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
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 28mm). 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”).
