Product Description The EF-610 DG ST is multifunctional shoe mount type flash, featuring a powerful Guide Number of 61 and designed to work with the most popular digital SLR cameras. This flash unit provides fully automatic flash photography for digital SLRs with automatic TTL exposure control. It combines a convenient array of functions with ease of handling, and includes an Autozoom head that automatically sets the optimum illumination angle between 24mm and 105mm, as well as offering bounce and swivel capability. The EF-610 DG ST is designed to work with the latest TTL auto exposure systems of most popular manufacturers` digital SLR cameras. The camera will control the amount of flash lighting to achieve the appropriate exposure for the subject. This function automatically sets the optimum illumination angle in accordance with the lens' focal length in a range from 24mm to 105mm. When the built-in Wide Panel is used, the flash can cover an angle of up to that of a 17mm lens. The flash head can be tilted up as much as 90°, and swivel 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°, the flashgun can also be used for close-up photography. This flash is equipped with a built-in catch light panel, which can create a sparkle in the eyes of the subject when the bounce flash mode is activated. AF may not work efficiently in a dark place. However, the AF auxiliary light mechanism of the EF-610 DG ST lets you control AF even in situations where autofocusing is difficult. In manual flash mode, you can set the flash power level of the EF-610 DG ST with two levels: Full power and 1/16. Even if the flash is left with the power switched on, it automatically shuts off if left unused for a certain length of time. This conserves battery power in the flashgun. When the shutter button is depressed halfway, the power turns on again and charging resumes. Box Contains Sigma EF-610 DG STFitted CaseFlash Stand (FS-11)Instruction Manual1 Year Warranty Card
