METERING

Metering determines the area of the sensor that is used for brightness evaluation:

Spot: Weights the measurement to the center 5% of the sensor, approximately.

Center: Weights the measurement to the center 25% of the sensor, approximately.

Average: Averages the entire image area of the sensor.

SPEED

The Speed setting determines how quickly the algorithm adapts to changing light.

Slow: Settings adapt in small steps. Use this setting for fewer and gradual adjustments.

Normal: Settings adapt in medium steps.

Fast: Settings adapt in large steps.

SELECTION

The Selection setting determines which values the algorithm uses. This enables you to modify the list of values

so that the algorithm selects only specific parameters. Use Free Value Selection to improve accuracy.
For example, you can modify the F stop list to include f/2.8 and f/5.6. If Free Value Selection is enabled, the

algorithm only selects F stop parameters between f/2.8 and f/5.6. This setting limits the range of focal depth.

AE LOCKS

AE Locks control which setting the camera can control. If either F stop or exposure are locked, you are in full

control of that setting and the AE feature cannot modify the setting. When both F stop and exposure are locked,

AE behaves as an indicator if the brightness fluctuates more than a stop.

AE INDICATORS

When the AE feature is able to match the sensor brightness, the overlay turns yellow. If the brightness fluctuates

more than half of a stop, the overlay turns red.
When AE is enabled, the “AE” indicator displays before the F stop and exposure parameters in the Upper Status

Row. The user-selected brightness and current measured brightness display in the histogram as gray and white

lines, respectively.

AE LIMITS

All limits, includes custom modifications made to available menu items, are taken into account when AE is

active. For example, if you modify the available list of exposure values, only those values are considered.
