Prefocusing The lens can also
be
prefocused using the distance
scale engraved
in
both feet and meters on the lens
barrel. Line up the
bl
ack indicator line on top
of
the lens opposite the camera-to-subject distance
as
measured or estimated. This technique
is
useful for
candid shots
of
elusive ,subjects when time does
not permit through-the-Iens focusing.
The mark on the top deck shows the exact
position
of
the film plane. This
is
an
aid when
measuring the film-to-subject distance
in
close-
ups and macrophotography.
Viewfinder frame coverage
The ratio
of
the area seen through the 'viewfinder
to the actual area
of
the printed picture
(view-
finder frame coverage)
is
approx. 92%. I n plan-
ning a shot, you can include more than actually
appears
in
the viewfinder.
Eyepiece correction lenses
Nikon eyepiece correction lenses are availab'le for
near-sighted and far-sighted users to assist
in
sharper focusing. Refer to
