easy as normal shooting.
For detailed instructions, refer to the EX-series Speedlite's
instruction manual. This camera is a Type-A camera that can use all
the features of EX-series Speedlites.
To set the flash functions and flash Custom Functions with the camera's

Shoe-mount Speedlites
FE lock

This enables you to attain a proper flash exposure for a specific part
of the subject. Aim the viewfinder center over the subject, then press
the camera's <A> button and take the picture.
Flash exposure compensation

In the same way as normal exposure compensation, flash exposure
compensation can be set. You can set flash exposure compensation
up to ±3 stops in 1/3-stop increments.
Set it with the Quick Control screen (p.49) or [z2: External
Speedlite control]'s [Flash function settings]. When you press the
shutter button halfway, the <y> icon will appear in the viewfinder.
If [z3: Auto Lighting Optimizer] (p.125) is not set to [Disable], the image
may still look bright even if a darker flash exposure compensation amount
has been set.
When it is difficult to achieve focus with autofocus, the EOS-dedicated,
external Speedlite may automatically emit the AF-assist beam.
