i Using the Built-in Flash
In Creative Zone modes, flash photography is possible at any time
regardless of the ambient light level. Whether the built-in flash or an
external EOS-dedicated Speedlite is used, the basic operation is the
same as with an AE mode.
When flash is used in a Creative Zone mode, the shutter speed (the
maximum sync speed or slower) and/or the aperture can be set as usual.
The flash output is controlled automatically to match the set aperture.
Since the 3-zone TTL autoflash system is linked to the active focusing
point, the flash exposure is weighted on the subject in focus.
• For automatic flash photography, set the Command Dial to P.
The shutter speed and aperture will be set automatically as with the
Full Auto mode. The flash exposure will be weighted on the subject
that is in focus.
• To set the flash aperture manually, set the Command Dial to Av.
In low-light conditions, a slow sync speed will be set automatically to
obtain a suitable exposure of the subject and background. For the
subject, the flash output is set automatically to match the set aperture
for a proper exposure. For the background, the sync speed is set
automatically to obtain a proper exposure.
* When a slow sync speed is set, using a tripod is recommended.
• To set the sync speed manually, set the Command Dial to Tv.
The flash aperture is set automatically to match the sync speed for a
proper exposure, and the flash output is controlled automatically to
match the flash aperture.
• If you set a shutter speed faster than 1/90 sec., the sync speed will be set automatically
to 1 /90 sec,
• To set both the flash aperture and the sync speed manually, set the
Command Dial to M.

For the background, the shutter speed and aperture can be set
manually. The flash output is then controlled automatically to match
the manually-set flash aperture for a proper exposure. *
* If A-DEP is set and flash is used, the result will be the same as using flash in the P
(Program AE) mode.
