External Speedlites - Canon EOS 50D Instruction Manual

External Speed lites
EOS-dedlcated,EX"series SpeedHtes
Basically operates like a built-in flash for easy operation.
When an EX-series Speed lite is attached to the camera, almost all the
autoflash control is done by the camera. In other words, it is like a high-
output flash attached externally in place of the built-in flash.
For detailed instructions, see the EX-series Speedlite's instruction
manual. This camera is a Type-A camera that can use all the features of
EX-series Speedlites.
