Wireless Flash Control Range
The illustration is intended as a guide only. The fl ash control range varies with the type
of fl ash mounted on the camera and the conditions in the surrounding area.
Flash Control Range for Camera-Mounted FL-LM3 Flash Units
• We recommend that each group contain no more than 3 fl ash units.
• Wireless fl ash photography is not available in anti-shock mode or in rear-curtain slow sync
6
mode when a shutter speed slower than 4 s is selected.
• Start wait times longer than 4 s cannot be selected in anti-shock and silent modes.
• Flash control signals may interfere with exposure if subject is too close to the camera.
This can be mitigated by reducing the brightness of the camera fl ash, for example by
using a diffuser.
Other external fl ash units
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.
• Select mode M, choose a shutter speed no faster than the fl ash sync speed, and set
[K ISO] to [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.
