Instructions
Congratulations on your purchase of the Mamiya 645 PRO
Mamiya pioneered the 6x4.5 film format and introduced the world’s first 645
SLR in 1975. The 645 PRO is the latest masterpiece in this series and
incorporates all the latest mechanical, electronic and optical advances. Its
external appearance, too, has been modernized and its ergonomic design
further enhanced.
We are sure that you will enjoy the many advantages this camera and its
accessories offer and want to particularly mention:
The 645 PRO has a built-in self-timer (delayed shutter release) which will also
facilitate time exposures. Attaching special leaf shutter lenses will automatically set the focal plane shutter to 1/8 sec. Heavy duty gears connect to the
improved Power Drive Grip WG401. This grip also automatically cocks the leaf
shutter lenses and permits remote control.
The AE Prism Finder FE401, specially created for this camera, automates
exposure and shows LED safety signals. 35mm film holders now come with
panoramic adapters. A super fast 300mm f/2.8 APO lens was also designed
for this camera.
We are convinced that your camera will serve you well, because we have
designed it for heavy professional use. However, we ask you to please read
all operating instructions carefully before you put your equipment to work, in
order to ensure proper operation and maximum results.

This manual covers the
basic camera. Separate instructions are
supplied with all system accessories, including lenses,finders,
film holders, etc.

Two new convenient safety features have been added to
the 645 PRO in the form of state-of-the-art optoelectronics
which immediately identifies problems with the shutter
(i.e. when it will not release) when the AE Prism Finder
FE401 is used. Whether these malfunctions develop from
failure to draw out the Dark Slide, or if there are problems
in film take-up, the LED will indicate the source of the
trouble. With these new advancements, Mamiya believes
the most demanding pro will be more than satisfied with
the new edition 645.
3 x More Negative Area Than the 35mm Format
Plus Superior Image Quality From Mamiya WorldClass Lenses
The 6x4.5cm format offers approx. 3 times more image
area than the 35mm (24x36mm) format, Man’s vision is
horizontal and rectangular.
Film Holders are rectangular and so are most pictures in
them. The 6x4.5 format is also large enough to be viewed
without a magnifier and its aspect ratio (horizontal / vertical)
is ideal, requiring minimum cropping. Mamiya’s high
performance medium format lenses assure sharpness
and beautiful color fidelity.

Sturdy, Versatile, Safe and Highly Reliable Body
2 - Tailored to Satisfy Pro Needs -
The 645 PRO features an interchangeable film holder
system capable of using a far wider range of roll film
holders than before. Depending on the application, the
system can be quickly attached to or detached from the
camera, ensuring the ability to catch even fast changing
scenes. It also features fail-safe devices including, for
example, one that warns when you have failed to take out
the dark slide when the AE Prism Finder FE401 is being
used.
Introduced in 1975 to not only provide an alternative to
the 35mm format, but to afford the user with advanced
versatility given its much larger format, the Mamiya 645
Series is constantly being upgraded. Elements such as
speed and handling plus a host of other special features
have been enhanced to satisfy the needs of most demanding professionals.

used when the AE Prism Finder is
attached to camera.
1. If it is not attached and the dial is
set to either of these positions, the
shutter release will not work.
2. If it is not attached and the SelfTimer is activated, the Pilot Lamp
will Iight for 10 seconds but the shutter will again not release.
If the Shutter Speed Dial is set between click stops either the higher or
lower exposure speed may result.
22
Set the desired f/stop on the Aperture Ring (A) by aligning the f/number
with the red reference dot (B) in the
center of the Scale Ring. The Aperture Ring has a click stop for each f/
stop. In-between clicks can also be
used.
The effect the set f/stop will have
upon the picture area can be confirmed on the Finder Screen.
Move the AM Lever on the lens so
that “M” becomes visible - the lens
then can be stopped down to the
preselected aperture.
23
*At position “A”, the lens is always stopped down only when
the shutter is being released with
the aperture being open.
* During normal photography,
set the AM Lever so that “A” is
visible. At “M”, focusing will be a
little difficult.
* When using the AE Prism
Finder, be sure to set the AM Lever on “A”; otherwise, correct
exposure cannot be obtained.
*When aperture has been confirmed, be sure to reset the AM
Lever to “A”.
See “Depth-of-field” on page 25.
Focusing with the Standard Focusing Screen N Type E
While looking through the viewfinder,
turn the lens Focusing Ring until the
most important subject part appears
sharp and clear.
1. The camera comes equipped with
a bright, Type E, RangefinderlMicro-prism Focusing Screen. It features a center, split-image rangefinder spot and the subject is in
sharp focus when the split images
combine into one.
2. The microprism ring around the
split-image center further facilitates
focusing. The microprisms disappear only when the subject is in
sharp focus.
24
3. The rest of the ground glass area
can also be used for focusing.
* Interchangeable Focusing
Screens
There are four additional focusing screens available for specialized applications. They are easy
to interchange and come with instructions.
Reading the Depth of Field Scale
Depth of field is defined as the zone
of sharpness before and behind the
plane of focus. It depends on camera subject/distance, focal length of
lens, aperture setting and distance
the lens is focused at.
In addition to visual observation, the
Depth of Field can be determined by
using the Depth of Field Scale on
each lens. f/stop numbers appear
on both the right and left side of the
red index mark in the center of the
scale ring. Simply read the figures
which appear above the f/stop numbers on the distance scale of the
Iens.
25
For example, with the 80mm f/2.8N
lens focused at 3m and the aperture
set at f/22, the depth of field scale
indicates that the zone of sharp focus will extend from about 2m to 6m.
* Move the empty spool from the
top to the lower (take-up) compartment, ready for loading the
next film roll.
* Never load, unload or handle
film in direct sunlight.
1. Giving the Film Advance Crank
one complete turn, will cock the
shutter and mirror and ready the
camera for the next exposure.
2. When the film is completely exposed (15 exposures on 120, 30 on
220 film), the crank stop will disengage. Continue turning until the paper trailer is completely wound onto
the take-up spool. (About five turns
after the last exposure.)
3. Open the Back Cover. and remove the Roll Film Insert. The Exposure Counter will return to S (start)
automatically.
4. Pull the Spool Clip on the roll film
insert out to remove the film.
5. Remove the film from the roll film
insert; make sure that the film on the
roll does not loosen, and seal immediately.
26
To use the Self-Timer, set the Shutter Release Selector to 0 and press
the Shutter Release Button. The
Battery Check Lamp will light for 8
seconds and blink for 2 seconds,
whereupon the shutter will go off.
* After using the self-timer mode,
be sure to return the Shutter Release Selector to the White
Square. (Normal mode.)
+ To override the self-timer, after
having pressed the release, move
the selector back to the white
square.
*The Self-Timer can also be
overridden by inserting the Dark
Slide into the Film Holder or setting the camera Shutter Speed
Dial to “B”.
27
Aligning the white dot of the Multiple
Exposure Lever with the yellow
“MULTI” square, disengages the
multiple exposure prevention
mechanism, and the film will not
advance after an exposure is made
and the Film Advance Crank is
turned. However, the shutter will be
recocked, thus making multiple exposures possible. In this mode the
Exposure Counter will not advance.
* To override the multiple exposure mode or to return to normal
operation, be sure to return the
lever’s White Dot against the white
squareandthenadvancethefilm.
(If you forget you will continue to
make multiple exposures on the
same frame.)
will stay open until the shutter release is pressed again. You may
also use a cable release together
with the cable release adapter. (The
battery circuit will automatically
switch off to save power.)
* “B” can be terminated by shift-
ing the Shutter Release Selector
from $) or the Shutter Speed
Dial from “B”.
For time exposures set the Shutter
Release Selector to 0, the selftimer mode, and set the Shutter
Speed Dial to “B”. Press the shutter
release and both mirror and shutter
28
This is an important feature when
the tripod mounted camera is used
at slow or long exposure times and
particularly also with use of long
telephoto lenses. It eliminates the
possibility of even the slightest “mirror bounce ”which may affect image
sharpness.
Move the Mirror-up Lever to the
yellow "M.UP" square, after you have
composed and focused your picture. This will raise the mirror and
the viewfinder image will be blacked
out. After use, return lever to normal
(white square) position.
29
*When using the AE Prism
Finder, set the Shutter Speed Dial
to “AEL”. Press the shutter release halfway and then lock the
mirror up. If set to “A” and the
mirror is locked up, “LT” (long
time) will appear in the finder display and correct exposure cannot be obtained.
* When using a Leaf Shutter
Lens, be sure to read the instructions accompanying it.
Infrared light rays - being of longer
wavelength - focus at a slightly different plane and require the following adjustment:
1. Note the Red Index Mark against
which you read your distance scale.
The red infrared index mark is slightly
to its right.
2. After focusing in the usual manner, read the distance scale and
move it to the right to line up with the
infrared index mark.
* For proper filter and exposure
information be sure to consult
the instructions enclosed with infrared film.
* The A300mm f/2.8 APO lens for
645, being also corrected for infrared light rays, does not need
an Index Mark for infrared.
30
When using the Hot-shoe,
be sure to put an appropriate Safety Cover over the Xsync terminal so that you
won’t receive a high voltage
electric shock if the terminal
is accidentally touched. (A
Safety Cover is put on the Xsync terminal when the
camera leaves the factory.)
1. When using an electronic flash,
plug the synchronization cord into
the Sync Terminal and set the Shutter

* If the camera should fail to function properly,
please check the following:
1. The Shutter Release Button does not move.
Push the Battery Check Button.
If the lamp does not light, check:
Is a Battery in the camera?
If yes, is it correctly inserted? (Polarity)
Is it dead?
2. The finder is black or very dark.
Has the Lens Cap been removed?
Is the Mirror-up Lever in the “M.UP” position?
If so, turn the lever to the White Square.
Is the “AM” setting on the lens at “M" (Depth of
Field Preview)?
If so, move it to “A”.
3. The Roll Film Holder cannot be removed from the
camera body.
Insert the Dark Slide.
If the lamp does light, check:
Has the Film Holder Dark Slide been pulled?
Is the Shutter Release Selector in the locked
(Red Dot) position?
If so, move it to the White Square and try again
Is the Shutter Speed Dial in the “A” or “AEL”
position?
If so, turn to other setting and try again.
4. The developed film has fewer exposures than
specified.
Most likely the Start Mark had not been aligned
properly when the film was loaded. (See load
ing instructions page 20 )
5. The Film Advance Crank continues to turn and does
not stop.
Was the Roll Film Insert placed in the Roll Film
Holder?
Was the empty fim spool left in the upper
compartment?

Things to Watch
* Cold Temperature Photography
a. Use a fresh lithium battery
* When using the AE Prism Finder FE401
When using this finder it is imperative that the
Film Speed Dial on the Roll Film Holder is properly set for the ISO number of the loaded film, as
it interfaces with this finder. If not done, wrong
exposures may result.
b. Utilize the External Battery Case accessory.
(Permits battery to be placed inside clothing).
Batteries that fail at low temperatures may still
be used at normal temperatures. However frequent temperature changes shortens battery life.
c. Avoid sudden temperature changes when going
indoors, to prevent moisture condensation on
camera and lenses. (Also important for film
protection).
*When the mirror is locked in the up position.
* The Focal Plane Shutter Curtain may be damaged if the camera faces strong light sources,
especially the sun. Return mirror to normal position or cap lens to prevent such damage.

The AE Prism Finder FE401
The Mamiya AE (Automatic Exposure) Prism Finder
FE401 pentaprism guarantees a true, upright image
and features built-in electronic shutter control which,
ensures aperture-priority, TTL automatic exposure
metering while in the A or AEL mode.
< 3-Way Metering System>
The FE401 comes with three metering modes: average
metering (AV), spot metering (SP), and AV-SP metering
capable of automatically selecting AV or SP according
to subject conditions.
The LED display in the viewfinder indicates correct
exposure
If you forget to extract the Dark Slide when the finder is
being used with the 645 PRO, an LED will flash a
warning.
The Power Drive Grip WG401
The Power Drive Grip WG401 is integral with the
winder and hand grip, enabling quick and continuous
exposures to be taken: frames can be advanced (about
2 frames/sec.).
Usable with any of three recently developed leaf shutter lenses, it can be connected with the lens and winder
with the Grip Connecter PL401, thus automatically
interlocking it with the lens.

Periodic Check
Periodically check the camera to make sure that it is in
good working order, especially before an important
assignment. Check the battery, flash synchronization,
mirror and shutter movement, film advance, diaphragm
operation, etc.
Should any malfunction occur or if the camera has
been dropped, jarred or become wet, do not attempt to
fix it yourself but send it to the Service Department of
your Mamiya distributor.
When the camera is not used for a long period of time,
remove the battery and any film from the camera.
Avoid storing the camera for prolonged periods of time
in a damp or salty atmosphere. (Color film should be
stored at the manufacturer’s recommended temperatures.)
Since cameras are precision instruments, avoid shocks
and rough handling.
When camera and lens are stored for a long time,
periodically exercise the shutter(s) at various speeds
and also turn the lens diaphragms.
Cleaning
Never touch the surface coated mirror. Clean dust
particles with a blower and optical surfaces with lens
cleaning tissue and lens cleaner.
