ADJUSTING THE FLASH HEAD
Depress the Bounce “Up and Down” Lock and Release Button,
and adjust the flash head to the desired position.
■ If
appears on the LCD panel when you turn on the flash, and
if this mark blinks, then the flash head is adjusted to an incorrect
position.
ATTACHING AND REMOVING THE FLASH TO AND FROM THE CAMERA
Be sure to turn off the Power Switch, Then insert the
Shoe Base into the hot shoe on the camera and turn
the Shoe Locking Ring until it is tight.
■ When you attach or remove the flash, grasp the
bottom of the flash to prevent damage to the shoe
foot and the camera’s hot shoe.
■ If the camera’s built-in flash is set in up position,
please close it before you attach the flash unit.
■ To remove the flash, rotate the shoe-locking ring in
the opposite direction of ◄LOCK mark, until it stops.
SETTING OF FLASH COVERAGE ANGLE
When you press the ZOOM button, the symbol appears. Each time you press the ZOOM button,
the LCD panel display will change and indicate the zoom position in sequence as follows.
24mm → 28mm → 35mm → 50mm → 70mm → 85mm → 105mm → ( Auto)
Generally, in the TTL mode, the flash will automatically set the zoom position according to the focal
length of your lens.
■ When you turn on the main switch, the flash will memorize and set the zoom head position to the last
setting used.
■ If you use a lens wider than the flash head setting, there may be under exposed areas around the
edge of the picture.
■ Depending on the flash head setting, the flash’s Guide Number will be changed.
In the case of use with Sigma SD9 SD10 SD14 SD15
Due to the size of the camera’s image sensor, when the coverage angle of the flash is set to auto
zoom, coverage angle can effectively reach that of 17mm wide focal length, without using the wide
panel, (However, the coverage angle display of the flash will not show wider than 24mm). When the
wide panel is used, 10mm focal length can be covered. (However, the coverage angle display on the
flash will show 17mm.)
When "Manual Flash photography" or "FP Flash photography" is performed, the flash’s coverage
angle can be set automatically by the flash’s autozoom function. However, when used with the camera,
the effective range of the flash’s light can be extended by increasing the zoom setting of the flash to be
equal to the effective focal length of the lens being used by using the ZOOM button. Please refer to
the following table as a guide in setting the flash to the appropriate zoom setting. Please use this
table in conjunction with Table 1 (“Guide Number Table for Manual Flash”) on the last page of this
instruction manual, and Table 2 (“Guide Number Table for FP Flash”).
