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.

12. Focusing and Focusing Knob Fixing

Focusing

When the shutter is cocked, the mirror is cocked simultaneously, and an image is visible on the ground glass focusing screen. By turning either the left or right focusing knob, adjust the focus and compose the picture.

Focusing knob fixing

After adjusting the focus, turn the focusing knob fixing lever forward and clamp it to secure the focusing mechanism. l Once secured deviations in focusing are prevented-ideal for conditions of continuous photo taking.

13. Taking Photographs

Advancing the film and cocking the shutter
@ Film advancing @ Shutter cocking @ Shutter releasing However, either advancing the film or cocking the shutter can be conducted first.

Advancing the film

1. Take out the dark slide and release the shutter. When the shutter is released, the red mark will appear in the exposure counter indicating that the film has been exposed. 2. As the shutter is released, simultaneously the film wind-stop mechanism is automatically disengaged, and the film can be advanced to the next frame. When film is advanced one full frame, the figure in the exposure counter advances and the red mark will disappear.
The multiple-exposure coupler will prevent shutter release unless the exposed film frame is advanced. A multiple-exposure photographic mode is an added feature. Wind the film advance lever in a slow, steady manner to avoid film advance problems. Although the film advance lever cannot be reversed until it is wound up to the initial 70, it can be moved in several short, definite strokes thereafter.

Storing the dark slide

When photographing, the dark slide may be conveniently kept in the storage on the back of the holder. It can be inserted either from the right or left side.
The dark slide can also be stored on the side of the camera body as pictured.

Memo clip

The clip on the back cover can be used for holding the cover of a film box or a slip of paper to record photographic data.
14. Testing the Shutter When the Film is Loaded
When the shutter is cocked with the darkslide partially pulled out (approx. 5mm) and the shutter release button is pressed, the shutter can be released without exposing the film in the roll film holder to light. This operation can be utilized for testing the shutter prior to photographing. When pulling out the dark slide, stop when 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 will appear on the exposure counter. When taking the first photograph subsequent to this test, cock the shutter in the multiple exposure mode (see page 32), and pull out the dark slide. After the first photo is taken, move the multiple exposure lever back to its normal position and continue photographing.

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.

By winding the film advance lever until it stops, the figure 1 will appear in the exposure counter (39), the red mark indicating incomplete film winding will disappear, and the film will be positioned for the first exposure * Unless film winding from S to 1 in the exposure counter is completed, the shutter cannot be released.

Film advancing

* Wind the film advance lever in a slow, steady manner to avoid film winding problems. * Although the film advance lever cannot be reversed until it is wound up to the initial 70 winding, it can be moved in several short, definite strokes thereafter. c The film wind-stop release lever provided for the Pro-S roll film holder is to be used when the holder is used for the Mamiya Universal Press, or when desiring to wind up to the film end while unexposed film remains in the holder. 3. When you finish exposing the full number of e x p o s u r e s , t h e s h u t t e r r e l e a s e b u t t o n cannot be depressed and the film advance lever will be freed. Then wind the film completely to the end of the leader paper. l
Film advancing and shutter cocking
Exposed Film advance completed (Before exposure)
1. Draw out the dark slide and release the shutter. When the shutter is released, the red mark appears in the exposure counter, indicating that the film is exposed. 2. Simultaneously when the shutter is released, the film wind-stop mechanism is automatically disengaged, and the film can be advanced for the next frame. When film is advanced one full frame, the figure in the exposure counter is advanced, and the red mark disappears. * Unless the exposed film frame is advanced, shutter releasing is prevented by the coupling device for double-exposure prevention. + Shifting to multiple exposure photography is possible. Refer to the next page. * Even though film advance is completed, the shutter cannot be released if return of the film advance lever is hindered by your fingers or by another object.

Unloading the film

1. Open the back cover of the holder and remove the film insert. Press the right side spool release pin (43), 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.

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.

3. When photographing through the extension tubes, use as small an aperture as possible. 4. When photographing in the 6 x 7 size, if the 127mm lens is used, minimal or no corner vignetting will occur, however, when using lenses other than the 127mm lens with two extension tubes (No. 1 and No. 2), the possibility of some vignetting in the four corners of the picture may occur. When using only one extension tube, no vignetting will occur with any lens. 5. When photographing with the Polaroid Land film pack, corner vignetting increases due to the larger picture size, however a 6 x 7cm portion in the center of the photo will be essentially clear of vignetting. 6. Use only one auto extension tube No. 1 for the 65mm lens.
