Using Flash
Supported different flash units
When selecting an external flash, use products which meet the following
basic requirements:
(1) When using the external flash, it must be possible to adjust the exposure
on the external flash unit.
To use the external flash in Auto-Flash mode, it must also be possible to
match the flash settings to the F stop and ISO settings on the camera.
(2) Even if the auto F stop and ISO settings on the external flash are matched
to the camera settings, the correct exposure may still not be obtained in
some photography situations. If this occurs, offset the auto F stop or ISO
setting on the external flash unit, or calculate the distance and use flash
in Manual mode. Note, however, that the auto F stop and ISO settings can
only be adjusted by 1 step or more, and exposure compensation is not
possible. (The exposure compensation settings on the camera do not
apply to external flash photography.)
(3) The flash must cover the field of view for the equivalent of a 40 mm
lens or larger lens in 35 mm photography. However, in close-up pho-
tography with the lens zoomed out to the wide-angle setting, the
bottom of the image may be eclipsed. For the best results, you
should use a wide-angle adapter fitted on the flash to give a wider
flash coverage.
(4) Use a flash unit with a full-intensity flash duration of 1/200 sec. or less.
When units such as ring flashes that have a long flash duration are used,
some the light emitted does not contribute to the exposure.
(5) Do not use flash units other than the FL-40 that feature additional com-
munications functions, and do not use the accessories provided with
such flash units. Such equipment, if used, could not only fail to function
normally, but may also cause damage to the camera's circuitry.
