Congratulations on your purchase of the Mamiya 645 AFD III
Camera.

Mamiya pioneered the 645 SLR system camera three decades ago and the
Mamiya 645 AFDIII, with its TTL auto-focus, auto-exposure, auto-flash and
auto-film winding features is the latest Mamiya masterpiece and reflects its
long tradition of medium format camera expertise.
Combining 35mm handling ease and speed but with an image size almost 3
times larger, it is a full-featured camera, utilizing many digital controls and
LCD displays, deeming it appropriate for the age of digital photography.
Its high-tech focal plane shutter with speeds up to 1/4000 sec. permits flash
sync up to 1/125 sec. and has an exclusive "Safety Retraction" feature, which
protects it against accidental damage.
The AE Prism Finder with its many features, protected by a sturdy magne-
sium housing, and also the Power Drive Grip, are now integral components
of the die cast aluminum camera body, designed for heavy professional use.
All the many features, safety interlocks and other important information are
covered in detail in these instructions. It is imperative that you read them
thoroughly before you put your camera to work, in order to ensure proper
operation and maximum results.
Note:
In order to acquaint yourself with the functions of the camera, you will want to
practice without film. Please see the page 9 how the camera can be tested with-
out film.
Special Advice To Professional Photographers
Your Mamiya 645 AFDIII is designed for heavy professional use and will give you a long
service life if properly maintained. Your camera and lenses have many moving parts
which require periodic lubrication. Its electronic components, too, are subject to wear
and tear and are affected by ambient conditions like dust, sand, sea air, heat and mois-
ture.
If cameras had odometers like automobiles, it would be easier to specify servicing sched-
ules. May we suggest that if you shoot thousands of film rolls per year, you send your
equipment annually for servicing to the Mamiya distributor in your country.
Mamiya 645 AFDIII corresponds with digital backs compatible with MSCE (Mamiya Se-
rial Communication of External) system.

stall and remove the lens, and how to install and remove the
magazine.
Inserting the Batteries ( )
The camera will not operate
without batteries
Checking the Battery Power
Set the drive dial to “L” to turn off the power.
Use six “AA” alkaline or lithium batteries.
Set the drive dial to “S” to turn on the power.
Check the battery condition in the lower right corner of the main LCD.
1. Lift the battery case lock lever, turn it counter
clockwise and pull out the battery holder.
The batteries are sufficiently charged.

L
2. Install the batteries while ensuring their po-
larities are properly aligned with the
markings on the battery case.
and
■ Be sure the batteries are placed with proper
polarity
There is little power remaining. Have new batteries on hand.
Camera will still operate.
There is very little power remaining. Camera will stop
operating soon.
Flashing
★ Set the shutter release mode selector lever to “L”
(to turn the power off) and replace the batteries with
new ones.
Flashing
★ When the batteries are spent, “batt” flashes on the
main LCD and the viewfinder's LCD when the shut-
ter release button is pressed.
3. Return the battery holder to its case and lock it
by turning the lever clockwise. Make sure it is
firmly attached.
★ When replacing the batteries, be sure to use six new batteries of the same type. Do
not mix different types of batteries or old batteries with new ones.
Number of rolls that can be exposed with a new set of batteries
(under our test conditions)
At normal temperature (20˚C) (68˚F)
★ After inserting the batteries, set the date and time. (See page 23.)
Rechargeable nickel-metal hydride (Ni-MH) or nickel-cadmium (Ni-Cd)
batteries can be used.

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)
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
■ Be sure to insert the battery with the correct
polarity
★ When the magazine is installed onto the body, the power will be supplied to the maga-
zine from the camera body.
★ 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.
★ 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.
● 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.
Batteries Care
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.
3. It is advised to carry spare batteries in remote or foreign locations.
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.
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.
