Using Non-Canon Flash Units
The EOS D30 can synchronize with compact, non-Canon flash units at shutter speeds of 1/200
second or slower. With larger studio flash units, the flash speed is 1/60 second or slower. Be
sure to test the flash you are using beforehand, to make sure it synchronizes properly with the
We recommend you use a flash with sync cable connected to the PC contacts. The PC
terminal has a locking thread to prevent accidental disconnection. Only the X-sync terminal is
used for synchronization at 1/200 second or slower.
You can use a flash unit attached to the camera's hot shoe and another flash unit
connected to the PC terminal at the same time.
We recommend Canon EX-series Speedlites for use with this camera.
If you use the EOS D30 with a flash unit or flash accessory built for another brand
of camera, the EOS D30 may not operate properly.
Some large studio flash units have a sync
cord polarity that is the opposite of the EOS
D30’s PC terminal. Such flash units will not
work with the EOS D30 unless you change
the polarity of the sync cord. Consult the
manufacturer of the flash unit, or purchase a
commercially-available polarity conversion
cord. The camera’s PC terminal polarity is
shown in the figure on the right.
