Using Non-Canon Flash Units

Sync Speed

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 camera.

PC Terminal

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.

●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.

● 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.
