Basic Operations
Using the Built-in Flash
Use the following procedures to take a picture 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 4 m. Exposure will not be
properly controlled and vignetting 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.149))
Using the Built-in Flash
B
Auto discharge
Camera automatically determines surrounding light
and built-in flash pops up and discharges
automatically when necessary. (Flash does not
discharge even if it is popped up when not
necessary.)
b
Manual discharge
Discharges flash manually. Flash discharges when
popped up, does not discharge when retracted.
C
Auto flash+Redeye
reduct
Light a red-eye reduction light before automatic
flash.
D
Manl flash+Redeye
reduct
Discharges flash manually. Light a red-eye
reduction light before manual flash.
•In a Flash OFF mode, flash does not discharge even if settings are changed.
The set Flash mode is retained.
Manual discharge mode (Flash ON) is used regardless of flash mode settings
if the K button is pressed to pop up the flash manually.
Compatibility of built-in flash and lens
Vignetting (surrounding portions are blackened due to a lack of light)
may occur depending on the lens being used and the capture
conditions. We recommend taking a test shot to confirm this.
