This QuickGuide will explain how to use the Integrated Speedlite Transmitter feature incorporated in Canon EOS 7D, 60D, and Rebel T3i (660D) cameras. This feature uses the camera’s built-in flash unit to wirelessly trigger one or more off-camera (receiver) Speedlites, either individually or in groups. Compatible Speedlites include the 580EX II, 430EX II, 320EX, and 270EX II.
