A 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” (

Focusing 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.
