The EF-530 Super DG is Sigma's flagship TTL flash, and has been updated with improved coverage range and a stronger power output. It features a powerful Guide Number of 174'/53 m at 105mm, and covers a focal range from 24mm to 105mm.
The EF-530 Super DG is also fully compatible with the latest digital SLR cameras that use a pre-flash, and supports full i-TTL operation (where supported by camera). You will find features designed for the professional, at a much more attractive price than the comparably equipped manufacturer's flashes. The perfect all-around flash for any digital or 35mm autofocus SLR shooter.
