Manual zoom
You can manually set the flash coverage regardless of the focal length of the lens in
use (manual zoom).
Press the ZOOM button to select the flash coverage to be
set.
• The zoom coverage is changed in the following order.
105 mm t 70 mm t 50 mm t 35 mm t 28 mm t 24 mm t A ZOOM
t 105 mm t . . .
• When zoom is set manually, [M ZOOM] is displayed above zoom coverage.
• If the flash coverage is set to less than the focal length of the lens in use, the
periphery of the screen darkens.
• The flash coverage of the manual zoom on the LCD panel is the angle of view of
the 35mm-format focal length.
Flash coverage & focal length
The larger the focal length figure of the lens on a camera, the further away a
subject can be photographed to take up the full screen; but the area that can be
covered becomes smaller. Conversely, with a smaller focal length figure,
subjects can be photographed with wider coverage. The flash coverage is the
area that the light from the flash at a set intensity or greater can cover evenly,
expressed as an angle. The flash coverage at which you can photograph is
determined by the focal length.
By having flash coverage determined in accordance with focal length, flash
coverage can be expressed as the figure for focal length.
