Congratulations. You now own the MD4 Motor
Drive, an accessory designed to advance
the film automatically through the Ni*on
F3 camera. The MD-4 offers either "Single"
or "Continuous" operation. At "S," the
film advances to the next frame as soon
as the picture is taken. At "C, "it will
be advanced at 4 frames per second with
penlight batteries or at 6 fps when us-
ing the optional MN-2 NiCd Battery Unit.
In addition, the MD-4 offers automatic
film rewind. Even though the MD4 is ex-
tremely easy to use, you should still
familiarize yourself with its basic op-
eration as presented in the first sec-
tion. For more detailed explanations and
special picturetaking situations, refer
to the sections CONTROLS IN DETAIL and
ACCESSORIES. A few minutes wisely in-
vested now will pay off in years of re-
warding photographic experiences.

teries into the clip following
the " + " and "-" indications.
5.Install the battery clip.
Put the clip back in the bat-
tery chamber (13). Push it un-
til it snaps into place.
6.Check the battery power.
Push the battery check button (1)
If both LED's (9) light up, the
batteries have been loaded prop-
erly and their power is suffi-
cient. If one LED glows, the bat-
teries should be replaced with a
fresh set. If none go on, this
indicates that the batteries have
not been loaded correctly or are
completely dead.

BASIC OPERATION continued
7.Attach the motor drive to the camera body.
Make sure the S-C mode selector (15) of the
motor drive is set to L (Lock) before attaching
the camera. Otherwise the motor might start
operating. Place the camera body on top of the
motor drive so that the motor drive's mounting
screw (20) lines up with the camera's tripod
socket and the camera positioning pin (17) is
aligned with the motor drive coupling hole.
Then turn the attachment wheel (21) counter-
clockwise until the two units are screwed tightly
together.
8.Load the camera with film.
Load film into the camera in the normal way.
Note: Do not detach the motor drive from the
camera while it's still loaded with film. Unless
you are in o darkroom. the film might become
exposed to liqht entering through the bottom of
the camera.

12.Rewind the film automati-
cally.
When the film reaches the end
of the roll, it will automati-
cally stop and one LED will light
up. Depress the lock button (11)
on rewind slide I (R1) (12) and
push the slide to the left. Then,
while holding it, push rewind
slide 2 (R2) (5) up. Immedi-
ately the film starts rewind-
ing. When the sound becomes more
high-pitched, push rewind slide
2 back down to stop film re-
winding.
13.Remove the film cartridge.
Unload the camera in the normal
manner.
14.Turn the S-C mode selector
to the L-setting.
To prevent the shutter from
being accidentally tripped be-
tween shooting sessions, turn
the S-C mode selector to the L
(LOCK) position.

10
Anatomical Grip (18)
The MD-4 features a new anatomical grip to permit
the photographer to shoot either horizontal or
vertical pictures comfortably. For horizontal
shooting, hold the grip so that your thumb is
behind the camera and your forefinger is on the
trigger button. In this way, you can change quickly
from horizontal to vertical shooting. However,
another way to hold the motor drive vertically is
to balance the grip in your palm with your thumb
over the trigger button. This position is recom-
mended for onehanded shooting over an extended
period of time, such as when using a bracket-
mount flash unit off-camera.
S-C Mode Selector (15)
Concentric with the trigger button for easy
access, this dial sets the motor drive for ei-
ther single frame (S) or continuous (C) opera-
tion. There is also a lock (L) position.
At "S" (Single Frame)
At all shutter speeds, except "B" and "T," the
motor drive trips the shutter and winds the
film in a single sequential step. At the same
time, one LED lights up to indicate film ad-
vance. At~the "B" setting, when the trigger
button is pushed, the shutter fires and remains
open until you take your finger off the button.
Then the film advances automatically to the
next frame. At "T," the shutter remains open
until the shutter speed dial is rotated off the
"T" setting.
Note: With the camera's power switch turned on, you can take
motordriven single frame shots by using the camera's shutter
release button. When you depress the button, the shot is taken,
and when you release pressure from the button, the Rlm B wound
to the next frame. This occurs with the S-C mode selector set
to either "S" or "C."
CONTROLS IN DETAIL

11
At “C” (Continuous)
As long as you hold the trigger button down, shots
will be taken rapidly in succession. Any shutter
speed setting, except "B" and "T," can be used. At
shutter speeds slower than 1/125 sec., the firing
rate automatically slows down to match the shut-
ter speed in use.
Motor-driven multiple exposures are possible by
holding the multiple exposure lever in position
while firing off a short burst (see the picture
above). After you're finished, make a blank shot
by covering the lens with a lens cap. This will
advance the film to the next unexposed frame without
adding another shot to the multiple exposure just
completed.
Caution: Do nat hold down the backup mechanical release lever
while shooting on Continuous, as the shutter will not open prop-
erly.
At “L” (Loc)
The trigger button is locked and the motor drive
will not operate. However, by turning on the
camera's power switch, you can use the shutter
release button to trip the shutter and advance
the film manually just as if the MD-4 were not
attached.
CONTROLS IN DETAIL continued

12
Trigger Button (14)
The MD-4's trigger button, because it is an elec-
tromagnetic release, operates in exactly the same
manner as the camera's shutter release button. It
not only trips the shutter but serves as a meter
switch as well. When depressed halfway, it turns
on the meter and activates the LCD exposure in-
formation in the viewfinder. If the button is not
touched again, the meter will turn itself off
automatically after 16 sec. to conserve battery
power.
With the MD-4 attached, it makes no difference
whether the camera's power switch is turned on or
not. In fact, you might find it easier to leave
the switch in the OFF position and control the
camera's meter entirely with the trigger button.
Frame Counter (4)
A subtractive-type frame counter is built into
the MD-4. For normal shooting, set the counter to
the orange dot and forget it. At this setting, the
counter is disengaged and the motor drive stops
automatically when the film tension increases at
the end of the roll.
However, in below-freezing temperatures, film
becomes brittle and easy to break. Therefore, to
prevent the film from being accidentally torn,
set the frame counter to the number of fraEr es on
the roll. When the counter reaches "0," the motor
drive automatically shuts off before the film is
damaged. One LED also lights up as a visual indi-
cation. To set the counter, turn the counter set-
ting dial to the right until the desired number is
aligned with the white index (3). 36, 24, 20, and
12 are in red corresponding to the number of

frames in commercially-available cartridges. You
can also shoot short bursts by setting the counter
to the number you want (Fig. 1). When the counter
reaches "O," the motor drive stops and one LED
lights up (Fig. 2). To reset the frame counter for
another burst, first turn the counter setting
dial to the orange dot and the LED will go out
(Fig. 3). Then you can rotate the counter to the
desired number. Before resetting the counter, make
sure to check the camera's frame counter to de-
termine whether there are enough exposures left
on the roll for the next burst.
Note: If you rewind the film before the frame counter reaches
"O," the counter will not reset properly to the orange dot.
Therefore, before starting to shoot your next roll of film,
make sure to reset the counter to the desired setting.
The film becomes brittle in low temparatures. In cold climate,
be careful not to overestimote the number of frames remaining
on a roll of film since thismayresultin the motor pulling the
Rlm offthe supplyspool or damaging its perforated edges. R may
be a good practice to set the frame counter to one less than the
number af frames remaining on a roll of film. For example, if
you food a fresh S6-exp. roll, set the frame caunter to 35.

14
Rewind Slides 1 (R1) and 2(R2) (5)
When one LED lights up to signal that the film is
at an end, you must rewind the film. To simplify
this operation, the MD-4 features completely au-
tomatic film rewinding. Depress the lock button
on R1 and push the slide to the left. Then while
holding R1 in position, push R2 up. Immediately
the film will start rewinding. When the sound
becomes more high-pitched, this indicates the
leader has been completely rewound back into the
cartridge. To stop the rewinding action, push R2
back down and immediately R1 will spring back
into its original position.
If you were using the frame counter, it moves
from "O" to the orange dot position as soon as
R2 is pushed up.
Rewinding time for a 36-exposure roll of film
with alkalinemanganese batteries is approxi-
mately 8 sec.; with the optional MN-2 NiCd Bat-
tery Unit, it is reduced to 4.5 sec.
Note: If the film is automabcally rewound in cold weather,
static electncity charges may cause accidental expasures re-
sembling lightningLalts to appear an the film. To prevent this
from happening, push R1 to the leff and rewind the film slowly
by hand with the camera's film rewind crank.

Battery Chamber (13)
Instead of using a separate battery pack, the MD-
4 houses its batteries in a built-in battery cham-
ber. The standard MS-3 Battery Clip accepts 8 AA-
type penlight batteries to power the motor drive
up to 4 frames per second. Once the motor drive is
attached, the camera gets all its power from the
batteries in the motor drive. In this way, the
camera is able to run on high capacity batteries.
As a separate accessory, the MD-4 accepts the MN-
2 NiCd Battery Unit for extremely high-speed shoot-
ing up to 6* fps. Since NiCd batteries are better
able to maintain their peak performance in cold
temperatures, the camera/motor drive combination
will still operate down to -20°C. The following
table lists the firing rates according to power
source (Table 1), while the bar graph gives you
the expected life of various battery types under
ordinary temperatures (Table 2).

Battery Check Button(1) and LED Indicators(9)
To check battery power, depress the battery check
button. If both LED's light up, the power is
sufficient to provide the fastest firing rates.
If only one LED comes on, you can still use the
MD-4, but at slower rates. If neither LED lights
up, the batteries should be changed for a fresh
set. The LED's also indicate other camera func-
tions. One LED will light up: 1) each time the
film is wound after a shot is taken; 2) when the
film reaches the end of the roll and needs rewind-
ing; 3) when the frame counter reaches "0"; or 4)
when auto-rewinding is stopped with the optional
MF-6 Camera Back.
Note: One LED will also hght up if the batteries become so weak
that the motor dNve can no longer advance the hlm and just stops
during the course of shooting.
Electrical Terminals
The MD-4 is provided with three separate electri-
cal terminals.
1) Magazine back terminal (19)
Located at the bottom of the motor drive's grip,
the magazine back terminal allows a magazine back
to be connected to the MD-4's electrical system.
2) External power terminal (23)
The smaller of the two terminals on the front of
the motor drive's base, the externalpower termi-
nal allows the MA-4 AC/DC Converter to be con-
nected to the MD-4 for extended studio shooting.
3) Remote terminal (24)
The larger of the two, the remote terminal allows
a variety of remote control devices to be at-
tached.
