Instructions
Congratulations on your purchase of the Mamiya 645 PRO
Mamiya pioneered the 6x4.5 film format and introduced the world’s first 645 SLR in 1975. The 645 PRO is the latest masterpiece in this series and incorporates all the latest mechanical, electronic and optical advances. Its external appearance, too, has been modernized and its ergonomic design further enhanced.
We are sure that you will enjoy the many advantages this camera and its accessories offer and want to particularly mention:
The 645 PRO has a built-in self-timer (delayed shutter release) which will also facilitate time exposures. Attaching special leaf shutter lenses will automatically set the focal plane shutter to 1/8 sec. Heavy duty gears connect to the improved Power Drive Grip WG401. This grip also automatically cocks the leaf shutter lenses and permits remote control.
The AE Prism Finder FE401, specially created for this camera, automates exposure and shows LED safety signals. 35mm film holders now come with panoramic adapters. A super fast 300mm f/2.8 APO lens was also designed for this camera.
We are convinced that your camera will serve you well, because we have designed it for heavy professional use. However, we ask you to please read all operating instructions carefully before you put your equipment to work, in order to ensure proper operation and maximum results.
This manual covers the basic camera. Separate instructions are supplied with all system accessories, including lenses,finders, film holders, etc.
For additional information please feel free to contact your authorized Mamiya dealer or the Mamiya importer in your country.

3 x More Negative Area Than the 35mm Format Plus Superior Image Quality From Mamiya WorldClass Lenses
The 6x4.5cm format offers approx. 3 times more image area than the 35mm (24x36mm) format, Man’s vision is horizontal and rectangular.
Film Holders are rectangular and so are most pictures in them. The 6x4.5 format is also large enough to be viewed without a magnifier and its aspect ratio (horizontal / vertical) is ideal, requiring minimum cropping. Mamiya’s high performance medium format lenses assure sharpness and beautiful color fidelity.
Sturdy, Versatile, Safe and Highly Reliable Body 2 - Tailored to Satisfy Pro Needs -
Introduced in 1975 to not only provide an alternative to the 35mm format, but to afford the user with advanced versatility given its much larger format, the Mamiya 645 Series is constantly being upgraded. Elements such as speed and handling plus a host of other special features have been enhanced to satisfy the needs of most demanding professionals.
Two new convenient safety features have been added to the 645 PRO in the form of state-of-the-art optoelectronics which immediately identifies problems with the shutter (i.e. when it will not release) when the AE Prism Finder FE401 is used. Whether these malfunctions develop from failure to draw out the Dark Slide, or if there are problems in film take-up, the LED will indicate the source of the trouble. With these new advancements, Mamiya believes the most demanding pro will be more than satisfied with the new edition 645.
Enhanced Interchangeable Roll Film Holder System
3- Enables Polaroid and Even 35mm Panoramic
Photography -
The 645 PRO features an interchangeable film holder system capable of using a far wider range of roll film holders than before. Depending on the application, the system can be quickly attached to or detached from the camera, ensuring the ability to catch even fast changing scenes. It also features fail-safe devices including, for example, one that warns when you have failed to take out the dark slide when the AE Prism Finder FE401 is being used.

Interchangeable Viewfinders
1. AE Prism Finder FE401
The AE (automatic exposure) Prism Finder FE401 features three modes of TTL metering, including automatic switching from center-weighted averaging to spot metering. It also has a +/-3EV exposure compensation adjustment.
2. Prism Finder PF401
The Prism Finder PF401 is without metering electronics and designed for manual photography mode. Both Prism Finders show an unreversed, upright image and are ideal for eyelevel photography.
3. Waist Level Finder N
The Waist level Finder N is desirable for low angle photography and particularly for horizontal composition. A self erecting hood with built-in magnifier shields groundglass from all ambient light. A built-in sportsfinder permits eyelevel viewing and is ideal for action photography.

Bright, Dynamic Images Visible on the Focusing Screen
- 5 Selectable Types Available -
The 645 PRO can reproduce bright, dynamic and sharp images on the focusing screen, enabling optimum composition to be obtained according to the photographic purpose. In addition, the 645 PRO greatly enhances focusing.
5 types of focusing screens are available to facilitate photographing a wide variety of subjects.
A Comprehensive Series of Interchangeable Lenses 6 - Sharp Images and Outstanding Color Balance -
There are an amazing variety of interchangeable lenses in the PRO 6 x 4.5 format series. Mamiya has concentrated an all-out effort on the systematic production of lenses in an effort to satisfy a multitude of needs. All lenses are multi-coated to eliminate flare and ghosting even under the most adverse light conditions. While the series now also features three leaf shutter lenses, all lenses exhibit the utmost in color balance, high resolu-
tion and crystal clear definition. A feature lens is the new 300mm f/2.8 APO lens which eliminates chromatic aberration and produces photos with the sharpest definition. Given the wide variety of lenses in the 645 PRO Series, they greatly expand the world of images that are possible.
Auto winding with the Power Drive Grip WG401
This Power Drive Grip WG401 has been specially designed for heavy duty, motorized operation with the 645 PRO. It also permits automatic shutter cocking of the leaf shutter lenses and can be remote controlled. Another feature, not available previously is the following:
When attaching a partially exposed film holder (in which the film has not been advanced to a new frame), to the 645 PRO equipped with the Power Drive Grip WG401, a
built-in camera mechanism will automatically advance the film to the next frame, when the shutter release is activated, either on the camera body or on the Power Drive Grip WG401.
New Automatic Leaf Shutter Lenses for added 8 versatility.
55mm (Wide Angle), 80mm (Standard) 150mm (Telephoto) lenses
These lenses are all in Seiko #0 shutter, offer the advantages of syncroflash photography at all shutter speeds 1/ 30, 1/60, 1/125,1/250 and 1/500sec. The optional Power Drive Grip WG401 will automatically cock the shutters as it transports the film and moves the mirror.
The camera’s focal plane shutter must be set at 1/8 sec. for leaf shutter mode operation. The leaf shutter lenses can do it automatically.

10 Other Features

will light a red pilot lampain the frontm of thep camera fori eight seconds and will blink for two seconds before triggering
