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

stop.
However, there is no need to adjust the 
aperture setting to achieve correct exposures 
because the camera automatically 
compensates for this variable.
