The EF-500 Super DG is Sigma's flagship TTL flash , and has now been updated to also be fully compatible with Digital SLR cameras that use a pre-flash, and supports full E-TTL II 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.
