Most interchangeable compact 70 mm cassette loading roll film holders pres-
ently available have a common potential problem. A partially exposed roll
of film that  is left in the holder may tend to take a "set" over the curved
roller in front  of the pressure plate. This could result in the next frame
advancednot being flat against the pressureplate and thus part of the image
may be out of focus. The usual common solution for this situation is to wind
off one blank frame to get past the "set" curved part of the film. In continu-
ous shooting, however, there is no problem whatsoever.
Mamiya has devised an accessorythat will minimize this potential occur-
rence. The Suction Bulb supplied with the holder that can be attached to the
Film Holder and squeezedto help assureflatnessof the film plane.

Of course, if  it is known that the roll of film will not be finished for some-
time, the film can be manually advanced severalframes, the back opened,
and the film cut to remove the partially exposed cassette.This is explained
in detail on page 10.


o Attaching the holder
1. Before attaching the holder, be certain that the upper and lower Slide
Locks (A) are on the left end of the indented portion when viewed from
behind the camerabody. (Fig. 1)
Note:
Should either Slide Lock be moved to tho right while nothang is attached to
the Revolving Adapter, the Slide Lock ReleaseLever (Bl will sngage and the
Slide Lock  will  not movo.  lf this happens, press the Release Lever (B) and
roturn the Slide Lock to the open position.
2. Attach the 70 mm Film Holder and slide both Slide Locks firmly in the
direction indicated by the arrow. (Fig. 2)
*    lf the Slide Lock of the Revolving Adapter is not pushed fully in or out,
the shutter will  not release because of the shutter locking safety device.
Always move the Slide Lock until  it stops and locks.

*    lf the lower slide Lock is not closed, the safety device of the holder will
prevent the Dark Slide from being removed.
 *    lf the Dark slide is completely inserted,or  if the holder is not loaded, the
Shutter ReleaseButton cannot be pressed.
o Detachingthe holder (Fig. 3)
1.  Insert the Dark slide in the Film Holder. Two white lines on the side of
the holder indicate the position of the inserting slit.
2. Remove the Film Holder by sliding both Slide Locks in the opposite
direction indicated by the arrow on the Slide Lock.
 *    lf the Dark Slide is not inserted, the Slide Lock will be locked by the
safety device, and the Film Holder cannot be detached.
*  When a Dark Slide is completely inserted,the Stide Lock ReleaseLever is
automatically disengaged,and the Slide Locks can be moved without press-
ing the releaselevers.
o When desiringto releasethe shutter with an unloaded
  Film Holder (Fig.a)
Move the Multiple Exposure slide completely to the left so that the red dot
becomes fully visible. The shutter can now be releasedafter setting the Shut-
ter Cocking Lever.
*  when the Dark slide is completely inserted, the Shutter ReleaseButton
will be locked. Therefore, either remove the Dark Slide or draw  it outward
to a position where the entire triangular opening in the top center of the
Dark Slide becomesvisible.
*  The sequence that these two steps are done in does not matter.

the cap (Fig.9). Care should be taken not to bend the portion (B) of the
cassette in order to prevent the possibility of a light leak or film damage.
 lf the portion  (B)  is accidentally bent while removing a cap, be sure to
restraightenit before loading the cassettewith film.
4.  Pull out a small amount of film from a loaded cassetteand wrap the tip
of the film, emulsion-sideup, half way around the empty Film Spool and
fasten it in place with the Film Clip (A). The emulsion must be wound to
face the insideof the take-up spool. (Fig. 10)
5.  Insert Film Spool with film attached into the empty cassetteand securely
attach the cassettecap, making sure the Film spool freely rotates. (Fig. 11)
6. Place the loaded cassette (c), emulsion-sideup, into the left-hand side
compartment of the Film  lnsert, as indicated by the diagram appearing
inside the Top Cover of the insert. lFiS.'l2l
7. Swing the empty cassette (D) below and then above the Film lnsert so
that the film travels, emulsion-sideout, over the pressureplate. Next attach
the cassetteto the Take-Up stud of the right-hand compartment of the Film
I nsert.
8. Slide the Bottom Cover Guide Pin (16) into the opening of the Bottom
cover, and after pushingthe Bottom coverall theway in, lock it in place by
turning the Lock Handle (9) clockwise,aligningthe white index line with the
white alignmentdot. (Fig. 13)
9. Gently wind the Film Advance Lever to take up the film slack and see
that the film perforations are properly engagedin the film sprockets (15).
10.with the left hand, hold the dark slide section of the Film Insert case
with the Alignment Dot  (2) upwards, and fit the four corners of the Film
Insert over the dark slide section (Fig. 14). After securely fitting the dark
slide section and Film Insert together, close the case. (lf either the Film
Insert or its caseis upsidedown, they can not be fitted together).
11. while firmly holding the Back cover shut, push in the Back cover Latch

o Film winding for first exposure(Fig. 16)
By winding the Film Advance Lever until it stops,the figure "l"  will appear
in the Exposure Counter Window (6) -  tne red warning signal indicating in-
complete film winding will disappear- and the film will be positionedfor
the first exposure.
*  Unlessthe Exposure Counter advancesfrom S to 1, the shutter cannot be
released.
o Film advancing
1. Pull out the Dark Slide and release the shutter. When the shutter is
released,the red warning signal appears in the Exposure Counter Window,
indicatingthat the film is exposed.
2. When the shutter is released,the Film Wind-Stop mechanism is also auto-
matically disengaged,and the film can be advancedto the next frame. When
film  is advanced one full frame, the numeral in the Exposure Counter
Window is advanced,and the red warning signaldisappears.
                                               *  Unless the exposed film frame is ad-
                                vanced, the shutter can not be released
                             because of built-in double-exposurepre-
                                 vention.
                                               *  Shifting to multiple exposure photo-
                              graphy is possible.Refer to page 12.
                                               *  Even if the film has been completely
                              advanced,the shutter cannot be released
                                                            if complete return of the Film Advance

                               another object.W          *  Wind the Film Advance Lever gently
                                     to avoid film winding problems.
                                               *  Although  the  Film Advance Lever
                               cannot return until  it is first wound ap-
                                proximately 70o,  it can be moved in
                                 several short, definite strokes to com-

when the holder is used on the Mamiya Universal, or when  it  is desired to
 wind the remaining unexposed film into the holder.
 3. when using a standard fifteen (1b) foot cassette,it  is possible to take
 severalexposures after the fixed number of s4 exposures.hasbeen taken.
 Also, when using a specially loaded cassettewhere the film length is more
 than fifteen (15) feet, you may take over 54 exposures.In this instance,the
 exposure counter numerals will advance up to 65 (55 to 65 are presentedin
green).
4.  At the end of the roll, the pressureon the Film Advance Lever will dis-
appear. To prevent light streaking, remove the cassettefrom the holder just
after the pressureon the Film Advance Lever hasdisappearedto prevent the
film from being completely wound into the cassette.
o Removingexposedfilm
 1. Open the Back Cover and remove the Film Insert.
2. Turn  the Bottom  cover  Lock Handle counterclockwise; remove the
Bottom Cover, and take out the cassettes.
 *   Remove the exposed (take-up) film cassette from the film holder in as
dark a place as possible.
 *   since fogging or  light streaking may occur on the last several frames if
you take pictures until the end of the roll of film and wind  it completely
into the cassette,it is recommended that you wind off severalblank frames
on the end of the film  after 5b exposuresshows in the Exposure counter
window.   lf  the film  is wound completely into the take-up cassette light
could enter the film  slit and fog some of the end of the film. Therefore, it
is recommendedthat a short piece of film shquld be left protruding from the
cassetteto minimize the possibility of fogging.when the possiblefogging of
even the  last few frames must be prevented, remove the take-up cassette
from the 70 mm Film Horder in a darkroom, or a changing bag, and prace
the cassetteinto a sealedlight-tight container.
"  Upon opening the Back cover, the Exposure counter  will return to s
(Start).
*    lf s does not appear in the Exposure counterwindow,   it indicatesthere
is film in the holder.

o Suction Bulb (Accessory)
The limited depthof-field encountered when shootjng with the lens wide
open, or when shooting close-ups,or when shooting a large group of people,
makes absolute flatness of the film plane necessary.Proper use of the Suc-
tion Bulb helps assureflatness of the film plane, thereby offering corner-to-
corner sharpnesseven under the most diff icult photographic situations.
The Suction Bulb does not function when the film is not loaded.
Usingthe SuctionBulb
 1. Remove the Bulb ReceptacleCover Q2l bV pulling it out and store it in
a safeplace.(Fig. 17)
2.  Insert the Coupling Tip of the Suction Bulb Tube (25) securely intothe
Suction Bulb Receptacle(21). (Fig. 18)
3. Before taking the picture, squeezethe Suction Bulb (23). The bulb will
remain compressed(Fig. 19). Trip the shutter while the bulb iscompressed
(at this time, the film is held flat againstthe pressureplate by suction).
4. The Suction Bulb will return to  its normal, round, bulb shape when the
Air  f nlet Button (24!. is pressed.
*  The Suction Bulb is functioning only when it remainscompressed.When
returned to  its normal bulb shape,the film is no longer held againstthe pres-
sure plate by suction. Therefore, before tripping the shutter, be certain that
the bulb is compressed.lf  it is not, squeezethe Suction Bulb once again.
*  Although  it  is possibleto advance the film with the Suction Bulb com-
pressed,the back of the film may be scratched.To minimize the possibility
of scratches, return the bulb to normal by pressingthe Air  Inlet Button
before advancingthe f ilm.
*  When attaching or removing the Suction Bulb Tube from the 70mm  Film
Holder, handle it only by its Coupling Tip. Do not try to remove the tube by
pullingon the tube itself.
*  When the Suction Bulb is not in use, be sure to replacethe Bulb Recepta-
cle Cover to prevent dust or dirt from entering the film holder.

. DarkSlideHolderSlot (FaS.22l
 After the Dark slide  is removed, it can be safely stored in either the Dark
 Slide Holder slot  (10) on the Film Holder, or inserted into the place pro-
 vided for  it on the left-hand side of the camera body.
o MemoGlip (Fig.22l
The film box top will  fit  into the Memo Clip (8) and serve as a film  re-
minder.
o Removingthe dark slide of the film holder when it has
  been removedfrom the body (Fig. 23)
When the film holder is removed from the camera body, a built-in safety fea-
ture prevents the Dark Slide from being removed carelesslyor accidentally.
However, if you desire to remove it,  it can be pulled out by using your
fingernailtip to pressthe Dark Slide Safety-catch(4).
o Shutter testing when the film is loaded (Fig.24l
When the shutter is cocked, the Dark Slide slightly pulled out (approx. 1/4
in.) and the Shutter Release Button is pressed,the shutter can be released
without exposing the film in the Film Holder to light. This operation can be
utilized for shutter testing prior to photographing.
*  When pulling out the Dark Slide, stop pulling at a pointwhere the entire
triangular opening on the Dark Slide becomes visible. lf the shutter is re-
leasedwhen the Dark Slide is pulled out beyond that opening, some of the
film will be exposedto light.
*  When the shutter is released,a red warning signalappearsin the Exposure
Counter Window.
*  When taking the first photograph subsequentto this test, cock the shut-
ter after moving the Multiple Exposure Slide to the left, and pull out the
Dark Slide. After the first exposure,be sure to return the Multiple Exposure
Slide to its normal position.                H

Whenthe 70 mm Film Holderis useUon the
       earlier RB 67 camerabody                     u'

The 70mm  Film Holder functions in the same manner on both the RB67
and the Pro-S with the exception that there is no built-in double exposure
 prevention on the earlier (non-Pro-S)model of the RB 67.
    Whenthe 70 mm Film Hofderis usedon the
    MamiyaUniversal

Attaching the holder to the camera
 First attach the G-Adapter to the camera back and slide the upper and lower
Slide Locks (A) on the G-Adaptercomptetetyto the teft. (Fig.25)
Attach the 70 mm Film Holder to the G-Adapter, and secure it by pressing
the upper and lower Slide Locks completely to the right.
 lf  it  is difficult  to move the slide Locks because of the limited space be-
tween the camera body and the Film Holder, an object such as a pencil may
be usedas an aid. (Fig. 26)
The Slide Locks will be easy to move if the Film Insert Case is first attached
to th-e G-Adapter; the Film Insert can then be placed into its case after ad-
justing the slide Locks. lf the lower slide Locks are not pushed all the way
in, it will be impossibleto remove the Dark slide. Be sure all the slide Locks
are pushed until completely seated.
*   when the 70 mm Film Holder is used on the Mamiya universal, double
exposure prevention and automatic release of the film wind-stop do not
f u nction.
To releasethe film-wind stop, move the Film Wind-Stop Release(7) to the
left. when the lever is moved, a red warning appearsin the Exposure counter
window, the wind-stop is released,and the film is ready for winding.
*  Remove your finger from the Film wind-stop ReleaseLever during film
advancing.

An Extension Eyepiece (magnification of 0.75 X)  is availablefor use with
the 70 mm Film Holder. Even with the holder attached to the Mamiya Uni-
versal camera, the entire field of the viewfinder is clearly visible when the
 ExtensionEyepieceis used.
To attach the Extension Eyepiece to the camera, merely unscrew the Eye-
piece Retainer Ring of the camera by turning counterclockwise,and then
screwin the Extension Eyepiece in its place.
 In addition to being a necessaryaccessoryfor the 70 mm Film Holder, the
Extension Eyepiecewill also prove to be a valuableaid when used with other
Mamiya PressFilm Holders.
o Care of the Film Holder
To prevent possible scratchesfrom appearing on the film,  all parts of the
Film Holder should be kept clean. A blower and/or soft brush should be
used to remove dirt from the Film Insert and Film Insert Case.The rollers
appearing on both sides of the film plane, beneath the Dark Slide, are of
extreme importance. They should always be kept clean, and should freely
rotate. Protect your Film Holder from dirt and rough handling.
o 70 mm Film Cassettes
Keep the felt lips of the cassettesclean. Becausethe accumulation of dirt on
the felt lips may causescratcheson the film, be careful when using a cassette
more than once. TO MINIMIZE THE POSSIBILITY OF SCRATCHING OR
