Using the Built-in Flash
Use the following procedures to take a picture in low light or backlit
conditions or when you want to manually use the built-in flash.
The built-in flash is optimum at about 0.7 m to 5 m from the subject.
Exposure will not be properly controlled and vignetting may occur when
used at a distance closer than 0.7 m (this distance varies slightly
depending on the lens being used and set sensitivity (p.132)).
Flash Mode Function
g
Auto discharge
Camera automatically determines ambient light and
built-in flash pops up. The flash pops up and
discharges automatically when necessary, such as
when using a shutter speed likely to cause camera
shake or in backlit conditions. The flash may pop up
but may not discharge if the camera determines that
the flash is not necessary.
b
Flash On
Discharges flash manually. Discharges when the
flash is popped up, does not discharge when
retracted.
i
Auto flash+Redeye
reduct Lights a red-eye reduction light before automatic
flash.
D
Flash On+Red-eye
Discharges flash manually. Lights a red-eye reduction
light before discharging the flash.
r
Wireless Mode
You can synchronize a dedicated external flash
(AF540FGZ or AF360FGZ) without using a sync cord.
Compatibility of built-in flash and lens
Vignetting (darkening of the corners of the image due to a lack of
light) may occur depending on the lens being used and the capture
conditions. We recommend taking a test shot to confirm this.
