0 Features of Mamiya RB67 Pro-S
The Mamiya RB67 Pro-S is a unique, high-grade,

reserved for headlines and explanatory notes, s o that the entire
picture format can be fully utilized.

2. Attach the roll film holder and slide both
slide locks firmly in the direction of the arrow
mark.
(; If the slide lock of the revolving adapter
is not pushed fully in or out, the shutter will
not be released because of the shutter
locking safety device. Always operate the
slide lock securely.
* If closing the lower slide lock is neglected, the safety device of the Pro-S holder
will prevent the dark slide from being removed.
* If the dark slide is completely inserted,
or if the film is not loaded, the shutter release button cannot be pressed, leading to
picture-taking failure.

Detaching the roll film holder
1. Insert a dark slide in the roll film holder.
Two white lines on the side of the holder
indicate the position of the inserting slit.
2. Remove the roll film holder by sliding
both slide locks (29) in the opposite direction to the arrow mark on the slide lock.
NOTE:
Since a coupling device for
double-exposure prevention is
adapted for the Pro-S roll film
holder, the shutter cannot be
released if the film is not loaded.
* If the dark slide is not inserted, the slide
lock 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 automatically disengaged, and the slide locks can
be slid without pressing the release levers.

focusing knob, adjust the focus and compose the picture.

0 Distance Scale
Focusing knob fixing
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.
23
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.

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.
24
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.

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


Exposure compensation for close-up photography
Maximum close-up photography table
(with bellows fully extended)
The lens-to.-subject distance represents the distance of the su
edge of the lens barrel.
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.
25
from the front
* 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).
 Attaching and detaching the auto extension tubes
Attaching and detaching the auto extension
tubes is accomplished in the same manner
as with the lens. When initially mounting a
lens to the extension tube, cock both the
lens and the tube.
* The auto extension tubes couple with
the automatic diaphragm of the lenses.
NOTES
1. For exposure compensation, refer to the
following table. Reading of the exposure
compensation scale differs from that when
not utilizing extension tubes.
2. For close-up photography, we recommend independent mirror-releasing prior to
each actual photograph. This omits or minimizes any residual camera body movement
due to mirror action.
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.
26
 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.

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..
When the shutter is cocked, the dark slide
is 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 roll 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
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
