Preface

Congratulations on your purchase of the Mamiya 645DF Camera.

Mamiya pioneered the 645 SLR system camera three decades ago and the Mamiya 645DF, with its TTL auto-focus, auto-exposure and auto-ﬂash is the latest Mamiya masterpiece and reﬂects its long tradition of medium format camera expertise.

Combining 35mm handling ease and speed but with an image size almost 3 times larger, it is a full-featured camera, utilizing many digital controls and LCD displays, and featuring 19 custom settings for fully personalized digital photography.

Its high-tech focal plane shutter with speeds up to 1/4000 sec. permits ﬂash sync up to 1/125 sec. and has an exclusive “Safety Retraction” feature, which protects it against accidental damage.

The AE Prism Finder with its many features, protected by a sturdy magnesium housing, and also the Power Drive Grip, are now integral components of the die cast aluminum camera body, designed for heavy professional use.

All the many features, safety interlocks and other important information are covered in detail in these instructions. It is imperative that you read them thoroughly before you put your camera to work, in order to ensure proper operation and maximum results.

Special Advice To Professional Photographers

Your Mamiya 645DF is designed for heavy professional use and will give you a long service life if properly maintained. Your camera and lenses have many moving parts which require periodic lubrication. Its electronic components, too, are subject to wear and tear and are affected by ambient conditions like dust, sand, sea air, heat and moisture.

If cameras had odometers like automobiles, it would be easier to specify servicing schedules. May we suggest that if you shoot thousands of images per year, you send your equipment annually for servicing to the Mamiya distributor in your country.

Mamiya 645DF corresponds with digital backs compatible with MSCE (Mamiya Serial Communication of External).

2. Press the SET button B or exposure metering mode button A to enter the setting.

Exposure Metering Modes

Exposure metering is performed after automatically selecting average/spot exposure metering.

• Depending on the subject conditions, center-

weighted average/spot exposure metering is selected automatically, and the correct exposure is measured.

Average/spot auto exposure metering

• Spot exposure metering is automatically selected

when the brightness of the spot exposure metering range becomes darker than the brightness of the entire screen.

• If there is very little difference between the spot

exposure metering value and center-weighted average exposure metering value, the correct exposure level is obtained as the intermediate value.

Center-weighted average/spot

The average brightness of the entire screen is measured, emphasizing the center of the screen.

exposure metering

Center spot exposure metering

The brightness of an area equivalent to 7.6% at screen center is measured, and the exposure is determined. The circle at screen center serves as a general guideline. This mode is suited to measuring subjects with strong contrasts or measuring only screen portions.

Flash Photography

Depth of Field

Depth of ﬁeld (D.O.F.) is deﬁned as the zone of sharpness before and behind the plane of focus. It depends on distance to subject, focal length of lens, aperture setting and distance the lens is focused at.

In addition to visual observation via the depth of ﬁeld preview button, the D.O.F. can be determined by using the depth of ﬁeld scale on each lens. The f/stop numbers appear on both the right and left side of the white index mark in the center of the scale.

In addition to its standard ﬂash sync system, the Mamiya 645DF features TTL (through the lens), electronic ﬂash exposure metering. A ﬂash sensor located inside the camera body reads the ﬂash reﬂected off the sensor at the moment of exposure. The sensor is connected via the Mamiya 645DFs dedicated hot-shoe to a shoe- or handle-mount style Metz ﬂash unit via the Metz SCA 3952 TTL Adapter. Maximum ﬂash sync speed is 1/125 sec., making daytime synchronization possible. To utilize the TTL ﬂash feature with all TTL-operable Metz ﬂash units, a Metz SCA 3952 Module is required. Please see the chart below for compatibility and/or additional adapters that may be necessary. The resulting ﬂash exposure automation determines correct ﬂash exposure and

For example:

(1) When the size of the subject you want to light with the ﬂash is relatively small within the

picture

(2) When the background behind the subject is extremely bright or when there is a strongly

reﬂective object in the background (3) When the background behind the subject is extremely dark (outdoors at night, etc.) (4) When light from the ﬂash is incorrectly directed and falls too widely from the subject.

Rear Curtain Sync Mode

When a moving subject has been shot under this function, the ﬂash of light appears after the moving subject.

Common Sense Camera Care and Practice

Maintenance and care of the camera

• Read instructions before using camera.

• Protect camera against shocks and falls. Use the neck strap supplied with it,

whenever possible.

• Check the batteries frequently and always carry spares. The sealed batteries

supplied with the camera may have been subject to storage conditions which have reduced its service life.

• Be sure to wipe battery contacts before installation and watch correct polarity.

• Battery life differs, depending on frequency of use, type, age, storage condition,

ambient temperature (use external battery case in very cold weather), etc.

• Always remove the battery when camera is not used for a long period of time.

• Always keep covers on lenses and camera body.

• Do not store the camera at temperatures exceeding 40˚C (105˚F) and -10˚C (15˚F).

Also avoid humid or sea air environment.

• Prolonged disuse shortens camera life. Periodically exercise the shutter (at different

speeds), lens diaphragms (at different apertures) and focusing mechanism.

• Protect camera against rain and moisture.

• Do not touch lens surfaces. Use blower or lens tissue to remove dust particles.

• Always test your equipment before going on important assignments.

The Importance of Proper Maintenance

Your camera has mechanisms like shutters and diaphragm blades. They are controlled by gears, levers, springs, and so on. All require special lubrication from time to time. Ambient conditions can also affect these mechanisms, as well as the electronic components and the optical glass of your lenses. We therefore suggest that you have your camera and lenses checked, and if necessary serviced, periodically.
