The Speedlite 580EX is the new-top-of-the-line flashgun from Canon. Although suitable for all EOS cameras, it has been optimised for use with digital models. It provides full compatibility with the distance-linked E-TTL II flash system found on recent EOS cameras, and automatically adjusts to provide optimum coverage for the sensor size of the latest digital cameras. The guide number, at a maximum of 58 (ISO 100m), is the highest of any Canon flashgun. Wireless transmission is built-in. Accessories include a new Compact Battery Pack CP-E3 and Canon’s first Speedlite Bracket SB-E1. The Speedlite 580EX is a successor to the Speedlite 550EX.
