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 as with normal picture-taking without flash.

(2)When you press the shutter button completely, TTL autoflash based on the aperture set in (1) is used.

(3)The background exposure is set by the shutter speed and aperture combination.

• Flash exposure compensation can also be set with the camera.

If the multi-Speedlite system is wired with flash cords, TTL autoflash takes effect.

About automatic reduction of flash output

If an EOS-dedicated Speedlite is used to illuminate 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.

C.Fn C.Fn-14 can cancel the automatic reduction of flash output. (p.107)
