FOCUSING
When used with a Nikon F4-Series, F90X/N90s, F90-Series/N90 or F70-Series/N70 camera,
this lens not only lets you choose between autofocus or manual focusing, but also enables
quick switching between autofocus and manual (autofocus with manual priority) by presetting
the focus mode ring to the M/A position. With other cameras, only manual focusing is
available. See chart below to determine appropriate focus mode.

For use with a Nikon F4-Series, F90X/N90s, F90-Series/N90 or F70-Series/N70 Camera
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.
