PARTIAL METERING
Use this mode, for stage photography, or when
there is a big difference in brightness between the
main subject and the background
• The partial metering mode can be used
regardless of the camera’s mode, except when
the main switch is set to the green mark posi­
tion (□)
• The partial metering area is approximately
6 5% of the picture area

AE lock
The original exposure value remains locked as
long as the shutter button is pressed halfway,
so even if you recompose the picture, correct
exposure on the main subject will not be
affected by changes in lighting conditions.
