[] Adjusting Viewfinder Focus
If you are unable to focus the viewfinder as described above, select single-servo autofocus
(AF-S; _ 42), single-point AF ([-]; _ 45), and the center focus point (_ 46), and then frame
a high-contrast subject in the center focus point and press the shutter-release button
halfway to focus the camera. With the camera in focus, use the diopter adjustment control
to bring the subject into clear focus in the viewfinder. If necessary, viewfinder focus can be
further adjusted using optional corrective lenses (_ 166).
