The Sigma EF-610 DG ST is multifunctional shoe mount type flash, designed to work with digital SLR cameras of most popular manufacturers and features a powerful Guide Number 61. This flash unit provides fully automatic flash photography for digital SLR cameras with automatic TTL exposure control. It combines a convenient array of functions with ease of handling, and include an Autozoom function 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.
The flash head can be tilted up by as much as to 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 shots.
Like a studio flash unit equipped with a modeling lamp, the EF-610 DG SUPER also offers a modeling flash function, enabling the user to check for intense reflections and shadows before taking the flash photograph.
*In the case of Canon fitting flashguns, it can only be used with Canon cameras equipped with a Modeling Flash function.
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.
