Turn the focusing ring until the two halves of the rangefinder image coincide to form a
single, sharp image. Focusing can also be done by setting the distance scale on the lens

Focusing is always done at full aperture with Nikkor Auto lenses. This ensures a bright,
clear finder image for accurate focusing, viewing and framing. It also minimizes depth of
field so the image snaps in or out of focus distinctly.
