Best Waterproof & Underwater Camera Housing for Fujifilm X100VI, X100V & X100 Series
Fujifilm X100 Underwater Housing & Waterproof Camera Case Compatibility Guide
Yes — Fujifilm X100-series cameras can be configured for use with the Outex waterproof camera housing system.
The Fujifilm X100 has become one of the most distinctive premium compact-camera families in photography. Its appeal comes from a combination that's increasingly rare: a relatively large APS-C sensor, a high-quality fixed FUJINON 23mm F2 lens, traditional tactile controls, a hybrid optical/electronic viewfinder and a compact body designed around the experience of making photographs.
The latest Fujifilm X100VI pushes that concept significantly further with a 40.2-megapixel X-Trans CMOS 5 HR sensor, 5-axis in-body image stabilization and sophisticated still/video capabilities — all while retaining the integrated 23mm F2 lens that gives the X100 its signature field of view.
Add the universal Outex waterproof camera housing system, and the X100 becomes something different again: a highly portable camera for underwater photography, swimming pools, snorkeling, boats, surf, travel, waterfalls, rain, snow, sand and creative over/under imagery.
And because Outex isn't molded around one specific camera body, the waterproof system can continue to be useful even if you eventually move from an X100-series camera to an interchangeable-lens Fujifilm — or another compatible camera system.

Why Take a Fujifilm X100 Underwater?
The X100 isn't an obvious underwater camera — and that is precisely what makes the combination interesting. Many underwater photographers start with one of two extremes: a small waterproof compact camera, or a much larger interchangeable-lens camera inside a camera-specific rigid housing.
The X100 occupies an appealing space in between. It gives you an APS-C sensor and a carefully matched prime lens in a remarkably compact photographic package. With the X100VI, Fujifilm pairs a 40.2 MP APS-C sensor with its integrated 23mm F2 lens, equivalent to approximately 35mm on a full-frame camera. The camera also adds 5-axis sensor-shift stabilization rated by Fujifilm at up to six stops. That combination makes the X100 especially interesting for:
- underwater portraits
- pool photography
- swimmers
- snorkeling
- travel and adventure
- boats and sailing
- kayaking and paddleboarding
- lifestyle photography around water
- environmental portraiture
- waterfalls and rivers
- documentary-style underwater photography
- split-level over/under images
- rain, sand and snow protection
A Camera You Actually Want to Carry
The greatest camera in the world isn't particularly useful if you leave it behind.
Portability is central to the X100 philosophy, and Outex complements that philosophy unusually well. Instead of surrounding the X100 with a large rigid camera-specific enclosure, the flexible Outex system conforms around the camera. For travelers, documentary photographers and creators trying to keep their equipment compact, the combination can preserve much of what makes the X100 appealing in the first place.

The X100VI's 23mm F2 Lens Is a Natural Environmental-Photography Focal Length
Unlike Fujifilm's X-T, X-H and X-S cameras, the X100 doesn't accept interchangeable XF lenses. Its 23mm F2 FUJINON lens is permanently integrated into the camera. On the APS-C sensor, that gives approximately the same angle of view as a 35mm lens on a full-frame camera. That moderate-wide perspective is one reason the X100 has become so popular for street, travel and documentary photography. It can also be useful around water. A roughly 35mm-equivalent perspective lets you work reasonably close to swimmers, people, boats and other subjects while still showing enough surrounding environment to tell a story.
For underwater portraiture, that can produce a very different look from the extreme fisheye imagery often associated with underwater photography.
Instead of emphasizing distortion and ultra-wide perspective, the X100 can lend itself to more natural, documentary-style images.
Think:
a swimmer beneath the surface with the pool environment visible
a family playing in shallow water
a surfer waiting between waves
a portrait made partially underwater
life aboard a sailboat
a traveler snorkeling near the surface
The camera's limitation — one fixed prime lens — can actually encourage a simpler way of working. You stop thinking about equipment and start moving the camera.
One X100 Camera, Three Useful Fields of View
The X100's fixed lens doesn't mean you're permanently limited to one perspective. Fujifilm offers two dedicated optical conversion lenses.
Standard X100 Lens: 35mm Equivalent
The built-in FUJINON 23mm F2 provides an approximately 35mm-equivalent field of view. This is arguably the most versatile choice for general underwater portrait, lifestyle and documentary work.
WCL-X100II Wide Conversion Lens: 28mm Equivalent
Attach Fujifilm's WCL-X100II and the camera's focal length is multiplied by approximately 0.8×, producing an approximately 28mm-equivalent field of view.
Fujifilm describes the converter as providing a broader perspective without a meaningful loss in image quality. The WCL-X100II is officially compatible with X100VI, X100V and several earlier X100 models.
For underwater work, this may be the most interesting X100 accessory. A wider perspective allows you to work closer to the subject while including more of the environment. That can be particularly useful for:
- swimmers
- underwater portraits
- snorkeling
- larger subjects
- environmental photography
- pools
- boats
- split-level images
The WCL-X100II uses a 49 mm filter diameter. Outex supports all industry-standard filter thread sizes, including the 49mm diameter. Step-up rings are also available for different sizes.
TCL-X100II Tele Conversion Lens: 50mm Equivalent
Fujifilm also offers the TCL-X100II, which multiplies the X100's focal length by approximately 1.4×, changing the field of view to approximately 50mm equivalent. Fujifilm specifically positions this converter for portraits and more natural perspective.
For underwater photography, the TCL would be more specialized than the WCL because longer focal lengths generally require greater camera-to-subject distance. But it can still be interesting for:
- close portraits
- shallow pool work
- detail photography
- above-water boating/lifestyle photography
- rain or environmental protection
The TCL-X100II uses a 67 mm filter diameter. You can use the same Outex cover and accessories for both port sizes.
Choosing the Correct Outex Port for Fujifilm X100
This is particularly important for the X100. Unlike an interchangeable-lens camera, you're not selecting an Outex port according to whichever removable lens happens to be mounted. You're configuring around either the built-in X100 lens or one of Fujifilm's conversion lenses.
Standard X100 Lens
Fujifilm specifies the X100-series filter diameter as 49 mm, using the AR-X100 adapter ring to attach standard 49 mm filters. Because the Outex front optical-glass port attaches like a filter, the relevant configuration begins with:
X100 → AR-X100 adapter → 49 mm connection → appropriate Outex front port
Confirm the exact camera/adapter combination with Outex when ordering.
WCL-X100II
Filter diameter: 49 mm
TCL-X100II
Filter diameter: 67 mm
So the practical reference becomes:
| X100 Optical Setup | Approx. Full-Frame Equivalent | Filter Diameter |
|---|---|---|
| Built-in 23mm F2 | 35mm | 49 mm with AR-X100 |
| WCL-X100II | 28mm | 49 mm |
| TCL-X100II | 50mm | 67 mm |
This is a good example of why Outex is built around lens-port modularity rather than camera-specific housing design. One camera can support multiple optical configurations simply by changing the relevant components.

Flat Optical-Glass Port or Dome?
Outex supports both approaches.
Flat Optical-Glass Port
For general X100 underwater photography, swimming pools, snorkeling, boating, travel and environmental protection, a flat optical-glass port provides the simplest starting point. Outex uses optical glass rather than a plastic/acrylic imaging window, and the port is positioned relative to the lens rather than floating far in front of it inside a large housing. Learn more on our FAQ page.
Optical-Glass Dome
A dome becomes particularly interesting for:
- wider-angle photography
- over/under photography
- split-level images
- subjects crossing the waterline
Outex offers 120mm and 180mm optical-glass dome options and uses interchangeable adapters or clamps to configure the dome relative to the lens. For an X100 + WCL-X100II setup intended heavily for over/under work, the Dome 120mm is generally sufficient given the smaller physical size of the lens and APS-C sensor.

The X100VI Adds Image Stabilization to the X100 Formula
Another major distinction between the newest X100VI and earlier generations is in-body image stabilization. Fujifilm rates the X100VI's 5-axis sensor-shift stabilization at up to six stops under its test conditions. That can be particularly valuable when you're photographing around water — your footing may not be stable, you may be floating, the subject may be moving, or the camera may be held away from your normal shooting position.
IBIS doesn't freeze a moving subject, but it can reduce camera shake and give photographers more flexibility when working with slower shutter speeds or difficult light. This makes the X100VI particularly attractive among the X100 family for creative work in demanding environments.
X100VI Video Underwater: More Capable Than You Might Expect
The X100 has historically been thought of primarily as a still-photography camera. The X100VI challenges that assumption. Fujifilm gives it internal recording options up to 6.2K/29.97p, 4K up to 59.94p, and Full HD high-speed recording up to 240p.
That makes it capable of producing:
- underwater travel footage
- swimming sequences
- lifestyle videos
- slow-motion splashes
- surf/watersports content
- short films
- behind-the-scenes footage
- vertical social content
For photographers who already carry an X100VI as their everyday still camera, the ability to move the same camera into water can create an entirely new content category without adding another camera system.
See How the Outex System Works
The flexible Outex concept makes much more sense when you see it in action.
Watch the Outex waterproof camera housing demonstration
Unlike a traditional camera-specific rigid enclosure, Outex lets the photographer manipulate camera controls through its flexible waterproof cover. The Outex Camera Pro Kit adds front and rear optical glass, full tactile camera/lens control, LCD/viewfinder access and compatibility with modular accessories including tripod, lighting, triggers and tethering. It is waterproof to 10 meters / 33 feet.
The camera in a demonstration doesn't need to be an X100 to show the principle. That's the point. The system changes around your camera rather than requiring a new rigid enclosure for every camera.
Weather Resistant Isn't the Same as Waterproof
This distinction is especially worth making for X100 owners. Fujifilm explains that the X100VI can be made weather-resistant when the AR-X100 adapter ring and PRF-49 protective filter are installed together. Weather resistance is useful for moisture, dust and adverse conditions.
But:
Weather resistant ≠ underwater waterproof.
If you intend to put the camera into a swimming pool, ocean, river or other submerged environment, you need a properly configured waterproof system designed for immersion. That's the role Outex plays.

Why Outex Instead of a Camera-Specific Fujifilm X100 Housing?
There's an interesting economic question behind any X100 underwater-housing purchase:
How long will you keep this exact X100 body?
A rigid underwater housing built specifically around an X100V or X100VI is fundamentally attached to the dimensions and controls of that particular camera. Outex isn't.
The Outex Camera Pro Kit is designed to work with virtually all cameras — DSLR, mirrorless, film, medium-format and cinema — as well as different lenses and optical configurations. That means you could:
Use an X100VI today.
Then later move to, or also choose to use:
Fujifilm X-T5
Fujifilm X-H2S
Fujifilm GFX
Sony Alpha
Canon EOS R
Nikon Z
a cinema camera
and continue reusing compatible Outex components.
For a photographer buying an X100 partly because they value compactness, simplicity and longevity, that's a particularly logical pairing.

Fujifilm X100 Underwater Housing FAQ
Is the Fujifilm X100VI compatible with Outex?
Yes, when appropriately configured. The fixed-lens X100 design requires matching the front connection to the camera/lens configuration rather than treating it exactly like an interchangeable-lens camera.
Is the Fujifilm X100V compatible too?
The X100V uses the same general fixed-lens X100 architecture and supports Fujifilm's AR-X100, WCL-X100II and TCL-X100II accessories. Confirm your exact model/setup with Outex before ordering.
What lens does the X100VI have?
The X100VI has a fixed FUJINON 23mm F2 lens, providing approximately a 35mm-equivalent field of view.
Can I change lenses on a Fujifilm X100?
Not in the conventional sense — the 23mm F2 lens is permanently attached. However, Fujifilm offers dedicated optical conversion lenses that change its field of view:
WCL-X100II → approximately 28mm equivalent
Standard lens → approximately 35mm equivalent
TCL-X100II → approximately 50mm equivalent
What Outex port size does the standard X100 require?
Fujifilm specifies a 49 mm filter connection using the AR-X100 adapter ring for the X100 series. Confirm the complete configuration with Outex when ordering.
What about the WCL-X100II?
The WCL-X100II has a 49 mm filter diameter.
What about the TCL-X100II?
The TCL-X100II has a 67 mm filter diameter.
Which X100 lens setup is best underwater?
There isn't one universal answer. The standard 35mm-equivalent lens is excellent for natural-looking environmental photography and portraits. For photographers who want a broader perspective and to work closer to subjects underwater, the 28mm-equivalent WCL-X100II is particularly attractive. The 50mm-equivalent TCL-X100II is more specialized and best suited to tighter compositions.
Can I use an Outex dome with the X100?
Yes, depending on the camera/lens configuration. See the Dome 120mm or Dome 180mm options. Dome setups should be selected for the exact optical combination being used.
Can I use the X100VI on an underwater tripod?
Yes. The Outex Pro system supports tripod mounting and modular tripod configurations.
Can the X100VI be tethered?
Fujifilm lists USB-C connectivity and compatibility with its Tether App and related software for the X100VI. Outex also offers waterproof cable pass-through accessories. The exact camera/software/cable workflow should be confirmed before configuring the system.
Is the X100VI waterproof by itself?
No. Fujifilm provides a weather-resistance configuration using the AR-X100 and PRF-49, but weather resistance should not be confused with protection for underwater immersion.
How deep can I take my X100 with Outex?
The Outex Camera Pro Kit is waterproof to 10 meters / 33 feet.
Can I reuse Outex if I change cameras?
Yes. That's one of Outex's primary advantages. The system uses interchangeable covers, optical ports and accessories designed to work across all Fujifilm cameras and lenses, as well as across different brands — film, DSLR, mirrorless, medium-format and cinema.

Take the Camera You Carry Everywhere Somewhere New
The Fujifilm X100 became popular partly because it removes complexity from photography. One camera. One lens. Traditional controls. A compact system you actually want to carry.
Outex lets you extend that philosophy into environments where an unprotected X100 shouldn't go.
Take it to the pool. Photograph a swimmer underwater. Bring it kayaking. Create portraits at the waterline. Use the WCL for a broader aquatic perspective. Add an optical-glass dome for dramatic split-level imagery. Protect the camera from rain, spray, sand and other demanding conditions.
And if the X100 eventually gives way to another camera, your Outex system doesn't necessarily have to go with it.
One compact camera. Three useful fields of view. An entirely new environment to photograph.
