To focus manually, set the focus mode selector to M. (If the lens
has an A-M switch, set it to M.
If you are using an AF-I Nikkor
lens, set the focus mode ring
to M or MIA.)
There are two ways of assuring precise manual focus: with the
Electronic Rangefinder or with the viewfinder's clear matte field.

Manual focus with Electronic Rangefinder
The Electronic Rangefinder enables you to see focus status
with the viewfinder indications while you are manually focusing.
It works with most Nikon lenses (including AF Nikkor when
operated manually) which have a maximum aperture
of f/5.6 or
faster. (For a complete list
of usable lenses, see LENS
COMPATIBILITY CHART on p. 104).
1. Look through viewfinder and position focus brackets on main
subject. Then lightly press shutter release button.
