Canon EOS60D18135ISKIT User Manual (en)

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 
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 <a> (manual exposure) or 
<f> (aperture-priority AE) and adjust the aperture setting before 
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.
