Nauticam NA-Z9 Underwater Housing
For the Nikon Z9
The NA-Z9 brings Nikon's flagship hybrid into the water — a 45.7MP stacked sensor with no-blackout 20fps RAW shooting and 8K video. Built on Nauticam's N120 port system, it runs both native Z-mount and legacy F-mount glass (via the FTZ adapter), keeps every essential control under your fingers, and ships with vacuum and leak monitoring as standard.
Consider the NA-Z9 if you:
- Want Nikon's flagship — 45.7MP stacked sensor, no-blackout 20fps RAW, 8K video
- Shoot both native Z-mount optics and legacy F-mount glass via the in-housing FTZ adapter
- Mix high-speed stills with internal 8K / 4K video
- Need reliable safety monitoring for demanding dives

The Camera: Nikon Z9
New to the Z9? Here's the context. Already know it well — skip to the housing below.
The Nikon Z9 is Nikon's flagship full-frame mirrorless, built around a 45.7MP stacked CMOS sensor and the EXPEED 7 processor. It drops the mechanical shutter entirely for a true no-blackout, "Real-Live" EVF up to 3,000 nits, delivers 20fps RAW and 120fps 11MP JPEG bursts, and records up to 8K video. Autofocus works down to -8.5EV with advanced 3D subject tracking and auto subject detection across more than 400 points.

The Housing
Lens compatibility and the N120 port system
The NA-Z9 is built on Nauticam's N120 port system for native Z-mount full-frame lenses. For F-mount glass, the FTZ adapter sits inside the housing, giving the same port configuration as a Nikon F-mount DSLR system. Two lens-release buttons — one for F, one for Z — let you change lenses through the port without removing the camera; the camera only comes out when installing or removing the FTZ adapter itself.
Mission Control: every control within reach
Nauticam's Mission Control philosophy puts the essentials within easy reach of the ergonomic handles. By the left handle, finger-actuated levers cover the customisable Fn1 and Fn2 buttons plus AF-Mode, and a double thumb lever triggers Playback and DISP. On the right, a double thumb lever handles AF-On and Record, with a recessed lever for ISO and a forward-placed lever for Fn1. Easy setup means more time in the water and less time working on your rig.
Flash triggering
Trigger strobes through the built-in fiber-optic bulkheads, paired with the optional Nikon TTL converter and fiber-optic cables. For hardwired connections, M14 bulkheads with micro connectors are available for use with the Nikon TTL converter.
HDMI output
As a true hybrid platform, the NA-Z9 connects external monitors and recorders via the large M24 bulkhead, which supports both HDMI 1.4 and HDMI 2.0.
Vacuum check and leak detection — standard
Nauticam's vacuum check and leak detection electronics ship with the NA-Z9 as standard. Combined with the optional 25625 M16 Vacuum Valve II, the system continuously reports the housing's watertight, safe-to-dive status through a color-coded LED: solid vacuum, or vacuum loss. Leak detection runs on the same circuit, so any water intrusion triggers an audible and visual alarm.
The system is temperature-compensated, so it won't throw false alarms from a change in water temperature or from the camera heating up on an action-packed dive.
