Sigma EF-500 manual Attaching and Removing the Flash to and from the Camera, Wide Panel

ATTACHING AND REMOVING THE FLASH TO AND FROM THE CAMERA

Be sure 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 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 symbol appears. Each time you press the ZOOM button, the LCD panel display will change and indicate the zoom position in sequence, as follows.

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

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”).

WIDE PANEL

This flash is equipped with built in type wide panel, which can provide ultra wide 17mm angle of coverage. Slide out the wide panel and flip it down to cover flash’s head. Then the coverage angle setting of the flash will be set to 17mm automatically.

■If the built-in wide panel comes off accidentally, the ZOOM button will not function. In this case please contact the store where you have purchased the flash,
