Basic Operations

Using the Built-in Flash
Use the following procedures to take pictures in low light or backlit
conditions and when you want to use the built-in flash.
The built-in flash is optimum for a subject at a distance from 0.7 m to 5 m.
Exposure will not be properly controlled and vignetting (darkening of the
corners of the image due to a lack of light) may occur when used at a
distance closer than 0.7 m (this distance varies slightly depending on the
lens being used and the set sensitivity (p.178)).
For details on the built-in flash and instructions on how to take pictures with an
external flash, refer to the “Using the Flash” (p.173).
Setting the Flash Mode
Flash Mode Function
C
Auto Flash
Discharge
The camera automatically measures the ambient light
and determines whether to use the flash. The flash
pops up and discharges automatically when necessary,
such as when using a shutter speed which is likely to
cause camera shake or in backlit conditions (except
when in s (Landscape), \ (Moving Object) or l
(Night Snap) in H (Scene) mode). The flash may pop
up but may not discharge if the camera determines that
the flash is not necessary.
b
Manual Flash
Discharge
Discharges the flash manually. Discharges when the
flash is popped up, does not discharge when retracted.
i
Auto Flash+Red-
eye Reduction
Discharges a pre-flash for red-eye reduction before the
automatic flash.
Compatibility of built-in flash and lens
Vignetting may occur depending on the lens being used and the
capture conditions. We recommend taking a test shot to check the
compatibility.
1 Lens Compatibility with the Built-in Flash (p.179)
When using the built-in flash, remove the lens hood before shooting.
The built-in flash fully discharges for lenses without a function to set the
lens aperture ring to s (Auto).
