 Using the Built-in Flash
Effective Range of Built-in Flash
[Approx. meters/feet]
Using the red-eye reduction lamp before taking a flash picture can 
reduce red eye.
 
Under the [1] tab, select [Red-eye 
On/Off
], then press <0>. Select 
[On], then press <0>.
 
For flash photography, when you 
press the shutter button halfway, the 
red-eye reduction lamp will light. Then 
when you press the shutter button 
completely, the picture will be taken.

Using Red-eye Reduction
 
For close subjects, the subject should be at least 1 meter/3.3 feet away 
when using flash.
 
Detach the lens hood and keep at least 1 meter/3.3 feet away from the subject.
 
If the lens has a hood attached or you are too close to the subject, the 
bottom of the picture might look dark due to the obstructed flash. If you 
use a telephoto lens or a fast lens and the built-in flash is still partially 
obstructed, use an EX-series Speedlite (sold separately).
 
The red-eye reduction feature is most effective when the subject looks at the red-
eye reduction lamp, when the room is well lit, or when you go closer to the subject.
 
When you press the shutter button halfway, the 
display on the viewfinder bottom will gradually turn 
off. For best results, take the picture after this display 
turns off.
 
The effectiveness of red-eye reduction varies depending on the subject.
