Canon Speedlite 580EX User Manual.pdf

Before using the Speedlite, read this guide and instruction manual of your camera to familairize yourself with Speedlite operation. Basic operation is the same as firing a normal AE. When the 580EX is attached to the EOS camera, almost all automatic exposure control to be handled by the camera flash photography. This is almost the same as using the camera's built-in flash if you have one. You can think of 580EX as a flash built-in, high-output. This is automatically compatible with the camera flash metering mode (E-TTL II, E-TTL, and TTL).
