OTHER RECORDING FUNCTIONS
3.
Turn on the external flash unit, and set it up
for the camera's aperture (F) value (page 84)
and sensitivity (ISO 50 equivalent) value.
• Depending on shooting conditions, proper exposure
may not be obtained even if you properly set the auto
aperture (F) value and ISO sensitivity of the flash
unit to match those of the camera. If this happens,
adjust the auto aperture (F) value, ISO sensitivity, or
other settings of the flash unit. Also try adjusting the
aperture of the camera.
IMPORTANT!
• The external flash connected to the external flash
sync terminal always fires. To record an image
without using external flash, disconnect the sync
cable from the terminal or turn off external flash unit
power.
• After recording an image, check it on the monitor
screen. If it is not what you expected, use the
controls on the external flash unit to adjust flash
intensity, and adjust the aperture and ISO sensitivity
settings on the camera. Note that you cannot control
external flash unit intensity using camera settings.
• Close up images often tend to be overexposed. If
you are having overexposure problems, try adjusting
the aperture and ISO sensitivity settings of the
external flash unit and the camera. You can also try
using the camera's built in flash to correct for
overexposure.
• Note that the camera's built in flash fires whenever
its Flash Mode setting is something other than
(Off).
• Camera aperture (F) values are based on the widest
optical zoom (1X). Using telephoto can cause slight
lens darkness. Adjust the aperture and ISO
sensitivity settings of the external flash unit and the
camera as required when using optical zoom.
• When using a zoom flash, a coverage angle for a
focal distance of 33mm or less for the flash unit is
recommended.
