137 Linking AF Point and AE During Multi-Segmented Metering In [Link AF Point and AE] (p.106) of the [A Custom Setting] menu, you can link the exposure and AF point in the focusing area during multi-segment metering. The default setting is [Off]. 1 Off Exposure is set separately from AF point. 2 On Exposure is set in accordance with AF point. Function Reference Using the Center-Weighted Metering Metering is weighted at the center of the screen. Use this metering when you want to compensate the exposure by experience, instead of leaving it to the 5 camera. The illustration shows that sensitivity increases as the pattern height increases (center). This mode does not automatically compensate for backlit scenes. Using the Spot Metering With spot metering, brightness is measured only within a limited area at the center of the screen as shown in the illustration. You can use this in combination with the AE lock (p.148) when the subject is extremely small and proper exposure is difficult to obtain. Setting the Meter Operating Time Sets the exposure metering time in [Meter Operating Time] in the [A Custom Setting] menu (p.106). The default setting is [10 sec]. 1 10 sec Sets exposure metering timer to 10 seconds. 2 3 sec Sets exposure metering timer to 3 seconds. 3 30 sec Sets exposure metering timer to 30 seconds.
