Introduction of other key functions of Nikon camera;

AE-L/AF-L key: This is automatic exposure lock and autofocus lock. When the button is pressed, both will be locked at the same time, and can be locked once through the menu.

Exposure Compensation: Among all keys, "Exposure Compensation" is only used after the shutter key. This button can adjust the exposure as needed and is suitable for most shooting modes. For example, the aperture priority mode is used now, but the environment is too bright, resulting in a high shutter value judged by the camera and a dark picture. At this time, as long as the exposure compensation is rotated and moved to "+"1/3-2/3, the photo will be brighter.

Fn key: This is a custom button. Most cameras have 1-3 buttons (some even as many as 6). Users can set button functions in the menu, such as photo size/format switching, metering mode, photo style, white balance, ISO, flash, continuous shooting and so on.
