Advanced Photography and Various Functions
This chapter describes various functions of the camera.

Focus Modes

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. Focus is locked when the focus mark lights in the viewfinders LCD.
The shutter cannot be released if the subject is not in focus (if the 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.

Focus Area

With this camera, you can select the focus area that best suits the kind of pictures you intend to take. The selected focus area can be checked on the external LCD panel.

Selecting the focus area

1. When focus point selector button A is pressed for 1 second, the focus point selection mark appears on the display.

Average/spot auto exposure metering
The time used for the metering timer can be changed. Custom settings (C-04 on page 93)
Center-weighted average/spot exposure metering
Center spot exposure metering
The brightness of an area equivalent to 7.6% at screen center is measured, and the exposure is determined. The circle at screen center serves as a general guideline. This mode is suited to measuring subjects with strong contrasts or measuring only screen portions.

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 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. 1. When exposure compensation button A is pressed, appears on the external LCD. When the front or rear dial is turned counterclockwise, the exposure is increased; conversely, when it is turned clockwise, it is decreased. The exposure compensation value can be checked on the external LCD or LCD inside the viewfinder. 2. After taking the pictures, press exposure compensation button A again to return the exposure compensation value to 0. The exposure compensation value mark on the external LCD is cleared, and the exposure compensation function is released.

Custom settings (C-01 on page 93). 2. The maximum exposure compensation step can be changed to Custom settings (C-05 on page 93).

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. 1. Turn the shutter release mode selector lever to S or C.
Metered-value difference indicator
Keep pressing the AEL button A, and the difference between the metered exposure value and the exposure of the new composition will be displayed on the viewfinder LCD. This function can be used to see if an object of very different brightness levels can be properly photographed.

Multiple Exposure Mode (continued)
How to set the number of multiple exposures for shooting in multiple exposure mode
When "1. Number of multiple exposures" is selected using custom setting C-32, multiple exposure pictures can be taken for the number of multiple exposures selected. 1. Set to the multiple exposure mode by holding down the multiple exposure mode button A. The multiple exposure mode mark and the number of multiple exposure 0 are displayed on the external LCD. 2. Set the number of multiple exposures by turning the front or rear dial. Any number from two to six multiple exposures can be set. The selected number is entered by pressing SET button A or the multiple exposure mode button or after 5 seconds have passed. 3. Press the shutter release button. Multiple exposures are made on the same frame. After completing the required multipie exposure, the multipie exposure mode is automatically cancelled.
To cancel the Multiple Exposure Mode
Make sure to pull the dark slide out. Then hold the emergency film winding button C while halfpressing the shutter release button. The camera advances the film one frame and then exits from the multiple exposure mode.
When the dark slide is inserted into the Magazine, the film will automatically wind up. If the film holder is detached in the middle of multiple exposure, -no- will blink on the top LCD for 3 seconds. The multiple exposure mode is now cancelled. However, as the the film holder is still in the multiple exposure mode, the camera will resume the multiple exposure mode when the same film holder is attached. The multiple exposure mark will blink on the LCD, and number of the remaining exposure will be automatically set at 1.

Flash Photography (continued) / Rear Curtain Sync Mode
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 film latitude

Common Sense Camera Care and Practice
Maintenance and check of the camera
Read instructions before using camera. Protect camera against shocks and falls. Use the neck strap supplied with it, whenever possible. 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, ambient 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. 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 (at different apertures) and focusing mechanism. 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.

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.

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.

Holding the Camera

Grasp the camera firmly when taking photos. If the camera moves during exposure, the picture will be out of focus. *Grasp the grip firmly, tuck in both elbows and support the bottom of the camera with your left hand. *At slow shutter speeds, or when using the self timer, it is best to use a tripod and cable release or electromagnetic cable release (Optional accessories).
Taking Photos in the Full Automatic Mode
1. Set the shutter release mode selector lever to "S" (single-frame advance mode).
There are two shutter release modes: "S" (singleframe advance mode) and "C" (continuous advance mode). (See page 47.) When set to "L", the power is turned off.
3. Set the exposure mode selector dial to "P" (program auto exposure).
There are four exposure modes: "P" (program AE), "Av" (aperture priority AE), "Tv" (shutter priority AE) and "M" (manual mode).
2. Set the focus mode selector lever to "S" (single focus mode). (This control is located at the lower left front of the camera.)
There are three focus modes: "S" (single focus mode), "C" (continuous focus mode) and "M" (manual focus mode).
4. Set the exposure metering mode selector lever to "A-S" (average/spot auto switching).
There are three exposure metering modes: "A" in which the average light of the entire picture is measured with emphasis on the center of the picture, "S" in which the light in a spot at the center of the picture is measured, and "A-S" which combines these two to automatically switch the mode according to the extent of difference between the brightness of the light metered in the two modes and sets the distribution ratio of the exposure metering modes within an intermediate range. (See page 45.)

5. Focus.

1. Aim the camera so that the subject is within the focus frame
6. Unloading the exposed film.
When the fixed number of exposures have been taken, the camera automatically takes up the film till the end and stops. The LCD panel on the magazine should display End now.

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.
This camera offers you a selection of four exposure modes program AE (automatic exposure), aperture priority AE, shutter priority AE and the manual mode.

Program AE (P)

The aperture and shutter speed are determined automatically for the optimum exposure, according to the existing ambient light. This mode is best suited for general photography, allowing the user freedom to concentrate on the subject. Turn the exposure mode setting dial and set it to "P" (program 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.

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.

2. Turn the front or rear dial to set the desired shutter speed. The shutter speed value is adjusted in 1/2 stop increments.
2. Turn the rear dial to set the desired aperture. The aperture value is adjusted in 1/2 stop increments. 3. Turn the front dial to set the desired shutter speed. The shutter speed value is adjusted in 1/2 stop increments.
*The aperture 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 shutter speed value by turning the front or rear dial until the aperture value stops flashing and remains lit.
4. When the shutter release button is halfpressed, the difference between the manual settings and the metered value is displayed in the viewfinder's LCD panel. The value is displayed in 1/3 stop increments within a range of 6 EV. *For example, "+2.3" indicates +21/3EV, "-5.7" indicates -5 2/3 EV. *If the manual settings and the metered value are the same, nothing is displayed as a difference in the viewfinder's LCD panel.
*If the difference between the manual setting and the metered value is greater than 6 EV, "-u-" (under) or "-o-" (over) flashes in the viewfinder's LCD panel. *Exposure compensation cannot be used while in the manual mode. *When the difference between the manual setting and the metered value is displayed in the viewfinder's LCD panel while in the manual mode and the exposure compensation dial is set to a position other than "0", the value displayed is the difference between the manual setting and the metered value plus the exposure compensation value. This has no effect on the exposure.

X Mode (X)

This mode fixes shutter speed at the sync speed of 1/125 sec. In this position, the dials lock and cannot be rotated. (See pages 63-65.)

Time Mode (T)

This is a mechanically controlled mode for long exposures. It consumes no battery power. (See pages 55-56.) *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.
There are three exposure metering modes: "A" in which the average light of the entire picture area is measured with emphasis on the center, "S" in which the light in a spot at the center of the picture area is measured, and "A-S" which combines these two to automatically switch the mode according to the extent of difference between the brightness of the light metered in the two modes. The distribution ratio of the exposure metering modes is set within an intermediate range. See pages 45-46 for Exposure Metering modes. See page 47 for Film Advance modes.

Infrared Photography

When taking photos using infrared film, the position at which the subject is in focus is slightly different from during normal photography. This is because the infrared rays have a longer wavelength and the image converges further back than normal. Use the procedure described below when taking photos using infrared film. 1. Set the focus as usual. Find the point on the distance scale matching the subject depth scale's central index. 2. Set the focus mode selector lever to "M" (manual focus mode). Turn the focusing ring clockwise and set the distance scale to the above infrared index.
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

Depth of Field Preview/Eyepiece Shutter
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.
