DUsing an External Speedlite
Canon Speedlites Other Than the EX-series
With an EZ/E/EG/ML/TL-series Speedlite set to A-TTL or 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 shooting.
When using a Speedlite that has manual flash mode, shoot in the manual flash mode.
Using Non-Canon Flash Units
Sync Speed
The camera can synchronize with non-Canon compact flash units at 1/250 sec. and slower speeds. With large studio flash units, be sure to test the flash synchronization before shooting with the sync speed set within approx. 1/60 sec. to 1/30 sec., since the flash duration of such units is longer than that of compact flash units and vary depending on the models.
Cautions for Live View Shooting
If you use a non-Canon flash unit with Live View shooting, set [A2: Silent LV shoot.] to [Disable] (p.231). The flash will not fire if it is set to [Mode 1] or [Mode 2].
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.
Do not attach a high-voltage flash unit on the camera’s hot shoe. It may not fire.
