•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.
