Spot metering
r
This is for metering a specific spot of the subject or
scene. Spot metering covers approx. 1.8% of the
viewfinder area at the center. The spot metering
circle will be displayed in the viewfinder.
Center-weighted average metering
e
The metering is weighted at the center and then
averaged for the entire scene.
With q (Evaluative metering), the exposure setting will be locked when
you press the shutter button halfway and focus is achieved. In the w
(Partial metering), r (Spot metering), and e (Center-weighted
average metering) modes, the exposure is set at the moment the photo
is taken. (Pressing the shutter button halfway does not lock the
exposure.)
When <r> (Spot metering) is set, you can display <z> in the
viewfinder and on the LCD panel (p.441).
