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.

Lens Compatibility with the Built-in Flash (p.179)
• 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 the lens aperture ring to s (Auto).

external flash, refer to the “Using the Flash” (p.173).

Function
The camera automatically measures the ambient light and determines whether to use the flash. The flash pops up and discharges automatically when necessary, such as when using a shutter speed which is likely to cause camera shake or in backlit conditions (except when in s (Landscape), \ (Moving Object) or l
(Night Snap) in H (Scene) mode). The flash may pop up but may not discharge if the camera determines that the flash is not necessary.
Discharges the flash manually. Discharges when the flash is popped up, does not discharge when retracted.
Discharges a pre-flash for red-eye reduction before the automatic flash.

Sets to a slow shutter speed depending on the brightness. For example, when using this to shoot a portrait with the sunset in the background, both the person and the background are captured beautifully.

Discharges the flash immediately before closing the shutter curtain. Captures moving objects as if they are
leaving a trail behind. (p.176)
You can synchronize a dedicated external flash
(AF540FGZ or AF360FGZ) without using a sync cord.

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.
Red-eye 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 a red-eye effect 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 in Picture mode or H (Scene) mode, select D or F. Set to F or H in other modes.

Daylight-Sync Shooting
In daylight conditions, the flash will eliminate shadows when a portrait picture is taken with a shadow cast on a person’s face. Use of the flash in this way is called Daylight-Sync Shooting. The b (Manual
Flash Discharge) mode is used when shooting with Daylight-Sync
Shooting.
Taking pictures
1 Pop up the built-in flash manually and confirm that the flash
2 Confirm that the flash is fully charged.

• When the flash output exceeds its maximum amount, the compensation will not be effective even if the compensation value is set to the plus (+) side.
• Compensating to the minus (–) side may not affect the image if the subject is too close, the aperture value is small or sensitivity is high.
• The flash output compensation is also effective for external flash units which support P-TTL auto flash mode.
