the button in the center of that switch (seen in Figure 5.11) and rotate the sub-command dial. The selected AF mode will appear in the viewfinder briefly as you make your selec- tion, and on top of the camera in the monochrome LCD panel. It will also be shown on the back-panel LCD when the shooting settings screen is active. (See Figure 5.12.)

Single-Point AF

In this mode, you always select the focus point manually, using the multi selector but- ton (which, helpfully, will respond to your thumb-presses not only in the left/right and up/down directions, but diagonally, as well). The D7000 evaluates focus based solely on the point you select, making this a good choice for subjects that don’t move much. As I mentioned earlier, you can use CSM #a6 to choose whether the selected focus point resides in an 11-point widely spaced distribution, or within the full 39-point array. In either Single-point AF or Dynamic AF, if you want to lock the focus point you’ve selected for a series of shots, rotate the focus selector lock lever back to the L position. You can also temporarily lock the focus point by partially depressing the shutter release, or pressing the AE-L/AF-L button (unless you’ve redefined this behavior to some other controls in the Custom Settings menu).
