Features of Mamiya RB67 Pro-S

The Mamiya

RB67

Pro-S is a unique, high-grade,

7cm lens-shutter type, single-lens reflex camera

developed to offer excellent picture quality and easy

handling. Mamiya feels confident that the extensive

versatility and capabilities of the Pro-S will meet and

satisfy the requirements of all photographers.

1. Rational 6 x7cm format

Since the 6 x7cm format covers an area 4.5 times the 35mm

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

strates

superb results in color photography. The ratio between the

length and width of 6 x7cm 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,

that the entire

picture format can be fully utilized.

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

image

Since parallax-free focusing in the outstanding feature of the

single-lens reflex camera, speedy camera operation is possible

through brilliant, precise 6

7cm picture composition.

3. Excellent Mamiya Sekor lenses

Mamiya Sekor lenses boast excellent image rendition and color

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

to lenses are available.

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 flash

photography

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 multiexposure

devices

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 changed

over 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 adapter

When the revolving adapter is turned up to 90”, horizontal format

picture

index red lines appear (or disappear), presenting proper

picture

composition.

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,

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 finders

A 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 capacity

Camera component parts are capable of demonstrating their

functions within

a wide temperature range

from

approximately 120°F

5OF

(5OOC

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.

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 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 hood

Available 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 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.

16. Accessory shoe

An accessory shoe is provided for convenient use when mounting

the clip-on-type flash unit.

19. Unique safety devices

Various safety devices

eliminate

possible photographic failures.

20. Complete set of accessories

Availability of a complete set of various accessories further aug-

ments photographic

possibilities

and camera versatility.
