Flash In Full Auto Mode - Canon Speedlite 420EX Instruction Manual

Flash in Full Auto Mode

With the 420EX attached to a Type-B camera set to < > (Program AE),
flash photography will be fully automatic and as easy as normal AE
photography without flash. The camera sets the shutter speed and aperture
automatically to suit the lighting situation, whether it is dark or daylight (fill
flash). TTL autoflash thereby sets the flash exposure automatically.
