This is a specialized underwater housing for photographers building around the Hasselblad X2D II 100C camera. Its biggest appeal is the ability to take Hasselblad's 100MP medium-format system underwater while retaining access to the controls, lenses, ports and external lighting needed for serious underwater still photography.
Best For
Experienced underwater photographers, commercial shooters and fine-art photographers who specifically want the resolution and image characteristics of the Hasselblad X2D II 100C underwater.
Main Advantage
It combines a purpose-built Hasselblad housing with Nauticam's N120 optical system and access to XCD lens controls, creating a complete platform rather than simply protecting the camera.
Compatibility
Designed specifically for the Hasselblad X2D II 100C and built around the N120 Hasselblad XCD port system. Ports, extensions and lens gears must be matched to your specific XCD lens.
Important to Know
The port and lens gear are not part of the housing itself. Optical strobe triggering also requires Nauticam's optional Hasselblad flash trigger, and the currently listed optical trigger is manual rather than TTL.

What You Need to Know
Compatibility
The NA-X2DII fits the Hasselblad X2D II 100C. Your lens then determines the required N120 port, extension and gear or control-ring components. Do not order the housing and port independently without checking the complete lens configuration.
What You'll Need
In addition to the camera and lens, expect to need the correct N120 port and any required extension or lens gear. Strobe shooters will also need the appropriate triggering system and cables. We strongly recommend adding the optional vacuum valve for pre-dive seal verification.
Who Should Choose It?
Choose this system if the X2D II 100C is central to your photography and image quality is more important than minimizing system size, travel weight or cost. Divers prioritizing a smaller travel system may be better served by a full-frame or smaller-format camera platform.
Compatibility Resources
Nauticam maintains a dedicated N120 Hasselblad XCD port chart showing the appropriate ports, extension rings and lens-control components for supported lenses. Because configurations vary by lens, we recommend checking the current chart before ordering.

Nauticam Hasselblad X2DII 100C Underwater Housing Overview
The Nauticam NA-X2DII is a professional aluminum underwater housing designed specifically around the Hasselblad X2D II 100C. That distinction matters: the X2D II is a 100-megapixel medium-format camera, so building a useful underwater system involves more than fitting the camera inside a waterproof shell. Lens choice, underwater optics, control access, strobe synchronization and system balance all become important parts of the setup.
Nauticam uses its N120 Hasselblad XCD port system for this housing. Depending on the lens, the setup may use a dedicated gear or control-ring component together with the appropriate port and extension. This gives photographers access to XCD lenses for subjects ranging from wide-angle scenes to close-up work, but it also makes correct system configuration particularly important.
The housing places important X2D II controls around the handles, including front and rear command controls, AF-ON access, lens control and a programmable front control. For photographers working quickly underwater, keeping these adjustments close to the hands is far more useful than simply having every button mechanically reproduced somewhere on the housing.
Another unusual benefit of the Hasselblad system is its XCD leaf-shutter design. With compatible XCD lenses, flash synchronization is available at shutter speeds up to 1/4000 second, giving experienced strobe photographers considerably more flexibility when balancing artificial light against bright ambient conditions.
Key Features
- Purpose-built for the Hasselblad X2D II 100C so critical camera controls remain accessible underwater.
- N120 Hasselblad XCD port system supports configurable port solutions for compatible XCD lenses.
- Ergonomic control placement keeps major exposure, focus and lens controls close to the handles.
- 100m depth rating supports demanding recreational and professional dive use.
- Built-in moisture alarm and leak detection provide an additional warning layer inside the housing.
- Optional M16 Vacuum Valve II allows the housing seal to be checked before entering the water.
- Optional optical or electrical strobe triggering allows the lighting system to be configured around the photographer's needs.

Designed Around Real Underwater Shooting
Controls Where You Can Actually Reach Them
Nauticam provides access to the X2D II's front and rear scroll controls, AF-ON, a front custom control and XCD lens functions. The practical benefit is faster exposure and focus adjustment without repeatedly moving your hands away from the housing grips.
N120 Optics for a 100MP Camera
The X2D II's resolution makes underwater optical choices especially important. Nauticam's N120 system provides dedicated configurations for supported XCD lenses and access to selected Nauticam water-contact optics. The correct lens, port, extension and gear combination should always be confirmed before purchase.
Flexible Strobe Synchronization
The optional Hasselblad optical flash trigger fires through the housing's fiber-optic connections and is currently specified for manual flash control. Hardwired electrical triggering can also be configured with compatible optional bulkhead components. With XCD leaf-shutter lenses, the camera can synchronize flash at shutter speeds up to 1/4000 second.

Frequently Asked Questions
Which camera fits the Nauticam NA-X2DII housing?
The NA-X2DII is designed for the Hasselblad X2D II 100C. Do not assume compatibility with other Hasselblad camera bodies simply because they look similar.
Does the housing include a lens port?
No. The correct N120 port, extension and any required lens gear depend on the XCD lens you plan to use and are selected separately.
Does the NA-X2DII include a vacuum valve?
The housing includes moisture-alarm and leak-detection electronics, but the M16 Vacuum Valve II is an optional accessory. Adding the valve enables a pre-dive vacuum seal check.
Can I use underwater strobes with the Hasselblad X2D II?
Yes. Nauticam lists an optional manual Hasselblad flash trigger for fiber-optic strobe triggering and optional components for hardwired electrical triggering.
Does the Nauticam Hasselblad flash trigger support TTL?
Nauticam currently specifies its Hasselblad optical flash trigger as a manual trigger. Do not assume TTL functionality unless a compatible TTL solution is specifically confirmed.
How deep is the Nauticam NA-X2DII rated?
Nauticam rates the housing to 100 meters.
How do I know which port I need?
Start with the exact XCD lens and then check Nauticam's current N120 Hasselblad XCD port chart. Bluewater Photo can also help confirm the port, extension and gear combination before you purchase.
