Preface

Congratulations on your purchase of the Mamiya 645DF Camera.

	1	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
	2	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.
	3	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.
	4	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.
	5	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).

Battery Power	Battery Care

Remaining battery charge display

●The camera’s power is turned on when the drive dial is set to “S,” “C” or “M.UP.” In order to prevent the camera’s battery power from draining, sleep mode is automatically established if no operations are performed for a specific period of time while the power is ON (with exposure metering status maintained).

●The initial setting for the exposure metering status maintenance period is 15 seconds. It can be changed at any time to a period within 30 sec., 60 sec. using the custom settings. (C-03 on page 84)

●In sleep mode, operating the shutter button or function setting button restores power ON status.

●In sleep mode, the shutter speed and f-number in the external LCDs go off, and the icon shown in the figure is displayed. (This mark appears in program AE mode.)

For the purpose of the descriptions and explanations provided in these instructions, it is assumed that the camera’s power is on.

1.Battery life of the originally supplied batteries is dependant on storage conditions.

2.Blots and fingerprints on terminals may cause loose connection and corrosion. Wipe the terminals before loading the batteries.

3.It is advised to carry spare batteries in remote or foreign locations.

4.Battery performance decreases in low temperatures. Keep them warm when in cold climates or locations.

External battery case PE401 is available as an optional accessory.

5.Store the batteries in a cool and dry place, away from direct sunlight.

6.Remove the batteries from the camera body when they will not be used for a long time.

7.Replace the batteries with new ones as soon as they are exhausted. Liquid leakage from the battery may damage the camera.

8.Read the label warnings of the batteries for their handling.

Attachment

1. Align the lower contact pins of the digital back with the lower contact pins on the camera body. 2. Rest the digital back on the lower ledge of the

camera body so the camera body contact pins and digital back contact pins meet. Hold the digital back lever open (on the right side of ZD backs) or hold down the release button (on the left side of M series backs) then press the upper part of the digital back B to the camera body A.

A click will be heard as the shutter is released, signaling that the back has been

correctly mounted.

Automatic setting of shutter

To protect the shutter curtain, when detaching the digital back from the camera the shutter curtain will automatically open and the mirror will go into the upright position, effectively locking the camera. When reattaching the digital back, the mirror and shutter will return to the set position and the camera becomes unlocked and ready for use.

When batteries are not inserted in the camera body, the shutter cannot be released.

Detaching the digital back

	When detaching the digital back, pull back the
	detachment lever (found on the right side on ZD
	backs) or press the release button (found on the
3	left side of M series backs) and pull away from
	the camera body.

Taking Photos (continued)

3. Set the exposure mode selector dial to “P” (program auto exposure).

There are four exposure modes: “P” (program AE), “Av” (aperture priority AE), “Tv” (shutter priority AE) and “M” (manual mode). “X” is for synchro mode, while “CF” is used to for custom functions.

	Exposure mode		Features
			The aperture and shutter speed are determined automatically according to
			the shooting conditions. This mode is best suited for general photography,
	P	Program AE	since it allows you to concentrate on the shooting. You can change the
			shutter speed and aperture by turning the front and rear dials while the “P”
			(Program AE) mode is selected. (See page 44 and 45.)
	Av	Aperture	Set the desired aperture and the camera selects the correct shutter
		priority AE	speed. Use this mode to control depth of field. (See page 46.)
	Tv	Shutter prior-	Set the desired shutter speed and the camera selects the correct
		ity AE	aperture. Use this mode to stop motion. (See page 47.)
	M	Manual mode	Set this mode when you want to use special combinations of the aperture
			and shutter speed. (See page 48 to 51.)

4. Exposure metering mode is automatically set to average/spot exposure metering before exposure metering is performed.

					There are three exposure metering modes: In
					the “A” mode the average brightness in the
					entire frame is measured with emphasis on the
					center of the frame. The brightness at a
					specific spot in the center of the frame is
CF X	M				metered in the “S” mode. The “A-S” mode
