Nauticam NA-S1RII Underwater Housing
For the Panasonic Lumix S1R II / S1II / S1IIE
The NA-S1RII brings Panasonic's redesigned true hybrid underwater — a 44MP 8.1K sensor that captures high-resolution stills and 8K 30p video with low rolling shutter, in a smaller, more hybrid-friendly body. A professional aluminium housing built on Nauticam's N120 port system, it carries over NA-S1R port and lens configurations, keeps every essential control under your fingers, and ships with vacuum and leak monitoring as standard.
Consider the NA-S1RII if you:
- Want a true hybrid — 44MP 8.1K stills plus 8K 30p video with low rolling shutter
- Shoot ProRes RAW / ProRes 422, Open Gate and real-time LUTs
- Are moving up from the NA-S1R and want your port and lens configs to carry over unchanged
- Want a pro aluminium rig with reliable safety monitoring

The Camera: Panasonic Lumix S1R II
New to the S1R II? Here's the context. Already know it well — skip to the housing below.
The Lumix S1R II is more redesign than evolution — both in capability and form factor. It's built around a 44MP 8.1K sensor for high-resolution stills and 8K video up to 30p with low rolling shutter, and can record ProRes RAW or 422 at selected resolutions and frame rates. Autofocus moves closer to its peers with phase detection and enhanced subject tracking, and a dedicated movie switch (below the drive-mode dial) frees the exposure dial for five custom positions with discrete stills and video settings.

The Housing
Lens compatibility and the N120 port system
The NA-S1RII is built on Nauticam's N120 port system, so anyone moving from the NA-S1R can carry over their port and lens configurations unchanged. The large port opening supports a wide range of L-mount lenses and integrates extensively with Nauticam's Water Contact Optics for the best possible underwater image quality.
Mission Control: every control within reach
The NA-S1RII places most essential functions within easy reach of the ergonomic handles. The camera's video/still mode selection — now on a dedicated switch — is operated by a lever atop the housing for rapid switching underwater. Thumb levers near the left and right handles actuate image review and AF-On, with further levers for AF-mode and switching between EVF and LCD also within easy reach.
HDMI output
The NA-S1RII is equipped with the large M24 bulkhead for Nauticam's HDMI system, connecting optional external monitors or recorders. Eight 1/4"-20 holes on top of the housing provide a solid base for mounting these or other larger accessories.
Flash triggering
For rapid-fire manual flash triggering, the NA-S1RII works with the Mini Flash Trigger (26305), which uses small LED units to fire external strobes through Nauticam Universal Fiber Optic Cables (26216).
Vacuum check and leak detection — standard
Nauticam's vacuum check and leak detection electronics ship with the NA-S1RII 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.
