For years, serious photographers
have desired a camera
which produces the largest
possible negative or transparencyyet is easily hand holdable.
They wished for superb
precision quality, dreamed of
world class lenses,
hoped for controllable
exposure automation, a really
whisper quiet shutter,
a razor sharp focusing finder
uncluttered by too much data - and
unchallengeable accuracy in exposure.

The Mamiya 7 has made
their dreams come true.
Using standard 120 or 220 film,
the compact Mamiya 7 delivers
ideal format 6 x 7cm images.
This large image area can be
viewed with the naked eye,
enlarges to photographic paper sizes
and magazine formats without
cropping and is 4-1/2 times larger
than 35mm images.
Yet the Mamiya 7 handles
like a "35"—and fits
the photographer's hand like a glove.
Truly, a dream come true.

Mamiya 7, the ultimate 6x7 rangefinder camera.
The Mamiya 7 is the only camera in the world that has these exclusive features:
• Ideal 6 x 7cm film format that enlarges to standard photographic and industrial paper size;
without cropping and without wasting film. A size that can be viewed with the naked eye and
that is easy to retouch. • Lightweight, compact, "quick on the draw" and ergonomically
designed to fit your hand like a glove. • Crisp, accurate, broad based, split-image rangefinder,
that is easy to focus, even in poor light. • Bright viewfinder with frame lines that are
automatically indexed to match the focal length of lens in use and that automatically adjust
for parallax. • Interchangeable, world-class Mamiya lenses, utilizing the latest optical glasses
and computer aided design and that take advantage of the camera's short flange focal
distance (there is no mirror box) to reach new heights in lens quality. • Precision, super quie
electronic shutter with speeds from 4 to 1/500 sec, flash synched at all speeds. • Built-in
"dark slide" curtain that permits changing lenses with film in camera. • Precision automatic
exposure meter with manual overrides. • Selftimer (delayed action release) with automatic
turn-off. • Optional external battery case to wear inside clothing in extreme cold. • Optional
panaromic adapter that permits use of 35mm film and yields 24 x 65mm images. • Built with
typical Mamiya quality for hard professional use and long service life.
The 4 3 m m F/4.5
Ultra-Wide Lens for the Mamiya 7
This fantastic ultra-wide angle lens with a 92° angle of field
(comparative 35mm focal length is 21mm) is of unsurpassed
quality. Quality that would be unattainable with tlie typical
retrofocus design required for single reflex cameras (to clear (lie
mirror). Note the picture on pages 2 and 3 which was taken with
tliis lens. The paver blocks backgivund was chosen to demonstrate
the elimination of distortion, so customaiy with many wide angle lense
The Sophisticated Mamiya 7
View/Rangefinder System with AE Metering
Automatic Mode
The bright Mamiya 7 viewfinder incorporates a precison SPD (Silicon Photo Diode) aperture priority exposure meter
system which automatically interfaces with
the electronic lens shutters through gold
plated contacts.
The diagram on the top right shows how the
SPD meters the light in a centerweighted
pattern to optimize exposure for the 80mm
F/4 standard lens. When a wide angle lens
is mounted the system employs a spot
metering pattern. With the telephoto lens
the pattern also considers the surrounding
lighting conditions (lower diagram).
The AE system is thus able to provide excellent exposures for virtually any lighting situation, even with high contrast subjects. An
AE lock is provided to give the photographer
final exposure control.
Manual Mode
All shutter speeds can also be set manually
on the camera's shutter speed dial. In this
mode the exposure meter can still be utilized by observing the LED readouts along
the bottom edge of the view finder.
Exposure Compensation Lever
Exposure compensation from + 2 to - 2 EV
give additional manual control to adjust for
filters or to obtain certain desired effects.

Bright, Crisp Range/Viewfinder
As lenses are changed, corresponding
frame lines are automatically indexed in the
viewfinder. A clear, precise rangefinder
makes focusing easy and fast, even in poor
light.
Along the bottom edge of the viewfinder
LEDs display shutter speeds, over or underexposure situations, battery condition
and malfunctions.

The 65mm F/4
Wide Angle Lens for the Mamiya 7
This lens features a true wide angle lens design with
distortion-free performance that produces results
virtually indistinguishablefromstandard focal length
lenses, yet allows a unique perspective and spatial
relationship of a wide angle view.
The Advantages of the Mamiya 7 Rangefinder Camera
Smaller, lighter, faster, quieter but the same ideal 6x7 format
Why an RF Camera?
Bright Split-Image Rangefinder
No camera can do everything best and the
advantage of groundglass focusing of an
SLR requires a mirror box which adds bulk
and weight and a mirror which causes noise
and image blackout. Rangefinder design
permits a compact, sleek and lighter body,
fast and quiet operation and uninterrupted
viewing. Its much shorter flange focal distance establishes ideal parameters for lens
design, permitting super quality optics such
as our 43mm ultra-wide angle lens.
The bright, crisp Mamiya 7 rangefinder permits fast and easy focusing, in poor light,
and, because of its 60mm base, is very
precise.

The 8 0 m m F / 4
Standard Lens for the Mamiya 7
Mamiya has purposely designed the standard lens for
the Mamiya 7 with a slightly wide angle
focal length (normalfor 6x7 is 90mm) in
response to the wishes of many important pros.
A six element symmetrical lens,
it produces outstanding images.
Mamiya, Master of the Medium,
Leads Again
Mamiya built its first medium format rangefinder camera more than 50 years ago. It
was a folding 6 x 6 with many exclusive features. It pioneered the first 6 x 7 SLR system
camera, the RB67, with revolving back and
bellows focusing more than 25 years ago. It
was followed by the Mamiya RZ67, with
electronic controls, in 1982. Both cameras
became the "workhorses" of the top pros
and made 6 x 7cm the "ideal format" all over
the world and Mamiya the "Master of the
Medium" and the "Medium of the Masters".
The Mamiya 7 Rangefinder camera, with its
sleek and compact form, its light weight of
only 1210 grams (36 ozs), with the 80mm
F/4 lens attached, its ergonomic design that
fits the hand like a glove and its modern gun
metalfinish,will further enhance the popularity of the 6 x 7 format.
Form Follows Function
The integral Mamiya 7 grip makes it easy to
handhold the camera and all its operating
controls—the electronic shutter release
button, the shutter speed dial, the single
strokefilmadvance lever—are conveniently
placed to allow quick shooting without
removing the camera from the eye.
Safety Controls to Prevent Errors
The lens cannot be removed unless the
"dark slide" curtain is in place. The shutter
cannot be released unless the curtain is
open. The shutter can also not be released
if there is nofilmin the camera (to override,
open the back cover) or if the film is not
completely transported. Weak battery power also blocks the release and is indicated by
a flashing LED in the viewfinder.

(LEO (lashing)
"Dark Slide" Curtain for
Changing Lenses
The built-in curtain, activated by
a control on the bottom of the
camera, permits lens change
without foggingfilm.It locks if the
lens is not securely attached to
body.
35mm Panoramic Adapter Kit
The Mamiya 7 is designed to take 35mm
film cassettes when the optional panoramic
kit inserted. It yields spectacular 24 x 65mm
images, an aspect ratio of 1:2.7
*The optional 35mm panoramic kit consists of a panoramic film
mask, a cassette holder, film take-up spool and rewind crank set.
It is easy to attach and remove.
The 150mm F/4.5
Telephoto Lens for the Mamiya 7
This tele lens consists of six lens elements in
five groups and utilizes low and ultra-low dispersion
glasses to yield apochromatic performance of
spectacular brilliance and sharpness.
Rangefinder Camera Design Gives
the Optical Engineer More Creative Freedom
A significant advantage of rangefinder camera design for the optical engineer is the elimination of the mirror box and the resulting
shorter flange focal distance which permits placing the rear lens
element close to the film plane. Various other restraints on lens
design are also removed, providing far more versatility in coming
up with a lens composition that approaches ideal optical theory.
For just one example, lens groups can be positioned in near perfect opposition, doing away with almost all problems of spherical
or chromatic aberration.
The four interchangeable lenses provided for the Mamiya 7 not
only enjoy the benefits of superior design, they also yield the
highest quality of pictorial impact thanks to cutting-edge optical
technologies, manufacturing technologies of unmatched precision and the world's most rigorous, exacting quality tests. The
ultra-wide 43mm lens is the first of its kind for medium-format
rangefinder photography. If offers superb contrast and is unrivaled in its near total freedom from optical distortion.
Mamiya optical systems enjoy an enviable reputation among
professional and serious amateur photographers the world over.
Their secret is comprehensive design and production of the entire optical system, from the camera-lens mount to the individual
elements, from glass selection to polishing, from multi-coating to
final assembly. At every stage of production, Mamiya follows a
single guiding principle: The lens is the life force of the image.

80mm F/4 Standard
150mm F/4.5 Telephoto
This lens offers the same angle of coverage and perspective as a 21 mm lens for conventional 35mm camera systems. But despite this ultra-wide coverage, the compact
lens design yields a weight of just 400 grams, and a front filter size of 67mm. Distortion, so often the bane of ultra-wide optics, is minimized to a remarkable degree—in
fact, even at the corners of the frame, maximum distortion is within 0.04%, while
the optical center has effectively no distortion at all. Chromatic aberration has also
been reduced to unnoticeable levels; maximum fidelity is achieved at the f/8 and
f/11 apertures, but in practical terms the entire range of diaphragm settings provides high quality reproduction. Even at close-focusing distances, this optic outperforms the retrofocus designs of single-lens reflex systems.
Exceptional versatility suited to virtually any photographic demand, this wide angle
is compact and light at just 380 grams, with a filter size of 58mm. Corner distortion
is a negligible 0.08%, and image contrast is extremely high even with the diaphragm
wide open. At smaller apertures contrast reached remarkable levels, maintaining
image consistency over the entire frame. Distortion is minimal even at extreme
close-up, yielding image integrity that holds up for a remarkable range on either side
of the plane of focus for a high-resolution effect. This lens, equivalent to a focal
length of 32mm for 35mm systems, provides outstanding reproduction under either
natural or artificial lighting.
Designed for exceptional compactness and light weight (just 290 grams), this lens
shatters the conventions of standard optics for the medium format. At maximum f/4
aperture, the image is extremely bright yet with virtually no halo. And, through the
full aperture range, the optics retain consistent sharpness and image contrast.
Slightly off the plane of focus, the image circle offers a softer center but still renders
detail of extraordinary resolution. Virtually all optical and chromatic aberration is
eliminated, making this lens a superior instrument for any photographic demand.
Employing an ultra-low dispersion glass to eliminate the varied aberrations associated with telephoto lens design, this optic eliminates all loss of image contrast
even at wide-open aperture settings. Color fidelity is unmatched and astigmatism
is effectively eliminated to assure crisp, bright images of very high resolution for all
types of photo use. Particular attention has gone to preventing coma aberration in
order to maintain image integrity in all situations.
