The Speedlite 580EX is a high-end on-camera flash for Canon EOS cameras.  It's a strong and capable flash that offers convenient refinements and improvements over Canon's previous top of the line 550EX flash.

Canon's top-of-the-line Speedlite has been thoroughly revised. It's smaller and lighter than ever, yet provides a bit more power with significantly faster recycling.  A new Select Dial makes changes, like exposure compensation, a breeze.  It now covers lenses as wide as 14mm and has new features for digital SLRs - including the ability to transmit precise flash color temperature information and vary the zoom setting to match the imaging sensor size.
