Using EOS-Dedicated, External Speedlites

¡
When using an external Speedlite, retract the built-in flash before
mounting the external Speedlite.
¡
If the EX-series Speedlite’s firing mode is set to TTL autoflash with the
Custom Function, the Speedlite will not fire.
¡
If autofocus cannot be achieved, the external, EOS-dedicated
Speedlite’s AF-assist beam (if the Speedlite has an AF-assist beam) will
be emitted automatically (except in <
3
> <
5
> <
7
> modes).
¡
The EOS 20D is a Type-A camera that can use all the features of EX-
series Speedlites.
Using Non-Canon Flash Units
The EOS 20D can synchronize with compact, non-Canon flash units at
1/250 sec. or slower shutter speeds. With large studio flash, the sync
speed is 1/125 sec. or slower. Be sure to test the flash unit beforehand
to make sure it synchronizes properly with the camera.
¡
The camera’s PC terminal is provided for flash units having a sync
cord. The PC terminal is threaded to prevent inadvertent disconnection.
¡
The camera’s PC terminal has no polarity so you can connect any
sync cord regardless of its polarity.

If the camera is used with a flash unit or flash accessory dedicated to
another camera brand, the camera may not operate properly and
malfunction may result.
¡
Also, do not connect to the camera’s PC terminal any flash unit requiring
250 V or more.
¡
Do not attach a high-voltage flash unit on the camera’s hot shoe. It might
not work.
A Speedlite attached to the camera’s hot shoe and a flash unit connected to
the PC terminal can be used at the same time.
