160Matrix Metering systemAn advanced exposure metering system using a multi-segmentsensor and computer. Available in the F5 and other Nikon SLRcameras.3D Color Matrix Metering: With Multi-Meter Finder DP-30and D-type Nikkor lenses, 3D Color Matrix Metering is auto-matically activated with the F5. With the classic techniques ofevaluating for 18% reflectance, factors such as brightnessand contrast are primarily used to determine exposure. Inaddition, it is essential to evaluate each scene’s estheticfactors such as color to get the best exposure. The shadowsof a building, cool with blue. A panoramic landscape with abright blue sky. Or a winter scene covered with pristine whitesnow. The F5’s 3D Color Matrix Meter evaluates not onlyeach scene’s brightness and contrast but, using a specialRed-Green-Blue (RGB) sensor, it also evaluates the scene’scolors. Then its powerful microcomputer and databasetogether guide it to unequaled exposure control.Monitor Pre-flash(es)When performing Automatic Balanced Fill-Flash with TTL MultiSensor, the Speedlight fires a series of scarcely visible pre-flashes to enable the camera’s computer to pre-analyze thescene. The TTL Multi Sensor inside the camera body reads theamount of reflected light, then the camera’s microcomputerdetermines the area of the TTL sensor to be used for flashoutput control and adjusts the flash output level. The MonitorPre-flashes are visible but not recognizable.Rear-Curtain SyncFlash fires an instant before the second (rear) curtain of the focalplane shutter begins to move. When slow shutter speeds areused, this feature can create a blur effect from the ambient light,i.e., a flowing-light patterns following a moving subject withsubject movement frozen at the end of the light flow. (See“Front-Curtain Sync”.)Release-Priority for autofocusShutter can be released anytime (i.e., even when subject is notin focus). Helps you avoid missed opportunities when you arenot concerned with absolute focusing precision.With the F5 camera body, Release-Priority is given toContinuous Servo AF mode while Focus-Priority is given toSingle Servo AF. Using Custom Setting, however, you canchange the priority to Focus-Priority Continuous Servo AF orRelease-Priority Single Servo AF.P400 (E) 02.12.27 6:42 PM Page 160
