Nie jest to wyjaśnione wyczerpujaco we wszystkich instrukcjach.

Normalny pomiar wielosegmentowy jest związany z wybranym punktem AF:

Evaluative: Metering is directly linked to, and concentrated on, the active Autofocus (AF) point. Light values measured at the active AF point are compared with light values measured from the metering segments surrounding the active point, and the camera's metering system attempts to provide an accurate exposure based on that comparison. This metering pattern is often effective when photographing people, but may not be quite as effective when photographing snowy landscapes depending on other elements in the scene. Note that because Evaluative Metering is linked to active AF points, focusing on a different subject may result in a very different exposure – even within the same shot.
