Other external flash units

Note the following when using a third-party flash unit mounted on the camera hot shoe:
• Using obsolete flash units that apply currents of more than about 24 V to the X-contact will
damage the camera.
• Connecting flash units with signal contacts that do not conform to Olympus specifications
may damage the camera.
• Set the Shooting mode to M, set the shutter speed to a value no higher than flash
synchronous speed, and set ISO sensitivity to a setting other than [AUTO].
• Flash control can only be performed by manually setting the flash 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 flash with an angle of illumination suited to the lens. Angle of illumination is usually
expressed using 35-mm format equivalent focal lengths.
