• Do not turn the camera off or remove the lens from the camera while

vibration reduction is operating. Failure to observe this note could

result in the lens sounding and feeling as if an internal component is

Jp

loose or broken when it is shaken. This is not a malfunction. Turn the

camera on again to correct this.

En

• With cameras featuring a built-in flash, vibration reduction does not

function while the built-in flash is charging.

De

• When using a tripod, set the vibration reduction ON/OFF switch to

ON to reduce the effect of camera shake. Nikon recommends the

Fr

switch be set to ON when using the camera on an unsecured tripod

head or with a monopod. But when camera shake is very slight, the

Es

vibration reduction function may conversely increase the effect of

camera shake by the movement of the system. In such a case, set the

Se

vibration reduction ON/OFF switch to OFF.

Setting the aperture

Use the camera to adjust the aperture setting.

Focusing, zooming, and depth of field

Before focusing, rotate the zoom ring to adjust the focal length until

It

the desired composition is framed. If your camera has a depth-of-field

preview (stop-down) button or lever, depth of field can be previewed

Ck

through the camera viewfinder.

This lens is equipped with the Internal Focusing (IF) system. As the

Ch

shooting distance decreases, the focal length also decreases.

• The distance scale does not indicate the precise distance between the

Kr

subject and the camera. Values are approximate and should be used

only as a general guide. When shooting distant landscapes, depth of

field may influence operation and the subject may appear in focus at

a position that is closer than infinity.
