Nauticam Sony FX5 Underwater Housing
A purpose-built Sony FX5 underwater housing with the Nauticam N100 port system, HDMI monitor support, cinema-focused controls, and a 100m depth rating.
Designed for underwater cinematographers looking to capture cinema-grade footage, the Nauticam NA-FX5 Housing unlocks the full capabilities of Sony’s compact Cinema Line camera beneath the surface. Building on the ergonomic design and success of the Sony fx3 underwater housing, this precision-machined aluminum underwater housing allows you to record internal 16-bit X-OCN RAW and 3:2 Open Gate 5K video depth-rated down to 100 meters without external recorders.
Key Features & Highlights
- Mission Control Ergonomics: Critical exposure controls, white balance, and menu dials are directly accessible from the integrated handles without taking your hands off the rig, including a rear REC lever placed under your right thumb.
- N100 Port System Integration: Seamlessly pairs with Nauticam’s premium water-contact optics like the WACP-1B, WACP-C, and WWL-1B for corner-to-corner clarity. You can easily reference the nauticam port chart to select compatible port extensions and adapters for your specific Sony E-mount lenses.
- Advanced Connectivity: Features front M24 and M16 accessory ports along with a rear M16 port. Supports HDMI 2.0/1.4 external monitor housings and surface power delivery via a USB-C Bulkhead simultaneously.
- Vacuum Check & Leak Detection System: Ships with built-in electronics providing temperature-compensated real-time optical and acoustic monitoring to ensure seal integrity before and during your dive.
- Extensible Mounting Points: Includes twenty 1/4"-20 threaded mounts and one M10 mount across the body for mounting video lights, monitors, and tripod plates directly.
Constructed with Nauticam's signature patented port locking lever and rotary enclosure locks, this nauticam housing delivers maximum durability and reliability for demanding production environments. Whether you need a standalone setup or a complete nauticam underwater housing rig with external monitoring, the NA-FX5 provides full control over Sony's latest full-frame sensor technology underwater.

Nauticam NA-FX5 Quick Specs
Features That Matter Underwater

Cinema Controls Without Rebuilding Your Grip
Underwater video becomes frustrating when exposure or record controls force you to let go of the handles every time conditions change. Nauticam positions the major shooting controls around the grips, including a rear REC lever and access to the FX5's multifunction dial.
- Fast access to record, exposure and menu functions
- Useful when following moving animals or shooting in current
- Stiffened handles help support heavier monitor and lighting builds
- Most camera controls are accessible externally
N100 Optics Give the FX5 Room to Grow
A cinema housing is only as useful as the lenses and ports you can put in front of it. The NA-FX5 uses Nauticam's N100 port system, giving Sony shooters access to dome ports, macro ports, port adapters, and compatible water-contact optics.
- Supports both wide-angle and macro system builds
- Useful for existing Nauticam Sony N100 owners
- N100-to-N120 adapters expand selected port options
- Lens-specific port chart prevents guesswork


Built for External Monitoring
A large external monitor makes a major difference when judging composition, exposure and focus through a mask. The NA-FX5 provides an M24 accessory port for Nauticam HDMI systems and supports both HDMI 2.0 and HDMI 1.4 configurations.
- HDMI 2.0 and HDMI 1.4 support
- Compatible monitor-housing routes are available
- Separate accessory ports leave room for additional system functions
- USB-C surface-power bulkhead can be added in supported configurations

Nauticam Sony FX5 Housing FAQ
Does the Nauticam NA-FX5 fit the Sony FX5?
Yes. The NA-FX5 is designed specifically for the Sony FX5 camera. The correct lens port still needs to be selected separately.
Will a Sony FX3 underwater housing fit the Sony FX5?
No. The Sony FX5 requires its dedicated NA-FX5 housing. An existing Nauticam FX3 owner may still be able to reuse compatible N100 ports and accessories.
What port system does the Nauticam Sony FX5 housing use?
The NA-FX5 uses the Nauticam N100 port system. The exact port, extension ring and gear depend on the Sony E-mount lens you plan to use.
Does the NA-FX5 include a vacuum system?
Vacuum monitoring and moisture-detection electronics are built into the housing. The optional Nauticam 25625 M16 Vacuum Valve II is required to pull and maintain a test vacuum.
Can I use an external monitor with the Sony FX5 underwater?
Yes. The NA-FX5 supports HDMI 2.0 and HDMI 1.4 accessory configurations for compatible Nauticam monitor housings and cables.
How deep can the Nauticam FX5 housing go?
Nauticam rates the NA-FX5 to 100 meters, or approximately 328 feet.
How do I know which Nauticam port I need for my FX5 lens?
Match the exact lens to the current Nauticam Sony E-mount port chart rather than selecting by lens size alone. Bluewater Photo can confirm the complete port, extension and gear combination before you order.
Is the NA-FX5 negatively buoyant underwater?
Nauticam lists the housing at approximately 0.3kg negative in water with the camera and battery. Your finished rig will change once a lens, port, monitor, arms and lights are installed.
