FOCUSING
16
Focusing isdone
at
full
aperture with Nikkor lenses fitted
with an automatic diaphragm. This technique provides
the brightest possib
Ie
images on the focusing screen for
easy focusing and composing.
It
also minimiz
es
depth
of
field
so
that
the image snaps
in
and
ou
t
of
focus
dis-
tinctly.
The Nikon Type K screen comes with the camera as
standard equipment. To focus, turn the focusing ring on
the lens until the two halves
of
the rangefinder image
coincide to form a single, crisp image; when using the
microprism ring, turn until the microprism pattern shifts
to
a sharp and crisp image. You can also focus on the
matte field
that
surrounds the rangefinder/microprism
central area.
The
lens can also be prefocused using the distance scale
engraved
in
both meters and feet on the lens barrel. Sim-
ply turn the focusing ring until the desired camera-to-
subject distance
(as
measured or estimated)
is
lined
up
with the distance scale index on the lens barrel. This
technique
is
useful for candid shots
of
elusive subjects
when time does not permit through-the-Iens focusing.
