Assembling the XF
IQ4 Camera System
Digital Back and Camera Body Modularity
Depending on how you purchased the system, the XF Camera System may
be supplied ready for use with the IQ4 Digital Back already attached, and
consequently, there is no need to remove it prior to capture. If, however, you
would like to do so, for example, to use it with a technical camera, please
follow the instructions below.
Removing the IQ4 from the XF Camera Body
1. Turn the Camera System oand remove any interface cables from the
Digital Back.
2. Push the IQ4 lock slider toward the XF Camera Body while
simultaneously pressing the IQ4 release button. Note that the lock slider
acts as a safety catch.
3. Tilt the IQ4 slightly backward from the top and gently lift the IQ4 othe
XF Camera’s guide rail.
Attaching the IQ4 to the XF Camera Body
1. Gently place the mounting plate of the IQ4 onto the bottom guide rail
of the XF Camera Body.
2. Push the back lock slider and press the release button simultaneously
to retract the back’s upper locking mechanism, and then push the IQ4
firmly onto the camera’s twin catches, using the bottom guide rail as a
pivot.
NOTE:
After removing the IQ4 from the XF
Camera Body, remember to protect
the sensor by reattaching cover, and to
attach the back port cover on the XF to
protect the camera from dust.
8Assembling the XF IQ4 Camera SystemXF IQ4 Camera System Manual |

Removing the lens
1. Press the lens release button on the right-hand side front of the camera
and keep pressed.
2. Rotate the lens counter-clockwise on the body until it stops, and lift it out
carefully from the body.
Attaching a lens
1. Looking down from the top of the camera, or from right hand side, align
the blue or the red index point on the lens with the blue or red index
points located on bayonet mount of the XF Camera Body and rotate
clockwise on the body until it stops and clicks into position.
Two dierent colored index points are available to allow easier attachment of
the lens to the camera. Either when looking downwards from above the camera
(blue), or in front of the camera looking from the side (red).
If you are not replacing with another lens, then reattach the front and rear
caps, and keep them always attached to the body to protect the mirror-
mechanism or lens elements from accidental damage.
Interchangeable Viewfinders
In addition to the Prism Viewfinder, the XF features an optional Waist Level
Finder (Part # 73090).
Removing the Viewfinder
1. Ensure the power of the XF Camera System is O.
2. Grasp the viewfinder securely with your right-hand and push the
viewfinder release slider forwards, towards the lens with the right thumb.
3. Lift the viewfinder up and out carefully, beginning with the rear of the
viewfinder then moving up and away from the camera body.
Attaching the Viewfinder
1. Ensure the power of the XF Camera System is O.
2. Hold the viewfinder securely with your right hand, with the viewfinder
tilting downwards slightly.
3. Place the front edge of the viewfinder so that it is resting on the front
edge of the body.
4. Ensure that the viewfinder’s front locating pins are aligned with the body’s
pin registration recesses, located in the front of the XF Viewfinder port.
(Both the electrical contacts and prism of the viewfinder must be aligned
with the body’s contacts and viewfinder screen recess.)
5. Carefully lower the rear of the viewfinder until level with the body, then
press the viewfinder down firmly until it clicks into place.
NOTE:
Ensure the viewfinder is securely attached before turning the power on and using the
camera. Failure to ensure the viewfinder and body are properly secured could result in a
camera malfunction. There is also a risk of dropping either the camera or the viewfinder
if the viewfinder is not securely attached! Always remember to protect the optical
elements.
XF Waist Level Finder Diopters
You can replace the default magnifier lens of the XF Waist Level Finder with
an optional Diopter and use the finder without eyeglasses in case you are
nearsighted or farsighted. Each Waist Level Finder Diopter has a fixed
correction value, for example minus two (-2), whereas the default magnifier is
neutral (zero correction).
The Diopters are accessories and can be ordered by using these part numbers:
• 73094 XF Waist Level Finder Diopter +2
• 73095 XF Waist Level Finder Diopter +1
• 73096 XF Waist Level Finder Diopter 0 (Included with the WLF)
• 73097 XF Waist Level Finder Diopter -1

camera system
Charging the batteries
When working untethered, the standard power source of both the XF Camera
Body and IQ4 back is the 7.2 V (3400 mAh) BP-911/914/915 type rechargeable
Li-ion battery.
To maximize battery performance, charge both batteries before use with the
supplied Pro Cube 2 charger. Approximately 2.5 to 3 hours are required to fully
charge exhausted batteries.
1. Connect the supplied power adapter to the charger and insert the
batteries into the charger slots. If charging only one battery, either slot
can be used.
2. The charge indicator will blink and display the battery’s approximate
capacity as a percentage.
3. Charging is complete when the charge indicator stops blinking and the
capacity level displays “100%”.
4. Remove the batteries and unplug the cable from the charger.
The Pro Cube 2 will display how much the batteries have been charged in mAh
since the charging session started. This can be useful if you are in a hurry and
know from experience that a particular amount of mAh is enough to get you
100 captures, for example. The three dots over a battery icon indicates on the
display which one is currently being measured.
Dual battery system
The XF Camera Body and the IQ4 use identical 7.2 V (3400 mAh) BP-911, 914,
915 type rechargeable Li-ion batteries and share the same charger for
convenience, however the IQ4 requires a battery to be loaded prior to use,
also when working tethered to a computer using a bus-powered interface
cable (Gigabit Ethernet or USB-C).
XF and IQ4 Power Sharing
The XF Camera Body and IQ4 are designed to share power from the two BP-
915 type batteries in the system, thereby providing improved operation time
for the full system. Make sure the feature is active on the IQ4 by setting
Power Management > Power Share With Camera ito On in the IQ4 Menu.
Charging a device by USB
The XF Pro Cube 2 can also be used to charge a device like a smartphone by
connecting it to the USB port on the charger. The display will show USB when
doing so. Note that the Pro Cube 2 will charge any inserted Li-ion batteries
fully before starting to charge the attached device over USB.

General advice for the battery and charger
Charge the batteries before use
Batteries discharge when not in use. For optimum performance, charge the
batteries before using the XF Camera and IQ4 .
Charge the batteries indoors
Only charge the batteries indoors (and away from moisture) at ambient
temperatures between 5–35 Celsius (41-95 Fahrenheit).
Remove batteries when not in use
Never leave the battery in the charger for an extensive period of time. When
charging is complete, remove the battery and unplug the charger from power
outlet. When the battery is left in the XF Camera Body or the IQ4 a small
amount of current is drawn, resulting in accelerated discharge and shorter
battery life. Remove the batteries when not in use.
Only use approved batteries
Use only 7.2 V BP-915 type batteries. Capacity in excess of 3300 mAh is
recommended. Some third party batteries may not fit into the XF Camera
Body or IQ4’s battery compartment, due to dierences in the manufacturing
tolerances. Do not try to force a battery into the compartment. When pressing
the battery release button it should slide out without being hindered. If a
battery can’t be removed, levering the battery out may cause damage. Please
contact your Phase One dealer for advice.
Dirt and fingerprints on battery terminals may cause loose connection and
corrosion. Clean the contacts with a soft-cloth before loading the batteries.
Shooting tethered
Always keep a battery in the IQ4 when shooting tethered to a computer via a
Gigabit Ethernet or USB-C connection. Please read the Power Connections
chapter for more information.
Use in foreign countries
The AC power adapter is supplied with several power plug adaptors for
international use. The power adaptor is compatible with 110 to 250 V AC
(50/60 Hz) power sources.
Only use the original power adapter or 12 V DC car adapter (supplied)
It is not recommended to use a portable voltage transformer with the battery
charger. Battery charging from a car’s 12 V electrical socket is possible but the
car battery will discharge if the engine is not running.
Powering On and Ofrom the XF Camera Body
Powering up both the XF and the IQ4 simultaneously is achieved with a short
press of the On/Obutton located on top rear of the grip on the the XF
Camera Body. A long press of the same button will power othe XF. The IQ4
will follow and power-oautomatically after a few seconds. The XF and IQ4
may also powered on and ofrom the IQ4, using the back’s power button.
NOTE:
In low temperatures, keep spare batteries
close to body temperature by storing
in an inside jacket pocket. Li-Ion type
batteries tend to lose eciency under
cold conditions.
NOTE:
There can be a low number of shutter actuations reported on a brand new XF Camera
Body or Leaf Shutter Lens. This is normal behavior as the shutter mechanism has been
tested during final quality check procedures. The shutter count on a new XF Camera
Body or Leaf Shutter Lens should never exceed 99.
For a Certified Pre-Owned Camera System that includes a physical shutter (Leaf Shutter
Lens, XF Camera Body) or recorded digital capture count (Digital Back), the actual
capture count should never exceed 5,000 actuations.

Setting Date, Time and Language
Setting the Date and Time on the IQ4
Date and time are set and controlled via the IQ4’s menu. When the IQ4 is
initially shipped from factory, or If the IQ4 has been without power for a long
period of time, it will automatically prompt you to set the time and date. Touch
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 IQ4. You can change this later in the Menu under IQ Settings > Date and
Time.
Setting Language on the IQ4
The XF IQ4 Camera System is delivered with the language set to English by
default. Follow the steps below to change the language of the IQ4 to one of
eight others available, including German, Russian, Korean, Japanese, Chinese
(simplified), Swedish, Italian and Spanish.
Swipe up from the bottom of the screen and tap on the IQ4 Menu icon.
Navigate to the Language menu item and select the preferred language option.
Each choice is displayed using the native language, with English noted in
parentheses.
Note: If you choose a language by mistake, and can no longer read the menu,
look for the menu item with (L) in it.
Security Code Protection
Access to the IQ4 can be protected by a four-digit security code that you will
have to enter on the touch screen after it has been turned on.
The security code protection is a safety measure to ensure that other people
cannot gain access to the IQ4 without your consent. This is of particularly
importance since IQ4 can provide wireless access over a network that other
people might have access to.
You can setup the security code as well as the level of protection by selecting
Menu > Security Settings on the IQ4. Please see the Security Settings chapter
later for full details.
Ready for Capture Beep
You can control whether you would like to get a sound beep from the camera
system whenever it is ready to capture the next image. It is on by default. This
is useful under a busy shot where you need to concentrate on your subject at
hand instead of checking to Capture Ready icon in the Status Bar on the
screen.
This is set by going to the IQ4 Menu and selecting IQ Settings > Ready Beep.
You have three options:
• None (O)
• Single (one beep)
• Multi (longer beep)

LED Lights
Removing the SD card
Installing XQD and SD cards
Using memory cards
The Phase One IQ4 supports both XQD and SD memory cards. Phase One
recommends that you use the supplied Sony XQD G Series 64 GB card or a
similar card with the same 400 MB/s write speed rating for optimal
performance.
If you plan on saving raw files to the SD card, use the supplied Sony SDXC
UHS-II G Series 64GB card. Otherwise, it is recommended to use SD card that
has a write speed of at least 100 MB/s and is marked with speed class U3.
Note: While the XQD card slot in the IQ4 is compatible with CFexpress cards
from a mechanical stand point, CFexpress cards are not supported yet. A
future firmware upgrade for IQ4 is planned to add support for CFexpress
cards.
Installing an XQD card
When inserting the XQD card into its media storage slot in the IQ4, make sure
that the labeling side on the card is facing towards the front of the back so
that the small triangles on the XQD card and the IQ4 XQD slot align. Slide it
straight into the slot until it clicks into place. If resistance is felt, stop
immediately, and check whether the card is oriented correctly.
Installing a SD card
Position the SD card so the label is facing towards the screen on the IQ4 and
slide it straight into the SD marked-slot until it clicks into place. You will need
to push the SD card into the port until it is recessed about 1 mm to ensure it
locks into place. You will hear a click once that point has been reached. If
resistance is felt, stop immediately, and check whether the card is oriented
correctly.
Removing an XQD card
Before removing the XQD card, confirm that the memory card access light is
o. Then press the card in with a finger to release it. The memory card pops
out and can be removed by using two fingertips.
Removing a SD card
Before removing the SD card, confirm that the memory card access light is o.
Then press the card in and let it go. The inserted SD card needs to be pushed
about 1 mm into the port before it will release. Use a small plate or a finger nail
to do so. The memory card will now be released, and you can remove it with
your fingertips.
Selecting cards for storage
You can choose to store the captured raw files on either the XQD or the SD
card. You also have the option to save a raw version to XQD and a jpeg version
to SD. It will be explained in a later chapter how to set this up.
LED Lights
The IQ4 feature two main LEDs located below the bottom left corner of the
screen.
A Blue LED will show when you power the IQ4 on. Two Red LEDs indicates
that the back is going through the boot up procedure.
When capturing an image the Green LED will blink rapidly to indicate that the
IQ4 is busy and that there are images in the buer that needs to be cleared to
the XQD card, the SD card and/or the local storage.
A Red LED indicates that the IQ4 is writing to the storage media, and
therefore the buer has not been emptied.

Navigating the XF
Camera System
Introduction to the Top Touch Screen,
Dials, Keys and XF Camera Menu
Top Touch Screen
Central to the operation of the Phase One XF Camera System is the XF Camera
Top Touch Screen. Sitting at the top of the large, ergonomic hand-grip this
touch-sensitive, multi-functional screen displays the camera’s essential settings,
keeping you fully informed at all times. Access to all of that information is quite
literally at your fingertips.
Not only does the Top Touch Screen allow you to make selections on the fly but
also falling naturally under the fingers and thumb of your right hand are all the
controls required to take command of the camera. To change the Exposure mode,
AF mode or Metering mode, or switch between manual ISO and Auto, just touch
what you want to adjust on the screen and select from the choices displayed.
Three dials and two keys
The XF Camera Body is designed with a dedicated, ergonomically placed dial
for each of the exposure settings; Shutter Speed, Aperture value and ISO.
The dials are highly customizable allowing, for instance, any one of them to
be reconfigured to alter exposure compensation in Av/Tv or Program, this
gives you direct control of the exposure mode.
The dials are modal, switching their function to navigate the Top Touch Screen’s
integral menu system, or to scroll through each of the displayed function settings
as a shortcut, depending on which mode is selected. A single press of one of
the two aluminum Top Keys is all that’s required.
The Front Key accesses the touch screen’s shortcut Camera Function mode,
while the Rear Key is used to reveal the integral Camera Menu.
Camera menu
In the menu system, the Front Dial is always used to scroll up and down through
the options, while either the Rear or Side Dial is used to navigate to the next
level and ultimately to select settings. That can’t be changed to avoid confusion,
but we’ve made the Top Front and Rear Keys modal and they’re customizable
as well. You can move up and down the menu with either set of controls or
reconfigure the keys to move between levels, but you’ll still need to make
selections using the Rear or Side Dial.
User configurable buttons
None of the buttons are labelled, as the features they access are customizable.
The Secondary Shutter Release Button, for example, located at the front of the
camera, and two the User Buttons, are easily reconfigured from the Top Touch
Screen’s Camera Control menu.
Once a function has been chosen, a simple half press of the shutter button is all
that is required to return the camera to full readiness, so you’ll never miss a shot.
The only time you will be asked to confirm the settings is when storing or
loading groups of settings in one of the three Custom modes, or when restoring
the camera to the default (factory) settings. No further confirmation of the
settings is necessary, meaning that you can rest assured, the settings are always
stored when leaving the menu system.

Top Touch Screen
XF Camera Body Controls
Shutter Release Button
The shutter release button has a two-stage operation: the first is accessed by
a gentle half press and activates both the exposure meter and auto-focus.
Pressing the button all the way down to the second stage trips the shutter,
either immediately in Single, Continuous Shooting or Exposure Bracketing
modes, or after initiating a certain action, such as focusing or locking the
mirror up for the Vibration Delay (self-timer) mode. If the camera is in Display
O(sleep) mode, a half press will wake up the camera and activate any
configured functions. Half press the shutter release can also be used to exit
menus and to return the camera to instant readiness.
Secondary shutter release button
This modal button is de-activated by default but when the shutter release
function is enabled (from the Top Touch Screen menu), the secondary shutter
release button replicates the functionality of the main shutter release button.
When enabled, the primary shutter release button remains active, and either
button can be used to release the shutter, or initiate a chosen action.
Top Touch Screen
As a multifunction panel the screen layout varies depending on the status of
the camera. However, the Classic layout is the main display, and it’s here that
the camera’s exposure values and mode settings are displayed. Shutter speed,
ISO and Aperture values are selected directly by the Front, Rear and Side Dials,
respectively. Other camera functions, depicted by icons, including capture,
metering and AF area modes may be selected quickly via the optional Camera
Function settings mode, after pressing the Front Key and scrolling through the
options using the Front Dial, or via touch. The Camera Menu display is used to
select the less commonly used camera functions. It is accessed via a short
press of the Rear Key, and navigated using the Front Dial. Options are chosen
using the Rear and Side Dials.
Note the brightness of the Top Touch Screen is determined automatically
using a sensor close to the screen, however the brightness setting can be
altered via the Rear Key > UI Setup > Backlight
NOTE:
If AF priority is set to “Focus”, the camera
will only capture an image if the AF system
obtains focus.

Front Dial
This is used to adjust the Shutter Speed by default, however it is modal, and
after pressing the Front or Rear Key it is repurposed for navigation of the
Camera Function settings and the Camera Menu, respectively. Note the Front
Dial is customizable.
Side Dial
This is set-up to adjust the Aperture value by default, and is similarly
repurposed for making selections from both the Camera Function settings and
Camera Menu via the Top Touch Screen. The Side Dial is customizable.
Rear Dial
This dial is principally used to adjust ISO, and like the modal Side Dial, is also
used for making selections from both the Camera Function settings and
Camera Menu. The Rear Dial is also customizable.
Top Front Key
A short press on the Front Key activates the camera function icons displayed
on the Top Touch Screen for quick selection, either by repeated pressing of the
key or scrolling with the Front Dial. Note the selection is highlighted in white.
Adjustment is made using either the Rear or Side Dial and the depicted
function is active immediately.
Top Rear Key
A short press and release of the Rear Key will gain access to the camera menu.
When the menu is displayed on the top touch screen, the Rear Key’s function
is repurposed for navigation and can then be used to scroll down through the
menu options (with the Top Front Key used to scroll back up). Note the Front
Dial can be used to scroll up and down the menu instead.
On/Obutton
A quick press will power up the camera. The XF start-up logo appears on the
Top Touch Screen, followed by the Classic display. If the power level is too low,
the battery warning light will flash continously in red. Otherwise if battery power
is sucient, the warning light stops and the mirror can be heard lowering into
position, ready for capture. This behavior is normal, as the mirror is automa-
tically locked up when powered ofor peace of mind during transportation. If
left untouched, the camera will enter the Display O(sleep) mode after 1
minute. Simply half press the Shutter release Button to reactivate the display
and ready the camera for capture. Note, the delay for the camera to enter the
Display O(sleep) or Mirror Position are all customizable via the Rear Key >
Power Management.
The On/Obutton is modal and a quick press while in the camera menu will
return it to the previous level, including exiting the menu altogether if pressed
when navigating the menu at its upper level.
To power the camera down, press and hold the button for 2 seconds. The mirror
can be heard being locked safely in position and the IQ back will power down
after 3 seconds.

Front User button
This button is by default set to activate the depth of field function. Note
continued pressure on the button is required to operate this particular function,
but the modal nature of this button means some functions accessed via this
button require only a single press and release, for example, when reconfigured
for AF-Lock and AE-Lock.
Rear User button
From the factory the Rear User button is programmed to activate the camera’s
AE-L (Auto Exposure Lock) function, locking meter readings made in Auto
and Manual exposure modes. The Rear User button is customizable,
External shutter release control (B.O.B)
The XF Camera System gives you the option to customize the functionality of
the Phase One Break Out Box accessory. This is done by pressing the rear user
key and selecting UI Setup > Control Setup > External.
By default it works like a shutter release button, but a particularly useful
feature is the ability to activate the two-step mirror control and shutter release
instead.
This will make the external button — the B.O.B release button — act with a two
shot mirror up function, raising the mirror on the first press, and shooting on
the next. You activate the feature by selecting UI Setup > Control Setup >
External > MUP-Exp.

Customizing
buttons and dials
You can customize the functionality of the buttons and dials on the XF
Camera to suit your preferred workflow. For example, you might want to
control auto focus separately from the shutter release button, or activate
Mirror Up or Live View with the push of a button. At the end of this section
you will be guided on how to setup some of the most useful customizations.
You can customize all of these buttons and dials on the XF Camera:
• Shutter Release Button (only for the half press action)
• Secondary Shutter Release Button
• Front Dial
• Side Dial
• Rear Dial
• Front User button
• Rear User button
• External Shutter Release (B.O.B.)
The OneTouch User Interface Flow Diagram section in this XF Manual will
show you exactly which functions or actions that can be assigned to each
button and dial. Follow the path Rear Key > UI Setup > Control Setup in the
diagram and note that the top option in a list is the default setting.
It is worth pointing out that the Front Dial, Side Dial and Rear Dial both have a
Primary and an Auto option. Most of the time, the XF Camera will use the
assigned Primary option, and the Auto option only comes into play when you
are using one of the automatic exposure modes; Aperture Priority (AV) or
Time Priority (TV). If you are using Aperture Priority (AV), for example, the
Side Dial will control the aperture value and you can then assign the Front Dial
to control the Exposure Compensation value. The Auto function can only be
set to either control the Exposure Compensation value or engage the Focus
Nudge feature.
Changing the function of a dial or button
Press the Rear Key and select UI Setup > Control Setup. Then select the
button or dial that you want to customize, and turn the Side Dial until you
have selected the desired functionality.
