1.4 Screen Calibration
Having a properly calibrated monitor is a critical factor when viewing
images. Ensure that the digital viewing conditions are as accurate as
possible. A quality monitor and calibration tool should help guarantee
that displayed images on a screen are precisely rendered. Once a
monitor has been calibrated; the color and brightness controls should be
locked to prevent inadvertent changes.
Hardware-based monitor calibrators are now available at reasonable
prices. The process is simple, quick and enables images to be viewed
with confidence. Many higher level monitors have internal calibration
software that works with professional calibration devices for ultimate
accuracy.11
2.0 The 645DF
+
Camera
and Credo Digital Back
System
The Mamiya Leaf Camera system is created to provide as much flexibility
and openness as possible. Follow the instructions below to setup and
use your Mamiya Leaf camera system.
2.1 Charging the Batteries for the Credo Digital Back
Charge the batteries as soon you unpack the camera system.
Although only one battery can be used in the Leaf Credo back at a time,
it is recommended to charge both batteries fully before you start.
Always keep a battery in the Leaf Credo back even when shooting
tethered to a computer via a FireWire or USB connection. Go to page 80
for more details about charging the battery while tethered to a computer.
The battery charger can adapt to voltages within a range of 110 to 250
volts. It comes with an international set of power adapters. Select the
appropriate one that fits your outlet and slide it in from the top to mount
it in place securely.
Connect the unit to the outlet and charge the batteries (approximately
2.5 to 3 hours).
Purchasing Extra Batteries
The Leaf Credo back comes with two batteries (2900 mAh). You can
purchase additional batteries or use Canon BP 915 batteries.
Some third party batteries may not fit into the digital back’s battery
compartment due to differences in the tolerances. Do not try to force a
battery into the compartment. When pressing the battery release button
it should slide in without being hindered.
Warning!
• Only use the charger to charge the specified batteries.
• Do not allow charger to get wet or exposed to moisture.
• Keep the charger out of reach of children.
• Once charging is completed, unplug the charger from power source.
• Only use the original mains adapter, 12V DC or car lead.
• Never apply excessive force when connecting or disconnecting a
battery or contact plate.
• Keep all contacts clean.
• Do not force down any of the contacts.
• Do not short-circuit the contacts.
• Never store the battery connected to the charger for an extended
period of time.
• Do not expose to excessive heat or naked flame.
• Do not dismantle or carry out any alteration to the product.
• Do not attempt to eat or swallow the battery.12
2.2 Batteries for Camera

2.3 Sleep Mode
The camera’s power is switched on when the shutter release mode
selector is set to S, C or M.UP . In order to prevent the camera’s batteries
from discharging, sleep mode is automatically entered if no operations
are performed for a specific period of time while the power is ON (with
exposure metering status maintained).
In sleep mode, operating the shutter button or a function setting button
restores power ON status.
In sleep mode, the external LCD screens are not active, only the marks
shown in the figure are displayed. (These marks appear in program AE
mode.)
1. Battery life of the originally supplied batteries is dependent on storage
conditions.
2. Blots and fingerprints on the battery terminals may cause a loose
connection and corrosion. Wipe them off 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. An 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 if you plan on not using
the camera for a long time.
7. Replace the batteries with new ones as soon as they are exhausted.
Liquid leakage from the battery can damage the camera.
8. Read the warnings on the batteries for their handling.
For the purpose of the descriptions and explanations
provided in these instructions, it is assumed that the
camera’s power is on.14
2.4 Attach and Remove a Lens
1. Remove the front body cap in the same way that you would remove
a lens; push the lens release button
A
backward and then turn the
front body cap or the lens itself counter clockwise and lift out.
2. Align the white alignment dot of the lens B (on the shiny flange) with
the camera’s white dot C . Mount the lens and rotate it clockwise
until it clicks into place.
3. To remove the front lens cap, squeeze the shiny sections together
and lift out (see image far left). To remove rear lens cap turn it
counterclockwise.
Remove a Lens
Slide the lens release button
A
back, rotate the lens counter clockwise
until it stops, and lift it off. After removing the lens from the camera body,
protect both ends by attaching the caps.
Note: Oil, dust, fingerprints or water on the electronic contacts could
result in malfunction or corrosion. Wipe such impurities off with a clean
piece of cloth. Do not tap the distance ring or other rotating parts when
attaching the lens. When installing a lens, do not press the lens release
button.

Attach a Leaf Shutter Lens
Leaf shutter lenses are equipped with an internal shutter. Leaf shutter
lenses are capable of high shutter speeds 1/800 sec or 1/1600 on Leaf
Credo series backs with flash synchronization, which is particularly useful
for fill-in flash photography in bright ambient shooting conditions.
When a leaf shutter lens is attached and the leaf shutter is used, the
letters LS appear in the main LCD screen.
2.5 Adjusting the Strap

2.6 Attaching the Leaf Credo Back
The Leaf Credo back is fully integrated with the camera body and
functions as a part of the whole camera system.
Ensure that the Mamiya 645DF
+
camera mirror is up and the shutter is
open when there isn’t a digital back attached.
When attaching the Leaf Credo back to the camera body the shutter
closes and the mirror comes down.
First remove the cover. Next, ensure that the bottom part of the Leaf Credo
back is placed correctly in the lower locking mechanism on the back of
the camera body before the upper locking mechanism A + B is pressed
together. Failure to do this can cause an error with the camera body where
the shutter continuously opens and closes. If this occurs, remove the Leaf
Credo back. Make sure the camera body is powered, press the digital back
release button 2 while mounting the digital back, lock the mounted back
by sliding the digital back lock 1 toward the camera.
Be aware that the shutter should be in the correct starting position
(shutter open). If this is not the case, attach and remove the Leaf Credo
back again to make sure that the camera body gets in the correct
starting position.
Remove the Leaf Credo back by sliding the digital back lock 1 , pushing
in the digital back release button 2 , and by gently pulling away the top
of the back first. Be careful with the contacts and protective glass on
the back. Your Leaf Credo back should always be protected by its plate
when it is not attached to the camera.17

2.10 The Buttons on the Back
The Credo is equipped with four soft buttons. The buttons change
function to match the menu shown on the screen.
2.11 LED Lights
Credo series digital backs feature two LEDs. One is located next to the
on/off button and the other is inside the CF card compartment.
The red LED indicator located next to the CF card slot (under the cover)
is assigned to indicate CF card activity only. Do not remove a CF card
from the card slot when this red LED is on. Removing a CF card when
the red LED is on can damage the formatting of the card, and images or
data might be lost or corrupted.

2.12 Setting Date and Time
Date and time parameters are set and controlled via the Leaf Credo
back’s Menu system.
If the Leaf Credo back has been without power for a long period of time,
it automatically asks you to set the time and date on the next occasion it
is powered up.
Tap the screen and scroll through the numbers to attain the appropriate
date and time.
The time and date is applied to the EXIF data in all files captured with the
Leaf Credo back.
2.13 Setting Diopter
Look through the viewfinder and make sure that the focus frame
(rectangle with circle) is in sharp focus. If it is not, turn the diopter
adjustment dial in the “–” direction if you are nearsighted or in the “+”
direction if you are farsighted. If this is not sufficient you may require an
optional diopter correction lens. Check the table for possible diopters.
Point the camera at a bright, plain object such as a white wall when
making this adjustment.

Eyepiece and the Diopter Correction lens. (Turn the camera upside
down to gain easy access to it). Now remove the rubber Eyepiece by
sliding it upwards
2. Remove the lens supplied with the finder by pulling it downward.
3. Remove the existing diopter by sliding downwards using the fingernail
groove and detach. Insert a new diopter by aligning it to the base
of the diopter holder and sliding it upwards into place. Finish by
reattaching the rubber eyecup.
2.14 Eyepiece Shutter
Close the eyepiece shutter when there is a strong light source behind
the camera or when pressing the shutter release button without looking
through the viewfinder. This prevents exposure error due to light entering
from the viewfinder.
Turn the eyepiece shutter lever in the direction of the arrow.
Notice:
If there is dirt or dust on the lens
surface, remove it with a blower or
sweep it off gently with a lens brush
If there are fingerprints or dirt on the
lens surface, wipe them off with a
piece of clean, soft gauze
Using solvents could discolor the

3.0 Basic Functions
ISO and White Balance
The Leaf Credo back’s Home screen enables quick access to the ISO
and white balance (WB) settings by tapping the screen directly. White
Balance and ISO settings can also be controlled from Capture One if you
are working tethered.
3.1 Setting ISO
The default ISO setting is 50 for all Leaf Credo series models. Remember
that the higher the ISO setting, the higher the degree of image noise. The
camera system together with Capture One software deliver a powerful
noise reduction performance although it is possible to still see some
noise at the higher sensitivity settings.
Tap the ISO icon on the Leaf Credo back’s Home screen. You are
presented with the back’s ISO spectrum. Tap the screen to select the
desired setting. A green frame surrounds the selected ISO and you are
returned to the Home screen.
Find out more on ISO operation on page 57.
3.2 Setting White Balance
The default WB setting is Auto. The camera calculates a white balance
based on the information in the image. Auto WB is appropriate for most
applications where the subject color and lighting are consistent.
Tap the WB icon on the Home screen. You are presented with the back’s
white balance settings. Scroll left or right and tap the icon to select the
desired setting. A green frame surrounds the selected WB and you are
returned to the Home screen.

conditions. This auto mode is best suited for general photography or
for novice photographers, as it leaves the user free to concentrate on
framing and capturing the subject.
Av: Aperture priority AE — Set the desired aperture and the camera
selects the correct shutter speed. Use this mode to control depth of field.
Tv: Shutter priority AE — Set the desired shutter speed and the camera
selects the correct aperture. Use this mode to stop motion.
M: Manual mode — Set this mode to use special combinations of the
aperture and shutter speed.
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 metered in the S mode. The A-S mode automatically
switches between these two modes depending on the contrasts in
the picture.
Notice:
When a polarizing filter is used, ensure
that a circular polarizing filter (C-PL) is
used. The correct exposure cannot be
obtained with a normal (linear) polarizing
filter (PL).

Exposure Warnings
Users are warned when shooting subjects that are too bright or too dark
with an inappropriate exposure setting. At such times, when the correct
exposure cannot be obtained, users are alerted by the numeric exposure
display that flashes on the external LCD or on the display inside the
viewfinder.
Warnings that the exposure is outside the metering range
• Program AE (P)
The shutter speed and f-number blink.
• Aperture priority AE (Av)
The shutter speed blinks.
• Shutter priority AE (Tv)
The f-number blinks.
• Manual mode (M)
The exposure metering value difference is displayed.
Average/spot auto
exposure metering
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.
• 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
exposure metering
The average brightness of the entire screen is measured,
emphasizing the center of the screen.
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.

3.5 Focus Modes
To use the Auto Focus function, both the camera body and the lens have
to be set to their respective Auto Focus modes. Auto Focus does not
function when either the camera body or the lens are set to manual focus.
To activate Auto Focus (AF), first select AF on the focusing selector
ring on the lens. Next, adjust the Focus Mode Selector Lever to either
S (single) or C (continuously) Auto focusing on the camera. The Focus
selection ring on the lens can help you to rapidly switch between AF and
M, without having to change your grip of the camera.
The shutter release button has a two-step action. When pressed lightly
it stops at a certain point. In this manual, this position is called the half-
press position. When you half-press this button, the camera functions are
activated. When the shutter button is pressed further down, the shutter is
released. This position is called the full-press position.
1. Aim the camera so that the subject is within the focus frame.
2. Half-press the shutter release button, and focus is adjusted
automatically in AF mode. As default, you can now re-compose your
image without losing the original focus setting, by moving the camera
and keeping the shutter release button half-pressed. When the focus
mark lights up, the subject is in focus.
3. When the focus mark lights up, press the shutter release button
further down to release the shutter. (The focus mark is an illuminated
dot (indicated as this • symbol) at the bottom of the viewfinder display.
See the focus mark in the illustration circled in red).
Out of Focus Marks 
When the picture is not focused the shutter cannot be released when in
single focus mode. Either press the shutter release button again to adjust
the focus or move the camera to change the position of the focus frame.
Lenses without the focus mode selector ring are automatically set to AF
if the camera is set to Auto Focus. Do not touch the focus ring as you
may cause internal damage to the camera Auto Focus motor.
Lenses with the Focus Mode Selector
The focus modes can be switched between automatic and manual
with the selector on the lens when the focus mode selector lever on the
camera body is set to S or C.
Normal Half-press Release position
Full-press29
Single Focus Mode (S)
This mode uses the focus-priority mechanism. The shutter can be
released when the focus mark • in the viewfinder is illuminated. This
mode is suited for still subjects. Focus is locked when the focus mark •
is illuminated in the viewfinder’s LCD.
The shutter cannot be released if the subject is not in focus (if the focus
mark • does not illuminate).
To take another photo with a different composition, take your finger off
the shutter release button then re-press the shutter release button again.
Continuous Focus Mode (C)
In this mode shutter release has priority to focusing. The shutter can
be released regardless of whether the focus mark • in the viewfinder’s
display is illuminated. Focus is adjusted continuously while the shutter
release button is half-pressed. This mode is suited for moving subjects.
Focus is not locked even if the focus mark is lit.
The shutter can be released even if the focus mark is not lit.
Manual Focus Mode (M)
To attain full manual control of the focus function you can change to
manual focus mode in two ways.
1. All lenses: Turn the focus mode selector lever to M (Manual focus
mode).
2. Manual Focus operation for telephoto and zoom lenses: All
newer Mamiya, Phase One and Schneider-Kreuznach lenses can be
switched from Auto Focus to Manual Focus by using the AF ring or
slider fitted on the lens.
For lenses with AF slider, slide the focusing ring on the lens backward
until it clicks. When this is done, the Auto Focus inscription on the lens
barrel is covered and the lens can then be focused manually. For lenses
with an AF ring, simply rotate the AF ring to the MF position to select
manual focus.

Manual Focusing using the Focus Mark (Focus confirmation
method)
Half-press the shutter release button and turn the lens focusing ring to
focus on the subject. The focus mark is illuminated in the viewfinder’s
LCD to signal that a picture is in focus.
If  is lit in the viewfinder’s LCD, the camera is focused on a point
behind the object.
If  is lit, the camera is focused on a point in front of the object.
– Use the focus mark when taking photos in manual focus mode or
when using the M645 manual lens.
– If you adjust focus using the focus mark with an M645 lens, make
sure to open the aperture. You can use this function with the lens set
to f/5.6 or higher.
When Auto Focus Fails
The auto focus function requires contrast in the subject. Auto focusing
may fail to achieve focus with certain subjects described below. In such
cases, either switch to the manual focus mode (and focus manually) or
focus on a more contrast appropriate object at the same distance as
the object you want to photograph, lock the focus using the focus lock
button on the front of the camera body, then take a picture.
• Low-contrast subject (blue skies, white walls and other objects)
• Two or more objects overlapping at different distances within the focus
frame (animals in cages, etc.)
• Subjects with continuous repeated patterns (building exteriors, blinds, etc.)
• Extremely backlit reflective subjects (car bodies, water surfaces, etc.)
• Or when the subject is far smaller than the focus frame
In focus

achieve the desired composition, and release the shutter.
When the focus mode is set at S (Single focus mode) and the focus
mark • is lit, hold the shutter release button halfway down to lock the
focus.
AF Assist Infrared Light
Autofocus can fail when a subject is dark or very low-key. On these
occasions, a red lamp may be activated on the front of the camera when
the shutter release button is half-pressed to assist the camera’s auto
focus function. The AF assist infrared light is emitted only when the focus
mode is set to S (Single focus mode).
Notice:
Effective range of the AF assist infrared
light is limited. It does not reach distant
subjects. — Range:
9 m/29.5 ft (using 80 mm f/2.8 lens)
Use of a lens hood or a bellows lens
hood (sold as an optional accessory)
may interfere with the assist light. It
is advisable to set the focus before
mounting the hood.
The AF assist infrared light can be
disabled. 32

3.9 Exposure Modes
(P) Program AE
The aperture and shutter speed are determined automatically for
the optimum exposure, according to the ambient light conditions.
This auto mode is best suited for general photography or for novice
photographers, as it leaves the user free to concentrate on framing and
capturing the subject.
Alter the shutter speed and aperture by turning the front and rear dials
while the P (Program AE) mode is selected.
Program Shift (PH/PL)
The shutter speed and aperture can be altered by turning the front and
rear dials while the P (Program AE) mode is selected. In order to avoid
blurred images (due to camera shake while releasing the shutter), or
to open the aperture, change to PH (high speed). For slower shutter
speeds and wider depth of field, change to PL (low speed). This function
allows these changes to be made quickly.
Notice:
If a correct exposure cannot be
obtained, the shutter speed and
aperture value blink. In such cases, the
pictures can be taken, but they may be
too bright or too dark.
If the shutter speed and aperture
values blink on the main LCD and
in the viewfinder display when the
program line is shifted, the proper
exposure cannot be achieved.
Select a different program mode.
When the Program line is shifted, the
aperture value changes along with the
shutter speed to maintain the proper
exposure.
Increment of the aperture and shutter
speed can be set at either 1/3- or
1/2-stop.

Shutter Types and Flash Synchronization Options for Shutter Modes38
3.10 Flash Photography
The Mamiya 645DF
+
is equipped with a vertical-travel focal plane metal
shutter and it is also compatible with leaf shutter lenses.
The focal plane shutter provides higher shutter speeds than that of leaf
(central) shutter lenses. Focal plane shutters allow you to shoot fast
enough to freeze moving subject matter. Leaf shutter lenses allow faster
shutter synchronization to flash, making it ideal for freezing subject
movement when using strobe lighting.
The focal plane shutter method allows for shutter speeds of up to 1/4000
sec When shooting at higher speeds e.g. 1/500 sec the two shutter
blades are moving in parallel creating a small slit allowing a small fraction
of light to reach the sensor area of the digital back. When using this type
of shutter it is not possible to achieve flash synchronization greater than
1/125 sec.
A leaf shutter makes it possible to achieve faster shutter and flash sync
speeds. A Leaf Credo series back can sync at maximum shutter speed
of 1/1600 second.
1. A grip type flashgun or a strobe (with electric contacts other than X
contact) can be operated with the Mamiya 645DF
+
by connecting
a sync cord into the camera’s sync terminal. See the note on the
left side of this page about flash units designed exclusively for other
camera makes.
2. Turn the exposure mode setting dial to X (1/125 sec) or M (Manual).
When M (Manual) is selected, turn the front dial and set the shutter
speed to 1/125 sec or slower.
3. Turn the rear dial to set the aperture, and then press the shutter
button to take a picture.
In addition to its standard flash sync system, the Mamiya 645DF
+

features TTL (through the lens), off the film/sensor (OTF) and electronic
flash exposure metering.
Notice:
This camera’s sync contact is
an X contact.
Using flashes designed
exclusively for other camera
manufacturers in the hot shoe
may damage the camera’s
internal mechanisms. In this
situation, use an off-camera
flash bracket and connect a
sync cord to the camera’s sync
terminal.
When using flashes with a flash
duration of 1/500 sec or longer,
set the shutter speed to 1/30
sec or less.
A39
Mamiya 645DF
+
features Through the Lens (TTL), Off the Film/Sensor
(OTF) and electronic flash exposure metering. A flash sensor located
inside the camera body reads the flash light reflected off the surface of
the CCD at the moment of exposure. The sensor is connected via the
Mamiya 645DF
+
’s dedicated hot shoe to a shoe or handle-mount style
Metz flash unit via the Metz SCA 3952 TTL Adapter. Maximum flash
speed is 1/125 second when the focal plane shutter is used, making
daytime synchronization possible.
The ISO of the flash is automatically set through the TTL connection from
the digital back; any adjustment to this is instantly recognized after the
setting is locked and the shutter release is half-pressed.
To utilize the TTL flash feature with all TTL-operable Metz flash units, a
Metz SCA 3952 module is required. See the chart for capability and/or
additional adapters that may be necessary.
The resulting flash exposure automation determines correct flash
exposure and automatically adjusts the output of the flash. It also
automatically corrects for exposure compensation normally required
when using filters, close-up bellows or extension tubes.
1. Mount the SCA 3952 adapter onto the Metz flash, insert fully into the
camera’s hot shoe, and then tighten with the locking knob
A
.
2. Set the exposure mode, and then check the shutter speed and
aperture.

TTL flash
With TTL flash photography, the reflection of the flash is metered and the
intensity of the flash is adjusted automatically, which can mean TTL flash
photography may not be suitable for all shooting conditions. In the cases
described below, we recommend that you use a flash meter to check the
intensity of the flash or use a manual flash setting.
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. For flash photography with a narrow sensitivity latitude

4.0 Introduction to the
Credo Series Digital Back
System Overview
The Leaf Credo series digital back is designed to fit on the Mamiya
645DF
+
as well as several other brands or models of medium format
cameras.
The Leaf Credo series include three different models; the Credo 80,
60 and 40 that feature maximum resolutions of 80, 60.5 and 40 high
quality megapixels respectively. All of the backs have a dynamic range of
12.5 f-stops. The Leaf Credo backs employ both USB 3.0 and FireWire
800 connections, facilitating fast image transfers. All three models also
incorporate a newly designed 3.2 in touch display that features 1.15
megapixel resolution. The wide format display allows for a full 4:3 aspect
ratio VGA resolution image next to a histogram, highlight warning, file
info and touch controls. This touchscreen display is complemented by
Mamiya Leaf’s intuitive 4 soft button navigation.
The following section deals with generic features that are available in all
three Credo series digital back models. 45

4.2 General Hardware Setup
Powering up the Leaf Credo back
After a Leaf Credo back is connected to a camera body, insert a battery,
USB 3.0 or FireWire 800 cable and it automatically turns on. The back is
switched on/off by pressing the power button located at the top of the
Leaf Credo back.
ISO Settings
The Credo 80 back has a default ISO range from ISO 35-800. The Credo
60 and Credo 40 have a default ISO range from ISO 50-800. An ISO
rating can be selected from the menu system (when untethered) or in the
Capture Tool in Capture One Pro software (when tethered).
Shutter Latency
The default setting is Normal Latency, which should remain unchanged
under all ‘normal’ shooting scenarios. Only change the setting to Zero
Latency if you work on technical cameras, large format cameras or
certain manual cameras in special situations.
Double Exposure Protection
It is not possible to accidentally double expose an image by capturing one
shot quickly after another when a Leaf Credo back is used on cameras
such as the Mamiya 645DF
