Congratulations on your purchase of the Mamiya 645 AF Camera.
Mamiya pioneered the 645 SLR system camera three decades ago and the Mamiya 645 AF, with its TTL auto-focus, auto-exposure, auto-flash and autofilm winding features, is the latest Mamiya master piece and reflects its long tradition of medium format camera expertise.
Special Advice To Professional Photographers
Your Mamiya 645 AF 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 moisture. If cameras had odometers like automobiles, it would be easier to specify servicing schedules. 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.
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 controls, LCD displays and is ready for the age of digital photography.
Its high-tech focal plane shutter with speeds to 1/4000 sec. permits sync flash 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 magnesium housing, and also the Power Drive Grip, are now integral components of the diecast 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.
In order to acquaint yourself with the functions of the camera, you will want to practice without film. Please see bottom of page 37 how the camera can be tested without film.

This section describes basic camera operations, how to load film and basic full automatic photography. When we refer to "left or right" we assume you are holding the camera in shooting position.

Inserting the Batteries

(The camera will not operate without batteries)
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.
Set the shutter release mode selector lever to "L" (to turn the power off). Use six "AA" alkaline and lithium batteries.
1. Lift the battery case lock lever, turn it counter clockwise and pull out the battery holder. The batteries are sufficiently charged.
There is little power remaining. Have new batteries on hand. Camera will still operate. 2. Insert fresh batteries with the + and - ends as shown in the drawing.
Be sure the batteries are placed with

To remove the front lens cap, squeeze the shiny sections together and lift out.
*After removing the lens from the camera body, protect both ends by attaching the caps. *Oil, dust, fingerprints or water on the electronic contacts could result in malfunction or corrosion. Wipe such impurities off with a clean piece of cloth.
To remove rear lens cap turn it counter clockwise.

2. Attaching the lens

Align the red alignment dot of the lens (on the shiny flange) with the camera's red dot, fit the lens into the camera and rotate it clockwise until it clicks into place. *Do not touch the distance ring or other rotating parts during the auto focus operation.
Installing the Battery in the Magazine
The button battery supplies power to the magazine's LCD when it is detached from the camera. When it is attached the power is supplied by the camera's batteries.

Setting the Film Speed

The film speed (ISO sensitivity value) is the reference for all exposure and must be set correctly. If the set value differs from the actual value of the film in use, under- or overexposure may occur.
1. Remove the battery compartment cover screw.
Use a coin or suitable screw driver and turn it counter clockwise.
1. Press the L (up) button.
When the LCD panel displays information, press and hold the L (up) button on the bottom part of the LCD for more than 1 second. The ISO indicator will blink.

2. Insert a battery.

Insert the battery according to the polarity indication + in the battery compartment, and close the battery cover. Battery used: Sony CR2032 or equivalent

2. Set the film speed.

Set the film speed of the film by pressing the L (up) or M (down) button. To lock the speed setting, press and hold the two buttons simultaneously for more than one second; the film speed will be written in memory in 5 seconds.
Be sure to watch correct polarity
*When the battery is exhausted, remove it immediately and replace with a new battery. Otherwise accidental battery fluid leakage may damage the contacts.
*The setting is not complete while the ISO indicator is blinking. *The information on the film in use, such as the type, ISO sensitivity value and number of exposures, is stored in the back -up memory. However, when the battery capacity has dropped during stand-alone use of the magazine, the information may not be shown by the LCD panel. *The information on the film (type, ISO sensitivity and number of exposures) is stored in the memory, but when the battery power is low this information may be displayed erroneously. Be sure to replace the batteries with new ones.

Attaching/Detaching the Magazine
When there are no batteries in the camera, the shutter's "Safety Retraction" feature, keeps it in the open position and the magazine's dark slide cannot be pulled out, even when it is attached to the camera. Film winding and shutter release are also blocked in this case.

Detaching

1. Insert the dark slide into the magazine.
1. Remove the camera's rear body cap and the magazine's protection cap.
2. With your thumb first push button A down and then simultaneously button B in. The magazine will separate itself from the camera body. 2. Fit the body coupler of the magazine into the bottom channel of the camera, properly centered. 3. Push the magazine against the camera body until it snaps into place. (You will instantly hear the shutter closing) *When the magazine is removed, the shutter will automatically open, as explained on the previous page, under "Shutter Safety Retraction" Film winding and shutter release are also locked.
Shutter Safety Retraction
The precision shutter blades are made of very thin hyper-duraluminum and could be damaged if unprotected. Therefore the camera is designed to automatically retract the shutter into the open position when the magazine is removed. When it is reattached the shutter automatically closes and is ready for normal function. (Batteries must be in camera).
The magazine cannot be attached or detached unless the dark slide is in place.
Automatic film advance to #1
There is no need to line up the film's paper leader start mark. The magazine automatically advances the film to the first frame (See page 22).
Loading Film in the Magazine
1. Open the back cover of the magazine.
By first pushing the button A down and then button B simultaneously.
4. Attach an empty spool to the roll-film insert.
Flip the roll-film insert's lower spool clip "SPL" away from the spool, fit an empty spool between takeup spool studs E, and return the spool clip "SPL" to the original position.
2. Take out the roll-film insert.
Squeeze the center block "645" C between your fingers and pull it out.

5. Set the film.

Flip the roll-film insert's upper spool clip "FILM" away from the spool, fit a roll of film as shown in the illustration, and return the spool clip "FILM" to the original position.

When you load film for the first time, remove
and discard the protective paper cover which is attached to the film rails in the magazine.
3. Set the film type (120 or 220).
Push and hold the pressure shaft D located under the 645 center block. This frees the pressure plate and permits it to be turned and set for either 120 or 220 film.
Be sure to align the lock pins with the holes on
the pressure plate. The film type should be displayed when the film is loaded on the LCD of the magazine.
6. Attach the leader paper of the film to the empty spool.
Gently pull out some of the leader paper, insert the tip of the leader paper into the take-up slot of the empty spool, and rotate the spool a few times to wrap the leader tape around it.
When the pressure plate (120/220) is set erroneously:
Shutter Release Button/Holding the Camera
7. Insert the loaded film insert into the magazine.
While squeezing the center latches together, place the film insert, with the feed spool on top, in the magazine and with pressure on the left and right blocks G push it into proper position. (You will hear a click).

Shutter Release Button

The shutter release button has a two-step action, A half-press (light pressure) will activate the camera, heavier pressure will release the shutter. When pressed lightly it stops at a certain point. In this manual this position is called the "half-press" position. When half-pressed, the power turns on and the camera becomes functional.

8. Close the back cover.

Push in the upper part of the back cover firmly to close it. 9. After attaching the magazine onto the camera body, pull out the dark slide and press the shutter button halfway; this will feed the film automatically to frame No. 1. Place the dark slide in the magazine's rear storage pocket *It is not required to align the film start mark, for the magazine will automatically detect film frame No. 1 from any position. *When the magazine is mounted on the camera body, the mirror and shutter which has been freed will be set in position. *Do not wrap too much leader paper around the empty spool. Otherwise the film section may be exposed to light. *When the magazine is separated from the camera, the power save mode is activated in 5 seconds after the start of stand-alone operation and the LCD panel turns off. To release the power save mode and turn on the LCD panel, press the L (up) button. *To prevent accidental film fogging, do not pull out the leader paper too far or load/unload film under direct sunlight. *When the film is not wound properly, the counter display disappears and the --" mark appears in the LCD.

Aperture Priority AE

Set the desired aperture and the camera selects the optimum shutter speed accordingly. Use the Av mode to maintain specific control over depth of field, i.e. taking portraits or landscapes. 1. Turn the exposure mode setting dial and set it to "Av" (aperture priority AE).
* In the "X" exposure mode the lock function is activated. Press the exposure mode dial lock release button while turning the exposure mode setting dial.

Shifting the Program

Use "PL to record subjects with depth using a smaller aperture (landscapes, etc.), "PH" to record moving subjects with a high shutter speed. Turn the front or rear dial to shift the shutter speed between the +1.0 EV high speed side "PH" and -1.0 EV low speed side "PL". PL =Program Low / slower (low) shutter speeds PH= Program High / faster (high) shutter speeds
2. Turn the front or rear dial to set the desired aperture. The aperture value is adjusted in 1/2 stop increments.
*If the aperture flashes on the main LCD and in the viewfinder display when the program is shifted, the proper exposure cannot be achieved. Please select a different Program mode. * When the Program mode is shifted, the aperture changes along with the shutter speed to maintain the proper exposure.
*The shutter speed value on the main LCD and in the viewfinder display will flash when photographing objects that are too bright or too dark for proper exposure. The proper exposure cannot be achieved at the present settings. Change the aperture value by turning the front or rear dial until the shutter speed value stops flashing and remains lit.

Shutter Priority AE

Set the desired shutter speed and the camera selects the optimum aperture accordingly. Use the Tv mode to maintain specific control over action, i.e. shooting sporting events or deliberately blurring your subject. 1. Turn the exposure mode setting dial and set it to "Tv" (shutter priority AE). *In the "X" exposure mode the lock function is activated. Press the exposure mode dial lock release button while turning the exposure mode setting dial.

Manual Mode (M)

Use the manual mode "M" when you desire to have complete control over shutter speed and aperture settings. This mode is also best utilized in combination with an independent hand-held exposure meter. 1. Turn the exposure mode setting dial and set it to "M" (manual mode). *In the "X" exposure mode the lock function is activated. Press the exposure mode dial lock release button while turning the exposure mode setting dial.

Exposure Compensation

Average Exposure Metering Mode (A)
(Set the exposure metering mode selector lever to "A".) The average light of the entire picture area is measured, with emphasis on the center. 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 or white, the resulting photograph may be under- or overexposed. When this occurs, use the exposure compensation function. Exposure compensation can also be used when you want to intentionally create overexposed or underexposed pictures. Turn the exposure compensation dial while pressing the exposure compensation dial lock release button A located on the right side of the viewfinder. The exposure can be adjusted within a range of 3 EV in 1/3 steps. Be sure to set the exposure compensation dial back to the "0" position once you are finished taking photos with exposure compensation.
Spot Exposure Metering Mode (S)
(Set the exposure metering mode selector lever to "S".) The light in the circle at the center of the picture area is measured to determine the exposure. This mode is best suited for strongly backlit subjects, or when you desire to measure a specific area. When the spot you want to measure is not at the center of the picture, use the AE lock function. (See pages 57-58 AE Lock Mode.)
Display of the exposure compensation in the viewfinder's LCD panel
Average/Spot Auto Switching Exposure Metering Mode (A-S AUTO)
(Set the exposure metering mode selector lever to "A-S".) With the A-S metering mode, average or spot exposure metering is selected automatically and the appropriate exposure is set accordingly. The spot mode is selected automatically when the brightness within the spot metering area is lower than the brightness of the average metering area by about 1.5 EV or greater. The average mode is selected when the spot exposure metering value is the same or brighter than the average value. When the difference between the spot value and average value is between 0.75 and 1.5 EV, the appropriate exposure is achieved at an intermediate value.

Self Timer Mode

With this function, under the default setting the shutter is released 10 seconds after the shutter release button is pressed. The self timer lamp flashes slowly for the first 7 seconds, then flashes quickly for the last 3 seconds before the shutter is released. Use this function to take group photos or to photograph yourself. 1. Fix the camera to a tripod. 2. Press the mode setting button A three times to set the self timer mode.
3. The number of seconds before the shutter is released can be changed by turning the front or rear dial. The number of seconds can be set between 3 and 60, in steps of 1 second from 3 to 10 seconds, in steps of 10 seconds from 10 to 60. The setting is registered after 5 seconds or when the shutter release button is pressed. 4. Looking through the viewfinder, determine the composition, check that the focus is set properly, then press the shutter release button. The shutter is released after the set number of seconds. * To cancel the self timer mode after pressing the shutter release button, either press the mode setting button A or turn the exposure mode setting dial. Changing the exposure mode does not change the set self timer operating time. *If there is a bright light source behind the camera or if the shutter release button is pressed without looking through the viewfinder, light enters the viewfinder's eyepiece, affecting exposure metering. Turn the eyepiece shutter open/close dial to close the eyepiece shutter. *When the shutter release mode is set to "C" (continuous advance mode), the self timer mode can be used to take photos at intervals of 3 to 60 seconds while the shutter release button is pressed. *To cancel the self timer mode, press the mode setting button A once. The self timer mode is canceled and the camera is reset to the normal shooting mode. *When the shutter release mode selector lever is set to "L" (power off), all the settings aside from the selected mode are reset to the default values.

Extended Exposure Modes

(Bulb and Time Modes)
*To prevent the camera from moving, use both an electromagnetic cable release (sold separately) and a tripod. *When the BL (Backlight) button A is pressed, the main LCD panel and the magazine LCD panel light for about 10 seconds. This makes the liquid crystal display panels easier to view in dark places, for example when photographing night views. *In the "X" exposure mode the lock function is activated. To set a different mode, press the exposure mode dial lock release button B while turning the exposure mode setting dial.

When the aperture is large (the subject depth is small)
When the aperture is small (the subject depth is large)
*Use a red filter when taking photos using infrared film. *Be sure to read the infrared film's usage instructions.

Flash Photography

In addition to its standard flash sync system, the Mamiya 645 AF features TTL (through the lens), off the film (OTF), electronic flash exposure automation. 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 AF's dedicated hot-shoe to a shoe- or handle-mount style Metz flash unit via the Metz SCA 3951 TTL Adapter. Maximum flash sync speed is 1/125 sec., making daytime syncronization possible. 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. To utilize the TTL flash feature with all TTL-operable Metz flash units, a Metz SCA 3951 Module is required. Please see chart below for compatibility and/or additional adapters that may be necessary. The resulting flash exposure automation determines correct flash exposure andautomatically adjusts the output of the flash. It also automatically corrects for exposure compensation normally required when using filters, close-up bellows or extension tubes. However as with all TTL systems, it requires manual compensation for differences in film surface reflection characteristics. The amount of compensation is determined by experimentation and is performed on the Mamiya 645 AF's Film Magazine ISO setting. 1. Mount the SCA3951 adapter onto the Metz flash, insert fully into the camera's hot shoe, then tighten with the fixing knob A 2. Set the exposure mode, then check the shutter speed and aperture. *The shutter cannot be released if the flash's OK lamp is lit. *When using an SCA300 system flash (Metz 60CT-4,45CL-4, etc.), also use the SCA3000C converter (sold separately). *For details, refer to the operating instructions of the flash and the adapter. *To use the guide number indicated on the flash fully, emit the flash several seconds after the charging completed indicator lights. *Cautions on using instant film Instant film (Polaroid 100-600 series and Fuji FP series), has a lower reflection rate than regular film. Exposure compensation is necessary when using the flash in the TTL mode. In general, set the exposure compensation to about 1 or 1 1/3 EV on the minus side. *With TTL flash photography, the reflection of the flash is metered and the intensity of the flash is adjusted automatically, so TTL flash photography is not necessarily suited to all conditions. In the cases described below, we recommend that you use a flash meter to check the intensity of the flash or to use a manual flash setting. For example: (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 latitude film

Flash Photography with Flashes other than Metz Flashes
1. Mount the flash onto a flash bracket or if it is a handle-mount style flash attach to the bottom of the camera. Do not attach a dedicated flash unit to the camera's hot shoe that is not designed specifically for the Mamiya 645AF. To use this type of flash, use a flash bracket or other means, and connect the synchro cord to the camera's synchro terminal. (See note below about flashes designed exclusively for other camera makes.) *Remove the rubber cover when connecting the synchro cord. After shooting, be sure to attach the rubber cover in order to protect the synchro terminal's contacts.
Depth of Field Preview Button
When the preview button is pressed in, the depth of field for the aperture set on the camera can be checked by looking through the viewfinder.
After focusing, press in the preview button.
When using auto focus, the aperture is set to the displayed aperture while the button is pressed and the focus is locked.

Eyepiece Shutter

2. Turn the exposure mode setting dial and set it to "X" (1/125 sec.) or "M" (manual). When "M" (manual) is selected, turn the front dial and set the shutter speed to 1/125 sec. or less. 3. Turn the rear dial to set the aperture, then take the picture. *This camera's synchro contact is an X contact. *When using MF or M grade flash bulbs, set the shutter speed to 1/30 sec. or less for MF grade flash bulbs, 1/15 sec. or less for M grade flash bulbs. Use this when there is a strong light source behind the camera or when pressing the shutter release button without looking through the viewfinder. (This prevents exposure error due to light entering from the viewfinder.)
Turn the eyepiece shutter lever in the direction of the arrow.
WARNING Using flashes designed exclusively for other makes of cameras may
damage the camera's internal mechanisms if connected to the camera's hotshoe. In this situation, use an off-camera flash bracket and connect a PC cord to the camera's synchro terminal. *When using flashes with a flash duration of 1/500 sec. or longer, set the shutter speed to 1/30 sec. or less.

Strap/Using a Tripod/Auxiliary Release Contact
Put the neck strap through the camera's strap mount as shown on the diagram and tighten it. For safety, check that the strap is securely fastened to the strap mount.

Common Sense Camera Care and Practice
The Mamiya 645 AF is a precision optical/mechanical instrument, built for heavy professional use and a long service life, if properly treated and maintained. Please observe these basic caveats: Read instructions before using camera. Protect camera against shocks and falls. Use the neck strap supplied with it, whenever possible.
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.

Batteries Care

Check the battery frequently and always carry spares. The sealed battery 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, ambient temperature (use External Battery Case in very cold weather), etc. Always remove the battery (and film) when camera is not used for a period of time. Always keep covers on lenses and camera body. Do not store the camera at temperatures exceeding 40C (105F) and -10C (15F). Also avoid humid or sea air environment. Prolonged disuse shortens camera life. Periodically exercise the shutter (at different speeds, lens diaphragms and focusing mounts. Protect camera against rain and moisture. Do not touch lens surfaces. Use blower or lens tissue to remove dust particles. Always test your equipment before going on important assignments. 4. Battery life differs, depending on type, age, storage condition, ambient temperature, frequency of use etc. 5. Be sure to match the poles of the battery with those shown in the diagram in the chamber. 6. Always keep batteries out of the reach of children and never throw used batteries into a fire or expose to excessive heat. 7. When going on trips be sure to carry spare batteries to ensure that the camera will function. Also, as batteries tend to temporarily malfunction at temperatures below freezing, when photographing in extremely cold climates, carry the External Battery Case. 8. When you carry spare batteries, leave them in the original factory packaging. If they are "unpackaged", be sure to wrap them carefully in order to prevent them touching each other or any metal objects which can cause them to short circuit and become useless. 1. The sealed, new battery which is supplied with this camera may have been subject to storage conditions which have reduced its service life. Therefore it is desirable to replace it with a fresh battery as soon as possible. 2. Carefully wipe the battery contacts before inserting into the chamber. Failure to do so may result in poor electrical contact and consequent malfunctioning of the camera. 3. Always remove battery when camera is not used for a while. Always carry spare batteries.

Battery Power / Battery Care

Battery power

The cameras power is turned on when the drive dial is set to S, C or M.UP In order to prevent. the cameras 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). Remaining battery The initial setting for the exposure metering charge display status maintenance period is 15 seconds. It can be changed at any time to a period within a 5- to 60second range using the custom settings. (C-04 on page 93) 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 cameras power is on.
1. Remove the battery compartment screw cap.
Use a coin or suitable screw driver and turn it counter clockwise.
2. Insert a battery. Insert the battery according to the polarity indication in the battery compartment, and close the battery cover. Battery used: Sony CR2032 or equivalent

Setting the Index Number

The index numbers are indicated in four digits (0000 to 9999).The index number is stored in the camera body so that when replacing a series of roll film holders, the camera will superimpose sequential index numbers on exposures. This is effective when exposing and managing a large number of rolls of different types of film. 1. Turn on the power. Set the shutter release mode selector lever to S or C.

F C X M

6. After the index number is specified, press the set button A for approximately one second to store the setting.
In the default setting the index number is not imprinted. Change the setting in C-02 of the custom setting mode (see page 93). If film is not loaded, the index number will not change. The starting index number can be set at will. For example, when shooting in different places or for different purposes, you can classify the photos by changing the starting number of any of the digits. Once the last three digits reach 9999, they will restart from 0000 and the thousands place will be increased by one. 0000 can also be set using the index number setting procedure. After 60 seconds, the index number setting mode is cancelled and the setting is not registered to the cameras memory unless the set button has been pressed. Custom settings remain in the memory even when the shutter release mode selector lever is set to L (turning the power off). When the exposure mode is not set to the CF position and you press the set button for approximately 2 seconds, you can check the index number for the next frame. Pressing the set button again will let you to check the month-date-year and hourminute settings.
