FOREWORD-----------------
Featuring internal focusing (IF), the Medical-Nikkor
120mm f/4 I F
is
a close-up
lens
providing continuously
variable reproduction ratios from 1/11 X down to 1 X
and, with the attachment
of
a
single
2X
close-up attach-
ment lens, from
O.8X
to
2X.
Because focusing
is
done
internally, there
is
no
extension
in
the
lens
barrel, making
the
lens
extremely well-balanced and convenient to
use.
Exposure with the built-in ringlight
is
totally automatic.
Once the ASA/ISO ring
is
set for the film speed
in
use,
the flash output
is
automatically determined. Then,
using a "guide number system," the diaphragm and
focusing ring are coupled,
so
that the appropriate
aperture for correct exposure
is
set
as
you focus. To let
you know when the flash
is
recycled and ready to fire,
an
LED
ready-light
is
built into the top
of
the
lens
barrel.
In
addition, automatic imprinting
of
the reproduction
ratio
in
use
is
possible
via
an
ingenious system.
Using
a
green
LED
and a miniature optical system inside the
lens
barrel, the ratio
is
projected through the lens and
appears
in
the camera's viewfinder at the lower right-hand
corner
of
the frame. Then, at the instant
of
exposure, the
ratio
is
imprinted on the film.
Finally, this
lens
offers a choice
of
AC
or
DC
power
units for use indoors or out.
Although this complete close-up system
is
called a
"Medical-Nikkor" lens, it
has
many other applications,
including dental, scientific, industrial, and nature
photography.
