Other external fl ash units
Connect a sync cord to the hot shoe or the external fl ash terminal. When not using the
external fl ash terminal, make sure to attach the cap.
Note the following when using a third-party fl ash unit mounted on the camera hot shoe:
• Using obsolete fl ash units that apply currents of more than about 250 V to the X-contact
will damage the camera.
• Connecting fl ash units with signal contacts that do not conform to Olympus specifi cations
may damage the camera.
• Set the Shooting mode to M, set the shutter speed to a value no higher than fl ash
synchronous speed, and set ISO sensitivity to a setting other than [AUTO].
• Flash control can only be performed by manually setting the fl ash to the ISO sensitivity
and aperture values selected with the camera. Flash brightness can be adjusted by
adjusting either ISO sensitivity or aperture.
• Use a fl ash with an angle of illumination suited to the lens. Angle of illumination is usually
expressed using 35-mm format equivalent focal lengths.
