Nauticam Underwater Housing NA-RX100IV for Sony RX-100 IV

The Nauticam NA-RX100IV Housing sets a new standard for compact camera underwater housing design. It is the ultimate refinement of the three models that came before it, with ergonomics, reliability, and control access improved in each new product.

Nauticam designs are always improving, and new features integrated into each new release. The ergonomic experience has been tailored for a photographer's right hand on the side of the housing, placing key controls literally at the users finger tips. Some users, especially those wearing cold water gloves, prefer shooting from handles such as the Nauticam Flexitray and Easitray. To better support this style of shooting, a set of stainless steel handle brackets and new mechanical shutter release trigger extension is included with every housing.

The features you'd expect are certainly present, like ergonomic design, the clearly labelled controls, sculpted shutter release and more. A updated fiber optic connection block is standard, as is the built-in vacuum check and leak detection system. Two accessory bulkhead ports support HDMI cables for an external monitor and the vacuum valve. The NA-RX1000IV is milled from a block of solid aluminum, then hard anodized. The result is a rugged and reliable piece of gear that will stand up to saltwater and the daily rigors of diving. Since the housing accesses all of the camera controls, including the front control ring, the user can take advantage of the enhanced programmability in the RX100 IV.

Vacuum Check System

The engineers at Nauticam managed to squeeze in the Nauticam vacuum monitoring and leak detection electronics. By default, it serves as an audible and visual leak detector, but add a Nauticam M14 Vacuum Valve, (p/n 25611) and it becomes a vacuum check system. The vacuum monitoring system provides early warning for any problem with watertight integrity - which means peace of mind when shooting underwater.


The RX100 IV now supports XAVC S Ultra High Definition (3840x2160) 24P/25P/30P video at up to 100 Mbps, as well as HD at up to 120 fps!  Focus peaking and zebra lines are available to assist in confirming sharp focus and correct exposure.  SLog2 Gamma is also available for professional color grading applications.

The standard NA-RX100IV housing supports HDMI out, via an optional HDMI bulkhead connected to the M16 accessory hole in the front of the housing. This means that the underwater videographer can use the excellent SmallHD 501 or 502 Monitors (in the NA-502S housing, p/n 17907), the Atomos Ninja 2 Recorder (NA-NINJA2 housing, p/n 17902), or even the Atomos Shogun UHD Recorder (Nauticam Housing p/n 17904). The RX100IV camera offers "clean" HDMI output, allowing high bit rate Apple ProRes recording at up to 4k 30P with Shogun. These monitors all provide a large, high quality display for judging focus and exposure, and the recording options available in the Atomos products unlock low compression recording formats for professionals.
