Mamiya pioneered the 645 SLR system camera three decades ago and the
Mamiya 645 AFD , 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 with the advantages of an almost
3x larger image size, it is a full-featured camera, utilizing many digital con-
trols, LCD displays and is ready 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 bottom of page 11 how the camera can be tested
without film.
Special Advice To Professional Photographers
Your Mamiya 645 AFD 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 by the Mamiya distributor in your country.
Mamiya 645 AFD corresponds with digital backs compatible with MSC (Mamiya Serial
Communication of External) system.

Camera Operation Test
This is a simple way to test the camera and auto focus without film.
“P” Mode is the easiest.
You may use any mode but “CF”.
“A-S” Mode is the
easiest. You may
use any mode.
1. Set the shutter release mode se-
lector lever to “S” (to turn the
power on).
2. Remove the Dark Slide from the
magazine.
3. Open the back cover.
4. Set the auto focus mode selec-
tor lever to “S”.
5. Release the shutter.
The camera can be set to release the shutter when the back cover is closed.

Before Taking
Photographs
Preparation before
taking photographs
This chapter describes how to put in the batteries, how to in-
stall and remove the lens, and how to install and remove the
magazine.
The camera will not operate
Inserting the Batteries ( )
without batteries
Be sure to turn the switch of the Shutter Release Button to “L” as shown in the top
illustration, to turn the power off. This prevents electrical damage to the circuits.
Set the shutter release mode selector lever to “L” (to turn the power off).
Use six “AA” alkaline or lithium batteries.
1. Lift the battery case lock lever, turn it counter
clockwise and pull out the battery holder.
Checking the Battery Power
Set the shutter release mode selector lever to “S” (to turn the power on).
Check the battery condition in the lower right corner of the main LCD.
2. Insert fresh batteries with the
as shown in the drawing.

Be sure the batteries are placed with proper
polarity

The batteries are sufficiently charged.
There is little power remaining. Have new batteries
on hand.
Camera will still operate.
There is very little power remaining. Camera will not
operate.
Set the shutter release mode selector lever to “L”
(to turn the power off) and replace the batteries
with new ones.
When the batteries are spent, “batt” flashes on
the main LCD and the viewfinder's LCD when the
shutter 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.
After inserting the batteries, set the date and time. (See page 25.)

Installing the Battery in the Magazine
Batteries Care
1. Life of the batteries that come with the camera body is subject to storage conditions.
2. Bolts 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 when you travel where they may be difficult to
obtain.
4. Performance of the battery degrades in low temperature. Keep them warm when in
cold climate.
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. Keep the batteries out of the camera body, when it is not used for a long time. Leaving
them in the camera may cause corrosion.
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 warning labels of the batteries for handling of the batteries.
The button battery supplies power to the magazine's LCD when the film magazine is
detached from the camera. When the film magazine is attached to the camera body, it is
powered by the camera's batteries.
1. Remove the battery compartment
cover screw.
Use a coin or suitable screw driver and turn it
counter clockwise.
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 watch 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 battery is not equipped with a battery level indicator. When the maga-
zine LCD panel becomes dark or disappears, replace the battery. As a rough guide-
line, the battery should last approx. one year.
