Using the Built-in Flash

72
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)).

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.
1 Lens Compatibility with the Built-in Flash (p.172)
