Dynamic Area AF is one of three Nikon AF Area Modes. With Dynamic Area AF, you can select from several focusing options: 9-, 21- or all 51-point AF. Select a Single AF point and the areas surrounding it serve as backup—a significant advantage when shooting moving subjects. Select the 9-point option when you want to focus on erratically moving subjects with greater accuracy. When dealing with insufficient contrast for fast focus detection, choosing 21 or 51 points makes detection easier. The 51-point option also allows for 3D Focus Tracking, which uses color information from the RGB metering sensor to automatically follow moving subjects across the AF points.nikongrossary
