Built-in wide panel (17 mm zoom
angle)
Pulling out the built-in wide panel expands flash coverage to a focal length
of 17 mm.
Pull out the adaptor.
• The zoom coverage display on the data panel shows "17 mm." The flash
range is also displayed.
• When storing the wide panel, insert it in completely.
• 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.
