Shooting Functions 114 Linking AE to AF Point during Multi-Segment Metering In [6. Link AE to AF Point] of the [A Custom Setting 1] menu (p.85), you can link the exposure and AF point in the focusing area during multi-segment metering. 1 Off Exposure is set separately from AF point. (default setting) 2 On Exposure is set in accordance with AF point. Using the Center-Weighted Metering 4 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 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.116) when the subject is extremely small and the proper exposure is difficult to obtain. Setting the Meter Operating Time You can set the exposure metering time to [10sec.] (default setting), [3sec.] or [30sec.] in [4. Meter Operating Time] in the [A Custom Setting 1] menu (p.85).
