Manual Focus with the electric rangefinder

Make sure to check the focus indicator (the electric rangefinder) until the green dot lights up continuously in the viewfinder.

For Nikon D7000: If the lens has a maximum aperture of f/5.6 or faster, the viewfinder focus indicator can be used to confirm whether the subject in the selected focus point is in focus (the focus point can be selected from any of the 39 focus points). After positioning the subject in the selected focus point, press the shutter-release button halfway and rotate the lens focus ring until the in-focus indicator (green dot) is displayed.
