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.
