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.

Diopter Adjustment

Look through the viewfinder and make sure that the focus frame (Rectangle with Circle) is in sharp focus. If it is not, turn the diopter adjustment dial in the "-" direction if you are nearsighted, in the "+" direction if you are farsighted. If this is not sufficient you may require an optional diopter corrected lens. See below.
Replacing the diopter corrected lens
1. Remove the lens supplied with the finder by pulling it downward.
2. Push the replacement diopter corrected lens upward into the viewfinder's eyepiece frame until it clicks into place. *Point the camera at a bright, plain object such as a white wall when making this adjustment.
Range of adjustment of diopter corrected lenses (Optional accessory) *If there is dirt or dust on the lens surface, remove it with a blower or sweep it off gently with a lens brush. *If there are fingerprints or dirt on the lens surface, wipe it off with a piece of clean, soft gauze. *Using solvents could discolor the diopter corrected lens frame.
Attaching/Removing the Lens

Attaching

1. Remove the camera's lens opening cap, just like you would remove a lens, by pushing the lens release button A backward and then turn the lens cap or the lens itself counter clockwise and lift out.

Removing

While pushing the lens release button A, rotate the lens counter clockwise until it stops and lift it off.

1. Open the back cover.

While holding down the magazine's back cover lock release button A push the back cover release button B to open the back cover.
2. Remove the roll-film insert.
Squeeze the release latches C of the roll-film insert in the film chamber with your fingers and take the roll-film insert out. 2. Half-press the shutter release button. The focus is adjusted automatically.

3. Remove the film.

Flip the roll-film clip's spool clip "SPL" away from the spool, and take out the film roll.
4. Fasten the film with a sticker.
After unloading the film roll, attach the provided sticker onto it to prevent unrolling.
*Move the empty spool from the top (FILM) to the lower take-up compartment (SPL), ready for loading the next film roll.
When the focus mark G lights.The picture is focused.
3. When G lights, press the shutter release button to make exposure(s). Defocusing Marks Flashing: The picture is not focused and the shutter cannot be released. Either press the shutter release button again to adjust the focus or move the camera to change the position of the focus frame.
Precautions for Film Unloading Do not unload an exposed film in direct sunlight. The exposed film should promptly be put in a light tight bag or box and sent to
the processing lab as soon as possible. Never try to remove the magazine from the camera body in the middle of film winding. Otherwise malfunction will result.
Removing a partially exposed film roll
To remove partially exposed film roll, insert the dark slide in the magazine and press the shutter button and the forced film advance button A simultaneously. This causes the film to be taken up till the end and the magazine's LCD panel shows "End".

6-exposure film

If you continue photographing after the 8th exposure when using 6-exposure film, the shutter membrane may be damaged by the leader paper at the film end or by the film's sticker. Use the procedure described below. Photograph in the same way as with 120 film. Eight exposures can be taken. After taking the 8th exposure, insert the dark slide in the magazine, then half-press the shutter release button while pressing in the forced film advance button to wind up the film.

This camera is equipped with a TTL phase difference detection type auto focus function. When the brightness or contrast is low and it is difficult to focus, a supplemental infrared light is emitted automatically. Set the focus mode selector lever to "S" (single focus mode) or "C" (continuous focus mode).

Single Focus Mode (S)

This mode uses the focus priority mechanism. The shutter can be released when the focus mark in the viewfinder is lit. This mode is suited for still subjects. The focus is locked when the G focus mark lights in the viewfinder's LCD. *The shutter cannot be released if the subject is not in focus (if the G focus mark does not light). *To take another photo with a different composition, take your finger off the shutter release button then press the shutter release button again.

Manual Focus Mode (M)

The auto focus function can be turned off so the focus can be adjusted manually.
1. Set the focus mode selector lever to "M" (manual focus mode).
Turn the focus mode selector lever to "M" (manual focus mode). M.F. appears on the main LCD panel liquid crystal display panel.
Continuous Focus Mode (C)
This mode uses the release priority mechanism. The shutter can be released regardless of whether the G focus mark in the viewfinder's LCD is lit. The focus is adjusted continuously while the shutter release button is half-pressed. This mode is suited for moving subjects. *The focus is not locked even if the G focus mark is lit. *The shutter can be released even if the G focus mark is not lit.

2. Adjust the focus.

Turn the lens focusing ring A and adjust the focus to the subject. When the subject is in focus, the G focus mark lights on the viewfinder's LCD.
Manual focusing using the focus mark. (Focus confirmation method) With this camera, a focus mark G lights in the viewfinder's LCD when the picture is in
focus. With the shutter release button half-pressed, turn the lens focusing ring to focus on the subject. When the subject is in focus, the G focus mark lights in the viewfinder's LCD.
Subjects With Which Auto Focusing May Not Work
The auto focus function requires subject contrast. Auto focusing may not be possible with the types of subjects described below. If this is the case, either switch to the manual focus mode and focus manually or point the camera at an object the same distance as the object you want to photograph, lock the focus using the focus lock mechanism, then take the picture. (See next page)

When differences between light
In focus and shade are not clear (blue skies, white walls and other objects with no contrast)
Turn the focusing ring clockwise.
Turn the focusing ring counterclockwise.
*Use this method when shooting in the manual focus mode and when using the M645 lenses. This method can be used when the lens aperture is f/5.6 or larger.
Subjects with continuous repeated patterns (building exteriors, blinds, etc.)
Brightly shining subjects like
the sun or light sources or objects in which these are reflected (car bodies, water surfaces, etc.)
When the object on which you want to focus is far smaller than the

focus frame

Using the Focus Lock Function
If the object on which you want to focus is not in the focus frame, the camera focuses on the background at the middle. In such cases use the focus lock mechanism to lock the focus before taking the picture.
AF Supplemental Infrared Light
When the subject is dark or the contrast is low and the camera is having trouble focusing automatically, a red lamp may light on the front of the camera when the shutter release button is half-pressed. This is a supplemental light that assists the camera's auto focus function.
1. Set the focus mode selector lever to "S".
*The AF supplemental infrared light is only emitted when the focus mode is set to "S" (single focus mode). *The AF supplemental infrared light's reach is limited. It does not reach distant subjects. Range: 9 meters (when using an 80mm f/2.8 lens) *When using a bellows lens hood (sold separately) with a diameter larger than that of the lens, focus before mounting the hood.
2. Change the composition.
With the shutter release button half-pressed, move the camera to achieve the desired composition, then release the shutter.

Camera Operation Test

This is a simple way to test the camera and autofocus without film. "P" Mode is the easiest. You may use any mode but "T".
1. Set the shutter release mode selector lever to "S" (to turn the power on). 2. Remove the Dark Slide from the magazine.
3. Open the back cover. 4. Set the autofocus modeselector lever to "S". 5. Release the shutter.

(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.
lf a polarizing filter is necessary, use a circular polarizing filter. A linear polarizing filter is not compatible with the Mamiya 645 AF and its operations.
Single-Frame Mode/Continuous Mode

Single-Frame Mode

The film is advanced one frame at a time each time the shutter release button is pressed. Set the shutter release mode selector lever to "S".

Continuous Mode

Photographs are taken continuously as long as the shutter release button is pressed. Set the shutter release mode selector lever to "C". Photographs are taken continuously at a rate of about 1.2 frames per second. If you reach the end of the film when shooting in the continuous mode, "End" flashes on the Magazine LCD panel.
The mode setting button can be used to set three modes: the auto bracketing mode, the multiple exposure mode and the self timer mode. NOTE: Each of these modes can be used independently. You cannot use these modes simultaneously.

Auto Bracketing Mode

In situations which are difficult to confidently meter for exposure, use the Auto Bracketing function. In this mode, three frames are taken successively with different exposures set automatically (overexposure, standard and underexposure). 1. Turn the mode setting dial and select "P", "Av" or "Tv". 2. Press the mode setting button A once to set the auto bracketing mode. *In the auto bracketing mode, three photos are taken in succession. Be sure to fix the camera in place, for example by using a tripod.
Automatic exposure operation in the auto bracketing mode

*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

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.

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.
