What focus mode and area mode does Nikon d750 usually set?

Nikon D750 provides AF autofocus and M manual autofocus. AF autofocus can be divided into AF-S single servo autofocus, AF-C continuous servo autofocus and AF-A automatic servo autofocus. Choosing the right focusing method can help us to complete the focusing work smoothly. The following explains how to use them respectively.

AF-S single-shot servo autofocus stops autofocus after focusing (focusing succeeds when the shutter is pressed halfway). At this time, when the shutter is pressed halfway, the composition can be readjusted. This autofocus mode is usually used to shoot still or small moving objects.

After selecting AF-C continuous servo autofocus mode, when the photographer presses the shutter half to focus, keep the shutter half pressed, and the camera will automatically switch the focus to keep the moving object in accurate focus. If the position or state of the subject changes greatly during this process, the camera will automatically make adjustments.

AF-A automatic servo autofocus mode is suitable for situations where it is impossible to determine whether the object is still or moving. At this time, the camera will automatically select single servo autofocus mode (AF-S) or continuous servo autofocus mode (AF-C) according to whether the subject is moving.

AF-A automatic servo autofocus mode is suitable for shooting insects, birds, children and other objects whose movements cannot be accurately predicted.

In some cases, it is difficult to shoot directly with the autofocus function. Set the focus mode to single servo autofocus, move the autofocus point to another object with the same distance as the subject to be focused, then re-compose the image and press the shutter button half-way.
