Using the Built-in Flash
Use the built-in flash when you want to take pictures in low light or backlit
conditions.
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 set sensitivity. (p.165))
For details on the built-in flash and instructions on how to take pictures with an
external flash, refer to “Using the Flash” (p.161).
