AF-Area Mode Choose how the focus point for autofocus is selected. The following options are available during viewfinder photography: Option Description c Single-point AF For stationary subjects. Focus point is selected manually; camera focuses on subject in selected focus point only. For non-stationary subjects. In AF-A and AF-C focus d Dynamic-area AF modes, user selects focus point using multi selector (0 69), but camera will focus based on information from surrounding focus points if subject briefly leaves selected point. In AF-A and AF-C focus modes, user selects focus point using multi selector (0 69). If subject moves after camera has focused, camera uses 3D- f 3D-tracking (11 points) tracking to select new focus point and keep focus locked on original subject while shutterrelease button is pressed halfway. e Auto-area AF Camera automatically detects subject and selects focus point. Note that d (Dynamic-area AF) and f (3D-tracking (11 points)) AF-area modes are not available when AF-S is selected for focus mode. A 3D-Tracking (11 Points) If subject leaves the viewfinder, remove your finger from the shutterrelease button and recompose the photograph with the subject in the selected focus point. Note that when the shutter-release button is pressed halfway, the colors in the area surrounding the focus point are stored in the camera. Consequently 3D-tracking may not produce the desired results with subjects that are similar in color to the background or that occupy a very small area of the frame. More on Photography 67
