Using the Built-in Flash
3
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.

Lens Compatibility with the Built-in Flash (p.172)
• When using the built-in flash, remove the lens hood before shooting.
• The built-in flash fully discharges for lenses without a function to set aperture lens ring to s (Auto).
For details on the built-in flash and instructions on how to take pictures with the
external flash, refer to the “Using the Flash” (p.167).

Using Red-eye Reduction Flash
“Red-eye” is the phenomenon where eyes look reddish in photographs taken in dark environments with a flash. This is caused by the reflection of the electronic flash in the retina of the eye. Redeye occurs because pupils are dilated in dark environments.
This phenomenon cannot be averted but the following measures can be used to combat it.
• Brighten the surroundings when shooting.
• Set to wide angle and move closer to the subject if a zoom lens is in use.
• Use a flash that supports red-eye reduction.
• Position the flash as far away from the camera as possible when using an external flash.
The red-eye reduction function on this camera reduces red-eye by discharging the flash twice. With the red-eye reduction function, the pre-flash is discharged just before the shutter is released. This reduces pupil dilation. The main flash is then discharged while the pupils are smaller, reducing the red-eye effect.
To use the red-eye reduction function, set D in B mode, or F or
H in other modes.
