User manual SIGMA EM-140 DG SA-STTL

[. . . ] Do not use this flash unit on any camera other than the SIGMA SD, SA series cameras; otherwise the flash may damage the circuitry of these cameras. When using the flash and camera in the rain or snow or near water, keep it from getting wet. When the flash is subjected to sudden temperature change, as when the flash unit is brought from a cold exterior to warm interior, condensation might form inside. In such a case, place your equipment in a sealed plastic bag before such a change, and do not use the flash unit, until it reaches room temperature. [. . . ] If the camera's built-in flash is set in up position, please close it before you attach the flash unit. While pressing the left and right release tabs on both sides of the holder, place the flash unit over the adapter, then release both tabs. When you press the LIGHT button, the LCD panel will illuminate for about 8 seconds. The illumination stays on longer than 8sec, if you press the LIGHT button once again. In a dark place, it will be easy to focus by using the auxiliary light. This fuction is very convenient when composing pictures where auto focus does not operate well or where focus adjusment in manual is difficult. Turn on the power switch of the flash, the TTL mark will appear on the LCD panel and flash will start charging. (If TTL mark does not appear, depress the MODE button several times to select the TTL mode). Check that the subject is located within the effective distance range, indicated on the LCD panel. When the flash is fully charged, the ready light in the viewfinder, and appears on the flash unit. If this indication does not appear, the flash illumination is not enough for that situation. if the SA-300 , SA-300N and SA-5 cameras , are set to " " fully automatic mode , Flash will automatically switch to TTL mode only. For other camera exposure modes, the flash will be set to the last chosen mode each time. when the flash is fully charged , the flash mark will appear in the finder. If the shutter is released before the flash is fully charged, the flash will not fire, and the camera will take the picture at a slow shutter speed. It is possible to give the three dimensional effect to your pictures by adjusting the flash ratio of left or right flash tube or by firing only one side of the flash. Pressing + button will increase the left flashtube and pressing ­ button will increase the power amount of the right flashtube. (flash ratio will not be displayed and only firing side will blink) 5. If the flash ratio is set to 1:1 or the mode is changed, this function will be cancelled. By doing this flash unit will be set to default mode, display will show both sides. By selecting the S mode of the camera, you can set the shutter speed from 30sec. When you set the desired shutter speed, the camera will select the appropriate aperture value for the background. [. . . ] The slave Controller 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. Now, aperture value and film speed are automatically transmitted to the slave flash unit. Set the flash power 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. [. . . ]
