1. Features of the Mamiya RB67 Pro-SD
Practical 6x7cm Since 6x7cm format covers an area 4.5 times the 35mm format. excellent picture quality is assured. In color photography, in particular, it demonstrates superior results. The ratio between the length and width of the 6X7cm format is almost the same as that of large sized printing paper, permitting economical enlargements without cropping. The revolving adapter allows quick changeover from the vertical or horizontal format By simply turning the revolving adapter gOa, either a vertical or horizontal format can be selected without moving the camera. Proper picture composition is easily determined by index finder lines interlocked with the revolving adapter. Bright, parallax-free finder With the lens aperture open, the subject appearing on the large, bright focusing screen assures speedy focusing and composing. The parallax-free single-lens reflex Pro-SD thus is ideal for instantaneous photos where the utmost in quality is required. The Pro-SD roll film holders assure excellent film flatness The Pro-SD roll film holders are designed with the utmost consideration given to film flatness and also feature an interlocked multiple exposure prevention system. The newly designed dark slide slot accepts the dark slide from either the left or right side. The 6x8 cm format now possible The Pro-SD body back is designed to permit 6x8cm photography, thus expanding the photographic scope for studio work and in other fields that use 6x8cm. Close-up photography through the full use of the bellows Since the bellows can be extended up to 46mm photographing even the smallest subjects in frame full is possible. When auto extension tubes are used, the subject can be further enlarged. When a standard lens is employed, life-sized (1:1) reproductions are possible only with the tubes. Excellent heat and cold resistance The Pro-SD is mechanically advanced so that is components can function over a wide temperature range from approximately -20C to -50C. Enlarged lens mount Compared to the convetional RB67 Series, the Pro-SD has a lens mount with a diameter 7mm larger. making it possible to accept a new group of high performance sophisticated lenses, such as the APO, shift, and newly designed wide angle lens 75mm. Since the lenses are systematized, a lens suitable for desired composition can be selected. The new lenses are designed with emphasis on color contribution and feature a built-in bulb (B) unit, and the wide-angle lenses have a floating feature to assure improved close-up performance. All Pro-SD lenses use a lens shutter and an electronic flash synchronize for all shutter speeds. Extensive variety of accessories and interchangeable film holders Pro-SD accessories are interchangeable with those of the RB67 Series and are available in a diverse variety, thus satisfying every possible photographic need A wide variety of film holders are avaialble: 6x7cm format 120/200 roll film holders and 6x4.5cm (semi-format) holders for the Pro-SD, as well as 6x7cm and 6x8cm power drive holders, 70mm holder and sheet film holders. All these assure high quality, sharp images over a large picture area.

It is best to become aquainted with the method of releasing the shutter before actually putting film in the camera. Rotate the release lock ring until 1. dot on theonshutteraligned with the white the mark it is body.
Remove the dark slide or pull out until 2. all the triangular holes becomeitvisible. Push the multiple exposure lever on the 3. exposureholder forwardi.e. until multiple roll film to the position the red mark is visible.

4. Push the cocking lever all the way down. 5. Press the shutter release button.
The first steps can be done in any order. After you are thoroughly familiar with the above steps, return the multiple exposure lever to its normal setting.
9. Loading the Film Holder
1. While pressing the back cover, pull out the upper and lower back cover latches and the back cover will open. Remove the film insert. When loading film, avoid direct sunlight: either load the film in the shade or turn your body away from the sun and load it in the shade of your own body. Use 120 roll film with the 120 roll film holder and 220 roll film with the 220 roll film holder.
2. While pressing the spool release pin (A) on the left side of the film insert, insert a new roll of film on the film spool stud. Load the film so that the leader paper can be pulled out along the arrow of the leader paper guide mark (B). Wind the film with the printed side of the leader paper on the holders pressure plate side. If the printed side does not lace the pressure plate side, reload the film, reversing the film position.
3. Pull out the leader paper and insert the tip into the groove of the take-up spool. * Position the film so that the leader paper winds evenly between the spool flanges-if it is uneven, film and photo malfunctions may occur.
Move the film advance lever gently, until the starting mark (arrow) of the leader paper aligns with the starting mark of the holder. The film advance lever can be moved in several short, definite strokes. l If the leader paper is pulled too far, the film may become fogged, so be careful not to go beyond the arrow.
1. Put the insert into the cassette, aligning the top side of the insert with the white dot (A) of the cassette. l If the film insert is attached in reverse, the back cover cannot be closed.
2. While pressing the back cover gently, push the back cover latches (top and bottom) as far as they will go,
Setting Start Mark with 220 Roll Film. To assure even frame spacing, and
prevent overlapping, be sure to wind the film up to the printed arrow start mark, which appears after the dotted line. ifi> NOTE: 1. The outer cassette of the Pro-SD roll film holder (HA-701) can be used for both 120 and 220 film inserts. 2. The film insert of the Pro-SD roll film holder cannot to be attached to the outer cassette of the Pro-S roll film holder.

DO NOT use the dotted line for a start mark.

Exposure Counter

Film winding for first exposure
When the film is completely advanced, the numeral 1 will appear in the exposure counter and the red film-advance warning will disappear indicating that the holder is ready for photography. l The shutter cannot be released unless the film from S (start) to 1 has been completely advanced with the cocking lever.
1 0. Operating the Revolving Adapter
(Changing the Picture Format to Horizontal or Vertical)
Operating the revolving adapter
When the horizontal format mark of the revolving adapter is facing upward, a horizontal photo will result. For a vertical photograph, turn the revolving adapter clockwise until it stops. To change from vertical to horizontal, turn the revolving adapter counterclockwise. In either case, be sure to turn the adapter a full until it clicks and stops. If the adapter is stopped midway, the shutter release button cannot be pressed. l Do NOT turn the revolving adapter while the shutter release button is being pressed. Especially, when a cable release or a selftimer is used, and adjustment of the release tip is improper, the shutter release button will remain depressed after the shutter is released. Please note!
Horizontal picture format
When the revolving adapter is positioned for horizontal format photos, the solid red lines on the ground glass focusing screen indicate the limits of photo composition. 20

Vertical picture format

When the revolving adapter is positioned for vertical format photos, the broken red lines on the ground glass focusing screen indicate the limits of photo composition.
Setting the Shutter Speed and the Apertur
Removing/attaching the revolving adapter
To remove the revolving adapter, pull down the R-lock lever (A) on the back bottom of the camera. To attach the revolving adapter, position the white dot on the side of the adapter towards the upper side of the camera, and completly push in the R-lock lever while firmly holding the adapter to the camera body. l The revolving adapter for the Pro-S can also be used. l When attaching the revolving adapter, securely hold it to the camera body. A loose attachment may cause incorrect focusing or leakage of light.
Setting the shutter speed Align the desired shutter speed with the red dot on the center of the lens barrel. Always set the shutter speed to the click stop position: intermediate shutter speeds cannot be used. If the speed is changed, after cocking the shutter, do not turn the shutter speed ring rapidly.

15. Unloading the Film

Handling of Exposed Film 0 DO NOT remove exposed film from
the camera unde direct sunlight. Find a shaded area or turn your back to the sun and shade the camera before you open it. When removing the exposed film, be careful to prevent it from unraveling on the spool. Gently tighten the paper trailer, moisten the attached seal, and secure the film to prevent light leaks. Immediately place exposed film in your camera case or a bag, away from sunlight.
After completing the last exposure, completely wind the backing paper on to the take-up spool.
1. Open the back cover of the holder and remove the film insert. Press the right side spool release pin, remove the full spool, then wrap and seal the film to protect it from loosening. 2. Move the empty spool to the take-up side and the camera is ready for reloading. l The exposure counter automatically resets to S (start) as soon as the back cover is opened. l When the exposure counter shows other than S, film is in the holder. Be careful not to open the back cover in this mode!
Winding up film when unexposed frames remained in the holder

16. Distance Scale

17. Depth-of-field
Distance from the film plane to the subject can be determined by the distance scale (A). Each lens features different distance scale curves as pictured above. The figure on the distance graduation (B) which align with the curve indicates the distance to the subject. For example, if the distance graduation and the curve are as shown in the photo after focusing with the 127mm lens, distance to the subject is 1.5m (5ft).

The focusing screen

1. Set the desired aperture by turning the aperture scale ring and then adjust the focus. 2. Depress the depth-of-field preview lever (A) and the depth-of-field can be observed on the ground glass focusing screen. Upon removing your finger, the lever will return to its original position and the lens aperture will fully reopen.
Using the depth-of-field scale
1. Turn the distance scale lever and align the figure representing the focused distance with the center index on the depth of field scale. 2. The two distances (on both sides of the center index) opposite the same figures as the actual lens aperture on the depth-of-field scale are the near and far limits of depth for a given distance and lens aperture. For example, when photographing a subject 5 meters away with the 127mm lens at an aperture of f/32, objects from about 3 to 13m will be in focus.
The curve for each lens is marked with a white dot. Since the dot coincides with the right-hand lens indicator, use it to quickly find the curve on the scale for the lens used.
18. Time (T) exposures, Flash Photography

To make a time exposure, first set the shutter speed ring to T and screw a cable release into the bulb socket. After doing so, the shutter will remain open upon depressing the shuner release button. The shutter will be closed by pressing the plunger of the cable release without giving any shock to the camera. The shutter can also be closed by following procedures.
1. depressing the bulb socket by finger 2. turning the shutter speed ring toward 1 sec. (1) 3. pressing down on the shutter cocking lever about 30
When the shutter is closed by the shutter cocking lever, the lever is locked by the reverse motion stopper and does not return to its original position. When the shutter is cocked by further depressing the lever, the lever returns to its original position.
Do not move the shutter cocking lever until just before closing the shutter. When the shutter is closed by the shutter cocking lever, the light baffle in the camera body drops down slightly; however no fogging occurs,
Changing the Focusing Screen)

Flash photography

Connect the cord of the flash unit to the synchroflash terminal (X contact). The flash unit synchronizes at all shutter speeds.

Attaching and detaching

First remove the waist-level finder, then while holding both sides take out the focusing screen. To attach it, hold each side and insert the focusing screen into the top of the camera body and press down lightly. NOTE: When the focusing screen has been detached, do not touch the picture format red rod indicator on the side of the camera body.

Determining the aperture

The aperture setting for flash photography is determined by dividing the guide number of the flash unit by the subject distance. For example, when photographed with IS0100 in m.
Seven types of interchangeable focusing screens are available to meet various photographic applications. l The focusing screen is made of acrylic resin, and since its surface is soft and susceptible to damage, be carefully so as to not get fingerprints or other foreign matter on it. When dust is wiped off with a cloth or lens paper, static electricity attracts more dust. So, use a blower brush to remove dust.
(Guide number) 40 = (Correct aperture setting) 8 (Subject distance) 5 (m)
20. Mirror Lock-up Photography
The mirror lock-up technique, whereby the mirror is raised beforehand and only the lens shutter is released is ideal for situations where vibrations must be completely eliminated. Specifically close-up photography, using telephoto lenses and in applications where long or slow exposures are necessary mirror lockup is ideal. With a tripod and cable release, the mirror lock-up mode ensures the utmost in sharpness.
Preparations 1. For mirror lock-up operation, securely screw a cable release into the lens socket as pictured. When the socket slightly elevates the camera will be in the mirror lock-up mode. 2. To cock the shutter and the mirror, press the cocking lever forward as far as it will go. Either Step 1 or 2 can be performed first. 3. Upon depressing the shutter release button the mirror will rise, but the shutter will remain closed. 4. Press the plunger of the cable release and the shutter will operate. NOTE: Unless the cable release is removed from the mirror lock-up socket, the camera will remain in the mirror lock-up mode and the film 30

cannot be exposed even when the shutter release button is pressed. When mirror lock-up photography is completed, be sure to remove the cable release. If the red line around the mirror lock-up socket is still visible, when the cable release is removed, the camera is still in the mirror lock-up mode. So,be sure that the cable socket sinks and the red line disappears. As shown in the photo, some lenses use a mirror release operating knob. When using a lens with a knob, pull out the mirror release operating knob (A), turn it clockwise, and screw the cable release into the knob aligning the red dot on the knob with the MIRROR LOCK-UP indicator. When mirror lock-up photography is completed, be sure to remove the cable release and return the knob to its original position.
Using the Mirror Lock-up Cable Release
1. When exposure is shorter than 1 second: (1) Screw the short cable into the mirror lock-up socket, and screw the long cable into the shutter release button. (2) By pressing the cocking lever forward as far as it will go,cock the shutter and the mirror. (3) The first stroke will make the mirror rise, and the second will release the set speed. *For lenses which use the mirror lock-up operating knob, align the knob with the MIRROR LOCK-UP indicator, screw in the short cable, and screw the long cable into the shutter button. The first stroke will make the mirror rise, and the second will release the set speed. 2. When exposure is longer than 1 second, it is convenient to integrate with time(T): (1) Screw the short mirror release cable into the bulb unit of the lens, and screw the long cable into the mirror lock-up socket. (2) Set the shutter speed ring to T. (3) Raise the mirror by pressing the shutter release button on the body. (4) The first stroke of the mirror release will open the shutter and the second stroke of the mirror release will close it.
21 Multiple Exposure Photography

22 Close-up Photography

Exposure compensation for close-up photography
When the bellows of the camera is extended for close-up photography, and distance between the lens and the film plane increases, image brightness on the film plane decreases, thus requiring an increase in exposure. To adjust the exposure, refer to the exposure compensation scale on the camera body. When a finder with built-in exposure meter (i.e. PD Prism Finder or PD Magnifying Hood) is used, exposure compensation is unnecessary, since TTL metering takes place. When making exposure compensation, refer to the exposure compensation scale on the camera body.
When the multiple exposure lever of the roll film holder is moved forward, the multipleexposure prevention coupling pin disengages. In this mode the shutter can be cocked and released without limit. l The multiple exposure lever can be changed over before or after the shutter is cocked, and also before or after the shutter is released for the first multiple exposure photograph. When the multiple exposures are completed, never fail to return the multiple exposure lever to its original position; otherwise, subsequent photos will also be multiple exposures.

Maximum close-up photography table with
1. After focusing the lens, read the exposure compensation factor on the scale. For example, assuming that the focus was adjusted with the 127mm lens, the result will be as shown in photo above. Look for the same pattern in the bottom column where the side panel lines meet the 127mm lens scale. The numerical value of that pattem (+1 in this case) is the exposure compensation value.
2. Change either the shutter speed or the aperture for exposure compensation. When the exposure compensation value is + 1, open the aperture one step, or slow the shutter speed 1 step. For a 0.5 step cornpensation. use the half-stop aperture scale settings. For example, if your exposure meter shows an exposure setting of (1/60 sec. at f/16), it must be adjusted in the case of the + 1 compensation value to (1/30 sec. at f/16) or (1/60 sec. at f/11).
When using the 50mm and 65mm lenses closer than 1 meter (3% ft), it is necessary to use a lens aperture of f/16 or smaller to obtain satifactory lens performance. Graduations on the upper side of the distance scale represents the belows extension values (mm). This scale is used to obtain exposure compensation values for close-up photography with extension tubes.

Lens hood

The lens hood attached to the standard 127mm lens can be used for the 90mm lens. l Screw the attachment ring into the front of the lens mount. l Pull the folded rubber hood straight out. l The lens hood may be left on when the camera is being carried - simply push back and turn out the hood while it is attached to the lens. l A filter can be screwed in between the lens and the hood, or in front of the lens hood.

Using a tripod

The use of a large, sturdy tripod is recommended for optimum picture quality. 1. The standard tripod has a 1/4 inch tripod screw. Simply attach the RB67 Pro-SD as you would any other camera with standard threads. 2. When using a tripod with a 3/8 inch screw, first remove the small screw in the base of the tripod socket by turning if counterclockwise with a coin or an appropriately sized screw driver. Next, remove the 1/4 inch adapter (A) from the tripod socket by rotating it counterclockwise. The camera can then be mounted on a 3/8 inch screw tripod.

23 How to use the Carrying Strap

Attaching the Strap

Hold the metal clamp of the strap so that the key-hole shaped opening faces the Carrying Strap Lug on the camera body. Gently fit the upper part of the key-hole opening over the lug. Next, gently push the bottom of the metal clamp upwards and it will lock in place with a click.

Three Carrying Positions

Depending upon the way the strap is attached to the camera, there are three ways of carrying the camera as shown in the accom panying illustrations Since the Carrying Strap Lug is not rotary, the carrying strap will not become twisted.
If the clamp is attached to Accessory-shoe side of the camera upside-down, it will be difficult to remove, so be careful to attach the clamp rightside-up.

Removing the Strap

Reach behind the strap and while gently squeezing the top of the protruding front plate (leaf spring), slide the clamp downward and off the lug.

Mamiya RB67 Pro-SD Operation Diagram
Attaching a lens with the shutter released or the mirror raised
When a lens is removed from the body, the mirror is set (lowered) and the lens shutter cocked. Conversely, when attaching a lens, the same conditions should prevail (mirror set and shutter cocked). However, should a lens be attached with either the mirror raised or shutter released, or both, the camera can be reset by following the procedures outlined below. 1. If the mirror is raised (regardless of whether the lens shutter is cocked or released), simply depress the Cocking Lever to reset the camera. 2. If the mirror is set and lens shutter released (closed), remove the Dark Slide from the Film Holder and depress the Shutter Release Button (the film will not be exposed). Next, depress the Cocking Lever to reset the camera.

Periodic Check

Periodically check the camera to make sure it is in working order. This is especially important before beginning a photographic session or assignment. Check the battery, flash synchronization, mirror and shutter operation, diaphgram funcitioning and film advance. Also check any accessories you plan to use. For a general overhaul, cleaning, or minor repair, take the camera to your nearest authorized Mamiya Service Center or see your camera shop for advice.
When using the RB67 Pro-SD for special important photos for on location photography, weddings, overseas trips and or other important photography, be sure to take some trial photos and check all functions. It is advisable to put your camera in for periodic check-ups (at intervals of one to two years) to thus ensuring the best photography at optimum performance.

0 Features of Mamiya RB67 Pro-S
The Mamiya RB67 Pro-S is a unique, high-grade, 6 x 7cm lens-shutter type, single-lens reflex camera developed to offer excellent picture quality and easy handling. Mamiya feels confident that the extensive versatility and capabilities of the Pro-S will meet and satisfy the requirements of all photographers.

1. Rational 6 x 7cm format
Since the 6 x 7cm format covers an area 4.5 times the m m format, excellent picture quality is obtainable. Especially, it demonstrates superb results in color photography. The ratio between the length and width of 6 x 7cm formats is almost the same as that of large photographic paper, permitting economical enlargements without cropping. When designing a magazine layout, a sufficient blank space is reserved for headlines and explanatory notes, s o that the entire picture format can be fully utilized.
2. Single-lens reflex camera offering a bright, large finder image
Since parallax-free focusing in the outstanding feature of the single-lens reflex camera, speedy camera operation is possible through brilliant, precise 6 x 7cm picture composition.
3. Excellent Mamiya Sekor lenses
Mamiya Sekor lenses boast excellent image rendition and color balance. Various types ranging from wide-angle lenses to telephoto lenses are available.
These lenses are rationally grouped in series, whereby those exactly adaptable to ones particular photographing objectives are optionally selectable with ease.
6. Vertical or horizontal picture format quickly changed over with the revolving adapter
A revolving adapter is provided as a standard outfit, whereby the vertical or horizontal picture format is promptly selected by turning the camera body back by 90. without changing the camera position. This is especially convenient when the camera is mounted on a tripod.
4. Lens-shutter system suitable for electronic flash photography
By adopting the lens-shutter system, electronic flash is synchronized with all shutter speeds, making it possible to produce highly impressive photographs.
7. Finder format index interlocked with revolving adapter
When the revolving adapter is turned up to 90, horizontal format picture index red lines appear (or disappear), presenting proper picture composition.
5. Double-exposure prevention and multiexposure devices
An interlocking device for double-exposure prevention is incorporated in the Pro-S roll film holder. Since this device is interlocked with the Pro-S body mechanism, the shutter cannot be released unless the film is advanced. Also, film advance for the next exposure is impossible unless the shutter is released. When the shutter is released, the film wind-stop is automatically released. Multiple exposure photography is available simply by switching a lever.
8. Excellent film flatness ensured by Pro-S roll film holder

Various tests have been applied to the Pro-S roll film holder to stabilize film flatness. As a result, film flatness has been further improved.
9. Camera back adapter changeable according to photographing objectives
By changing the back adapter, depending on your photographic objective, the range of film applications can be widened to include 120 and 220 roll films, dry plates, cut films,
and 70mm film. The film holders and back adapters are very easily exchanged.
on the photographing objectives, a checker, a rangefinder spot, a microprism, and a cross-hair can be selected at your option.
10. Unique mirror shockless mechanism
By adopting a unique centrifuged friction governor system, the mirror functions smoothly without sensing shocks. Mirror shock, constituting the most important problem involved in large, singlelens reflex cameras, has been solved.
12. Excellent heat- and cold-resistant capacity
Camera component parts are capable of demonstrating their functions within a wide temperature range from approximately 120F to - 5OF (5OOC to - 2OOC). The lens-shutter maintains accurate function, even in severe cold, and shutter speed deviation is negligible. Its resistivity to coldness is superb. Although the camera operating unit grows sluggish at or below 15OF (-loo C), it is sufficiently capable of operating the camera until the temperature drops to approximately - 50 F (-ZOO C).
11. Large variety of finders
A big selection of finders conforming to your photographic objective are available. They include a CdS finder (appropriate exposure obtainable with Through-the-lens measuring system), a Prism finder (subjects can be seen as an erect image), a CdS prism finder (former two types of finders are combined). a Magnifying hood (easily visible and bright), a Dual magnifying hood (performs precision focusing by speedily changing the magnifier of high magnification), and a Universal sportsfinder (permits focusing on the focusing screen after it has been installed). The focusing screens are also easily exchangeable. Depending
13. Mirror-up photography (independent mirror release) possible
When sharp pictures are demanded, the mirror-up mechanism plays a big role. When taking a picture unhurriedly with the camera mounted on a tripod. or when photographing at slow shutter speeds or using a telephoto lens, the mirror-up operation merit is highly effective.
14. Close-up photography through full use of bellows characteristic features

Since the bellows can be extended up to 46mm, photographing small subjects in the frame full size is possible. When auto extension tubes are used, the subject can be further enlarged. When a standard lens is employed, life-size (1 : 1) or larger pictures can be photographed.
17. Dark slide lock for safety while carrying
A dark slide lock is provided for the Pro-S roll film holder so that the dark slide will not slip off while carrying the holder detached from the camera body.

0 Setting the aperture

Align the desired aperture value with the red dot on the center of the lens barrel. * Adopted for the aperture is a fully automatic diaphragm which stops down during shutter operation. * The aperture can be set at full and half click stops.
l Time Operation 1. By setting the shutter speed scale on T (time) and releasing the shutter, the shutter will remain open for an extended time exposure. 2. To close the shutter, turn the shutter speed ring toward the 1 sec. mark or press down the shutter cocking lever about 30? * Do not move the shutter cocking lever until just before closing the shutter. * When the shutter is closed by the shutter cocking lever, the light baffle in the camera body drops slightly lower; however, since it is an extended time exposure, fogging over the actual exposure does not occur. * When the shutter is closed by the shutter cocking lever, the lever is locked by the reverse motion stopper and does not return to its original position. When the shutter is cocked by further depressing the lever, the lever returns to its original position.
Align the desired shutter speed with the red dot on the center of the lens barrel. * Always set the shutter speed to the click stop position. In-between shutter speeds cannot be used. c If the shutter speed is changed, after cocking the shutter, do not turn the shutter speed ring rapidly.

Focusing and Focusing Knob Fixing

0 Distance Scale

Focusing

Focusing knob fixing

When the shutter is cocked, the mirror is cocked simultaneously, and an image is visible on the ground glass of the focusing screen. By turning either the left or right focusing knob, adjust the focus and compose the picture.
After adjusting the focus, turn the focusing knob fixing lever (18) forward and appropriately clamp it, whereby the focusing mechanism is secured. * Deviation in focusing can be prevented in this manner, when continuously taking pictures, taking snapshots with wide-angle lenses, close-up photographs, and using telephoto lenses.
Distance from the film plane to the subject can be determined by the distance scale (5). Curves on the distance scale are represented in a different color for each lens. The figure on the distance graduation (4) which meets the curve for the lens used after focusing reveals the distance to the subject. For example, if the distance graduation and the curve are as shown in the photo after focusing with the 127mm lens, you can confirm that distance to the subject is 5ft. (1.5m) by reading the graduation aligned with the orange curve.

0 Depth-of-field

0 Using a Tripod
Viewing on the focusing screen
Using the depth-of-field scale
1. Set the desired aperture by turning the aperture scale ring (51); then adjust the focus. 2. Depress the depth-of-field preview lever (47) and the depth-of-field can be observed on the ground glass focusing screen. When removing your finger, the lever will return to its original position and the lens aperture will fully reopen. 1. Turn the distance scale lever (48) and align the figure representing the focused distance with the center index mark on the depth of field scale (53). 2. The two distances (on both sides of the center index mark) opposite the same figures as the actual lens aperture on the depth-of-field scale are the near and far limits of depth for a given distance and lens aperture. For example, when photographing a subject 10 feet away with the 127mm lens at an aperture of f/16, objects from about 8 to 13 feet will be in focus. For maximum picture sharpness the use of a sturdy tripod is recommended. Insert the tripod screw into the tripod socket (32) at the bottom of the camera. When a tripod with a 3/8 inch tripod screw is used, remove the inner socket by turning the tripod socket counterclockwise with a coin or similar disk inserted in the slots of the socket. The standard tripod has a 1/4 inch tripod screw and can be used for this camera in conjunction with the inner tripod socket. l

Tripod Mounting Base

The tripod mounting base (33) at the bottom of the camera is for attaching a quick shoe. If you keep a quick shoe on your tripod head, the camera can be quickly and easily mounted on it.

c Close-up Photography

The lens-to.-subject distance represents the distance of the su edge of the lens barrel.

from the front

When the lens is extended for close-up photography, and distance between the lens and the film plane increases beyond normal, image brightness on the film plane decreases, requiring an increase in exposure. To adjust the exposure, refer to the exposure compensation scale on the camera body. 1. After adjusting focus on the subject, read the exposure compensation value obtained on the exposure compensation scale. For example, assume that focus was adjusted with the 127mm lens and the result was as shown in the photo. Seek the same pattern in the bottom column as the pattern where side panel lines meet the 127mm lens scale. The numerical value of that pattern (+ 1 in this case) is the exposure compensation value.
2. Compensate the exposure by changing either the shutter speed or the aperture. When the exposure compensation value is + 1, open the aperture one stop, or slow the shutter speed 1 step. For 0.5 step compensation, use the half-stop aperture scale settings. For example, if your exposure meter shows an exposure setting of (1/60 sec. at f/16), it must be adjusted in the case of the + 1 compensation value to (1/30 sec. at f/16) or (1/60 sec. of f/11). * When using the CdS finder for the Mamiya RB, exposure need not be compensated, since the meter reads actual exposure directly.
* When using the 50mm and 65mm lenses closer than 3 1/4 ft (1 meter), it is necessary to use a lens aperture of f/16 or smaller to obtain satisfactory lens performance. * Graduations on the upper side of the distance scale represents the bellows extension values (mm). This scale is used to obtain exposure compensation values for close-up photography with extension tubes. (Refer to the next page.)
0 Close-up Photography with the Auto Extension Tubes
7. Since it will decrease resolving power due to exceeding life-size, do not use the auto extension tube with the 50mm lens. Close-up photography table 1. Distance indicates the distance from the front edge of the lens barrel to the subject. 2. The figures in the left column of the close-up table indicate no bellows extension. The figures on the right indicate when the bellows is extended to the maximum (46mm).
l How to determine the exposure compensation value 1. After focusing the lens, read the extension amount through the bellows extension scale (A) on the top of the distance scale. 2. Find the compensation value by the Bellows extension scale/Exposure compensation value located on the right side of the close-up photography table. For example, assume that 127mm lens is focused after combining it with No. 2 auto extension tube. If the extension amount reads 35mm by the bellows extension amount scale, it is understood that the compensation value is + 2 steps by the scale located on the right side of the close-up photography table. In this case, increase exposure by setting the shutter speed dial two steps slower or by opening the aperture by two steps. f W h e n u s i n g t h e CdS f i n d e r f o r t h e Mamiya RB. exposure need not be compensated, since the meter reads actual exposure directly.

0 Mirror-up Photography (Independent Mirror Release)
l Photographing 1. On pressing the shutter release b u t t o n, the mirror and the light baffle will snap up, but the shutter will not be released. 2. R e l e a s e t h e s h u t t e r w i t h t h e c a b l e release. (When you do not have a cable release, simply return the mirror release Operating knob to the original position to release the shutter.) 3. By pulling out the knob and turning it counterclockwise, the mirror-up mechanism can be disengaged. * Even when picture-taking is switched to mirror-up photography, the mirror is set at each shutter cocking. Accordingly, it is possible to confirm the image on the finder screen prior to taking each picture. d For this type of photography, an ideal forked mirror-up cable release is available as an optional accessory. NOTE: Unless the mirror release operating knob is returned, the camera will remain set for mirror-up photography. In this case, the film will not be exposed even when the shutter release button is pressed.
In mirror-up photography, previously release the mirror and operate only the lens shutter at the moment of taking the photograph. This mirror-up photography is recommended When a tripod is employed and the shutter is released at slow speed, when taking close-up photos, or when using a telephoto lens, where avoidance of even a negligible shock is desired, or when curtailment of even a negligible time lag between pressing the shutter release button and the shutter opening is desired
l Preparations 1. Pull out the independent mirror release operating knob (50) and turn it clockwise, and align the red dot on the knob with the MIRROR UP indication dot. 2. Screw a cable release into the female
screw socket in the knob center. 3. By fully pressing down the shutter cock. ing lever, cock the shutter and the mirror. The sequence of foregoing procedures 1, 2, and 3 can be optionally altered.

I When attaching the revolving adapter, press it firmly so that it is attached tightly and never comes loose. If the adapter is attached somewhat loosely, it will cause light leakage. x: The revolving adapter of the Pro-S is not applicable to the former RB67. * Since the revolving adapter for the former RB67 has no interlocking mechanisms (such as a double-exposure preventive device, a horizontal picture format marking device, and a safety device f o r p r e v e n t i n g t h e shutter from releasing when the dark slide is i n s e r t e d ). d o n o t e m p l o y it w i t h t h e Pro-S bbdy.
When desiring to pull out the dark slide of the roll film holder which has been removed from the body
Releasing the lens shutter which has been removed from the body
Shutter testing when the film is loaded
When the roll film holder for the Pro-S is removed from the body, the safety device prevents its dark slide from being pulled out carelessly or accidentally. However, if you desire to pull it out, it can be pulled out by using your fingernail tip to press the dark slide lock release lever (40) on the bottom of the outer cassette.
It is advisable to release the shutter when the lens is not to be used for a long period. To release a lens shutter which is removed from the camera body, turn the cocking pins (56) clockwise, while pressing the shutter lock pin (55) with a finger. The cocking pins should be turned all the way; do NOT leave the pins turned only halfway.

This operation can be utilized for shutter testing prior to photographing. * When pulling out the dark slide. stop pulling at a point where the entire triangular hole on the dark slide becomes visible. If the shutter is released when the dark slide is pulled out beyond that hole, the film will be exposed to light. * When the shutter is released, a red mark appears on the exposure counter. * When taking the first photograph subsequent to this test, cock the shutter in the multiexposure condition, and pull out the dark slide. For taking pictures following the first one, restore the multiexposure lever to its normal position and continue photographing.
