Using Non-Canon Flash Units

Sync Speed

The EOS-1 V can synchronize with compact, non-Canon flash units at 1/250 sec. or slower shutter speeds. With large studio flash, the sync speed is 1/125 sec. or slower. Be sure to test the flash to see if it synchronizes properly with the camera.

PC Terminal

The camera’s PC terminal is provided for flash units using a sync cord. The PC terminal is threaded to prevent inadvertent disconnection. Only X-sync is used for synchronization at 1/250 sec. or slower.

• A flash unit attached to the camera’s hot shoe and a flash unit connected to the PC terminal can be used at the same time.

Canon EOS-dedicated Speedlites are recommended for use with this camera.

If the camera is used with a flash unit or flash accessory dedicated to a another camera brand, the camera may not operate properly and camera malfunction may result.

There are studio flash units whose sync cord

Such flash units do not work with the EOS-1V camera unless the polarity of the sync cable is changed. 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.
