Sync Speed
The camera can synchronize with compact, non-Canon flash units at 1/
250 sec. or slower shutter speeds. With large studio flash, the sync
speed is 1/60 sec. or slower. Be sure to test the flash unit beforehand to
make sure it synchronizes properly with the camera.
PC Terminal
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. You can connect any sync
cord regardless of its polarity.
Cautions for Live View shooting
When using a non-Canon flash unit for Live View shooting, set the [6
Live View function settings] menu’s [Silent shoot.] to [Disable]
(p.113). The flash will not fire if it is set to [Mode 1] or [Mode 2].
Using Non-Canon Flash Units
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 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 flash unit attached to the camera’s hot shoe and a flash unit connected to
the PC terminal can both be used at the same time.
