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 easyhandling. Mamiya feels confident that the extensiveversatility and capabilities of the Pro-S will meet andsatisfy the requirements of all photographers.

1. Rational 6 x 7cm formatSince the 6 x 7cm format covers an area 4.5 times the 3 5 m m

format, excellent picture quality is obtainable. Especially, it demon-

strates 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, so that the entire

picture format can be fully utilized.

2. Single-lens reflex camera offering a bright, large finderimage

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 lensesMamiya Sekor lenses boast excellent image rendition and color

balance. Various types ranging from wide-angle lenses to telepho-

to lenses are available.

2

These lenses are rationally grouped in series, whereby those

exactly adaptable to one’s particular photographing objectives are

optionally selectable with ease.

4. Lens-shutter system suitable for electronic flashphotography

By adopting the lens-shutter system, electronic flash is synchro-

nized with all shutter speeds, making it possible to produce highly

impressive photographs.

5. Double-exposure prevention and multiexposuredevices

An interlocking device for double-exposure prevention is incor-

porated 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 expo-

sure 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.

6. Vertical or horizontal picture format quickly changedover 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.

7. Finder format index interlocked with revolving adapterWhen the revolving adapter is turned up to 90”, horizontal format

picture index red lines appear (or disappear), presenting proper

picture composition.

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 photo-graphing 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,

3

and 70mm film.

The film holders and back adapters are very easily exchanged.

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, single-

lens reflex cameras, has been solved.

11. Large variety of findersA big selection of finders conforming to your photographic ob-

jective 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

on the photographing objectives, a checker, a rangefinder spot, a

microprism, and a cross-hair can be selected at your option.

12. Excellent heat- and cold-resistant capacityCamera component parts are capable of demonstrating their

functions within a wide temperature range from approximately 120°F

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).

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.

4

14. Close-up photography through full use of bellowscharacteristic features

Since the bellows can be extended up to 46mm, photographing

small subjects in the frame full size is possible. When auto exten-

sion 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.

15. Single-action focusing hoodAvailable as a standard outfit is a collapsible focusing hood,

which can be opened and closed by single action, and which can

be shielded from extraneous light by raising the magnifier. Depend-

ing on diopter of your eyes, the magnifiers are interchangeable. A

double-lock mechanism prevents the focusing hood from acciden-

tally slipping off.

16. Focusing knob fixing device

A focusing knob fixing device is provided so that the focusing

knob will not be moved inadvertently during close-up photography,

taking snapshots, fixed focus photography, or using a telephoto

lens.

17. Dark slide lock for safety while carryingA 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.

16. Accessory shoeAn accessory shoe is provided for convenient use when mounting

the clip-on-type flash unit.

19. Unique safety devicesVarious safety devices eliminate possible photographic failures.

20. Complete set of accessoriesAvailability of a complete set of various accessories further aug-

ments photographic possibilities and camera versatility.

q Changing the Picture Format to Horizontal or Vertical

l Operating the revolving adapter

When the horizontal format mark of therevolving adapter is facing upward, a hori-zontal format will result. To compose avert ical photograph. turn the revolv ingadapter clockwise until it stops. To changefrom vertical to horizontal, turn the revolvingadapter counterclockwise.In either case, be sure to turn the adaptera full 90° until it clicks and stops. If theadapter is stopped midway, the shutterrelease button cannot be pressed.

* Do NOT turn the revolving adapter whilethe shutter release button is being pressed.Especially, when a cable release or a self-timer is used, and adjustment of the releasetip is improper, the shutter release buttonwill remain depressed after the shutter isreleased. Always pay attention to this fact.

l Viewfield of horizontal or vertical format

Horizontal picture formatWhen the revolving adapter is positioned atthe horizontal format, red lines appear onthe ground glass focusing screen to indicatea horizontal picture format. Compose thepicture within the red lines.

15

Vertical picture formatWhen the revolving adapter is positioned inthe vertical format, the red lines disappear.Compose the picture within the broken lineson both sides.

0 Attaching and Detaching the Roll Film Holder

l Removing the rear body cap l Attaching the roll film holder

By moving the slide locks (29) on both sidesfully to the left, the cap can be removed.

* Never push the light baffle (26) on thecamera back after removing the rear bodycap. If the light baffle is pushed by force,it will cause light leakage or a malfunction.

1. Before attaching the holder, confirm thatthe upper and lower side slide locks (29)are on the left end of the indented portionwhen viewed from behind the camera body.

NOTE:Should either slide lock be moved to theright while nothing is attached to the revolv-ing adapter, the slide lock release lever (31)will engage and the slide lock will not move.II this happens, press the release lever (31)and return the slide lock to the open posi-

tion.

2. Attach the roll film holder and slide bothslide locks firmly in the direction of the arrowmark.

(; If the slide lock of the revolving adapteris not pushed fully in or out, the shutter willnot be released because of the shutterlocking safety device. Always operate theslide lock securely.

* If closing the lower slide lock is neglect-ed, the safety device of the Pro-S holderwill prevent the dark slide from being re-

moved.* If the dark slide is completely inserted,or if the film is not loaded, the shutter re-lease button cannot be pressed, leading topicture-taking failure.

16

l Detaching the roll film holder

1. Insert a dark slide in the roll film holder.Two white lines on the side of the holderindicate the position of the inserting slit.2. Remove the roll film holder by slidingboth slide locks (29) in the opposite direc-tion to the arrow mark on the slide lock.

* If the dark slide is not inserted, the slidelock will be locked by the safety device,and the roll film holder cannot be detached.* When a dark slide is completely inserted,the slide lock release lever (31) is automa-tically disengaged, and the slide locks canbe slid without pressing the release levers.

NOTE:Since a coupling device fordouble-exposure prevention isadapted for the Pro-S roll filmholder, the shutter cannot bereleased if the film is not loaded.

When desiring to release the shutterwithout loading the film.

In this instance, the shutter can be released bysliding the multiexposure lever of the roll filmholder to the front, and by setting the shuttercocking lever and pulling out the dark slide.+ When the dark slide is completely inserted,

the shutter release button cannot be pressed.Therefore, either remove the dark slide or drawit outward to a position where the entire trian-gular hole in the top center of the dark slidebecomes visible.* Either operation of the multiexposure leveror the shutter cocking can be initially conducted.

0 Loading and Advancing the Roll Film

l Loading the film

L

1. Open the back cover by pulling out theback cover latch, while slightly pressing theback cover. Remove the film insert fromthe holder.

x; When loading and unloading film, avoiddirect sunlight. Choose a location in theshade.+ Regardless of whether the roll film holderis attached to or detached from the camerabody, loading and unloading the roll filmcan be conducted in the same mannerh Use 120 roll film with the 120 roll filmholder, and 220 roll film with the 220 rollfilm holder.

2. While pressing the left side spool releasepin (43), insert a new roll of film on the filmspool stud.Load the film so that the leader paper canbe pulled out along the arrow of the leaderpaper guide mark (36) In this way, the blackside of the leader paper will appear on theoutside.

+ If the black side does not appear on theoutside, reload the film, reversing the filmposition.

3. Pull out the leader paper and insert thetip into the groove of the take-up spool.

h Position the film so that the leader paperwinds evenly between the spool flanges;otherwise the film may be taken up unevenly,causing trouble.

18

l Aligning the starting mark

Move the film advance lever gently, untilthe starting mark (arrow) of the leader paperaligns with the starting mark of the holder.The film advance lever can be moved inseveral short, definite strokes.

* If the leader paper is pulled too far, thefilm may become fogged. Be careful not togo beyond the starting mark (arrow).

l Attaching the film insert l Film winding for first exposure

1. Put the insert into the cassette, aligningthe top side of the insert with the white dot(A) of the cassette.* If the film insert is attached in reverse,the back cover cannot be closed.2. Close the back cover and fully push inthe back cover latch while pressing theback cover.

NOTES1. The outer cassette of the Pro-S roll filmholder can be used for both 120 and 220film inserts.2. The film insert of the Pro-S roll film holdercannot be attached to the outer cassetteof the former RB67 roll film holder.

By winding the film advance lever until itstops, the figure “1” will appear in the expo-sure counter (39), the red mark indicatingincomplete film winding will disappear, andthe film will be positioned for the first expo-sure

* Unless film winding from S to 1 in theexposure counter is completed, the shuttercannot be released.

* Wind the film advance lever in a slow,steady manner to avoid film winding prob-lems.

Exposed Film advancecompleted

(Before exposure)

1. Draw out the dark slide and release theshutter. When the shutter is released, thered mark appears in the exposure counter,indicating that the film is exposed.2. Simultaneously when the shutter is re-leased, the film wind-stop mechanism isautomatically disengaged, and the film canbe advanced for the next frame. When filmis advanced one full frame, the figure in theexposure counter is advanced, and the redmark disappears.

* Although the film advance lever cannotbe reversed until it is wound up to the ini-tial 70” winding, it can be moved in severalshort, definite strokes thereafter.c The film wind-stop release lever provided

for the Pro-S roll film holder is to be usedwhen the holder is used for the MamiyaUniversal Press, or when desiring to windup to the film end while unexposed filmremains in the holder.

3. When you finish exposing the full numberof e x p o s u r e s , the shut ter re lease but toncannot be depressed and the film advancelever will be freed. Then wind the film com-pletely to the end of the leader paper.

* Unless the exposed film frame is ad-vanced, shutter releasing is prevented bythe coupling device for double-exposureprevention.+ Shifting to multiple exposure photographyis possible. Refer to the next page.* Even though film advance is completed,

the shutter cannot be released if return ofthe film advance lever is hindered by yourfingers or by another object.

l Unloading the film1. Open the back cover of the holder andremove the film insert. Press the right sidespool release pin (43), remove the full spool,then wrap and seal the film to protect itfrom loosening.2. Move the empty spool to the take-upside. The insert is ready for reloading.* The exposure counter automatically re-sets to S (start) as soon as the back coveris opened.c When the exposure counter shows otherthan S, a film is loaded in the holder.

Either film advancing or shutter cocking caninitially conducted. However, the recom-mended sequence of these steps to becustomarily observed is: (1) film advancing,(2) shutter cocking, and finally (3) shutterreleasing.

20

0 Multiple Exposure Photography0 When desiring to wind up to the end of film while unexposed filmremains in the holder.

When the multiexposure lever of the rollfilm holder is moved forward, the couplingpin for double-exposure prevention is dis-engaged, and whenever the shutter cockinglever is set, shutter releasing can be re-peated without limit.

* The multiexposure lever can be changedover before or after shutter cocking, andalso before or after shutter releasing for thefirst multiple exposure photograph.* When taking multiple exposure picturesis finished, never fail to return the multiex-posure lever to its original position; other-wise, failure in taking subsequent multipleexposure pictures will occur.

l Storing the dark slide

When the film advance lever is continuouslywound, with the film wind-stop release lever(42) pushed to the left, the film can be reeledup completely to its end, even though pic-ture taking is still in progress and a filmremains unexposed.

While progressing with photography, thedark slide of the roll film holder can bestored by inserting it into the camera bodyside.

Cl Setting the Shutter Speed and the Aperture

l Setting the Shutter speed

Align the desired shutter speed with the reddot on the center of the lens barrel.

* Always set the shutter speed to the clickstop position. In-between shutter speedscannot be used.c If the shutter speed is changed, aftercocking the shutter, do not turn the shutterspeed ring rapidly.

0 Setting the apertureAlign the desired aperture value with thered dot on the center of the lens barrel.

* Adopted for the aperture is a fully auto-matic diaphragm which stops down duringshutter operation.* The aperture can be set at full and halfclick stops.

l Time Operation1. By setting the shutter speed scale on T(time) and releasing the shutter, the shutterwill remain open for an extended timee x p o s u r e .2. To close the shutter, turn the shutterspeed ring toward the 1 sec. mark or pressdown the shutter cocking lever about 30?

* Do not move the shutter cocking leveruntil just before closing the shutter.* When the shutter is closed by the shuttercocking lever, the light baffle in the camerabody drops slightly lower; however, since itis an extended time exposure, fogging overthe actual exposure does not occur.* When the shutter is closed by the shuttercocking lever, the lever is locked by thereverse motion stopper and does not returnto its original position. When the shutter iscocked by further depressing the lever, thelever returns to its original position.

q Focusing and Focusing Knob Fixing 0 Distance Scale

l Focusing

When the shutter is cocked, the mirror iscocked simultaneously, and an image isvisible on the ground glass of the focusingscreen. By turning either the left or rightfocusing knob, adjust the focus and com-pose the picture.

l Focusing knob fixing

After adjusting the focus, turn the focusingknob fixing lever (18) forward and appropri-ately clamp it, whereby the focusing mech-anism is secured.

* Deviation in focusing can be preventedin this manner, when continuously takingpictures, taking snapshots with wide-anglelenses, close-up photographs, and usingtelephoto lenses.

Distance from the film plane to the subjectcan be determined by the distance scale

(5).Curves on the distance scale are repre-sented in a different color for each lens.The figure on the distance graduation (4)which meets the curve for the lens usedafter focusing reveals the distance to thesubject.For example, if the distance graduation andthe curve are as shown in the photo afterfocusing with the 127mm lens, you can con-firm that distance to the subject is 5ft. (1.5m)by reading the graduation aligned with theorange curve.

c Close-up Photography

l Exposure compensation for close-up photography l Maximum close-up photography table(with bellows fully extended)

When the lens is extended for close-up pho-tography, and distance between the lens andthe film plane increases beyond normal,image brightness on the film plane de-creases, requiring an increase in exposure.To adjust the exposure, refer to the exposurecompensation scale on the camera body.1. After adjusting focus on the subject, readthe exposure compensation value obtainedon the exposure compensation scale.For example, assume that focus was ad-justed with the 127mm lens and the resultwas as shown in the photo.Seek the same pattern in the bottom columnas the pattern where side panel lines meetthe 127mm lens scale. The numerical valueof that pattern (+ 1 in this case) is the expo-sure compensation value.

The lens-to.-subject distance represents the distance of the suedge of the lens barrel.

0 Close-up Photography with the Auto Extension Tubes

l Attaching and detaching the auto exten-sion tubesAttaching and detaching the auto extensiontubes is accomplished in the same manneras with the lens. When initially mounting alens to the extension tube, cock both thelens and the tube.* The auto extension tubes couple withthe automatic diaphragm of the lenses.NOTES1. For exposure compensation, refer to thefollowing table. Reading of the exposurecompensation scale differs from that whennot utilizing extension tubes.

2. For close-up photography, we recom-mend independent mirror-releasing prior toeach actual photograph. This omits or mini-mizes any residual camera body movementdue to mirror action.

3. When photographing through the exten-sion tubes, use as small an aperture aspossible.4. When photographing in the 6 x 7 size,if the 127mm lens is used, minimal or nocorner vignetting will occur, however, whenusing lenses other than the 127mm lens withtwo extension tubes (No. 1 and No. 2), thepossibility of some vignetting in the fourcorners of the picture may occur. Whenusing only one extension tube, no vignettingwill occur with any lens.5. When photographing with the PolaroidLand film pack, corner vignetting increasesdue to the larger picture size, however a6 x 7cm portion in the center of the photowill be essentially clear of vignetting.6. Use only one auto extension tube No. 1for the 65mm lens.

7. Since it will decrease resolving powerdue to exceeding life-size, do not use theauto extension tube with the 50mm lens.

Close-up photography table1. Distance indicates the distance from thefront edge of the lens barrel to the subject.2. The figures in the left column of theclose-up table indicate no bellows exten-sion. The figures on the right indicate whenthe bellows is extended to the maximum(46mm).

l How to determine the exposure compen-sation value1. After focusing the lens, read the exten-sion amount through the bellows extensionscale (A) on the top of the distance scale.2. Find the compensation value by the“Bellows extension scale/Exposure com-pensation value” located on the right sideof the close-up photography table. Forexample, assume that 127mm lens is focus-ed after combining it with No. 2 auto exten-sion tube. If the extension amount reads35mm by the bellows extension amountscale, it is understood that the compensa-tion value is + 2 steps by the scale locatedon the right side of the close-up photo-graphy table. In this case, increase expo-sure by setting the shutter speed dial twosteps slower or by opening the aperture bytwo steps.f When us ing the CdS f inder for theMamiya RB. exposure need not be com-pensated, since the meter reads actualexposure directly.

When desiring to pull out the darkslide of the roll film holder which hasbeen removed from the body

When the roll film holder for the Pro-S isremoved from the body, the safety deviceprevents its dark slide from being pulled outcarelessly or accidentally. However, if youdesire to pull it out, it can be pulled out byusing your fingernail tip to press the darkslide lock release lever (40) on the bottomof the outer cassette.

Releasing the lens shutter which hasbeen removed from the body

It is advisable to release the shutter whenthe lens is not to be used for a long period.To release a lens shutter which is removedfrom the camera body, turn the cockingpins (56) clockwise, while pressing theshutter lock pin (55) with a finger. Thecocking pins should be turned all the way;do NOT leave the pins turned only halfway..

Shutter testing when the film isloaded

When the shutter is cocked, the dark slideis slightly pulled out (approx. 1/4 in.) andthe shutter release button is pressed, theshutter can be released without exposingthe film in the roll film holder to light. Thisoperation can be utilized for shutter testingprior to photographing.

* When pulling out the dark slide. stop pulling at apoint where the entire triangular hole on the dark slidebecomes visible. If the shutter is released when thedark slide is pulled out beyond that hole, the film willbe exposed to light.* When the shutter is released, a red mark appearson the exposure counter.* When taking the first photograph subsequent tothis test, cock the shutter in the multiexposure condi-tion, and pull out the dark slide. For taking picturesfollowing the first one, restore the multiexposure leverto its normal position and continue photographing.

0 Special Pointers on Using the Mamiya RB67 Pro-S

Various safety interlock devices are provided for theMamiya RB67 Pro-S to eliminate failures through care-lessness. When the shutter is not released, or when thelens or the roll film holder cannot be removed, do nothastily concluded that this indicates a camera malfunction.Ascertain the following conditions. The Instruction Manualpages covering these situation are indicated in paren-theses.

l Shutter release button cannot be depressed l Lens cannot be removed(1) Is the roll film holder loaded with a roll of film and has the film

been advanced to the first exposure?When shutter releasing is desired without loading film, by slidingthe multiexposure lever forward and setting the shutter cockinglever and pulling out the dark slide, the shutter can be released.(P.17)

(2) After the shutter was released during ordinary exposure (not undermultiple exposure), did you advance the film?Advance the film with the film advance lever.

(3) Is the mirror set?Set the mirror by pressing down the shutter cocking lever.

(4) Was the dark slide drawn out?Draw out the dark slide.

(5) Is the shutter release button locked?

Press down the shutter cocking lever. Set the mirror and theshutter. (P.13)

l When mounting the film holder, the slide lock cannotbe moved

While pressing the slide lock release lever, move the slide lockto the left. (P.16)

l Roll film holder cannot be removedAfter inserting the dark slide, operate the slide lock.

l Regarding the mirror release operating knobTurn the shutter release lock ring counterclockwise and align itwith the white dot. (P.13)

(6) Is the revolving adapter turned up to the click stop position?Turn the adapter until it stops with a click. (P.15)

(7) Has the slide lock on the revolving adapter stopped halfway?Move the slide lock up to the position where it stops. (P.16)

Normally align the knob with the red dot. When it is aligned withthe MIRROR-UP index mark, and merely the shutter release but-ton is pressed, the mirror and the light baffle will operate, but noimage will be recorded on the film. (P. 29)
