Multi-Spot Metering
By specifying multiple areas for spot metering, you can determine an overall exposure level
based on the average of your selected areas. Multi-spot metering is available in <
>,
< >, and < > modes.
1.
Set the metering mode to < > (spot metering).
2.
Press the < > button ( ).
Aim the spot metering circle over each area for exposure comparison,
one after another, and press the <
> button in each area.
Relative exposure levels of each spot metering area are displayed at
right in the viewfinder. These levels are averaged to obtain the current
exposure level.
While referring to the three points on the exposure level indicator, you
can set exposure compensation in this state and determine the final
exposure level for the desired result.

Spot metering with up to eight points is possible.
Stored exposure values are cleared in the following cases.
