EXPOSURE METERING SYSTEM The Nikon F5 has three types of exposure metering systems-- 3D Color Matrix Metering, Center-Weighted Metering and Spot Metering. q 3D Color Matrix Metering (with the Multi-Meter Finder DP-30 This system is ideal for quick operation in any exposure mode. With D- or G-type AF Nikkor lenses including AF-I or AF-S Nikkor, 3D Color Matrix Metering is automatically activated. 3D Color Matrix Metering uses various types of data: scene brightness, scene contrast, focused subject's distance (Distance Information) and color distribution of the entire frame. Data on scene brightness, contrast and color distribution are detected by the camera's 1,005-pixel Matrix Sensor, while data on the focused subject's distance is detected and relayed by your Dor G-type AF Nikkor lens. 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 F5's built-in microcomputer is able to provide correct exposure even in extremely complex lighting situations. If a non-D/G-type lens is used, Matrix Metering is performed. Although lens' Distance Information is not given, 1,005-pixel Matrix Sensor provides the correct exposure in most lighting situations. Note that Matrix Metering system can only be used with lenses having a built-in CPU (such as AF Nikkor and AI-P lenses.) 49
