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

D

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.
