EXPOSURE METERING SYSTEM

SELECTING METERING SYSTEM

IWl Matrix Metering

This system is ideal for quick operation in any exposure mode (pages 46 to 60). With D-type AF Nikkor lenses (including AF-S/ AF-I Nikkor lenses), 3D Matrix Metering is automatically activated. 3D Matrix Metering uses three types of data: (1) scene brightness, (2) scene contrast and (3) focused subject's distance (Distance Information) . Data on scene brightness and contrast are detected by the camera'seight-segment Advanced Matrix Sensor, while data on the focused subject's distance is detected and relayed by the D-type AF Nikkor lens in use. In addition, the information sent by the camera's

autofocus system indicating whether the main subject is centered is also considered in the computation. By analyzing these data, the N70'sbuilt-in microcomputer is able to provide correct exposure even in extremely complex lighting situations. If a non-D-type lens is used, Advanc~d Matrix Metering is performed. Although lens'Distance Information is not given, eight-segment Advanced Matrix Sensor provides the correct exposure in most lighting situations.

Note that Matrix Metering system can be used only with lenses that have a built-in CPU (such as AF Nikkor and AI-P lenses.)
