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.

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.
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.
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 (3400 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.

L
rechargeable AA batteries. (If you are not using your Leaf Credo on a
Mamiya 645DF+, skip to page 24.)
Li-Ion, NiCd or NiMH batteries should only be used in the camera body if
CF04 is set to the specific type of rechargeable battery used. If using the
Li-Ion battery pack, ensure that the custom function has been set to 2
(Li-Ion rechargeable battery).
Inserting Li-Ion Battery Pack
1. Turn the battery pack lock lever counter clockwise.
2. Slide the Li-Ion battery pack into the camera’s battery compartment.
3. Lock the battery by turning the lever clockwise. Make sure it is firmly
attached.

batteries with new ones.
12
There is little power remaining. Have
new batteries on hand. Camera still
operates.
When the batteries are emptied for
power, batt flashes on the main LCD and
the viewfinder’s LCD when the shutter
release button is pressed.
3. Return the battery holder to its case and lock it by turning the lever
clockwise. Make sure it is firmly attached.
Note: Ensure that the batteries are placed with the correct polarity.
Checking the Battery Power

The camera can’t function without a power source.
Never throw batteries in the garbage. When a battery does not work,
ensure the battery is disposed of in an appropriate manner.
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.
13
For the purpose of the descriptions and explanations
provided in these instructions, it is assumed that the
camera’s power is on.
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.
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

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.
16
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.

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.

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.

3.3 Setting the Shutter Release, Focus, Exposure and
Metering modes
1. Set the Shutter Release mode selector lever to S (single-frame
advance mode).
There are two shutter release (drive) modes: S (single frame advance
mode) and C (continuous advance mode). When set to L the power is
L
turned off.
2. Set the Focus mode selector lever to S (Single focus mode).
There are three Focus modes: S (Single focus mode), C (Continuous
focus mode) and M (Manual focus mode). See page 29 for more
information.
3. Set the exposure mode dial to P (Program auto exposure).
There are four exposure modes:
P (Program Auto Exposure)
Av (Aperture Priority AE)
Tv (Shutter Priority AE)
M (Manual)

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).
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.
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.

Average/spot auto
exposure metering
Center-weighted
average/spot
exposure metering
Center spot exposure
metering
Exposure metering is performed after automatically
selecting average/spot exposure metering.
• Depending on the subject conditions, centerweighted 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.
The average brightness of the entire screen is measured,
emphasizing the center of the screen.
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.
3.4 Measuring Light – Exposure Metering
1. Press button A to adjust the exposure metering mode. There are
three different exposure metering mode options that are displayed
sequentially when either the front or rear dial is turned. Select an
appropriate exposure mode. Your chosen exposure metering mode is
displayed as an icon on the camera’s LCD screen.
2. Press the SET button B or exposure metering mode button A to
enter the setting.
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)

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.
28
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.
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.

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
