2. Using Other EOS-Dedicated Speedlites
With an EOS-dedicated Speedlite other than the EX series, TTL autoflash
can be used as easily as normal AE modes. The flash exposure is
controlled by 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.
(2) When you press the shutter button completely, TTL autoflash metering
based on the aperture setting is used for the flash exposure.
(3) The background exposure is set by the shutter speed and aperture
combination.

Av (Aperture-priority AE) Auto (30 sec. - 1/200 sec.) Manual
M (Manual) Manual (30 sec. - 1/200 sec.) Manual
Flash exposure compensation can be set with the camera.
If the multi-flash system is wired with flash cords, TTL autoflash takes effect.

Automatic Reduction of Flash Output
If an EOS-dedicated Speedlite is used for a subject backlit by a top light, the flash
output is reduced automatically to avoid having an unnatural-looking exposure.
This is called automatic reduction of flash output.
Custom Function CF-14 can prevent the automatic reduction of flash output. See
page 118.
