Featuring internal focusing (IF), the Medical-Nikkor
120mm f/4 IF 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 attachment 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.
OPERATION--------------------------------------------MOUNTING THE LENS
Position the lens in the camera's bayonet mount, lining
up the black dot on the lens with the lens mounting
index on the camera. Grasp the lens barrel and twist
it counterclockwise until the lens clicks into place.
To remove, depress the lens release button on the
camera and twist the lens clockwise.
Note: To mount the 2X close·up attachment lens, refer to page 14.

-OPERATION-continued----------------------CONNECTING THE POWER SUPPLY
The Medical-Nikkor 120mm f/4 accepts either AC or
DC power units, allowing the lens to be used indoors or
out.
• DC Power Unit LD-2
This battery unit holds eight 1.5V AA-type penlight
batteries. To install the batteries, first slide the battery
chamber lid in the direction of the arrow, and open the
lid (1) . Remove the battery clip. Load the batteries
making sure that the positive and negative (+ and - )
poles are aligned correctly as shown inside the battery
clip . Put the battery clip back into the chamber, making
sure that the contacts go in first (2). Then, slide the
lid back into place. When replacing batteries, replace
all eight at once.
To connect the battery unit to the lens, plug one end of
the power cord 5C-21 (supplied with the lens) into the
power socket on the lens barrel by aligning the arrow on
the plug with the T mark next to the socket (3). Then ,
align the white dot on the other end of the plug with the
metallic dot near the edge of the LD-2's power socket,
and push the plug into the socket until it clicks into
place (4) .
To remove the plug from the DC unit, grasp the plug by
its metal locking ring and pull it out.
Caution: Before connecting the power cord SC-21 to or discon.necting it from the LD-2, make sure that the power switch is
off. Otherwise, the ringlight might be damaged.
• AC Power Unit LA-2
Before using the AC unit, make sure the voltage selector
is set for the proper voltage. The unit has separate settings
for 220 and 240 volts. Insert a small coin in the slot and
turn the screw so the slot points to the proper setting (220
or 240) . The 100 and 117 volt settings shown in the photo
(1) cannot be used . To use the 100 or 117 volt settings, take
the unit to your nearest Nikon service centre for adjustment.
To connect the AC unit, plug one end of the power cord
SC-21 into the power socket on the lens barrel by aligning
the arrow on the pi ug with the T mark next to the socket
(2) . Next, align the white dot on the other end of the plug
with the metallic dot near the edge of the LA-2's power
socket, and push the plug into the socket until it clicks into
place (3) . Finally, plug the AC cord into a wall outlet. When
the AC unit is switched on, the pilot lamp on top of the
unit lights up immediately. To remove the power cord's plug
from the AC unit, grasp the plug by its metal locking ring
and pull it out.
Caution 1: The grounding cord (supplied with the LA-2) should be
plugged into the ground terminal at the back of the AC power unit
to ground the system whenever possible. (See page 21 for details) .
Caution 2: Before connecting the power cord SC-21 to or disconnecting it from the LA-2, make sure that the power switch is off.
Otherwi se, the ringlight might be damaged.
7
-OPERATION-continued----------------------CONNECTING THE SYNC CORD
Two separate sync cords are supplied with the lens.
Select the cord best suited to your type of camera .
• 2-Pin Sync Cord SC-20
The 2-pin sync cord is for use with all Nikon and Nikkormat cameras, except the Nikon F-301 / N2000 ~ FG , FG-20
and EM. Connect one end of the 2-pin cord to the sync
socket on the lens barrel by aligning the arrow on th e
plug with the ~ mark next to the socket . Then, plug the
other end into the sync term inal on the camera. This end
of the sync cord is threaded for positive connection to
the camera's sync term inal. If you are using a Nikkormat
FTN which has two sync terminals on th e sid e of th e
body, connect the sync cord to the X terminal.
* In
the U.S .A. and Canada, the Nikon F-301 camera is sold as
the Nikon N2000 .
8
• 3-Pin Sync Cord SC-22
The 3-pin sync cord can be used with all Nikon and
Nikkormat cameras having standard ISO-type hot shoe.
When the SC-22 is used with the Nikon F3-series*, FA,
FE2, FE, FM2, F-301/N2000, FG, FG-20, or EM, the
camera's ready-light in the viewfinder operates, so you
can take pictures without removing your eye from the
viewfinder. In addition, with the Nikon F3-series, FA,
FE2, FE, F-301/N2000, FG, FG-20, or EM camera set
for automatic operation or at certain manual shutter
speeds, the proper sync speed is automatically set by turning on the power supply for the Medical-Nikkor 120mm
f/4 IF lens. (For details about automatic switchover to
flash sync speed, refer to your camera's instruction manual.)
To use the 3-pin sync cord, first plug one end into the
sync socket on the lens barrel by aligning the arrow on
the plug with the ~ mark next to the socket. Then, slip
the other end into the camera's hot ~ hoe until it stops,
and tighten the attachment screw.
* Use of the
Flash Unit Coupler AS -4 or AS -7 is required.
9
-OPERATION-continued----------------------SETTING THE ASAjlSO FILM SPEED
The flash output of the ringlight varies according to the
setting of the ASA/ ISO ring. To get correct exposure
with the ringlight flash, you must first adjust the AS A/
ISO ring for the film in use. To do this, loosen the
locking screw on the ASAjlSO ring and turn the ring
until the number corresponding to the ASAjlSO of your
film is opposite the index mark. It is possible to set any
film speed from ASA/ISO 25 to 800. Dots between the
numbers on the film-speed scale represent intermediate
settings such as 32, 40, etc. (see illustration). Once you
have lined up the ASA/ISO number, retighten the
locking screw to hold the ring in place.

SETTING THE SHUTTER SPEED DIAL
The shutter speed setting necessary for proper flash
synchronization depends on the type of sync cord used,
the film speed set on the lens ASA/ISO ring and the
Nikon or Nikkormat camera you are using. Please refer
to the table below for the appropriate shutter speed
setting.

- OPERATION-continued- - - - - - - - - - -- - - - - - - - - - - READY-LIGHT INDI CATION
After the power supp ly is switched on, a red LED
ready-light, built into the top of the lens barrel, lights up
as soon as the ringlight is ready to fire. When the shot is
taken, the ready-light goes out, but then comes back on
as soon as the ringlight is recycled and ready to fire
again. In addition, with the OAT A button on, the
reproduction ratio visible inside the viewfinder serves
as a ready-light. Thus, you can take pictures with any
Nikon or Nikkormat camera without removing your eye
from the viewfinder.
If the Medical-Nikkor is used in conjunction with the
SC-22 sync cord and the Nikon F3-series (via AS-4 or
AS-7), FA, FE2, FE, FM2, F-301jN2000, FG, FG-20,
or EM (see t he previous section, "Connecting the Sync
Cord"), the ready-light inside the camera's viewfinder
operates, too.
12
FOCUSING/DETERMINING THE EXPOSURE
This lens focuses in the same way as other Nikon/Nikkor
lenses do. Therefore, if the reproduction ratio is less
important to you, simply turn the focusing ring until
the subject appears sharp in the viewfinder. However,
if you wish to take pictures at a certain reproduction
ratio, first set the focusing ring to the desired setting
(e.g. 1/4X) and then move in and out until the subject
appears sharp. This will produce photographs at a
predetermined reproduction ratio.
Because the focusing ring is coupled to the diaphragm ,
once the lens is focused, the aperture is simultaneously
set to provide the correct exposure when using the
ringlight.
If the ambient light is dim, use the focusing lamp to
illuminate the subject. (For details, see page 18.)
Note 1 : If you are using a camera with a split-image rangefinder
and/or microprism focusing aid, they may become dark and
cannot be used. In this case, focus on the surrounding matte
fiel d instead.
Note 2: If you want to convert the distance scale to feet, use the
distance scale conversion sticker provided. First peel off the
sticker's backing; then attach the sticker to the focusing ring on
top of the meter scale.
13
- OPERATION - continued- - - - - - - - - - - - - - - - - - - - - - - SETT ING THE REPRODUCTION RATIO
To set the reproduction ratio between 1/11 X and 1 X,
simply turn the focusing ring until the desired reproduction ratio on the white scale clicks into place. If you
want to shoot at magnifications between O.8X and 2X,
attach the 2X close-up attachment lens (as described
below), and set the focusing ring to the appropriate
reproduction ratio on the orange scale.
Once the reproduction ratio is set, both the focused
distance and aperture are automaticall y set.
Use the table on the next page to determine the reproduction ratio according to the focused distance and the
desired subject area .
• Mounting the 2X Close-Up Attachment Lens
Before mounting the 2X close-up attachment lens, make
sure the aperture of the prime lens is set to f132. Then,
grasp the attachment lens by its knurled ring, insert the
threaded portion into the hole in the center of the
ringlight, and while app lying slight pressure, screw the
lens clockwise until it stops. Proper exposure value is
then obtained according to the continuously variable
reproduction ratio between O.8X and 2X.
The attachment lens can be removed with the aperture
set to any value.
Note: With the attachment lens attached, the operative aperture
is fixed at f/32 regardless of the aperture set on the scale.

-OPERATION-continued----------------------IMPRINTING THE REPRODUCTION RATIO
The OAT A button on the side of the lens barrel
determines whether or not data will be displayed in the
viewfinder and imprinted on the film.
When the OAT A button is pushed once, it remains in
the down or ON position. In this case, the reproduction
ratio set on the lens appears in green at the lower righthand corner of the viewfinder image as soon as the
ringlight flash is ready to fire. Because the data glows
when the flash is recycled, you can use it as a ready-light.
Then, at the instant of exposure, the data is imprinted at
the same place on the film frame. With the 2X close-up
attachment lens in place, the reproduction ratio between
O.8X and 2X will be displayed and imprinted in green.
Press the OAT A button a second time, and it returns to
the up or OFF position. With the button in this position,
data is not visible inside the viewfinder nor will it be
imprinted on the film.
If you shoot with the focusing ring set between clickstops, the reproduction ratio will not be shown correctly
inside the finder. In this case, make sure the OAT A
button is in the OF F position, so that the incorrect data
will not be imprinted on the film.
Note: When using color film, the imprinted data may be difficult
or impossible to read if the background in the lower right-hand
corner of the frame is green; with black·and-white film, it may
not show up if the background is light in tone .
16
STOP-DOWN EXPOSURE MEASUREMENT
Although the lens has a built-in ringlight for shooting,
you can take pictures without it. In this case, use the
stop-down method for exposure measurement. When
focused or set to a particular reproduction ratio, the
Medical-Nikkor is also automatically set to a particular
aperture, which can be read off the focusing ring. Then,
to get the correct exposure, you must depress the
camera's depth-of-field preview button to stop the
lens down to the taking aperture prior to using the
camera on Automatic or before adjusting the shutter
speed manually. (For details about stop-down exposure
measurement, refer to your camera's instruction manual.)
Note : If the automatically or manually selected shutter speed is
below approx. 1/125 sec., the use of a tripod to support the camera/lens assembly is recommended . Otherwise, the photograph
will come out blurred because of camera shake.
17
-OPERATION-continued----------------------FOCUSING LAMP
If the ambient li ght is dim, push the LAMP button to
illuminate the subject for focusing. After removi ng
your finger from the button, the lamp stays on for 16
seconds, then turns off automatically to conserve power.
If necessary, you can press the button once again. After
taking a picture using the ringlight, the focusing lamp
immediately goes out. To turn the focusing lamp off
before the 16-sec. automatic timing period is up, simply
switch off the power supply.
If the focusing lamp fails to light up after the LAMP
button is pushed, it needs replacement. First, remove the
power cord from the lens; then remove the lamp cover
by unscrewing it counterclockwise. Then, whil e applying
pressure, turn the old bulb counterclockwise and replace
it with a new one. Align the protrusions at the base of
the new bulb with the notched portion of the lamp
housing and, while app lying pressure, turn the bulb
clockwise until it is fully seated into position. Finally,
replace the lamp cover. For your convenience, a spare
bulb is provided with the lens.

C A U T I O N S - - - - - - - - - LENS CARE- - - - - - - - 1. Due to the electrical characteristics of the MedicalNikkor's ringlight flash and focusing lamp, this lens
should not be used in an explosive environment (i.e.,
an oxygen-enriched atmosphere) or in close proximity
to highly combustible materials (i.e., high -pressure gas
bottles).
.
2. To eliminate any possibility of electric shock, the
following precautions should be observed when using
the Medical-Nikkor lens with the AC or DC power
unit.
. Do not attempt to repair the AC or DC power units
yourself. Tampering with their internal circuits with
the cover removed can result in a dangerous electric
shock. Leave repairs to an authorized Nikon dealer
or send the unit directly to the manufacturer .
• Be sure to turn the power switch to the "OFF"
position before opening the battery compartment to
replace the batteries in the DC power unit. Touching
the terminals with the switch in the "O N" position
can cause an electric shock.
20
• Although you should always keep the lens surfaces
clean, rough cleaning must be avoided . Wipe with
a soft, clean cotton cloth moistened with alcohol
to remove grease or fingerprints from the lens
surfaces.
If you use ether in cleaning the lens, a smudge
sometimes appears on the surface of a multi coated lens. If this happens, wipe it again with a
cotton cloth moistened with alcohol.
• Keep the lens cap in place whenever the lens is not
in use .
• Attach both the front and rear caps when the
