D Using the Built-in Flash
y Flash Exposure CompensationK
Set flash exposure compensation if the flash exposure of the subject
does not come out as desired. You can set the exposure compensation
up to ±2 stops in 1/3-stop increments.
 When you press the shutter button halfway, the <y> icon will
appear in the viewfinder.
After taking the picture, cancel the flash exposure

compensation by setting it back to 0.
If [z2: Auto Lighting Optimizer] (p.136) is set to any setting other

than [Disable], the image may still look bright even if a decreased flash
exposure compensation is set.
If flash exposure compensation is set with an external Speedlite (sold

separately, p.171), you cannot set the flash exposure compensation with the
camera (Quick Control or External flash function settings). If it is set with both
the camera and Speedlite, the Speedlite's setting overrides the camera's.
