Using the Flash (continued)
• When shooting with a high ISO sensitivity and using the built-in flash, there is
more of a chance of overexposure the closer you are to the subject.
• When shooting with [Slow Synchro] set to [On], we recommend the use of a
tripod to prevent camera shake.
• Some settings are not available with certain Shooting modes. Please refer to
Functions Available in Each Shooting Mode (p. 204).
• The flash fires twice. A pre-flash will fire and will be followed by the main flash.
The pre-flash is used by the camera to obtain the subject's exposure data so that
the main flash can be set to the optimal intensity for the shot.
• The fastest shutter speed for flash synchronization is 1/250 second. The camera
automatically resets the shutter speed to 1/250 second if a faster speed is selected.
• The built-in flash may take up to approximately 10 seconds to charge in some
cases. Actual times will vary according to usage and the battery charge.
• The flash fires with automatic adjustments when [Flash Adjust] is set to [Auto] in
the [ (Rec.)] menu. When shooting in
[Manual], the flash fires fully or with the manually set adjustments.
• The flash exposure and the Flash Output can be changed (p. 100).
• The flash setting is saved when the camera is turned off in the ,
shooting modes.
• When shooting with the flash, light may reflect off dust purticles or insects in the
air and appear as white dots or white asterisks on the image. This occurs more
frequently in the following conditions:
– When shooting at the wide-angle end.
– When shooting with a high aperture value in the aperture-priority AE mode.
This is a phenomenon that occurs with digital cameras and does not constitute a
malfunction.
