66Using the Built-in Flash

3 BasicOperations

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.238)

• When using the built-in flash, remove the lens hood before shooting. Vignetting may occur depending on the lens being used and the capture conditions. Refer to “Lens and Built-in Flash” (p.257) 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.235).
