When an EX-series Speedlite is attached to the camera, almost all the autoflash control is done by the camera. In other words, it is like a highoutput 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.
