To select autofocus mode, push the focus mode button and rotate focus mode ring until it clicks into
position at A. When ring locks, lens is set for autofocus operation. Be sure camera’s focusing mode is set at
C or S. In autofocus mode, you can use either “Focus lock” or “Preset focusing” (with focusing limit switch).
For details, see the following page.
To select autofocus mode with manual priority, push the focus mode button and rotate focus mode ring
until it clicks into position at M/A. When the ring locks, lens is set for autofocus with manual-priority
operation. To focus manually, while lightly pressing the shutter release button rotate the focusing ring until
the viewfinder image appears sharp and crisp. Removing your finger from the shutter release button cancels
manual focus mode to resume autofocus. Be sure the camera’s focusing mode is set at C or S to activate
autofocus operation.
To select manual mode, push the focus mode button and rotate the focus mode ring until it clicks into position
at M. When the ring locks, lens is set for manual focus. Rotate focusing ring until the viewfinder image
appears sharp and crisp. The electronic rangefinder can be used as a focusing assist.
For manual focus with lens’ focusing mode set at M/A, first set the camera’s focusing mode to M. Next,
push the lens' focus mode button and rotate focus mode ring until it clicks into position at M/A. To focus
manually, while lightly pressing the shutter release button rotate the focusing ring until the viewfinder image
appears sharp and crisp. Removing your finger from the shutter release button cancels manual focus mode to
resume autofocus mode. It does not, however, activate autofocus operation, because the camera's focusing
mode is set at M. The electronic rangefinder can be used as a focusing assist.
For a Nikon Autofocus Camera (except the F3AF)
Only manual focusing operation is available.
Push the focus mode button and rotate the focus mode ring until it clicks into position at M. When the ring
locks, lens is set for manual focus. Rotate the focusing ring until the viewfinder image appears sharp and
crisp. The electronic rangefinder can be used as a focusing assist. To focus manually with the focus mode
ring set at M/A, the M/A mode must be set for manual before lens is attached to the camera.
For a Nikon Non-Autofocus Camera
Only manual focusing operation is available.
Push the focus mode button and rotate focus mode ring until it clicks into position at M. When the ring
locks, lens is set for manual focus. Rotate focusing ring until the viewfinder image appears sharp and crisp.
FOCUS LOCK (WITH AN F4-SERIES, F90X/N90S, F90-SERIES/N90 OR F70-
SERIES/N70 CAMERA)
When shooting a subject that is off-center or moving in Continuous Servo Autofocus mode, press this button
to lock focus. To cancel focus lock and reactivate autofocus, remove your finger from the focus lock button.
Although AF-Lock function can be set on both camera and lens, priority is given to whichever is set first.
FOCUSING LIMIT SWITCH (WITH AN F4-SERIES, F90X/N90s, F90-
SERIES/N90 OR F70-SERIES/N70 CAMERA)

pre-determined distance range for the subject(s). There are three focusing limit zones provided:
Close distance — infinity (oo) Set switch to front setting (FULL)
Close distance — 7m Set switch to middle setting (7 — 3.3m)
