Nauticam Sony A7 V Underwater Housing
Designed for shooters who care as much about control fidelity as image quality, the Nauticam Sony A7 V underwater housing solves the real problem of operating a high-performance mirrorless camera reliably at depth. This aluminum underwater camera housing provides true fingertip access to all critical camera functions, allowing exposure, focus, and shooting adjustments to be made directly from the handles—no awkward reaches, no broken shooting rhythm. For experienced users building a serious Sony underwater camera housing system, this is where Nauticam’s reputation is earned.
Despite its professional-grade construction, the housing remains relatively compact at 340mm (W) × 170mm (H) × 127mm (D), with a 2.7kg weight in air and a near-neutral –0.2kg buoyancy in water (with camera and battery installed). Rated to 100 meters, it’s clearly aimed at advanced recreational and technical divers who need confidence well beyond typical depth limits. The N100 port mount opens the door to Nauticam’s full ecosystem of water-contact optics, making this nauticam underwater housing a strong long-term platform rather than a single-camera solution.
Ergonomics are a defining strength here. Borrowing heavily from Nauticam’s pro DSLR housings, the NA-A7V places the most-used controls exactly where your hands already rest. Dials feature rubberized finger grooves, levers operate smoothly even with gloves, and the overall layout feels like a seamless extension of the camera rather than a compromise imposed by the housing. This balance of precision, durability, and system flexibility is why many experienced shooters consider Nauticam among the best underwater camera housing options available—provided you’re ready to commit to the ecosystem that comes with it.
Key Features:

HDMI Connectivity
The NA-A7IV housing features the larger opening, M24 bulkhead which allows you to use Nauticam HDMI 2.0 & 1.4 cables to connect to your recorders such as Atomos Ninja V, Shinobi & SmallHD 503

Mission Control
Nauticam has a reputation of providing excellent ergonomics on all of their housings, and the housing for the Sony A7 IV lives up to their name. Buttons, levers and dials are easily accessible and very intuitively located. Even while wearing thick gloves the housing controls are very easy to operate.

Patented Port Locking System
The locking lever has become a signature of the Nauticam brand. No twisting or threading action is required to mount a port, and it locks securely in place with this lever.

Integrated Vacuum Monitoring and Leak Detection
Combined with a vacuum valve (NAU-25624), this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing via a simple color-coded LED lighting system. Green means go, safe to dive!
Other Features:
- Premium Professional Optics - Nauticam’s professional water-contact optics deliver the highest underwater image quality.
