■ Focusing, zooming, and depth of field
Before focusing, rotate the zoom ring 5 to adjust the
focal length until 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
through the camera viewfinder.
• This lens is equipped with the Nikon Internal
Focusing (IF) system. As the shooting distance
decreases, the focal length also decreases.
• The distance scale does not indicate the precise
distance between the 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 so that the camera may
focus at a position that is closer than infinity.
• When the zoom lock switch g is set to LOCK
position at the focal length of 18mm, the zoom ring is
locked. When carrying the camera, lock the zoom ring
to prevent the lens from extending due to its own
weight.
■ Setting the aperture
Use the camera to adjust the aperture setting.
■ Variable maximum apertures
Zooming the lens from 18mm to 200mm decreases the
maximum aperture by 1
1
/ 3 stop.
However, there is no need to adjust the aperture
setting to achieve correct exposures because the
camera automatically compensates for this variable.
■ Focusing (Fig. A)

chart below:
For more information on camera focus modes, refer to
your camera’s User’s Manual.
