Canon EOS D30 - Manual (Page 100)

Using Non-Canon Flash Units
Sync Speed
The EOS D30 can synchronize with compact, non-Canon flash units at shutter speeds of 1/200
seoond 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 synohronizes properly with the
oamera.
PC Terminal
We recommend you use a flash with syno cable connected to the PC contacts. The PC
terminal has a locking thread to prevent aooidental disconnection. Cniy the X-sync terminal Is
used for synchronization at 1/200 second or slower.
O
If you use the ECS D30 with a flash unit or flash accessory built for another brand
of camera, the ECS D30 may not operate properly.
Some large studio flash units have a sync
cord polarity that is the opposite of the ECS
D30’s PC terminal. Such flash units will not
work with the ECS D30 unless you change
the polarity of the syno oord. 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.
You can use a flash unit attached to the camera's hot shoe and another flash unit
conneoted to the PC terminal at the same time.
We recommend Canon EX-serles Speedlites for use with this oamera.
