Loading the Film

While pushing the Back Cover Lock Release Button @ downward, press the Back Cover Opening Button @I>, and the Back Cover will open.
While squeezing in on both sides of the Release Latch 8, pull the Roll Film Insert out of the camera body. At that time, move the empty spool in the upper part down to the lower spool compartment.
Align the right-hand side of this empty spool with the lower Spool Stud @ (convex). Slide the spool into position making sure that the left-side of the spool is properly held by the Spool Clip.
In the same manner, insert a roll of film in the upper compartment. At that time, check that the film leader paper is set as shown in the photo above. (The leader paper inside is facing outward on the pressure plate. Note that the film direction is wrong if the leader paper is facing inward.)

Pull out some of the leader paper. Insert the tip of the leader paper into the slot of the lower Take-up Spool.
Gently rotate the Take-up Spool in the direction of the arrow until the start mark of the leader paper is aligned with the start mark (A) on the Spool Clip. (Correctly align the start marks with each other, taking care that the film is not rolled excessively.)
Insertion of the Roll Film Insert

Memo Cllp

Insert the loaded Roll Film Insert straight into the holder as shown in the photo above. Be sure to check that the Roll Film Insert has been completely set before closing the Back Cover.
The Memo Clip on the Back Cover is used to hold the box top of the film in use or a piece of paper for storing necessary data.
There are two methods for advancing film to the first frame. In either case, when loading the film, always align the film with its start mark.
Film Advancing after the Roll Film Holder is mounted onto the Body: Make sure that the Multiple Exposure Lever @ is aligned with a white square dot. Wind the Wind-up Crank until it stops and the number 1 will appear in the Film Counter Window. The shutter is now cocked and the camera is ready for the first exposure.
Film Advancing by Film Advance Knob of the Roll Film Holder Check that the Dark Slide is completely inserted (light blocked). When the Film Advance Knob @ of the Roll Film Holder is rotated in the direction of the arrow until it stops, the camera will be ready for the first exposure. *It should be noted that when the Coupling Pin (refer to the manual for the Roll Film Holder) is depressed with the finger, the film will not stop at the first frame.

. Color Coding

The yellow 4 and 2 represent full seconds. and all other figures rep resent the denominator of a fraction. (Thus. 30 equals 1/30 sec.) The yellow B represents BULB. When the Shutter Speed Dial is set to B, the Shutter remains open as long as the Shutter Release Sutton is depressed. The red 60 (1/60 sec) represents the highest permissible shutter speed for electronic flash synchronization. The red 0 mark is the AE position. and 0 is the AE Lock position. These marks are used with the AE Prism Finder N. (When the Prism Finder N and Waist Level Finder N are attached, and the dial is set at 0 or 5. the effective shutter speed is 1/1000 sec). Set the Shutter Speed Dial only to the click stop position. Using an intermediate positions will result in inaccurate exposure.
Align your desired shutter speed with the white alignment index 8.

*In other than the 0 and 0 marks, the dial will rotate freely, and each shutter speed display will stop at the click point.
When selecting shutter speed settings other than the C* and R marks, release the lock by pushing the button @ in fomt of the dial. Turn the Shutter Speed Dial to your desired speed.
*As an accessory, Mamiya offers Diopter Correction Lenses which can be attached to the viewfinders. Near and farsighted persons will find these accessories useful for obtaining accurate focus. *The Focusing Screen is interchangeable. To change screens, refer to the instruction manual supplied with the screens.
While looking through the viewfinder, adjust the lens Focusing Ring until the most important part of the subject appears sharp and clear. Extremely accurate focusing is simplified by the split-image rangefinder spot located in the center of the Focusing Screen. (to use, match up the image on both sides of the split-image.)
The split-image rangefinder spot is surrounded by a microprism collar which fractures the image whenever it goes slightly out-of-focus. Consequently, this is an invaluable aid for pinpoint focusing accuracy. The outer ground glass ring (which encircles the microprism collar) can be also used for focusing.

AM (Auto/Manual) Lever

Set the desired f/stop on the Aperture Ring @ by aligning the f/number with the red reference dot @. (The Aperture Ring has a click stop for each f/stop. In-between clicks can also be used.)
1. In normal photography, set AM Lever so that character A is visible in the lever window. If you do so, the aperture will remain wide open, stopping the lens down only during shutter operation. 2. Moving the AM Lever of the lens so that M is visible will stop the lens down to the preselected aperture, thus making it possible to confirm effect of the aperture through the viewfinder.
1. The Shutter Release Button @ is a 2-step type. The release pressure will charge halfway through the cycle. The first step light up the metering related display. The second step is the electromagnetic shutter release position. (The first position operates only when the AE Prism Finder N is used.)
If the film is not completely advanced, the Dark Slide is not removed or the battery is exhausted, the shutter can not be released even when pushing the Shutter Release Button. After releasing the shutter, the Wind-up Crank is unlocked automatically, making it possible to transport the film to the next frame. *In normal photography, set the shutter Release Selctor @ to the NORMAL (white square) position. *Note: Always make sure that the Shutter Release Selector clicks into position. When the battery is exhausted during photography, and the shutter can not be released, set the selector to the yellow dot, and you will be able to use the mechanical shutter at 1/60 sec.

When this setting is used, the shutter speed is always 1/60 sec. regardless of the Shutter Speed Dial postion. When your camera is not in use, set the Shutter Release Selector to the red dot so that the power is turned OFF.
Attaching and Removing the Neck Strap to the Camera Eye-level Operation Waist-level Operation
Attaching it to the camera
1. Draw out the neck strap fastener 8-G the attaching clip while pushing it down.
2. Place the hole of the strap fastener @ over the lifting lug of camera body as illustrated, and pull until it clicks and locks into place.
No matter how carefully one focuses the camera, if there is camera movement during the instant that the shutter is released, sharp pictures are unlikely. To eliminate camera movement, care must be taken regarding the method of holding the camera and releasing the shutter.
Removing it from the camera
When hand-holding the camera with the Waist Level Finder attached, adjust the length of the neck strap to take out the slack and support the camera firmly against your body.
With your finger, pull the neck strap fastener @of attaching clip upward and push part (@ in the direction of the arrow. The strap can now removed. When attaching the strap to the lifting lug on the side of the camera with the Wind-up Crank, insert the neck strap fastener @ into the lower pad of the double solt.
3. Open the Back Cover, and remove the Roll Film Insert. The exposure counter will return to S (start) automatically. 4. Move the Spool Clip of the Roll Film Insert outward to remove the film. 5. Remove the film from the Roll Film Insert, exercising care that the film does not loosen, and seal it.
1. Turn the Wind-up Crank until it stops (one turn), and the camera is ready for the next exposure. 2. After the fixed number of exposures has been taken (15 for 120 film, 30 for 220 film), the Shutter Release Button automatically locks, and the Wind-up Crank becomes free. At that time, wind the Crank until the leader paper is completely wound onto the Take-up Spool. (By turning the crank 4 to 5 times after the final frame of the film comes in sight, the film will be wound up completely.)
Depth-of-field refers to the total area (foreground and background) which will appear in sharp focus. The area of sharpness (depth-of-field) depends upon the distance the lens is focused at, the f/stop (or aperture) being used, and the focal length of the lens. The area that will appear sharp can be determined as follows:

1. Depth-of-field can be determined by referring to the Depth-of-field Scale engraved on the lens. For example, with the 60mm f/2.8N lens focused at 10 ft. (3m) and the Aperture Ring set to f/22, the Depthof-field Scale reveals that everything from about 7ft. (2m) to about 20 ft. (6m) will appear sharp.
2. The lens can also be stopped down to the preselected aperture for direct viewing of the depth-of-field by using the AM Lever on the lens. To do so, move the lever so that M (manual) is visible. When the lens is set to M you can take a picture observing the depth-of-field in the finder.
The bracket o f a handle-mount flash unit can be attached to the cameras
tripod socket. A shoe-mount flash can be attached to the cameras Hot-shoe or the Hot-shoe of the Left Hand Grip. *The Mamiya M645 Super has an
(1) When using an electronic flash, plug the synchronization cord into the sync terminal and set the Shutter Speed Dial to 1/60 sec. or longer. Flash Synchronization Chart
When the Multiple Exposure Lever is aligned with MULTI, the doubleexposure prevention mechanism is disengaged, so that the shutter can be cocked (and even with the Wind-up Crank turned) without moving the film, making multiple exposures possible on tile same frame. (When making multiple exposures, the exposure counter will not advance., *Remember to return the lever to the white square mark position upon completion of the multiple exposure. If you forget to return the lever, multiple exposures will continue to occur on and the next frame.
using infrared film, it is necessary to make a focusing adjustment in order to achieve accurate focus. This is becuase the focus position of the image deviates from normal since the infrared ray wavelength is longer. Focusing Adjustment Procedure: 1. The red dot or line on the right side of the lens center reference line is the infrared mark. 2. After focusing in the usual manner, check the distance on the Distance Scale that is aligned with the center
reference mark of the lens. Make the focusing adjustement by turning the Focusing Ring slightly in the direction of the arrow in the accompanying photograph so that the distance just observed is aligned with the infrared mark. Focus is now correct for infrared and you can release the shutter. *For information regarding the proper filter and exposure, refer to the data sheet packed with the film. Always use the appropriate filter for the lens.

To take time exposures, set the Shutter Speed Dial to "B" and use a cable release with a lock provision. Inserting an optional Cable Release Adapter into the Auxiliary Release Contact of camera body, allows a cable release to be used.
When the camera i s mounted on a tripod for copy work, close-ups or telephotography at long (slow) shutter speeds, the small amount of vibration due to mirror-bounce, which is normally o f no consequence, may cause blurring of the image due to the high magnification encountered in extreme close-ups and telephotography. Mirror shock can be eliminated by locking the mirror in the up position before making the exposure.
. To lock the mirror up, move the 1. Mirror Lock-up Lever to M. UP until it clicks. 2. With this setting, the mirror is locked up. Naturally, no image can be seen on the screen through the viewfinder. Consequently, when adjustments for composition and focusing are required return the mirror to its normal position. (lower the mirror). *When using the 70mm Leaf Shutter Lens, be sure to refer to the instructions packed with the lens.
To attach to tripods with a 3/8" screw unscrew the small screw found in the base of the cameras tripod socket. using a regular screwdriver (-). Next, remove the adapter @ by inserting a coin in the slot. Finally, attach the camera to the 3/8" tripod. When attached to the accessory Revolving Tripod Adapter, the Mamiya M645 Super can be instantly rotated to change from vertical to horizontal format, or vice versa.
In order to have the capability of delayed shutter release, you must first insert an optional Cable Release Adapter 2 into the cameras Auxiliary Release Contact, and any commercially available self-timer cable release can be used.

The Roll Film Holder cannot be Removed. (a) Check that the Dark Slide has been inserted.

(c) Place the camera in the outside air only during the moment of exposure.
7. Precautions for AE Shooting (a) Set the film holders Film Speed Dial to the sensitivity of the film to be used.
When the camera is not used for a long period of time, remove the battery and any film from the camera. Avoid storing the camera for prolonged periods of time in a damp or salty atmosphere. (Color film should be stored at the manufacturers recommended temperatures,) Since cameras are precision instruments, avoid shocks and rough handling. When the camera is stored for a long time, periodically remove the camera and release the shutter several times to keep the camera in good condition.
Cleaning: Never touch the lens or mirror surfaces. When your camera is contaminated with dust, fingerprints and so on, blow away the dust particles with a blower, and clean the lens surface with lens cleaning tissue and lens cleaner. Merely blowing dust particles off the mirror surface is sufficientnever touch the mirror. Periodic Check: Periodically check the camera to make sure that it is in working order. This is especially important before a photographic assignment. (Check the battery, flash synchronization, mirror and shutter movement, film wind, diaphragm automation and so on.) If the camera is malfunctioning, take it to the nearest authorized Mamiya Service Center for repairs.

<Self-timer> Self-timer for delayed shutter release. When activated it will light a red pilot lamp in the front of the camera for eight seconds and will blink for two seconds before triggering the shutter. <Time Exposure> Time exposures are made by utilizing the Self-timer and the "B" shutter setting. A new power saving circuit design switches the battery off and extends is life.
TTL (through-the-lens) Flash Exposure Automation
8. A Broad Accessory System For Specialized Applications
A useful accessory system to serve the specialized needs of the photographer. It includes Auto Bellows and Auto Extension Rings for close-up and copying work; Infrared Remote Control for studio and nature photography; External Battery Case for operating in cold surroundings; Camera Grips for convenient holding and more.
The light that hits the film surface during exposure is reflected to a photoreceptor within the camera body which automatically adjusts the flash output to the required level.

Other Features

<Mirror Lock-up> After focusing, the mirror can be locked up before making an exposure. This is convenient when the camera is used at slow shutter speeds and is mounted on a tripod for telephotography, copywork, etc., since even a very small amount of vibration should be eliminated. <Self-timer> Shutter will be released 10 seconds after shutter button is pressed. <Time Exposure> When making time exposures, the battery circuit is automatically disconnected, to save battery power. This is especially useful for astrophotography.

While pushing lens release button @ backwards, turn lens counterclockwise. (Same procedure as removing body cap).

3. Align the right-hand side of this empty spool with the lower Spool Stud 8 (convex). Slide the spool into position making sure that the leftside of the spool is properly held by the Spool Clip.
4. In the same manner, insert a roll of film in the upper compartment. At that time, check that the film leader paper is set as shown in the photo above. (The leader paper inside is facing outward on the pressure plate. Note that the film direction is wrong if the leader paper is facing inward.) 5. Pull out some of the leader paper. Insert the tip of the leader paper into the slot of the lower Take-up Spool.

6. Gently rotate the take-up spool as shown in the photo until the start mark on the leader paper is aligned with the start mark (a) on the spool clip. * Correctly align the start marks with each other, making sure that the film feeds properly. When improper feeding occurs, the proper number of exposures may not be taken. * Avoid exposing the film to direct sunlight when inserting or removing film. @I
* 220 Film Loading Caution 220 films have two types of Start Mark Lines across the paper leader. Always use the second one, a solid line with the legend Start Mark for standard cameras, located about 14cm (5 1/2), behind the first, dotted Mark line.
DO NOT use the dotted line for a start mark.

Shutter Speed Settings

The yellow 2 and 4 are full seconds. B (shutter stays open as long as it is depressed) is also yellow. 4. Red 60 is 1/60 sec. It is colored red to remind you that it is the fastest speed useable with electronic flash. 5. Note: When a Metz Electronic Flash Unit, together with SCA 396 module, is attached to the camera, the camera sets itself automatically to 1/60 sec., irrespective of the dial setting. * When manually selected shutter speeds are set on the shutter speed dial, the intermediate shutter speeds available in the AE operation are not obtainable.
3. Wind up. Wind up the crank handle until it stops. In the film counter window, the number 1 appears, and the film and shutter are set.
How to set the Shutter Speed Dial 1. Set the desired shutter speed against the white index line (A) on the shutter speed dial. 2. At the red A" (for Automatic) and AEL (for Automatic Lock) settings, the shutter speed dial is locked between these two positions. These settings will only function if an AE Finder is mounted on the camera. To release this lock push button (B) while turning dial. 3. All while numbers are fractional seconds. (i.e. 30 =1/30 sec). @

Aperture Ring/Stop-down Operation
* When the AE Finder is used, be sure to return the A/M lever to A (Auto), after having checked the effect of the manually set aperture. The AE finder measures the required exposure through the lens at maximum aperture and will give false results if lever is left in M position.
Set the desired f/stop on the aperture Ring 6) by aligning the f/number with the red reference dot SC@ in the center of the Scale Ring. The Aperture Ring has a click stop for each f/ stop. In-between settings can also be used.
The effect the set f/stop will have upon the picture area can be confirmed on the Finder Screen. Move the AM Lever on the lens so that M becomes visible-the lens then can be stopped down to the preselected aperture.

0 Focusing 4B

While looking through the viewfinder, turn the lens Focusing Ring until the most important subject part appears sharp and clear. Focusing with the Standard Focusing Screen N Type E r-
1. The camera comes equipped with a bright, Type E, Rangefinder/Microprism Focusing Screen. It features a center, split-image rangefinder spot and the subject is in sharp focus when the split images combine into one. 2. The microprism ring around the split-image center further facilitates focusing. The microprisms disappear only when the subject is in sharp focus.
3. The rest of the ground glass area can also be used for focusing. *Interchangeable F o c u s i n g Screens There are five additional focusing screens available for specialized applications. They are easy to interchange and come with instructions.

Depth of Field

Reading the Depth of Field Scale Depth of field is defined as the zone of sharpness before and behind the plane of focus. It depends on camera subject/distance, focal length of lens, aperture setting and distance the lens is focused at.
1 I For example, with the 80mm f/2.8N lens focused at 3m and the aperture set at f/22, the depth of field scale indicates that the zone of sharp focus will extend from about 2m to 6m. In addition to visual observation, the Depth of Field can be determined by using the Depth of Field Scale on each lens. f/stop numbers appear on both the right and left side of the red index mark in the center of the scale ring. Simply read the figures which appear above the f/stop numbers on the distance scale of the lens.

Film Advance and Unloading Exposed Film
Film Advance Unloading Exposed Film * Move the empty spool from the top to the lower (take-up) compartment, ready for loading the next film roll. *Never load, unload or handle film in direct sunlight.
1. Giving the Film Advance Crank one complete turn, will cock the shutter and mirror and ready the camera for the next exposure. 2. When the film is completely exposed (15 exposures on 120, 30 on 220 film), the crank stop will disengage. Continue turning until the paper trailer is completely wound onto the take-up spool. (About five turns after the last exposure.)
3. Open the Back Cover, and remove the Roll Film Insert. The Exposure Counter will return to S (start) automatically. 4. Pull the Spool Clip on the roll film insert out to remove the film. 5. Remove the film from the roll film insert; make sure that the film on the roll does not loosen, and seal immediately.
Using the Self-Timer/Delayed Shutter Release
* After using the self-timer mode, be sure to return the Shutter Release Selector to the White Square. (Normal mode.) -k To override the self-timer, after having pressed the release, move the selector back to the white square. * The Self-Timer can also be overridden by inserting the Dark Slide into the Film Holder or setting the camera Shutter Speed Dial to B. Please note: If you want to use the self-timer with the shutter speed dial set at A or AEL and there is no AE Finder attached to the camera, it will not release the shutter even though the light goes on for 10 seconds. However, when the dial is set to manual speeds, the selftimer will function.
To use the Self-Timer, set the Shutter Release Selector to @ and press the Shutter Release Button.
The Battery Check Lamp will light for 8 seconds and blink for 2 seconds, whereupon the shutter will go off.

Time Exposures

Multiple Exposures
For time exposures set the Shutter Release Selector to c, the self-timer mode, and set the Shutter Speed Dial to "B". Press the shutter release and both mirror and shutter will stay open until the shutter release is pressed again. You may also use a cable release together with the cable release adapter. (The battery circuit will automatically switch off to save power.)
* "B" can be terminated by shifting the Shutter Release Selector from 23 or the Shutter Speed Dial from "B"

Aligning the white dot of the Multiple Exposure Lever with the yellow MULTI square, disengages the multiple exposure prevention mechanism, and the film will not advance after an exposure is made and the Film Advance Crank is turned. However, the shutter will be recocked, thus making multiple exposures possible. In this mode the Exposure Counter will not advance.
Mirror Lock-up Photography
* To override the multiple exposure mode or to return to normal operation, be sure to return the levers White Dot against the white square and then advance the film. (If you forget you will continue to make multiple exposures on the same frame.) *When using the AE Prism Finder, set the Shutter Speed Dial to AEL. Press the shutter release halfway and then lock the mirror up. If set to A and the mirror is locked up, LT (long time) will appear in the finder display and correct exposure cannot be obtained. * When using a Leaf Shutter Lens, be sure to read the instructions accompanying it.
This is an important feature when the tripod mounted camera is used at slow or long exposure times and particularly also with use of long telephoto lenses. It eliminates the possibility of even the slightest mirror bounce which may affect image sharpness. Move the Mirror look-up Lever to the yellow M.UP square, after you have composed and focused your picture. This will raise the mirror and the viewfinder image will be blacked out. After use, return lever to normal (white square) position. @

Infrared Photography

Infrared light rays-being of longer wavelength - focus at a slightly different plane and require the following adjustment: 1. Note the Red Index Mark against which you read your distance scale. The red infrared index mark is slightly to its right. 2. After focusing in the usual manner, read the distance scale and move it to the right to line up with the infrared index mark.

@ Using aTripod @

The 300mm and 500mm APO lenses for Mamiya 645 cameras, being also corrected for infrared light rays, do not need an index mark for infrared. * For proper filter and exposure information be sure to consult the instructions enclosed with infrared film. The Mamiya 645 PRO TL Tripod Socket accepts a standard 1/4 tripod mounting screw. For use with tripods having 3/8 mounting screws, first unscrew the small black philips head retaining screw in the center of the tripod socket. Then remove the 1/4" bushing with a thin coin. To re-install the 1/4 bushing, reverse the process.

Flash Photography

In addition to its standard flash sync system, the Mamiya 645 PRO TL 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 from the film surface at the moment of exposure. The.sensw is connected via coilcords to a dedicated electronic Metz SCA 396 thyristor module, which is attached to the flash shoe of the camera. The module has an IS0 dial on which the speed of the film in use is set. The resulting flash exposure automation determines correct flash exposure and automatically adjusts the output of the flash. It also automatically corrects for exposure compensation ordinarily required when using filters, closeup bellows or extension tubes. However, as all TTL systems, it requires manual compensation for differences in film surface reflection characteristics. Compensation is made by adjusting the film speed selector setting an SCA 396 module. The amount of compensation is determined by experimentation. Important: Read Operating Instructions which are supplied with flash unit before use. Always turn off cameras power switch when attaching or removing flash units.

TTL Flash Photography with Metz Flash Units aperture selected is not within the exposure/distance range of the flash. In this case, select a wider aperture setting. When using flash at maximum distance, which requires the full power of theflash unit, recyling time will be longer. Wait for the readylight to go on before firing the next frame. Exposure Compensation with TTL Flash Automation. Because TTL Flash automation reads the light reflecting off the subject, exposure may require manual adjusment in cases where subject and background are predominantly white or black (e.g. bride in white dress against white background; bridegroom in tuxedo against dark background.) In these instances, the resulting TrL exposure will either be under-exposed or over-exposed. For such situations, adjustment of about 1 to 1 l/2 f/stops, plus or minus, may be requiredthroughexperimentation. Alternatively, a hand held incident flash meter reading will show proper exposure in these cases.
1. Attach a Metz flash unit which features TTL function to the camera. Attach the SCA396 module to the cameras flash shoe. Connect the modules coiled cables to the camera and the flash unit. Set the film speed dial on the SCA396 module to the IS0 rating for the film in use. The range of IS0 is 25 to 1250. 2. Move the flash units power switch to ON and the mode selector to TTL. 3. Turn the cameras shutter release selector switch to ON. When the charge cycle is completed you will see an illuminated green 5 readylight in the middle of the right side of the
finder. When the SCA396 module is connected, the cameras focal plane shutter will automatically set at 1/60 sec, and ignore the settings on the shutter speed dial between 1/60 to 1/1000, including A and AEL. Slower shutter speed settings, however, (1/30 to 4 sec.) are not affected and will allow flash synchronization. 4. Set lens to the desired f/stop and shoot. After the exposure is made, the illuminated green f blinks, confirming proper flash exposure. If the illuminated green f does not blink after exposure, it is possible that

Photography with Non-TTL Flash Units <Caution> When using the Hot-shoe, be sure to put an appropriate Safety Cover over the X-sync terminal so that you wont receive a high voltage electric shock if the terminal is accidentally touched. (A Safety Cover is put on the Xsync terminal when the camera leaves the factory.) 1. When using an electronic flash, plug the synchronization cord into the Sync Teminal and set the Shutter Speed Dial to 1/60 sec. or slower. * The Mamiya 645 PRO has an Xsync terminal. Attach a shoe-mount flash to the hotshoe of the camera or the Left Hand Grip GL401 (optional). * Do not use a flash unit specifically dedicated for another camera. It may damage your 645 PRO. * If you use a flash unit whose / flash duration is slower than sec., set the shutter speed dial to 1/30 sec. or slower.

Special Advice To Professional Photographers Your Mamiya 645 PRO TL 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
