We recommend that each group contain no more than 3 flash units.
•
Wireless flash photography is not available in anti-shock mode or in rear-curtain slow sync
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 flash, for example by
using a diffuser.
Other external flash units
Third-party flash units can be mounted on the hot shoe or connected via a sync cable.
Be sure to replace the cap on the external flash connector when it is not in use. 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 250 V to the X-contact
will damage the camera.
•
Connecting flash units with signal contacts that do not conform to our specifications may
damage the camera.
• Select mode
M , choose a shutter speed no faster than the flash sync speed, and set
[ K ISO] 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.
