: Center-weighted average
The metering across the screen is averaged, with the center of the screen weighted
more heavily.
Caution
With (evaluative metering), holding down the shutter button halfway when
shooting with [One-Shot AF] locks the exposure value (AE lock). With (partial
metering), (spot metering), or (center-weighted average), exposure is set at
the moment the picture is taken (without locking the exposure value when the
shutter button is pressed halfway).
