OTHER RECORDING FUNCTIONS
3.Turn on the external flash unit, and set it up for the camera’s aperture (F) value (pages 93, 96) and sensitivity (ISO 80 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.
External Flash Precautions
•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.
