D Flash Photography

EOS-dedicated, EX-series Speedlites
An EX-series Speedlite (sold separately) makes flash photography as
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
menu, see pages 199-204.
Shoe-mount Speedlites
FE lock
This enables you to obtain a proper flash exposure for a specific part
of the subject. Aim the viewfinder center over the subject, then press
the camera's <B> 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.
Press the camera's <Q> button, then turn the <5> dial while
looking at the viewfinder or top LCD panel.
If [z2: Auto Lighting Optimizer] (p.152) is not set to [Disable], the image
may still look bright even if a darker flash exposure compensation amount
was set.
When it is difficult to achieve focus with autofocus, the EOS-dedicated,
external Speedlite may automatically emit the AF-assist beam.
