Canon EOS 60D - Manual (Page 148)

Basically operates like a built-in flash for easy operation.
When an EX-series Speedlite (sold separately) is attached to the
camera, almost all the autoflash control is done by the camera. In other
words, it is like a high-output flash attached externally in place of the
built-in flash.
For detailed instructions, see the EX-series Speedlite’s instruction
manual. This camera is a Type-A camera that can use all the features
of EX-series Speedlites.
With an EZ/E/EG/ML/TL-series Speedlite set in TTL or A-TTL
autoflash mode, the flash can be fired at full output only.
Set the camera’s shooting mode to (manual exposure) or
(aperture-priority AE) and adjust the aperture setting before
shooting.
When using a Speedlite which has manual flash mode, shoot in the
manual flash mode.

With an EX-series Speedlite not compatible with flash function settings
(p.135), only [1 exp. comp] and [E-TTL II meter.] can be set for
[External flash func. setting]. (Certain EX-series Speedlites also
enable [Shutter sync.] to be set.)
If the flash metering mode is set to TTL autoflash with the Speedlite’s
Custom Function, the flash will fire at full output only.
