Notes About Metering
When digital zoom is in effect, Center-weighted or spot metering (where the center of
the frame is metered) is selected depending on the zoom ratio.
This function may not be available to use in combination with other functions (A68).
C
Display on the Shooting Screen
When Center-weighted is selected, the metering range guide (A4) is displayed (except
when digital zoom is used).
Using the Menu
The Shooting Menu (A, B, C, or D Mode)
The camera uses a wide area of the screen for metering.
Recommended for typical shooting.
The camera meters the entire frame but assigns greatest
weight to the subject in the center of the frame. The classic
metering for portraits; it preserves background details while
letting lighting conditions in the center of the frame
determine exposure.
Can be used with focus lock (A65) to set focus and exposure
for off-center subjects.
