Flash in Full Auto Mode
With the 420EX attached to a Type-A camera set to <D> (Full Auto) or
<P> (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). E-TTL autoflash thereby sets the flash exposure
automatically.
