DESC: Canon's state of the art 580EX II Speedlite is fully compatible with the electronics of Canon EOS Digital & Film SLRs including Canon's E-TTL, E-TTL II & TTL dedication. This top-of-the-line flash is as good as it gets with more power, faster recycling time, more automatic and professional modes for creative effects, plus improved dust- and water-resistance. The 580EX II's auto-zoom head automatically adjusts to lenses from wide-angle to telephoto and a built-in ultra-wide angle panel provides flash coverage for a 14mm lens. The height of the 580EX helps to greatly reduce or eliminate red-eye and its flash head bounces and swivels for professional-looking portraits.
