■ Speaker. Your D7000 emits sounds, such as your movie audio track, through this
device.
■ AE-L/AF-L (autoexposure/autofocus) lock. This button can be programmed
by you to provide a variety of autoexposure/autofocus locking functions, which
I’ll explain in Chapter 9. By default, it locks the exposure or focus that the camera
sets when you partially depress the shutter button. The exposure lock indication
(AE-L icon) appears in the viewfinder. If you want to recalculate exposure or aut-
ofocus with the shutter button still partially depressed, press the button again. The
exposure/autofocus will be unlocked when you release the shutter button or take
the picture. To retain the exposure/autofocus lock for subsequent photos, keep the
button pressed while shooting.
■ Main command dial. This is the main control dial of the D7000, used to set or
adjust most functions, such as shutter speed, bracketing sequence, white balance,
ISO, and so forth, either alone or when another button is depressed simultaneously.
It is often used in conjunction with the sub-command dial on the front of the cam-
era when pairs of settings can be made, such as image formats (main command dial:
image format; sub-command dial: resolution); exposure (main: shutter speed; sub:
aperture); flash (main: flash mode; sub: flash compensation); or white balance
(main: WB preset; sub: fine-tune WB). You can swap functions of the main and
sub-command dials, reverse the rotation direction, choose whether the aperture ring
on the lens or the sub-command dial will be used to set the f/stop, and activate the
main command dials to navigate menus and images. You’ll learn about these
Custom Settings menu options (CSM #f6) in Chapter 9.
