Using the Built-in Flash 75

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)).

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.

1Lens Compatibility with the Built-in Flash (p.179)

•The built-in flash fully discharges for lenses without a function to set the lens aperture ring to s(Auto).

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).
