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 automati-

cally 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 lea

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. Sepa-

rate instructions are

supplied with all sys-

tem accessories, in-

cluding lenses,finders,

film holders, etc.

For additional informa-

tion please feel free to

contact your author-

ized Mamiya dealer or

the Mamiya importer in

your country.

3 x More Negative Area Than the 35mm Format

Plus

Superior Image

Quality

From Mamiya World-

Class 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

Tailored to Satisfy Pro Needs

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 de-

manding professionals.

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.

Enhanced Interchangeable Roll Film Holder System

Enables Polaroid and Even 35mm Panoramic

Photography

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.

Interchangeable Viewfinders

1. AE Prism Finder FE401

The AE (automatic exposure) Prism Finder FE401 fea-

tures three modes of TTL metering, including automatic

switching from center-weighted averaging to spot me-

tering. It also has a

+/-3EV

exposure compensation ad-

justment.

2. Prism Finder

PF401

The Prism Finder

PF401

is without metering electronics

and designed for manual photography mode. Both Prism

Finders show an unreversed, upright image and are ideal

for eyelevel photography.

3. Waist Level Finder N

The Waist level Finder N is desirable for low angle

photography and particularly for horizontal composition.

A self erecting hood with built-in magnifier shields

groundglass from all ambient light. A built-in sportsfinder

permits eyelevel viewing and is ideal for action photog-

raphy.

Bright, Dynamic Images Visible on the Focusing

Screen

5 Selectable Types Available

The 645

PRO can reproduce bright, dynamic and sharp

images on the focusing screen, enabling optimum com-

position to be obtained according to the photographic

purpose. In addition, the 645 PRO greatly enhances

focusing.

5 types of focusing screens are available to facilitate

photographing a wide variety of subjects.

A Comprehensive Series of Interchangeable Lenses

- Sharp Images and Outstanding Color Balance -

There are an amazing variety of interchangeable lenses

in the PRO 6 x 4.5 format series. Mamiya has concen-

trated an all-out effort on the systematic production of

lenses in an effort to satisfy a multitude of needs. All

lenses are multi-coated to eliminate flare and ghosting

even under the most adverse light conditions. While the

series now also features three leaf shutter lenses, all

lenses exhibit the utmost in color balance, high

resolu-

tion and crystal clear definition. A feature lens is the new

300mm f/2.8 APO lens which eliminates chromatic aber-

ration and produces photos with the sharpest definition.

Given the wide variety of lenses in the 645 PRO Series,

they greatly expand the world of images that are possible.

Auto winding with the Power Drive Grip WG401

This Power Drive Grip WG401 has been specially de-

signed for heavy duty, motorized operation with the 645

PRO. It also permits automatic shutter cocking of the leaf

shutter lenses and can be remote controlled. Another

feature, not available previously is the following:

When attaching a partially exposed film holder (in which

the film has not been advanced to a new frame), to the

645 PRO equipped with the Power Drive Grip WG401, a

built-in camera mechanism will automatically advance

the film to the next frame, when the shutter release is

activated, either on the camera body or on the Power

Drive Grip WG401.

New Automatic Leaf Shutter Lenses for added

versatility.

55mm (Wide Angle), 80mm (Standard) 150mm

(Telephoto) lenses

These

lenses are all in Seiko #0 shutter, offer the advan-

tages of syncroflash photography at all shutter speeds

30,

1/60,

1/125,1/250 and

1/500sec.

The optional Power

Drive Grip WG401 will automatically cock the shutters as

it transports the film and moves the mirror.

The camera’s focal plane shutter must be set at 1/8 sec.

for leaf shutter mode operation. The leaf shutter lenses

can do it automatically.

A Broad Accessory System

For Specialized Applications

A useful accessory system to serve the specialized

needs of the photographer. It includes Auto Bellows and

Auto Extension Rings for close-up and copying work;

Infrared Remote Control for studio and nature photogra-

phy; External Battery Case for operating in cold sur-

roundings; Camera Grips for convenient holding and

more.

Other Features

After focusing, the

Mirror

can be locked up before making

an exposure. This is convenient when the camera is used

at slow shutter speeds and is mounted on a tripod for

telephotography, copy work, etc., since even

a very

small

amount of vibrations should be eliminated.

<Self-timer>

Self-timer for delayed shutter release. When activated it

will light a red pilot lamp in the front of the camera for eightlamamp in the front

seconds and will blink for two seconds before triggering

the shutter.

Time exposures are made by utilizing the Self-timer and

the “B” shutter setting. A new power saving circuit design

switches the battery off and extends is life.

This eliminates the need of having

to manually reset the meter, every

time you change film holders loaded

with different films. Therefore make

it a routine to always set this dial

with the speed of the loaded film.

The Memo Clip on the back of the

Roll Film Holder Cover accepts the

box top of the film carton and can

also be used for other reminders.

little difficult.

* When using the AE Prism

Finder, be sure to set the AM Le-

ver on “A”; otherwise, correct

exposure cannot be obtained.

*When aperture has been con-

firmed, be sure to reset the AM

Lever to “A”.

See “Depth-of-field” on page 25.

While looking through the viewfinder,

turn the lens Focusing Ring until the

most important subject part appears

sharp and clear.

Focusing with the Standard Focusing Screen N Type E

The camera comes equipped with

a bright, Type E, RangefinderlMi-

cro-prism Focusing Screen. It fea-

tures a center, split-image

range-

finder 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 disap-

pear only when the subject is in

sharp focus.

The rest of the ground glass area

can also be used for focusing.

Interchangeable Focusing

Screens

There are four additional focus-

ing screens available for special-

ized applications. They are easy

to interchange and come with in-

structions.

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 cam-

era subject/distance, focal length of

lens, aperture setting and distance

the lens is focused at.

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 num-

bers on the distance scale of the

Iens.

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

fo-

cus will extend from

about 2m to 6m.

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 ex-

posed (15 exposures on

120, 30

220 film), the crank stop will disen-

gage. Continue turning until the pa-

per trailer is completely wound onto

the take-up spool. (About five turns

after

the

last exposure.)

Move the empty spool from the

top to the lower (take-up) com-

partment, ready for loading the

next film roll.

Never load, unload or handle

film in direct sunlight.

3. Open the Back Cover. and

re-

move the

Roll

Film

Insert. The Expo-

sure Counter will return to

(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 imme-

diately.

To use the Self-Timer, set the Shut-

ter Release Selector to

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

Re-

lease 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 set-

ting the camera Shutter Speed

Dial to “B”.

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 ex-

posures possible. In this mode the

Exposure Counter will not advance.

To override the multiple expo-

sure mode or to return to normal

operation, be sure to return the

lever’s

at slow or long exposure times and

particularly also with use of long

telephoto lenses. It eliminates the

possibility

even

the slightest “mir-

ror

bounce ”which may affect image

sharpness.

Move the Mirror-up Lever to the

yellow "M.UP" square, after you have

composed and focused your pic-

ture. This will raise the mirror and

the viewfinder image will be blacked

out.

After use,

When using the AE Prism

Finder, set the Shutter Speed Dial

to “AEL”. Press the shutter re-

lease 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 dis-

play and correct exposure can-

not be obtained.

* When using a Leaf Shutter

Lens, be sure to read the instruc-

tions accompanying it.

Infrared light rays

being of longer

wavelength - focus at a slightly dif-

ferent plane and require the follow-

ing 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 man-

ner, 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 in-

frared film.

The A300mm f/2.8 APO lens for

645,

being also corrected for in-

frared light rays, does not need

an Index Mark for infrared.

(Without Battery)

If the camera should fail to function properly,

please check the following:

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?

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.

2. The finder is black

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.

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

)

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

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 prop-

erly set for the ISO number of the loaded film, as

it interfaces with this finder. If not done, wrong

exposures may result.

*When the mirror is locked in the up position.

* The Focal Plane Shutter Curtain may be dam-

aged if the camera faces strong light sources,

especially the sun. Return mirror to normal po-

sition or cap lens

prevent such damage.

Cold Temperature Photography

a. Use a fresh lithium battery

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 fre-

quent 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).

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

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

frames/sec.).

Usable with any of three recently developed leaf shut-

ter lenses, it

can

be connected with the

lens and

winder

with the Grip Connecter

PL401,

thus automatically

interlocking it with the lens. 39

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

salty atmosphere. (Color film should be

stored at the manufacturer’s recommended tempera-

tures.)

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.

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

become wet, do not attempt to

fix it yourself but send it to the Service Department of

your Mamiya distributor.
