Using the Built-in Flash

68
Use a flash to take pictures in low light or backlit conditions.
The built-in flash is optimum for a subject at a distance from approx. 0.7 m
to 5 m. 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 sensitivity setting
(p.244)).
• When using the built-in flash, remove the lens hood before shooting.
3
Vignetting may occur depending on the lens being used and the shooting
conditions. Refer to "Lens and Built-in Flash" (p.263) for details.
• The built-in flash always fully discharges when using a lens without an s
(Auto) position.
For details on the built-in flash and instructions on how to take pictures with an
external flash, refer to "Using the Flash" (p.241).
