Assembling

By rotating the bayonet ring counter clockwise until it stops, the red dot of the lens coupling mark on the bayonet ring comes to the top, and the dust cap on the front of the camera body can be removed. At this position of the bayonet ring, insert the lens, matching the red mark on the lens to the red mark on the bayonet ring. Then turn the bayonet ring clockwise, locking the lens in place. Detaching the lens is done in a reverse order to that described above.

PRECAUTION !

Do not touch the pin (9) on the camera body used to couple the lens to the rangefinder. If the lens is changed while a loaded film holder is attached to the camera, be sure to insert a dark slide into the holder.
When using the 100mm f/3.5 standard lens, the lens-shutter assembly must be pulled out from its retracted position before taking general photographs. Grip the lens-shutter assembly firmly, turn it slightly counterclockwise, and pull it out; then, turn it clockwise (in the arrow direction) and secure it in place. If the lens-shutter assembly is left in its retracted position, the coupled rangefinder will not function even when the two images coincide and form a single image. Although the lens is not used for normal photography with the lensshutter assembly in its retracted position, the lens is designed to allow its lens-shutter assembly to remain retracted so that it can be used even when extension rings are used. Also lens retraction is necessary, when using this lens with another camera whose back mount can be extended, when taking a picture with the back mount tilted.

Attaching the Hand Grip

Stabilizing Plate
To attach the hand grip, insert the hand grip into the grip socket (8) of the camera body, and firmly turn the hand grip lock ring (12). Screw the end of the cable release (15) extending from the hand grip into the release socket (25) of the lens-shutter assembly. While dismounting a lens, hang the cable release on the cable release holder (11).
Pull out the stabilizing plate (7) on the bottom of the camera body when resting the camera on a desk, table, or other surface.

M Adapter

Before attaching the back, confirm that both side locking slides (5) are kept at their lowest position. If not, push down the locking slide while pushing in the lock button (5). Align the red point on the M adapter, G adapter, or Polaroid Land camera back (Polaroid Land pack film holder and focusing hood model P) with the red point on the camera body, inserting both sides of the protruded portions to the indented portions on the camera body. Securely push up the locking slide on both sides. While pushing up the slide, the lock button will spring out automatically. The lock button functions to prevent the back from being detached unexpectedly from the camera body. Secure both sides of the back by using the locking slides (5). Do not raise the camera by holding the back in a condition that only one side is secured. To remove the back, depress both side locking slides (5) while the lock buttons (5) are pushed in.
When installing the M adapter on the camera back, the roll film holder for Mamiya Press, focusing screen holder, and so on can be used. To attach the above-mentioned accessories to the adapter, keep the flattened edges of the two locking knobs of the M adapter parallel with the bottom line of the picture format, insert the top of the holder in the upper groove, and push in the bottom: then rotate the two knobs 90 degrees either to the right or left.

G Adapter

Polaroid Land Camera Back
When the G adapter is attached instead of the M adapter, the roll film holder for Mamiya RB can be used. Furthermore, the roll film holder and the focusing panel made by GRAFLEX, Inc., and accessories for the GRAFLOK back can be employed.
Remove the camera back adapter and attach the Polaroid Land camera back directly to the camera body. The Polaroid Land pack film holder and the focusing hood model P are available. With the Polaroid Land pack film holder, use a Polaroid a-exposure, 3 x 4 inch Land film pack. For color photography, use Polaroid Polacolor film type 108 or 668, for black-and-white photography, use Polaroid Land film type 107, 665 or 667 By attaching the focusing hood model P, direct focusing through the ground glass focusing screen of 3 x 4 inch format (ef-

fective picture size of 2 7/8 x 3 3/4 inch, 73mm x 95mm) becomes possible. On the ground glass focusing screen are 6 x 9 and 6 x 7 format indicating lines.

NOTE :

The back attaching system used on this camera is exclusive with Mamiya; thus, do not attempt to use other Polaroid Land camera backs.

Operating the Viewfinder

Selecting Brilliant Frame in the Viewfinder \ Focusing with Coupled Rangefinder
Within the small circle in the center of the viewfinder field two images of the subject are visible. Turn the focusing ring so that these two images coincide. When focusing, coincide the double images at the center of the circle. Looking through the center of the eyepiece is also a key point in accurate focusing. When turning the focusing ring of the lens barrel, be careful not to turn the bayonet ring of the camera body. When the lens-shutter assembly is in a retracted position, or when extension rings are used, the rangefinder will not function even though the double images coincide.
The viewfinder field frame, indicating the field for 6 x 9 and 6 x 7 formats, is adjustable for 100mm, 150mm and 250mm focal length lenses. By sliding over the slide button (28), adjust the number in the indicator window (27) to match the focal length of the using lens. When using the 50mm or 75mm lens, attach the exclusive optical viewfinder of each lens to the accessory shoe on the camera body.

Parallax

Brilliant frames in the viewfinder for 100 mm, 150mm and 250mm lenses are coupled with the rangefinder to automatically correct parallax.
Areas of Viewfinder Field to be Composed
When using Roll Film Holder
When composing the 6 x 9 or 6 x 7 format with the viewfinder frame, employ inside edges of the frame for subjects at close distance; use the outer edges of the frame for subjects further away.

For close range

Distance Range Composed by Brilliant Frame
Focal length of lens 100mm :;;; 150mm

250mm f/5

The 250mm f/5 lens interlocks with the rangefinder from distances of 20 ft (7m) to CO (infinity). When photographing with the 6 x 6 format or 6 x 4.5 format by employing the roll film holder model K, use the attached finder mask. See page 24 for details.
For close ranges, use inside edges of frame 3.5ft to approx. 6ft (2m) (1m) 6ft. to approx. 9ft. (2m) (3m)
For distances further away, use outside edges of frame approx. 6ft. to infinity (2m) approx. 9ft. to infinity (3m) approx. 12ft. to infinity (4m)
For distances further away
Areas of Viewfinder Field to be Composed (cont.)
When Using Polaroid Land Pack 50mm Lens
Attach the optical viewfinder for 50mm lens on the accessory shoe. To correct parallax, turn the knob at the back of the viewfinder and select the same distance scale shown on the dial as the focused distance to subject.

Deciding the Field Composition
Since the Polaroid film pack photographs a wider area than does the viewfinder field frame of the 6 x 9 cm format, compensate the field composition in the following manner, depending on the focal length of the lens to be used. For accurate field composition, use the focusing hood model P. Also, the optical viewfinder model P for 75mm, 100mm and 127mm lenses is available to ensure accurate field of view. The 75mm and 127mm focal length lenses are designed to cover the entire picture area of the Polaroid film pack (3 x 4 ) inch format). However, since other ordinary Mamiya Press lenses are designed for the 6 x 9 cm format, if these lenses are used with the Polaroid film pack, the four corners of the format may be slightly darkened.

75mm Lens

Attach the optical viewfinder for 75mm lens to the accessory shoe. To correct parallax, turn the knob at the back of the viewfinder and select the same distance scale shown on the dial as the focused distance to subject. (The brilliant frame of 3 x 4 inch format indicates the field of view when photographing with the Polaroid Land pack film holder). Attach a finder mask to the viewfinder window of the camera body. For correcting parallax, select the brilliant frame of the viewfinder for 250mm lens, moving your eye about until the brilliant frame is centered in the viewfinder field.

Prior to Loading Roll Film
Set the automatic film wind stop device for the film to be used (120 or 220). Turn the counter change-over knob (R-4) either to the right or left until the figure appearing in the film indicator window (R-5) corresponds to that of the film to be used (120 or 220). Open the back cover By pulling out the back cover latch while pressing the back cover to the holder, the back cover can be opened. Make sure that the correct side of the pressure plate corresponds to the film used. One side of the pressure plate (R-14) is for No. 120 roll film and the other side IS for No. 220. The figure 120 or 220 is indicated on the window of the pressure plate. Reverse the pressure plate if it does not match the film

Removing the Pressure Plate:
Remove the plate by pushing its right side to the left, pulling it out from the plate catch (R-15).

R-4 R-3

Reattaching the plate :
While aligning the upper and lower edges of the plate with the flange, insert the groove into the plate catch (R-13) on the left, then hook the plate catch (R-15) on the right while pushing it slightly to the left Always ascertain that the correct side of the pressure plate corresponds to the film used. Use the convenient film sensitivity reminder dial (R-3) as a memo of film speed in the holder, turning the dial corresponding to the loaded film speed to the red mark.

Loading Roll Film

Avoid direct sunlight while loading or unloading film. Do it in the shade. Pull out the spool change knob (R-10) and place an empty spool into the spool chamber (R-12), Pull out the other spool change knob (R-10) and place a roll film into the film chamber (R-8). By turning the spool change knob either to the right or left after pulling it out, the knob will remain projected. By turning back the knob, the knob will snap back to its original retracted position. The memo clip at the holder back cover can accommodate a film box lid or a blank paper pad for memorandum.

Photographing

Draw out the end of the leader paper of the film, inserting the tip into the slit of the take-up spool. If the spool is not in the proper position or the leader paper of the film is not correctly inserted into the take-up spool slit, film winding cannot be operated properly or smoothly. Wind the film advance lever (R-1) gradually until the start mark on the leader paper aligns with the start marks (R-11) on the holder. Close the back cover and push in the back cover latch, keeping the back cover pressed to the holder. When the back cover is closed, the start marks will be slightly separated; however, this implies no bad effect whatsoever. As the film advance lever is carefully wound, figure 1 appears in the film counter window and the lever stops winding. Even before figure 1 appears in the film counter window, a heavy drag may be felt; however, continue winding until the lever actually stops. Now the first film frame is ready to be exposed Attach the loaded roll film holder to the camera body. Pull out the dark slide (R-6); now, start taking photographs,

After each exposure, by moving the film wind-stop release lever (R-7) in the direction of the arrow, the film can be advanced by turning the film advance lever. Since the film will not advance far enough with only one stroke of the film advance lever, turn the lever until it stops at the second stroke. Winding may be accomplished by moving the lever with several short, definite strokes until the lever stops, although never wind the lever too rapidly. After all frames have been exposed, move the wind-stop release lever (R-7) once, then continue turning the film advance lever until you feel tension on the advance lever lessen as the leader end of the film slips off the spool, finally turning it freely in the take-up chamber. Now open the back cover and remove the film. Fully insert the dark slide when the roll film holder is to be detached or when the lens is interchanged before completing a roll of film, Without a film loaded, turning the film advance lever will not advance the film counter which remains at the start (S) mark. When some other mark is visible in the film counter window, it is your assurance that a film is loaded.

Roll Film Holder Model K

Prior to Loading Roll Film Loading Roll Film
This holder is for taking 6 x 9, 6 x 6 and 6 x 4.5 format pictures with a 120 roll film. The film is advanced by turning the knob. The number of exposures are read on the back of the holder. The memo clip at the holder back cover can accommodate a film box lid or a blank paper pad for memorandum.
Unless photographing in 6 x 9 format, the viewfinder field as well as the picture format of the holder must be changed.
Installing the Picture Frame
Attach the picture frame for 6 x 6 or 6 x 4.5 format into the holder while a dark slide is inserted in the holder. Insert the picture frame so that the folded portion enters the dark slide side (inner side). Insert the claws on both ends into the grooves of the picture frame of the holder while slightly bending the picture frame lengthwise (as shown in the photo).
When loading or unloading a film, avoid direct sunlight. Do it in the shade. By pulling out the back cover latch while pushing the back cover toward the holder, the back cover can be opened. Pull out the spool change knob and place a roll film in the film chamber. Pull out the leader paper of the film, insert the edge of the leader paper into the slit of the take-up spool and wind it around the spool once; then close the back cover. When closing the back cover, press the back cover toward the holder, pushing into the back cover latch. While observing the window for the picture format to be photographed, turn the film advance knob clockwise until figure "1 " appears in the window. Avoid direct sunlight when opening the back window.

This optical viewfinder is especially designed for 75mm, 100mm and 127mm lenses to permit observing an accurate field of view when taklng pictures with the Polarold Land film pack; series 100 or 660 (3 x 4 inch). By attaching the viewfinder to the accessory shoe, and looking through the viewfinder eyepiece, the field of view corresponding to the lens used can be determined. To compensate for parallax, turn the knob on the back of the viewfinder, and set the focused distance to subject.
As a preparatory test when taking an important photograph, make a trial exposure with the Polaroid film pack to confirm lighting and composition of the actual object; then photograph the final picture on roll film and so on. Employing this procedure, unexpected failures can be prevented. In these cases, when placing this format gauge on the photographed subject, composition when photographing with a 6x9 format or 6 x 7 format can be ascertained in advance. Since four corners of the outline indicating the respective size are perforated, the picture can be cut and checked after being marked through these holes.

Focusing Screen Holder

Focusing screen - release lever
This device enables observing the image on the ground glass from the rightangle direction against the optical axis. The right-angle magnifier can be very simply turned upward or sideward, facilitating focusing from any camera angle.
Attaching and Detaching the Right-angle Magnifier Magnifying focusing back
This back is provided with an eye-level, totally enclosed box instead of the right-angle magnifier of the right-angle focusing back. Precise focusing is possible by directly observing the image on the ground glass focusing screen through the eyepiece magnifier. The right-angle magnifier can be removed by swinging it around the bottom of the housing while depressing the button of the right-angle magnifier. To attach the right-angle magnifier, match the projections at the bottom of the magnifier to the holes of the holder, and press in the upper part. When attaching the magnifier, the button does not need to be pressed. The right-angle magnifier can be attached for up, down, right, and left directions. Merely attach it in the direction necessary for the camera angle employed. When looking from above or below, the image assumes the correct right-side-up position, but the right and left will be reversed. When looking from the side, right and left are correct but the image will be upside down.
Since a Fresnel lens is used on both focusing backs, the entire ground glass is very bright, and focusing can be easily accomplished because extraneous light is blocked out. The ground glass has light lines which indicate a 6 x 7 format. After focusing, insert a cut film/plate holder as well as the focusing screen holder for photographing.
Composing the Picture by Ground Glass F o c u s i n g Screen for

Extension Rings

The values in the table represent those when the five extension rings are attached and the lens distance scale is set at the closest distance. The lens-to-subject distance represents the distance of the subject from the front extremity of the lens barrel. Subject coverage is the area of the subject registered on the focusing screen (2 x 3 5/16 in 57 x 84mm).

Precaution

When using many extension rings for photographing in the 6 x 9cm format, certain lenses may produce pictures with darker corners. By stopping down the aperture while looking into the focusing screen, how much darker the corners appear can be observed, The 75mm f/5.6 and 250mm f/5 lenses cannot be mounted with extension rings.
Maximum Close-up Photographing Table

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.

By moving the slide locks (29) on both sides fully to the left, the cap can be removed. * Never push the light baffle (26) on the camera back after removing the rear body cap. If the light baffle is pushed by force, it will cause light leakage or a malfunction.
1. Before attaching the holder, confirm that the upper and lower side slide locks (29) are on the left end of the indented portion when viewed from behind the camera body. NOTE: Should either slide lock be moved to the right while nothing is attached to the revolving 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 position.
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. * 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.
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.
When desiring to release the shutter without loading the film.
In this instance, the shutter can be released by sliding the multiexposure lever of the roll film holder to the front, and by setting the shutter cocking 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 draw it outward to a position where the entire triangular hole in the top center of the dark slide becomes visible. * Either operation of the multiexposure lever or the shutter cocking can be initially conducted.

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. The insert is ready for reloading. * The exposure counter automatically resets to S (start) as soon as the back cover is opened. c When the exposure counter shows other than S, a film is loaded in the holder.
Either film advancing or shutter cocking can initially conducted. However, the recommended sequence of these steps to be customarily observed is: (1) film advancing, (2) shutter cocking, and finally (3) shutter releasing.

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.

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.

Note: Always attach and use the strap so that it and the strap attaching metal are straight. When changing the strap hanging direction, always reattach the strap. * If the strap attaching metal is connected to the accessory shoe side in reverse, detaching will be difficult.

Detaching

Holding the camera by the strap

Three hanging positions

Depending on the attached position of the strap, there are three hanging positions for the strap as illustrated in the photos. Since the strap attaching lug is not rotary, the strap will never become twisted.
T O detach the strap, slide the a t t a c h i n g m e t a l in r e v e r s e direction to attaching, while slightly raising the leaf spring on the attaching metal with a finger tip.
After adjusting the length of the carrying strap, pass your left hand through the strap, and while stretching the strap down from your neck, hold the camera with your left hand. The camera can be held lightly, easily, and securely in this manner.
