Wide panel (17 mm zoom angle)
Attaching the wide panel expands flash coverage to a focal length of 17
mm.
Attach the supplied wide panel to the flashtube.
• Push the wide panel onto the flashtube until it clicks into place.
• If removing the wide panel is difficult, pull one side off first.
• When using the wide panel, only set the zoom coverage to 24 mm.
• When photographing a flat subject from the front at a focal length of
about 17 mm, the periphery of the screen may darken slightly because
the focal distances at the center and periphery of the screen are different.
• When using a wide-angle lens with a focal length below 17 mm, the
periphery of the screen may darken.
• When using the wide panel, press the high-speed-sync button to keep
the high-speed-sync lamp off.
• See the following table for the flash range when using the wide panel.
