■Autofocus with manual override (M/A mode)
1 Set the focus mode switch to M/A. (Fig. D)
2 You can manually override autofocus by operating the manual focus ring while lightly depressing

the shutter release button or the AF-Start (AF-ON) button on the camera or the Focus operation
button on the lens.

3 To cancel manual override, remove your finger from the shutter release button or the AF start

button on the camera or the Focus operation button on the lens, and lightly depress the shutter
release button to return to the autofocus mode.

■To limit the range of autofocus 

(For AF cameras compatible with AF-S Nikkor lenses only)

With AF operation, if the subject is always more than 6m (19.7 ft.) away, set the focusing limit
switch to “

∞–6m” to reduce focusing time. If the subject is 6m (19.7 ft.) or closer, set it to “FULL”

(Fig. E).

Depending on the position of the Focus operation selection switch, the function of the Focus
operation button varies:

The position of the Focus operation buttons can be changed to suit your preference. For more
