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
polarity is opposite from the camera’s PC terminal.
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.
