Using Other EOS-Dedicated Speedlites
With an EOS-dedicated Speedlite other than the EX series, TTL autoflash
can be easily used like any AE mode.
The flash exposure is controlled by real-time, off-the-film flash metering
linked to the focusing point.
(1)When you press the shutter button halfway, the shutter speed and
aperture are set automatically by the camera just like normal picture-
taking without flash.

the aperture set in (1) is executed.
(3) The background exposure is set by the shutter speed and aperture

Gl «In the Basic Zone modes, flash photography is as easy as with the built-in
flash.
* Using the < DEP > mode with flash gives the same result as the <P > mode.
* Flash exposure compensation can also be set with the camera.
- If the multi-Speedlite system is wired with flash cords, TTL autoflash takes
effect.
« When it is difficult to focus, the Speedlite's built-in AF-assist light will be emitted
automatically.
* About automatic reduction of flash output
lf an EOS-dedicated Speedlite is used for a subject backlit by an overhead
light, the flash output is reduced automatically to avoid having an unnatural-
looking exposure. This is called automatic reduction of flash output.
