, press the SEL button to
make the indicator for the aperture value blink, and press the + button or – button to set
the desired aperture value. Then press the SEL button.
8. Press the SEL button several times to make the display stop blinking.
9. Place the slave unit in the desired location. Do not place the slave unit within the picture area.
10. After confirming that all flash units are fully charged, press the shutter button to take the picture.
■ When using the EF610 DG SUPER SA-STTL flash as the "Slave Controller" (on SD9, SD10, SD14
or SD15 camera) in Normal Slave mode, please set the flash to "Manual" mode, and adjust the light
output to 1/16 power. If you set it to TTL mode instead, the Pre-Flash system will function, causing
the "Slave" (off-camera) flash unit to fire prematurely.
■ When the EF-610 DG SUPER SA-STTL is fully charged, the AF Auxiliary Light will blink.
■ The flash will not fire if the EF-610 DG SUPER SA-STTL is attached to the camera body while it is in
the Slave Mode setting.
DESIGNATED SLAVE FLASH
If using two or more EF-610 DG SUPER SA-STTL flash units, you can designate which flash will fire
together by using the channel settings. In this mode, one flash unit will be used as the Slave Controller
and the others for firing as Slaves.
Setting the Slave Flash unit(s) for firing
1. Attach the slave unit to the camera body.
2. Set the camera’s exposure mode to S or M.
■ Set the shutter speed to 1/30 or slower. (The slave controller unit (Master Flash) will transmit the
designated signal before the others fire. Thus if you use a shutter speed faster than 1/30, the firing
flash units will not be synchronized.)
