Installing the Battery in the Magazine
Battery Power / Battery Care
●The camera’s power is turned on when the drive
dial is set to “S,” “C” or “M.UP.” In order to prevent
the camera’s batteries from discharging, sleep
mode is automatically established if no operations
are performed for a specific period of time while the
power is ON (with exposure metering status
maintained).
●The initial setting for the exposure metering
status maintenance period is 15 seconds. It can be
changed at any time to a period within a 5- to 60-
second range using the custom settings. (C-04 on
page 93)
Battery power
The button battery supplies power to the magazine's LCD when the film magazine is
detached from the camera.
1. Remove the battery compartment
screw cap.
Use a coin or suitable screw driver and turn it
counter clockwise.
Remaining battery
charge display
● In sleep mode, operating the shutter button or function setting button restores power
ON status.
● In sleep mode, the shutter speed and f-number among the external LCDs go off, and
the marks shown in the figure are displayed. (These marks appear in program AE
mode.)
For the purpose of the descriptions and explanations provided in these
instructions, it is assumed that the camera’s power is on.
2. Insert a battery.
Insert the battery according to the polarity indica-
tion in the battery compartment, and close the
battery cover.
Battery used: Sony CR2032 or equivalent
Batteries Care
■Be sure to insert the battery with the correct
polarity
1. Battery life of the originally supplied batteries is dependant on storage conditions.
2. Blots and fingerprints on terminals may cause loose connection and corrosion. Wipe
them off before loading the batteries.
★ When the magazine is installed onto the body, the power will be supplied to the maga-
zine from the camera body.
3. It is advised to carry spare batteries in remote or foreign locations.
★ You can take shots without installing the battery into the magazine. However, if you
remove the magazine from the body, the magazine does not indicate film sensitivity
or number of shots.
4. Battery performance decreases in low temperatures. Keep them warm when in cold
climates or locations.
External battery case PE401 is available as an optional accessory.
★ The magazine does not have a battery level indicator. When the magazine LCD panel
becomes dark or disappears, replace the battery. As a rough guideline, the battery
should last approx. one year.
5. Store the batteries in a cool and dry place, away from direct sunlight.
6. Remove the batteries from the camera body when they will not be used for a long
time.
7. Replace the batteries with new ones as soon as they are exhausted. Liquid leakage
from the battery may damage the camera.
8. Read the label warnings of the batteries for their handling.

6. Attach the leader paper of the
film to the empty spool.
8. Close the back cover.
Push in the upper part of the back cover firmly to
close it.
Run the film as shown, and insert the tip of the
leader paper into the slit of the empty spool. Wrap
the leader paper around the empty spool once or
twice by rotating it. Further adjustment of the film
position is not necessary. The camera automati-
cally advances the film to the first frame.
Attach the magazine to the camera body. Pull out
the dark slide, and press the shutter release but-
ton halfway. This will advance the film to the first
frame.
Place the dark slide in the magazine's rear stor-
age pocket.
★Press down gently on the loaded film, rotate
the “SPL” side spool so that the film does not
develop any slack, and wind the film tightly. If
the film is not wound tightly, the film winding
will loosen, possibly causing light fogging.
★ In this camera, the film is automatically advanced to the first frame. If it is not ad-
vanced properly, the film will continue winding for a certain period of time, after which
it will automatically come to a stop. If this happens, fewer frames (about 10 frames)
will be available for shooting. To be on the safe side, after taking 10 frames, take the
film out following the procedure for removing the film before reaching the end of the
film. (page 40)
★ When the film is not wound properly, the “- - ” mark appears in the LCD.
★ If you do not operate the camera for 60 seconds, the camera will automatically enter
sleep mode in order to save battery power. In sleep mode, closing the back cover
does not trigger the automatic film advance, even if it is set so in the custom setting
(C-31 on page 96). In this case, press the shutter release button halfway down to feed
the film to the 1st frame position.
7. Insert the loaded film insert into
the magazine.

Pinch the knobs H and place the roll-film insert
in the housing. When the top of knob H is pushed,
the left and right latches open up, and the inner
frame clicks into place.
■ Film might be accidently exposed. Avoid intense light when loading/ unloading film,
and do not wrap too much of the leader paper into the spool.
1. The camera can be set to wind the film to the 1st frame position
automatically after the back cover is closed.

Exposure Compensation
In some situations, such as a great difference between the subject and background
brightness or overall subject tones that will not meter correctly because they are all black

AE Lock Mode
Shooting with the AE lock function is useful in cases where the desired focal point differs
from where the focal point is usually measured, or when it is necessary to measure the
exposure using spot metering in order to bring the desired subject into focus.
The AEL button will lock the Auto-exposure value as the photo is being recomposed.

Electronic Shutter Release Contact
For mirror-up, long exposure, or slow shutter shooting, use the magnetic cable release
RE401 or the remote control RS402 for remote shooting.
Selecting the Number of Frames to be Shot
Under certain shooting conditions, the failure of the film to straighten out may cause
defocusing on part of the screen. When the camera has been left standing for a pro-
longed period (30 minutes or longer) after the film is wound up, the frame following the
frame up to which the film was wound and at which the camera was left standing may be
adversely affected by the failure of the film to straighten out. In cases like this, the effect
can be prevented by setting the number of shooting frames to 15 frames for a 120 film or
30 frames for a 220 film. This failure of the film to straighten out differs significantly
depending on factors such as the type of film used and the temperature or humidity

Depth of Field / Depth of Field Preview
Front / Rear Dial Lock Function
When the Electronic Dial Lock is “On,” all currently set values in “Av” (Aperture Priority
AE), “Tv” (Shutter PriorityAE) and “M” (Manual mode) cannot be adjusted with the front
or rear dials. This prevents accidental change of shutter speed or aperture values.
Depth of Field
Depth of field (D.O.F.) is defined as the zone of sharpness before and behind the plane
of focus. It depends on distance to subject, focal length of lens, aperture setting and
distance the lens is focused at.
How to set dial lock
Press the multiple exposure mode and auto
In addition to visual observation via the depth of field preview button, the D.O.F. can be
determined by using the depth of field scale on each lens. The f/stop numbers appear on
both the right and left side of the white index mark in the center of the scale. Simply read
the figures which appear above the f/stop numbers on the distance scale of the lens.

Infrared Photography
Flash Photography
In addition to its standard flash sync system, the Mamiya 645 AFDIII features TTL (through the
lens), off the film (OTF), electronic flash exposure metering.A flash sensor located inside the
camera body reads the flash reflected off the film surface at the moment of exposure. The
sensor is connected via the Mamiya 645 AFDIIIs dedicated hot-shoe to a shoe- or handle-
mount style Metz flash unit via the Metz SCA 3952 TTLAdapter. Maximum flash sync speed is
1/125 sec., making daytime synchronization possible.
When taking photos using infrared film, the position at which the subject is in focus is
slightly different than that of regular film. This is because the infrared rays have a longer
wavelength and the image converges behind the film plane of regular film. Use the pro-
cedure described below when taking photos using infrared film.
1. Set the focus as usual. Read the point on the distance scale matching the center
index of the depth scale.
The ISO of the flash is automatically set through the TTL connection from the camera's Film
Magazine; any adjustment to this is instantly recognized after the setting is locked and the
shutter release is half-pressed. Also, when Film Magazines with different ISO settings are
switched on the camera body, the TTL flash connection instantly recognizes the change.
2. Set the focus mode selector lever to “M” (manual focus mode). Turn the focusing ring
clockwise and align the read point to the infrared index.
To utilize the TTL flash feature with all TTL-operable Metz flash units, a Metz SCA3952 Mod-
ule is required. Please see the chart below for compatibility and/or additional adapters that
may be necessary.

Metz Flash SCA3952 System Functions
For example:
Charging completed
When charging of the flash is completed, a charging completed flash
(1) When the size of the subject you want to light with the flash is relatively small within the
picture
(2) When the background behind the subject is extremely bright or when there is a strongly
reflective object in the background
(3) When the background behind the subject is extremely dark (outdoors at night, etc.)
(4) For flash photography with a narrow film latitude
indicator in viewfinder icon will illuminate in the viewfinder’s liquid crystal display panel.
When exposure mode is set at “Av” or “P”, the shutter speed will be

1. While in the P or Av modes, the camera can be set to release the
shutter at the metered value, even if the background behind the
subject is dark.

Rear Curtain Sync Mode
When a moving subject has been shot under this function, the flash of light appears after
the moving subject.
The film sensitivity data, exposure compensation data and aperture
data are sent from the camera to the flash.
Data transfer
★ When using an SCA300 system flash (Metz 60CT-4, 45CL-4, etc.), use the SCA3000C
converter (sold separately).
★ For details, refer to the operating instructions of the flash and the SCA adapter.
★ To use the guide number indicated on the flash fully, wait several seconds after the
charging completed indicator lights.
★ Cautions on using instant film
Instant films (Polaroid 100-600 series and Fuji FP series), have a lower reflectivity
rate than regular film. Exposure compensation is necessary when using the flash in
the TTL mode.
In general, set the exposure compensation to about minus 1 or 1 1/3 EV.

Common Sense Camera Care and Practice
Maintenance and check of the camera
After-Sale Servicing
• Read instructions before using camera.
• Protect camera against shocks and falls. Use the neck strap supplied with it, when-
ever possible.
Be sure to read the terms and conditions in the warranty card.
1. For inquiries, opinions or questions concerning the product, please contact your near-
est Mamiya agent or service center.
• Check the batteries frequently and always carry spares. The sealed batteries supplied
with the camera may have been subject to storage conditions which have reduced its
service life.
• Be sure to wipe battery contacts before installation and watch correct polarity.
• Battery life differs, depending on frequency of use, type, age, storage condition, ambi-
ent temperature (use External Battery Case in very cold weather), etc.
• Always remove the battery (and film) when camera is not used for a long period of
time.
2. Servicing after the expiration of the period specified in the warranty card will be charged
to the user. The freight and transport costs should always be paid by the user.
3. The servicing parts for use in repair of the product will be retained at the factory for ten
years from the date of discontinuation of production.
Servicing is available for the same period as the servicing part retention period. As
the product may be serviceable even after this period, please consult your dealer or
nearest Mamiya service center for its serviceability.
• Always keep covers on lenses and camera body.
• Do not store the camera at temperatures exceeding 40˚C (105˚F) and -10˚C (15˚F).
Also avoid humid or sea air environment.
• Prolonged disuse shortens camera life. Periodically exercise the shutter (at different
speeds), lens diaphragms (at different apertures) and focusing mechanism.
• Protect camera against rain and moisture.
Servicing of malfunction or damage due to dropping, impact, fire, flood, etc.
1) The degree of such a malfunction or damage will be judged by the Mamiya service
department.
2) Such a malfunction or damage will be classified either non-serviceable or serviceable.
When the product is classified to be serviceable, it will be repaired at the expense of
the user, even if the malfunction or damage occurred within the warranty period.
• Do not touch lens surfaces. Use blower or lens tissue to remove dust particles.
• Always test your equipment before going on important assignments.
The Importance of Proper Maintenance
Your camera has mechanisms like film transport, shutter and diaphragm blades etc.
They are controlled by gears, levers, springs, and so on. All require special lubrication
from time to time. Ambient conditions can also affect these mechanisms, as well as the
electronic components and the optical glass of your lenses. We therefore suggest that
you have your camera and lenses checked, and if necessary serviced, periodically.
Specifications and appearance are subject to change without notice.
