Sigma EF-530 DG Super Shoe Mount Flash for Sony Digital SLR's & Maxxum Cameras, Guide Number 174 feet at...

When there's insufficient or unsuitable light available to take a picture, it's of paramount importance to have a ready source of supplementary light to fulfill the need. That's where Sigma's EF-530 DG super-electronic flash comes into play. Designed exclusively for Sony digital SLR cameras, the flash offers a powerful guide number of 174 feet/53 meters and boasts the latest TTL automatic flash exposure control for easy operation. More significantly, the EF-530 is outfitted with a host of advanced features, including a modeling flash function, a multi-pulse flash, a TTL wireless flash, an FP (high-speed) flash, a rear-curtain synchro flash, and a manual flash mode that allows the photographer to set the flash power level by up to eight stops. The auto power-off function, meanwhile, automatically shuts off the display to save battery power. And when the flashgun is fully charged, the flash emits a confirmation-ready light, letting you check the flash exposure level through the camera's viewfinder. Like Sigma's lenses, the EF-530 flash incorporates the latest features and technological advances, most of which aren't found on any other flash units save those made by the major camera makers themselves. They are the most powerful and completely dedicated flash units available for 35mm SLR and digital cameras.
