Sony HVL-F42AM Operating Instructions Manual page 24

Built-in wide panel (16 mm zoom
angle)
Pulling out the built-in wide panel expands flash coverage to a focal length of 16
mm.
Pull out the wide panel.
• The ZOOM lamp [WIDE] is lit up the display panel.
• When storing the wide panel, insert it in completely.
• Do not pull out the wide panel forcibly. This may damage the wide panel.
• When photographing a flat subject from the front at a focal length of about 16
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 16 mm, the periphery of
the screen may darken.
• The focal length corresponds to the equivalent 35mm-format focal length.
• This flash unit does not support the angle of view of a 16 mm F2.8 Fisheye lens.
