Sigma ELECTRONIC FLASH EF-610 DG SUPER NA-iTTL (ニコン用): WIRELESS FLASH

WIRELESS FLASH

When using the “Wireless Flash” mode, you can take pictures with a more three-dimensional feeling

with shadow, or you can produce natural images with shadow depending on the flash position without

any extension cord connecting the camera body to the flash. In case of the EF-610 DG SUPER

NA-iTTL, communication between the camera body and the flash will be achieved by the light of the

flash. In the “Wireless Flash” mode, the camera will calculate the correct exposure automatically.

◆ This function is available with CLS compatible cameras only.

◆ If the camera body incorporates Commander mode, it is possible to use its own built-in flash for wireless

photography.

◆ In these instructions, we call a flash unit, which is attached to the camera body the “Master unit ”, and we call

a flash unit at a remote position a “Slave unit”.

◆ When setting a slave unit at the desired position, you can use a mini-stand. This mini-stand has a screw hole

for a tripod.

◆ Place the slave flash unit at the desired location. Do not place the slave unit within the picture area.

◆ Set the flash unit within the range of 0.5m/1.5ft~5m/16ft from the subject and set the camera body within the

range of 1m/3ft~5m/16ft from the subject.

◆ Two or more sets of Slaves can be divided into groups and different flash conditions can be set for each group

(1~3). The Master Flash should be set at 0.

◆ Channel and group number settings can be input on the master unit and slave units. Other settings can be

input on the master flash unit only.

Setting the slave unit

1. Attach the flashgun to the camera body and switch “ON” the flash unit.

Press the MODE button to select the TTL /

/

icon.

◆ Setting cannot be done if camera’s exposure display turns off. In such a

case, press the camera’s shutter button half-way to re-activate the setting.

2. Press the SEL button to make the channel indicator blink and press the

+ or – button to set the channel number (from C1- C4).

3. Press the SEL button to make the group number blink and press the + or – button to set the group

4. Detach the slave unit from the camera body and place it in the desired position.

◆ In the case of using the built-in flash of a camera body with Commander mode for wireless photography,

Group A cameras correspond to Group 1 flashguns and Group B corresponds to Group 2 flashguns. When

using the built-in flash unit of the D70 for wireless photography, set the channel number to C3 and group

number to 1. For the rest of the settings, refer to your camera’s instruction manual. Please also note that it

cannot be used with camera’s command mode AA and M1/128.
