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.
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).
• Keep all contacts clean.
Purchasing Extra Batteries
• Do not force down any of the contacts.
The Leaf Credo back comes with two batteries (2900 mAh). You can
purchase additional batteries or use Canon BP 915 batteries.
• 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.
11
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.
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.
2.2 Batteries for Camera
P
M.U
Set the shutter release mode selector lever to L (to turn the power off).
C
S
L
Use the Mamiya Li-Ion rechargeable battery pack, six AA alkaline or
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.
Inserting AA Batteries
1. Lift the battery case lock lever, turn it counter clockwise and pull out
the battery holder.
2. Insert fresh batteries with the + and – ends as shown in the illustration.
The batteries are sufficiently charged.
There is little power remaining. Have
new batteries on hand. Camera still
operates.
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
Set the Drive dial lever to S to turn the power on.
There is very little power remaining.
Camera does not operate. Set the
shutter release mode selector lever to L
(to turn the power off) and replace the
batteries with new ones.
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.
Check the battery condition in the lower left corner of the top LCD
screen.
Always use six new batteries of the same type when replacing batteries.
Do not mix different types of batteries or use old batteries with new ones.
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.
12
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.
For the purpose of the descriptions and explanations
provided in these instructions, it is assumed that the
camera’s power is on.
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.
13
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.

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.

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.
Find out more on White Balance operation on page 58.

Exposure Warnings
Average/spot auto
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.
Center-weighted
average/spot
exposure metering
The average brightness of the entire screen is measured,
emphasizing the center of the screen.
Center spot exposure The brightness of an area equivalent to 7.6% at screen
metering
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.
Normal
Half-press
Release position
Full-press
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 halfpress 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.
28
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.
In focus
Turn focus ring clockwise
Turn focus ring counter clockwise
-- 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
30
3.7 Using Focus Lock and Infrared Focusing
Use the focus lock when your intended focus point is not within the
focus frame. In such cases where a subject is not located in the center
of a frame, use the focus lock function to lock the focus before releasing
the shutter.
1. Set the focus mode selector lever to S or C.
Put the subject in the focus frame and half press the shutter release
button.
2. Lock the Focus.
When the focus mark • in the viewfinder LCD is lit, press the AF lock
button on the front of the camera to lock the focus.
3. Adjust the Composition.
With the shutter release button half-pressed, slide the camera to
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.

3.10Flash 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.
A
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.
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.
38
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.

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 .

For more info on Metz, contact the local Metz dealer or www.metz.de
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.

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

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.
44
4.1 Quick Start (shooting untethered)
1. Connect a Leaf Credo digital back to the camera and install the
focusing screen if applicable.
2. Charge the battery (see page 12), then insert it into the back and
either a Li-Ion rechargeable battery pack or AA batteries into the
camera.
3. Insert a CompactFlash card into the Leaf Credo back.
4. Switch on the power to the back and camera and select a drive
mode.
5. Choose an exposure mode.
6. Select a focus mode on the camera body and lens if applicable.
7. Set the date and time (see page 21).
8. Set the ISO and White Balance (see page 24).
9. After shooting, transfer images into Capture One software from the
CF card using a card reader.
10.Edit images in Capture One and output as required.
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+/AF/AFDIII, Phase One 645DF+, Hasselblad
555 ELD (DIG mode), Hasselblad H or Contax 645. The electronic
communication with the body ensures that the Leaf Credo back is ready
before allowing release of the next shot. However, users of other camera
bodies that do not use the electronic interface from the Credo have to
wait for the ready beep signal before releasing the next shot.
46
4.3 Indicator Light
Credo series digital backs feature an indicator LED located beside the
on/off button. When the Leaf Credo back is in sleep mode, the green
LED is illuminated. The LED goes out as soon as the back is activated.
In general, if the LED is not illuminated and the back and camera are on,
the camera is ready.
4.4 CF Card LED
There is an additional red LED indicator located next to the CF card slot
(under the cover). It indicates CF card activity. Do not remove a CF card
from the card slot when this red LED is on. Removing a CF card while
the red LED is on can damage the formatting of the card, and images or
data might be lost or corrupted.
47
4.5 Tethered and Untethered Operations
Untethered: A Leaf Credo series back can be operated as a fully
portable battery powered unit. Image files are shot and transferred to a
CompactFlash card which is inserted in the CF card slot on the left side
of the camera back.
Tethered: Remember to always keep a battery in the Leaf Credo back
even when shooting tethered to a computer via a FireWire connection.
When operating tethered, image files can be shot to a CompactFlash
card or transferred directly to the assigned capture folder in the Capture
One application on the computer hard disk. (See page 80 for more
details about charging the battery when tethered to a computer).
Driver Set-up
Find out more on installation and activation of software on page 8 and
10 of this User Guide. There is no specific program set-up. Check
the Capture One User Guide for recommended hardware. Firmware
announcements are available on our website, and in our newsletters.
Connecting
The maximum length of a compatible FireWire cable is 4.5 meters.
Longer cables might require a third party power solution or a FireWire
hub. Leaf Credo series backs match the FireWire 800 standard.
Plug the FireWire 800 cable into the Credo unit and into the back of
your Mac or Windows PC. (It is not recommended to use a FireWire
port on the front of a computer as it can be less stable). Capture One
automatically recognizes the Leaf Credo back and settings. Read more
on shooting tethered in the Capture One software manual.
Note: Leaf Credo backs are compatible with FireWire 400. Order a
Mamiya Leaf FireWire 800 to 400 cable 4.5 m. Part no: 50300164.
48
Tethered Operations Continued
The display on a Leaf Credo series back can be either be turned off while
shooting tethered or set to display the images while they are shot, just as
if shooting untethered. It is also possible to enlarge a section of an image
on the Credo screen to help check focus of the current and upcoming
captures.
A Leaf Credo back defaults to its untethered mode when the FireWire
800 or USB 3.0 cable is removed in its Auto Storage setting. Captured
image files are stored on a CompactFlash card, and the unit’s battery
provides power.
The Leaf Credo back can be forced to shoot to either CompactFlash, or
via a USB 3.0 or FireWire 800 cable to a computer. Find out more on the
Storage Mode on page 81.
Online Support
For more information on shooting tethered with Capture One, consult the
online user guide available in the Capture One Help menu.
49
4.6 CompactFlash Card Usage
It is important to follow a few simple guidelines to help avoid loss
of data when working with CompactFlash cards, card readers and
digital cameras. Mamiya Leaf recommends that you test-drive all new
CompactFlash cards with your Leaf Credo back. By performing an
initial test to verify that the capture files are stored properly on the card
and can be accessed on a computer you avoid unpleasant surprises
on location or when you return from a job. CompactFlash cards are
manufactured by other suppliers and Mamiya Leaf cannot guarantee that
the cards are not defective.
Inserting and Ejecting on the Leaf Credo Back
The CompactFlash card is inserted in the slot located under the cover on
the left-hand side of the Leaf Credo back.
Insert the CompactFlash card with the brand label facing the display end
of the digital back as shown in the image.
The cover can be closed when the CompactFlash card is fully inserted.
To eject the card push the small button above the card once, and an
ejecting pin comes out. Pushing this pin all the way back in ejects the
card.
Microdrives are not recommended for use with Leaf Credo backs.
50
4.7 Secure Storage System (3S)
You can always be sure that your data is safe when working with
memory cards in a Leaf Credo back. The Mamiya Leaf Secure Storage
System (3S) provides the industry’s safest memory card handling. The
3S technology automatically checks your card’s file structure every time
it is inserted into the Leaf Credo back. If the Check Disk function finds
an error, it prevents usage of the card until it is corrected or the card is
formatted.
How does 3S work?
A complete disk check for a valid file structure is performed as soon as a
card is inserted into the Leaf Credo back.
Lower gigabyte capacity cards load quicker than high capacity versions.
It is not recommended to turn off the Check Disk function. If you want to
turn it off go to Home > Settings > Check Disk.
Disk Check Summary
3S technology is a safe storage system integrated into the Leaf Credo
back and is much more rugged than anything else seen in the industry.
DSLR cameras do not have this level of storage security.
Benefits include:
• No need to format a card on a computer.
• Damaged or incorrectly formatted cards are detected immediately.
Leaf Credo backs also have the ability to reformat and correct these
cards.
• Ejecting a card while it is writing a session does not necessarily
damage the file structure of the entire CompactFlash card. Only the
image being written and the images in the buffer can be damaged.
51
4.8 Formatting your Memory Card
Most CompactFlash cards are preformatted and ready for use in the
Leaf Credo backs. However, Mamiya Leaf recommends that all cards be
formatted in the Leaf Credo back to ensure their optimum performance.
Memory card formatting is done in either FAT 16 or FAT 32 depending on
card size. (Leaf Credo backs support CompactFlash cards formatted in
both FAT 16 and FAT 32.)
Using CompactFlash Cards in a Card Reader
A card is mounted as a removable drive on a computer after it has been
inserted into the card reader and connected to a Mac or PC. Windows
and Mac OS X have the required drivers for the CF card reader. For
information on how to import files to Capture One, consult the Capture
One online user guide available under Capture One Help in the Help
Menu.
Warning!
Ejecting a card or removing the battery while the Leaf Credo back is still
writing (when the red LED is on) causes images that are not written to
the card to be permanently lost or damaged. Do not bend or flex your
CompactFlash card. Keep the card away from moisture, grit and sand.
Use a CompactFlash card case as a storage container when not in use.
52
5.0 Navigating the Credo

7.2 Power Management
The Power Management menu option has three criteria to help preserve
battery life and help keep operating temperatures low when working in
hot conditions.
Display Off Time
Switch off the Credo’s display screen after 5 seconds, 20 seconds, 1
minute or 5 minutes. The display can also be set to remain permanently
on while the Credo is in operation with the Always On option.
Battery Charging
The Leaf Credo back has an integrated battery charger to ensure that
the battery is charged when shooting tethered via a USB or FireWire
connection. This function can be switched off or set to Slow or Fast. The
Slow and Off settings should be chosen to preserve the battery life of a
laptop when shooting tethered.
Note: The battery only charges via a USB or FireWire connection when
the Leaf Credo back is switched on. Only after it has been switched on,
does it continue to charge when it is turned off.
Auto Power Down
Auto Power Down determines the amount of time before the Leaf Credo
back shuts down, when there is no activity. Choose 1 minute, 5 minutes,
30 minutes, 2 hours or deactivate this function by selecting Off.
Press the Power button to switch on and restart the Leaf Credo back
after it has shut down.
79
7.3 Format Card
Select Format Card to erase all data on a memory card. Memory card
formatting is done in either FAT 16 or FAT 32 depending on card size.
(Leaf Credo backs support CompactFlash cards formatted in both FAT
16 and FAT 32).
7.4 Check Disk
A disk check is performed on every memory card that is inserted into
the Leaf Credo back. Mamiya Leaf recommends leaving this feature
turned on, to maximize data security on memory cards. This feature can
be deactivated in this menu. Read more about the Mamiya Leaf Secure
Storage System on page 52 of this User Guide.
7.5 Storage Mode
Storage Mode allows users to configure how a Leaf Credo back stores
image captures. Auto is the default storage setting and it detects and
automatically stores image files to a memory card if it has been inserted
in the Leaf Credo back.
If the Leaf Credo back is being used in tethered mode, it stores image
files directly to the computer via the connected FireWire 800 cable. The
FireWire has priority if a card is in the Leaf Credo back at the same time
as it is connected by FireWire to a computer.
Note: The Leaf Credo back can be forced to shoot to either
CompactFlash or via a FireWire 800 cable to a computer by selecting CF
or FireWire respectively. An Error Message appears on the Credo screen
if the Leaf Credo back is not tethered to a computer and the Credo card
slot is empty.
80
7.6 File Format
A Leaf Credo back can save files in two different Raw formats;
IIQ L and IIQ S. IIQ stands for Intelligent Image Quality Raw.
IIQ L is the default setting and it is a lossless capture format.
IIQ S is a smaller file that is not a totally lossless format.
An IIQ L file is approximately 1/3 the size of a processed TIFF.
An IIQ S file is approximately 1/5 the size of a processed TIFF.
7.7 Camera Mode
There are two primary choices in the Camera Mode menu. Mamiya
mount Leaf Credo backs have three choices. Select one of the following
options:
Normal: The recommended default setting.
RZ67ProIID: This mode is designed to optimize the Leaf Credo back’s
operating performance with the Mamiya RZ67 Pro IID camera body.
7.8 Shutter Latency
The Credo’s CCD is put to sleep to reduce power consumption when it is
not in use. The Credo needs to wake up before shooting and the timing
of this wake up signal is referred to as the Latency. The recommended
setting is Normal Latency if the Credo is used with the Mamiya 645DF+.
Only change to Zero Latency if you work on technical, large format
cameras or certain manual cameras in special situations.
7.9 Image Orientation
The Image Orientation function sets and stores the orientation of all
subsequently captured images. Select 0°, 80°, 180° or 270° to force the
back to mark images as captured with that orientation. The Auto setting
uses the back’s built in orientation sensor to determine the orientation
at the moment of capture. Changing this setting does not affect how
captured images are displayed on the LCD.
81
7.10Auto Preview Mode
The Auto Preview option can be switched On or Off. Select On to revert
to a Browse mode when shooting. Select Off to remain on the same
display.
7.11Display
The Display menu option has an option for Brightness, Display Off Time
and Ready Beep.
Brightness

conditions. The default setting is 80% but in bright outdoor illumination
this can be increased up to 100%. Users may choose to lower
the Brightness when working in low light environments, such as a
photographic studio.
Altering the Brightness setting only affects the brightness of the screen. It
does NOT affect the Exposure Warning, Histogram and the exposure of
captures.
Display Off Time
Switch off the Credo’s screen after 5 seconds, 20 seconds, 1 minute, 5
minutes. The display can also be set to remain permanently on while the
Credo is in operation with the Always On option.
82
7.12Ready Beep
The Leaf Credo back emits a small audio beep after every capture is
taken. This Ready Beep signals that a capture has been completed, and
that the Leaf Credo back is ready for the next shot.
The Ready Beep can be set to either None, Single or Multi. The default
setting is Single. Multi is ideal for use in noisy surroundings. None
deactivates the audio Ready Beep.

9.12Depth of Field
Depth of field (DOF) 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 DOF 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. Simply read the figures which
appear above the f/stop numbers on the distance scale of the lens.
Depth of Field Preview Button
When the preview button is pressed in, the depth of field for the aperture
set on the camera can be checked by looking through the viewfinder.
After focusing, press the preview button. The diaphragm is stopped
down to the set aperture.

9.13Infrared Photography
Infrared Photography is complicated when using digital backs, as the
digital back is adjusted to match the viewable light perfectly.
Use a dedicated digital back for infrared photography. The Leaf Credo back
needs to be adjusted to work properly for infrared photography. DO NOT
TRY THIS AT HOME!
– All corrections in this area must be done by Mamiya Leaf to ensure
precision. If you remove the protective glass or make other physical
adjustments on the back the warranty is immediately voided.
If you are considering Infrared Photography, contact your
local Mamiya Leaf dealer for technical advice and pricing.
Infrared light has a slightly different area of sharpness compared to
visible light, so when the distance is set on the lens, you should always
manually correct sharpness to be in front of the red dot.
Notice:
You cannot take photos in AE modes
when using an infrared back as the AE
is based on visible light.
99
Do not use your camera’s light meter when photographing infrared, as
the light meter is designed to measure visible light.

9.17Lenses and Multi-Mount
When it comes to lenses, Mamiya Leaf provides the widest range of
possibilities to ensure photographers get the most creative freedom from
their Mamiya camera.
This chapter looks at some possible lens systems. However, it is
worth noting that there are even more applicable lenses available than
presented in the upcoming pages. Users can find more information from
Mamiya Leaf dealers on items such as mount-adapters, for example the
Phase One Multi-Mount.
Note: Errors or damage caused by third party products are not covered
by the warranty. Use new products with caution.
9.18Function of the Phase One Lens Adapter
To mount the Phase One Multi-Mount on the Mamiya 645DF+, match
the white Lens Mount Alignment Mark on the Multi-Mount with the
Lens Mount Alignment Mark on the camera and turn slowly clockwise.
NEVER use force to mount the ring. When the Phase One Multi-Mount
is mounted, you can mount Carl Zeiss/Hasselblad V and Hasselblad 200
series lenses on the camera.
106
Notice:
Since the focusing screen’s surfaces are
soft and easily damaged, handle them
carefully.
Never touch the surface with bare
fingers. Should dust settle on it, merely
blow away by using a blower.
If the focusing screen needs cleaning,
send it to the nearest authorized Phase
One service center.
Do not attempt to clean the surface
of the focusing screen, as it is very
delicate.
Do not touch and damage the mirror in
any way.
10.0Maintenance
The Mamiya 645DF+ generally needs very little maintenance. But this is
a professional tool and should be treated with care and caution. Always
do test shots before a photographic session if the camera has not been
used for a long period of time.
A frequently used product should be inspected periodically at the nearest
official Mamiya Leaf repair center. Do NOT try to repair any camera, lens
or back errors or malfunctions – consult your local dealer.
10.1Changing the Focusing Screen
1. Remove the lens.
2. Pull the Focusing Screen Release lever A forward, as illustrated, with
tweezers to ease the focusing screen down.
3. Remove the focusing screen from the focusing screen frame
by grasping the tab on the edge of the screen with tweezers as
illustrated.
4. When installing the screen, pinch the tab of the screen with tweezers,
and place the screen on the screen frame.
5. Push the screen frame up using the tweezers until hearing a clicking
sound. The screen is now properly installed. Never press down on
other parts as this affects the focus function.

10.2Battery Socket
Notice:
Never leave batteries in the socket if the camera or back is not going to
be used for long periods of time.
Make sure to re-install the empty
battery case into the body.
The empty battery cassette must be
inserted into the body.
The batteries may generate heat if the
external battery case is connected to
the body while the batteries are loaded

10.5Lens Maintenance
Never touch the inner optics of the lens with your fingers. Keep the inner
optics perfectly clean with air, a lens brush or the dry cloth delivered with
the lens.
Do not touch the contacts. Keep the contacts clean with either a dry cloth
or by using a fiberglass brush. Do not use any other tools on the lens.
The lens is not waterproof. It should be immediately dried with a cloth
if it becomes wet. If it is exposed to salt, moisten a cloth, wring it and
carefully clean.
10.6Back Maintenance
Cleaning the IR Filter
The Leaf Credo back must have the protection plate fitted when it is
not attached to a camera. Dust may accumulate on the IR filter, which
degrades the image quality if not removed. Follow the directions found at
http://www.mamiyaleaf.com/cleaning.asp.
10.7IR Filter on the CCD
The IR filter (Infrared reduction filter) is permanently mounted on top of
the CCD. The filter may not be removed for several reasons:
• The focusing of the Leaf Credo back camera back can be altered.
• It is only possible to remount the filter without dust getting in between
the filter and the CCD if you have access to special clean room
facilities.
• The Mamiya Leaf Product Warranty is terminated.

13.0 Open Platform –
Freedom of Choice
Mamiya Leaf’s Open Platform policy delivers maximum choice and
compatibility with a wide range of different camera platforms.
This section covers the Leaf Credo back’s compatibility with the
Hasselblad V and H series, Mamiya RZ67 Pro IID, Phase One 645,
Mamiya 645, Contax 645 and View Camera solutions.
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+/DF/AF, Phase One 645DF+/DF/
AFDIII or Hasselblad 555 ELD (DIG mode). The electronic communication
with the body ensures that the Leaf Credo back is ready before allowing
release of the next shot. However, users of other camera bodies that do
not use the electronic interface from the Credo must wait for the ready
beep signal before releasing the next shot.
Viewfinder Masks
Cameras including the Mamiya RZ67 Pro IID and Hasselblad V-series
need a viewfinder mask as the image area of these models is different to
the image sensor size of the three Credo models.
116
13.1More Details: Leaf Credo and Mamiya 645 Series
Cameras
Power Management and Shutter Latency
The Credo CCD is put to sleep to reduce power consumption when it is
not in use. The Credo needs to wake up before shooting and the timing
of this wake up signal is referred to as the Shutter Latency.
The Leaf Credo and Mamiya 645DF+ camera body response
time is independent of the shutter latency setting so it is therefore
recommended to keep the latency on the Normal (default) setting, as this
ensures a longer battery life.
Studio Flash Sync on the Camera Body
A flash sync lead should be connected to the camera body when using
the Leaf Credo back on Mamiya 645DF+, DF, AF, Mamiya AFD or AFDII
models.
Always use a flash cable and/or equipment that provides grounding for
the flash.
Image Orientation
The CCD in the Leaf Credo back is positioned in a landscape orientation.
However, the Leaf Credo back has an internal sensor that detects when
it has been rotated. Thus, when the camera is rotated and an image is
captured in portrait position the image appears correctly oriented on the
LCD and in the Capture One application.

14.0 Leaf Credo back for
Mamiya RZ67 PRO IID
The Leaf Credo backs are compatible with the Mamiya RZ67 PRO IID
with the use of an adapter plate.
The Mamiya 645DF+ version of a Leaf Credo back can be used on a
Mamiya RZ67 PRO IID with a Mamiya RZ67 PRO IID adapter plate.
(Mamiya Leaf # 518-04228A)
14.1Mounting Leaf Credo back on the Mamiya RZ67 PRO IID
1. Place the bottom of the Leaf Credo back in the locking mechanism.
2. Press the button at the top of the back with your thumb and lever the
back into place.
3. Release the button to lock into position.
Note: It is important to ensure that the bottom part of the Leaf Credo
back is attached correctly before the upper locking mechanism is
pressed together.
Mounting the Leaf Credo back Vertically
The CCD in the Leaf Credo back is positioned in a landscape orientation.
However, it is possible to mount the Leaf Credo back in an upright
orientation to capture images in a portrait format without having to rotate
the camera. The Leaf Credo back has an internal sensor that detects
when it has been rotated so images appear correctly oriented on the
LCD and in the Capture One application.
Mount the Leaf Credo back in the portrait position by lining up the
adapter mount to the corresponding indentations on the left side of the
back. Press the button and lever the back into place. Release the button
to lock into position.
14.2Viewfinder Masking
118
The image area of the Mamiya RZ67 Pro IID at 56 x 69.5 mm is larger
than the size of the three Credo models’ sensors so it is necessary to
insert a viewfinder mask.
There are two different masks available for the Mamiya RZ67 Pro IID
according to the specific Credo that is being used. (The Credo 80 and
Credo 60 models’ CCD is 53.9 x 40.4 mm while the Credo 40’s CCD
measures 43.9 x 32.9 mm).
Installing a Viewfinder Screen
4. Remove the viewfinder from the camera body according to the
manufacturer’s instructions.
5. Remove the focusing screen, and then replace it with the supplied
focusing screen.
6. Reinstall the viewfinder on the camera body according to the
manufacturer’s instructions.

dismount the viewfinder and remove the focus screen.
119
14.3More Details: Mamiya RZ67 Pro IID
Mode Selector
The mode selector on the trigger button should be turned to the white
dot when used with the Leaf Credo back. The selector should be set to
the orange dot to avoid draining the small battery when the Leaf Credo
back is attached to the body and not in use.
Warning: Even if the Leaf Credo back is turned off, the battery drains
slowly if the orange dot is not selected.
Shutter Latency Setting Mamiya RZ67 PRO IID
Select the special Mamiya RZ67 PRO IID camera mode, which is
available in the Camera mode menu to ensure that the correct latency
setting is used.
Studio Flash Sync on the RZ lens
A flash sync lead should be connected to the port on a lens when a Leaf
Credo back is used on a Mamiya RZ67 PRO IID. On the older PRO II,
use the flash sync connector on the Adapter plate. (The flash sync port
on the Leaf Credo back is for use with large format cameras where no
digital interface is available).
Mirror Up
Mirror up operation is only recommended if using Mamiya’s own double
cable release.
Double Exposure
It is only possible to get a double exposure when a Hasselblad V mount
plate is being used. Avoid a double exposure by waiting for a ready-beep
from the Leaf Credo back before capturing another image.
120

129
16.3More Details: Hasselblad H Series
Camera Display
The Hasselblad H1/H2 incorporates a screen that displays information
about the camera set-up. It shows the aperture value, AF mode, shutter
speed etc.
The Hasselblad H1/H2 also displays some Leaf Credo back information
on this screen. For example, error messages including Digital back
storage media is full are displayed on the screen if the CompactFlash
card being used by the Credo back is full to capacity.
ISO Settings
The ISO value is also displayed on the H1/H2 camera screen. The
ISO setting can be adjusted from the camera back or in Capture One
software when shooting tethered.
Consult page 24 of this manual for details on setting the ISO. Go to page
49 for more information about tethered shooting.

130
Viewfinder Information
The viewfinder information bar is located below the image area within the
viewfinder display. It displays the camera’s exposure mode and values
etc. It also includes a counter with the number of captures remaining
on the storage media (see top bar circled left). ‘99’ is the maximum
number displayed. ‘99’ continues to be displayed if there are more
than that remaining on a CompactFlash card. An ‘E’ indicates that the
storage media is full. Users must delete some captures or replace the
CompactFlash card before continuing (see bottom bar circled left).
Double Exposure Protection
It is not possible to accidently double expose an image by capturing
one image quickly after another when a Leaf Credo back is used on a
Hasselblad H1/H2.
Note: At the end of an exposure, image information has to be moved
from the CCD to the processing system. During this short period of time
the CCD must be protected from light exposure. The Leaf Credo back
ensures that the CCD is safely cleared of information by disabling the
Hasselblad camera’s shutter release during this procedure.
Image Orientation
The CCD in the Leaf Credo back is positioned in a landscape orientation.
However, the Leaf Credo back has an internal sensor that detects when
it has been rotated. Thus, when the camera is rotated and an image is
captured in portrait position the image appears correctly oriented on the
LCD and in the Capture One application.

134
17.3More Details: Contax 645
Exposure Modes
The Contax 645 manual (M) and semi-auto exposure modes (Av, Tv)
are fully supported by the Leaf Credo back. Please note that Bulb is
only supported on Contax/Leaf Credo back when used in conjunction
with the Live View function. Go to Chapter 19 (from page 142) for more
information about Live View.
Check the relevant Contax 645 manual for more information on exposure
modes.
Ensure that exposure times are limited between 1/4000 second and
approximately one second to obtain the highest possible quality with a
Leaf Credo back and Contax 645. Please note that it is not possible to
expose images longer than two minutes with a Leaf Credo 80 and 60
seconds with a Leaf Credo 60 or 40.
ISO Settings
The Contax 645 exposure modes use the ISO value set in the Leaf
Credo back. The ISO setting can be adjusted from the camera back or in
Capture One software when shooting tethered.
Consult page 24 of this manual for details on setting the ISO. Go to page
49 for more information about tethered shooting.
Double Exposure Protection
It is not possible to accidently double expose an image by capturing one
image quickly after another when a Leaf Credo back is used on a Contax
645 e.g. when using the continuous drive mode.
135
TTL flash
Using TTL flash with the Contax 645 camera and Leaf Credo back
results in a two f-stop overexposure. When using TTL flash, the exposure
compensation on the flash unit must be set to –2 f-stops.
This overexposure happens because the CCD element reflects light
differently than film and this cannot be communicated to the Contax.
Image Orientation
The CCD in the Leaf Credo back is positioned in a landscape orientation.
However, the Leaf Credo back has an internal sensor that detects when
it has been rotated. Thus, when the camera is rotated and an image is
captured in portrait position the image appears correctly oriented on the
LCD and in the Capture One application.
17.4Flash Lead Connection
A flash cable is always connected to the Contax 645 camera body.
The flash sync cable must not be connected to the camera back when

View Cameras
The Leaf Credo back is compatible with most technical view cameras
and large format cameras via camera interface adapters. The Leaf Credo
back supports most mechanical shutters and some electronic shutters
from Horseman, Schneider and other manufacturers.
Sleeping Architecture
The Sleeping Architecture was developed to help produce noise free
exposures without the use of active cooling of the CCD. The sleeping
architecture ensures minimum heat build up inside the back by putting
all the unused circuits to sleep, and only powering the circuits that are
actually needed at any given time.

18.1Using the 2-shot Release
The Leaf Credo back can be used with mechanical shutters that can be
fired twice within four seconds. The first release of the shutter activates
the digital back; the second release is for the exposure. If the time limit of
four seconds is exceeded, the camera gives a warning ‘beep’ followed
by a 2-shot error warning that is displayed on the LCD screen.
There are several automatic or semi-automatic 2-shot solutions available
from third party manufacturers for use with a mechanical shutter. Please
ask your dealer for more information.
18.2Using the 1-shot Release
The 1-shot release cable is created to simplify your studio workflow.
1. Connect the flash exit (circled left) to the shutter and plug the opposite
end to the multi-pin port on the Leaf Credo back (via Part# 50300144
from multi-connector to mini jack female).
2. Connect a flash sync lead to the port on the Leaf Credo back.
3. Close the shutter if necessary.
4. Push the button (circled left) on the 1-shot release lead to ‘wake up’
the camera back and take the shot within a few seconds.
Note: It is not possible to control the exposure or trigger the shutter from
Capture One when using a fully manual camera. Only limited EXIF data
is recorded when shooting with manual cameras. The Leaf Credo back
adds a calculated approximate shutter speed but the aperture value is
not recorded.

18.3Shutter Latency Settings for Technical Camera
Adapters
Technical camera adapters for the Leaf Credo back can be used with
both normal and zero shutter latency.
Select the Normal latency setting if the Leaf Credo back is used on a
camera with a 2-shot release.
Please note: The Zero shutter latency setting increases the power
consumption of the Leaf Credo back, as it is always prepared for
exposure.

19.0 Live View
The Live View function is intended for use when a camera is mounted on
a tripod and the subject is stationary.
Live View is ideal for use with technical view cameras in a studio
environment or for architectural photography, where you would ordinarily
have to rely on an external viewfinder or a separate focusing glass/sliding
adapter.
The Live View function enables you to compose an image directly on the
high resolution display of the Credo digital back. Focus can be checked
by zooming into a subject on the screen by up to 400%.

19.2White Balance
1. After selecting the White Balance Picker, tap the screen to select a
neutral area to calibrate the Live View.
2. If a precise white point is difficult to achieve in full screen view, slide a
finger on the right side of the screen to zoom into a part of the image
that you want to use as white reference.
Exit the White Balance mode by deselecting the picker in the Dynamic
menu. Alternatively, the Home soft button on the Leaf Credo back to
return to the Home screen.
Go to page 63 to find out more about the zoom function.
19.3Quality and Brightness
1. Go to the Dynamic menu and select the Live View exposure controls
icon (circled left).
2. Two sliders appear at the bottom of the screen in order to help you
adjust Live View to suit the ambient lighting conditions being used. The
top slider is a speed vs. quality slider. Increase the quality by moving
slide to the right or achieve a faster frame rate by moving the slider to
the left. The lower slider controls the brightness of the Live View.
143
19.4Zoom
Zoom into the Live View by sliding a finger up in the left side of the
screen. Double tap on the image to bring up a 100% view. If a zoom is
already applied, double tap the screen to return to a full image view.
19.5Grid

19.6Auto Stop and Start
Live View is paused if the screen is not touched for one minute.
Touch the screen again to restart Live View.
144
19.7Accessories
Live View is easily overexposed due to the high sensitivity of the Credo
CCD sensor and its large size. It is sometimes necessary to take steps to
prevent overexposure by either stopping down the aperture or by using
a neutral density filter (ND filter). ND filters are widely available, and it is
even possible to get variable ND filters, that can prove invaluable when
working in changeable outdoor ambient light.
