Using the Built-in Flash
Use the following procedures to take pictures 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 (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 set sensitivity (p.171)).
For details on the built-in flash and instructions on how to take pictures with the
external flash, refer to the “Using the Flash” (p.167).

Red-eye Reduction
Lights a red-eye reduction light before discharging
the flash with Flash On.
G
Slow-speed Sync

portrait with the sunset in the background, both the
person and the background are captured beautifully.
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 confirm this.
