AA Note on Wide- and Super Wide-Angle Lenses

Autofocus may not provide the desired results in situations like those shown below.

1 Objects in the background occupy more of the focus point than the main subject:

If the focus point contains both foreground and background objects, the camera may focus on the background and the subject may be out of focus.

Example: A far-off portrait subject at some distance from the background

2 The subject contains many fine details.

The camera may have difficulty focusing on subjects that lack contrast or appear smaller than objects in the background.

Example: A field of flowers

In these cases, use manual focus, or use focus lock to focus on another subject at the same distance and then recompose the photograph. For more information, see “Getting Good Results with Autofocus” (0 80).

AFocusing with AF-S DX NIKKOR 18–140mm f/3.5–5.6G ED VR Lenses

When single-servo AF (AF-S) is selected as the camera focus mode and the lens A-M switch is set to A, focus can be adjusted by keeping the shutter-release button pressed halfway after the autofocus operation is complete and manually rotating the focus ring. Do not rotate the focus ring until the autofocus operation is complete. To refocus using autofocus, press the shutter-release button halfway again.
