Nikon 2191 manual Focusing, zooming, and depth of field, Setting the aperture

Focusing, zooming, and depth of field

Before focusing, rotate the zoom ring 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 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 and the subject may appear in focus at a position that is closer than infinity.

•For more information, see page 144.

•When the zoom lock is set to LOCK position at the focal length of 28mm, 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 28mm to 300mm 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.
