Canon Speedlite 580EX Black

Canon's top-of-the-line Speedlite has been thoroughly revised. It's smaller and lighter than ever, yet provides a bit more power and 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.
