SONY RX100 III & RX100 IV DIGITAL CAMERAS
By definition, the RX100 III and RX100 IV are the
best compact cameras Sony has ever made. Some
even rate these cameras as the best compact
cameras in the market (Kenrockwell.com). They
deliver absolutely stunning image quality and yet,
they’re compact enough to take anywhere.
Images maintain soft background defocus even when
zoomed in with the improved f1.8-2.8 24-70mm
Zeiss® lens. The ultra-fast BIONZ X processor adds
speed and accuracy for stills as well as beautiful full HD
videos (RX100 III) or 4K ultra-HD videos (RX100 IV). The
back illuminated technology of the 20.1 MP 1-inch Exmor
R® sensor doubles light sensitivity and reduces noise
levels –a great help when photographing in dimly
environments, such as in deep water. Markedly reduced
noise is evident when high-sensitivity settings are used for
capturing images in dark environments, such as during
night dives.
The built-in Zeiss® Vario-Sonnar T 2.9x zoom lens covers wide-angle to portrait-length perspectives to suit
working in a wide variety of environments. An f/1.8-2.8 maximum aperture benefits working in low
lighting and controlling focus throughout the zoom range. A built-in three-stop ND filter is incorporated
into the camera's design to suit shooting in bright conditions with wider apertures and for greater control
over how movement is depicted. The lens also features a Zeiss T anti-reflective coating, which helps to
reduce surface reflections, lens flare, and ghosting in order to produce imagery that is rich in contrast and
clarity.
Using the RX100 III, full HD 1920 x 1080 movies can be recorded in the high-quality XAVC S format. The
RX100 IV allows for 4K (UHD) video recording with full sensor readout and bit rates up to 100Mbps and
slow motion video recording up to 1000 fps. Full-pixel readout helps to minimize any artifacts in
recordings due to the ability to utilize data from the entire image sensor, which ultimately results in
smooth, high-resolution recordings.
Built-in Wi-Fi connectivity enables instant transferring of imagery to mobile devices for direct sharing
online to social networking, via email, and to cloud storage sites.

SETTING UP THE HOUSING
PREPARING THE CAMERA
1. Install a (preferably empty) memory card (16 GB+ capacity recommended) and a fully charged
battery inside the camera. Note that SDXC Class10 or UHS-I compatible memory cards are
required for high frame rate recording with the RX100 IV.
2. Remove the camera strap from the camera if one was installed.
3. Turn the Mode Dial so the Auto (green symbol) shooting mode is selected and aligned with the
white mark on the left of the wheel. This will allow for the camera and housing mode dials to be
aligned, so the housing mode dial will indicate the proper mode selected by the camera dial.
4. It is recommended to program the camera to the most frequently used underwater photo mode,
lighting and other key settings prior to installing the camera in the housing.
PREPARING THE HOUSING
1. When using the housing for the first time-
a. Peel the transparent plastic screen protector off the back door exterior of the housing.
b. Install the hand lanyard on the housing by inserting it through the lanyard loop on the
bottom right of the housing (facing from back), then pulling it through itself and testing it
in order to make sure it is secure (image #1 on the following page).
c. Install the housing side of the diffuser quick release secure line by tying it around the
upper rectangular loop at the top left side of the housing, where the Fiber Optic Cable
Plate secure string is attached to as well (image #2 on the following page). Please note
that this line may come assembled and then there is no need for installation.
d. Open the housing (see section “Opening the Housing” on the following page) and remove
the anti-glare hood out of the housing. Secure the anti-glare hood to the housing by tying
its secure string around the lower rectangular loop at the bottom left side of the housing.
Note
It is important that a first dive is always carried out with the housing
empty (no camera installed inside) in order to verify that the housing
watertight seal has not been affected during transport and after long
periods of storage.

FRX100 IV Housing Instruction Manual 20150809
14
Install the anti-glare hood over the anti-glare hood rails at the back of the housing. First
install the anti-glare hood over the top rail (image #3) and then gently and carefully
stretch it downwards to install it on the bottom rail, making sure it’s sitting securely on
both upper and lower rails (image #4).
e. If using a Hand Strap, install it on the two loops found at the right side of the housing.
Please refer to the section “Hand Strap” on page 23 for further information.
f. It is important that a first dive with the housing is always made without the camera in
order to verify that the housing watertight seal has not been affected during transport
and after long periods of storage.

OPENING THE HOUSING
1. Pull the small red tab located at the bottom of the latch dial outwards (up and away from the
housing), as indicated by the arrow direction (image #5). There is no need to apply any force.
2. While holding the lock dial up, turn the latch dial counterclockwise until the red latch tab is
located at the top of the latch and cannot be turned any further (image #6). There is no need to
apply any force.
3. Carefully open the back side of the housing.
4. Note that when opening the housing for the first time or when opening it after airplane trips,
increased resistance might be encountered. Therefore, it is important not to lock the housing
and to leave it slightly open when transporting by air.
CHECKING THE O-RING
1. Prior to each closure of the housing, the back door black O-ring should be visually inspected.
If there is any debris present, including dirt, sand, dust, hair or any other matter, it must be
cleaned to ensure a proper watertight seal.
2. In order to clean the black O-ring, first remove it from the housing:
a. Insert the O-ring remover between the black O-ring and the groove it is
seated in (image #7 on the following page).
Image #5
Image #6

FRX100 IV Housing Instruction Manual 20150809
16
b. Slip the tip of the inserted O-ring remover below the black O-ring, while making sure
the O-ring doesn’t get damaged (image #8 on the following page).
c. Carefully hold the O-ring with your fingertips in order to remove it from the groove.
3. Cleaning the O-ring is a simple matter of wiping it with a damp, soft cloth to remove the
foreign matter. Be careful the cloth you use does not leave any of its own material behind
as this can also affect the effectiveness of the seal.
4. Apply a slight layer of silicone grease on the black O-ring. Please note that the amount of
lubrication required on the O-ring is only enough to allow it to slip into place without friction,
so it does not twist or become dislodged. More grease is not necessarily better, and in some
cases might interfere with the watertight seal of the housing.
5. When replacing the O-ring, place it back into the groove starting at one corner and gently
pressing it into the groove all around the housing until it is all seated in the groove and no
part of it is sticking up or out of the groove.
6. The white O-ring featured on the back side of the front door should be visually inspected
prior to each dive. If there is any debris present, gently wipe the area with a soft microfiber
cloth in order to cleanse it.
7. The white O-ring featured on the back side of the front door shouldn’t be removed unless
it’s damaged.

WHEN INSTALLING THE RX100 III CAMERA INSIDE THE HOUSING
If using the housing to accommodate the RX100 III camera a small plastic C-shaped washer (included)
should be installed on the Select / Rotary Wheel control of the housing prior to installing the camera
inside. This C-shaped washer enables an easier and smoother use of this control with the RX100 III
camera. The C-shaped washer should only be installed once following this procedure:
1. Open the back side of the housing.
2. Identify the Select / Rotary Wheel control on the
interior back side of the housing.
3. Gently remove the black rubber disc installed at the
end of this control by pinching it and then gently
pulling it out using your fingers. Pull it away from its
black plastic 2-pointed seat (image #9).
4. Remove the plastic C-shaped washer out of its bag
and use small needle nose pliers to securely hold it
without damaging it (image #10).
5. Using one hand, press the Select / Rotary Wheel
control from the exterior side of the housing, so the
metal shaft sticks out from the inside.
6. Using your second hand, install the plastic C-shaped
washer on the control shaft. First, using small needle nose pliers, hold the C-shaped washer
against the shaft so it’s positioned between the housing backdoor and the black plastic 2 pointed
seat installed at the end of the shaft. Then push the C-shaped washer against the shaft until it
snaps securely into place (image #11).

7. Finally, re-install the black rubber disc at the end of the control by pushing it against the shaft
until it is fully and securely seated. Do so by mounting the 2 holes on the disc center onto the 2
protruding points at the end of the black plastic 2-pointed seat.
8. Once complete, install the camera inside the housing and test to control. If properly installed,
the control should work smoothly when turned or pushed against the camera button.
9. The C-shaped washer should remain in this position as long as the housing is used to
accommodate the RX100 III camera. In case of using the housing to accommodate the RX100 IV
camera, the C-shaped washer should be removed.
Important Notice: This procedure should only be followed if using the housing to accommodate the
RX100 III camera. Installing the C-shaped washer when using the housing with the RX100 IV camera
will interfere with housing functionality and potentially damage the camera and/or housing!
INSTALLING THE CAMERA
Since the FRX100 IV Housing is specifically designed for the Sony RX100 III & RX100 IV digital cameras,
installing the camera in the housing is quite simple.
1. Make sure the camera is turned off.
2. Hold the camera parallel to the housing and then gently install it inside (image #12). Avoid
inserting one side of the camera prior to the other, as this will make the installation difficult and
might cause damage to the camera or housing.
3. Take special care not to touch or damage the moisture detector device when installing the
camera. The Device is located inside the housing on the inner (right) side of the housing
interior to the latch dial (image #13 on the following page).
Image #12

FRX100 IV Housing Instruction Manual 20150809

4. If inserting a silica gel pack inside the housing in order to prevent moisture, it is best to insert it
on the left side of the camera, in the slot midway up between the two rubber shock absorber
mounts, where it doesn’t interfere with proper housing operation. It is important to make sure
that the silica gel pack doesn’t stick out, or else it might interfere with the watertight seal of the
housing.
CLOSING THE HOUSING
1. Turn the housing Control Dial till the Auto
shooting mode symbol is positioned at the
left (image #14). Make sure not to accidently
turn this control any further before closing
the housing.
2. Turn the latch dial so that the small red tab
located on the latch is pointed towards the front side of the housing (image #15 on the following
page).
3. Carefully close the back door of the housing, pushing it against the front door, while making sure
there is nothing sticking out of the housing or impairing the smooth closure of the back door.
Then firmly press the back door against the forward section of the housing.
4. Turn the secure dial clockwise till the lock dial clicks. The small red tab should then be pointed
towards the bottom of the housing (image #16 on the following page).

5. Gently try pulling the back door away from the front door. If the housing is properly closed, it should
be impossible to open the back door.
6. Visually inspect the black O-ring through the transparent back door for proper closure. Make
sure it isn’t twisted or out of the groove and that no foreign matter has been caught in the seal,
such as secure lines, sand, grit, hairs or any other foreign substance.
7. Turn the camera on and check that the extended
camera lens does not catch or bend the black
rubber seat on the inside of the lens port. It is
vital that this rubber seat does not disturb the
lens (image #17).
8. Test housing control buttons to make sure that
the camera was properly installed inside the
housing and that nothing interferes with normal
operation of the camera. It is recommended to
take a few images once the camera has been
installed inside the housing and prior to the dive
in order to ensure proper operation.
9. If making use of the internal camera flash, install the removable
flash diffuser on the housing and attach the flash diffuser quick release secure string in order to
avoid losing it underwater. Please refer to the section “Using the Built-in Camera Flash” for
further information.
10.Prior to diving with the housing, submerge it in a shallow tub of water or rinse tank. Carefully look at
the housing to make sure no bubbles are escaping from it and that no water is entering.
