Electronic Flash EF-530 DG ST can be used with Sigma’s and other manufacturers’ AF 35mm SLR cameras and Digital SLR cameras. This flashgun is designed to allow TTL auto flash photography with 35mm SLR cameras and Digital SLR cameras.

Autozoom function for changing the illumination angle in accordance with the lens’ angle of view This function automatically sets the optimum illumination angle in accordance with the lens’ focal length in a range from 24 mm to 105 mm. When the built-in Wide Panel is used, the flash can cover the angle of up to that of a 17mm lens. Due to the smaller size of image sensors in most digital SLR cameras, the coverage angle of the flash can effectively reach a wider coverage angle.

The flash head can be tilted up by upto 90 , to the left by 180 , or to the right by 90 . Bounce photography, in which light is reflected off a white wall or the ceiling or a reflector, increases your range of photographic expression. As the flash head can also be tilted down by 7 , light can also be used for close-up shots.

In manual flash mode, you can set the flash power level of the EF-530 DG ST with two levels : Full power and 1/16.

AF may not work appropriately in a dark place. However, the AF auxiliary light mechanism of EF-530 DG ST lets you control AF even in situations where autofocusing is difficult. (With some cameras, AF auxiliary light may not work, please refer to a compatibility table)

Even if the flash is left with the power on, it automatically shuts off, if it is not operated for a certain length of time. This conserves battery power in flash photography. When the shutter button is depressed halfway, the power turns on again, and charging resumes.
