The Nauticam NA-C50 Underwater Housing

The NA-Cbo underwater housing upholds Nauticam’s dedication to innovation. Essential controls are conveniently accessible via ergonomic handles, facilitating an efficient setup that optimizes time spent in the water and minimizes time spent on rig maintenance. The N120 port system accommodates Canon RF and EFMount lens. For EF lens the RF to EF adapter with a variable ND filter can be used with an optional control kit. Nauticam’s extensive range of ports and in-house corrective optics complement the NA-C50’s capabilities. When equipped with an accessory vacuum valve, the integrated vacuum check and leak detection system provides continuous updates on the housing’s watertight integrity. A vacuum system reset switch, located beneath the tray, eliminates the necessity to open the back of the housing during lens or port changes. The NA-C50 supports additional mounting with a built in 1/4-20 cheese plate.

Lens ports & wet lenses

When you know what lens you want to use then you check Nauticam's updated port charts to find the recommended lens port or wet lens solution (sold separately).

There are different port charts depending on your underwater housing's port size (N120, N100, N85 or N50), and which camera brand. You will probably find more than one port combination, or wetlens solution.

Mission Control

Nauticam engineers are obsessed with getting the underwater image maker unfettered access to all the necessary controls, with as many within easy reach of the ergonomic rubberized handles. This Mission Control philosophy extends to the NA-R5 C where a dual thumb lever and dual sub-lever are placed by the right handle. The upper thumb lever activates the "AF-On" and the lower the "Menu" or "Q" buttons while the sub-lever corresponds to the "M-Fn" and "Record" buttons. Near the left handle is a thumb lever for "Playback" as well as a dedicated switch to change from using LCD to the EVF.

Large knurled and rubberized control dials access the camera's "main" and "sub" command dials. The two-stage trigger allows for smooth focus and firing activation. Additional buttons for "Menu", "Focus Point Selection" and others are also easily reached from the handles.

An optional 16703 Control Kit for the NA-R5C is available to use with the Drop-In Filter Mount Adapter EF-EOS R. You can access the Canon Control Ring and Drop-In Filter Mount Adapter from the top left side (ADAP FN knob).

External Battery Pack

To support 8K 60p internal Canon Cinema RAW Light recording, an external power source is required. At the bottom of the housing is space to accomodate a USB-C power bank. Here are two known compatible batteries with more to come:

Anker PowerCore III 19,200mAh Huge Cell Capacity 45W Power Delivery Portable Charger (Dimensions: 169x79x22.4mm)
ZMI 20000mah 65W PD battery (Dimensions: 160.4x81.8x21.5mm)

Flash Triggering

Flash triggering is achieved via one of two optional Flash Triggers, a manual LED trigger (PN 26301) or a TTL Flash Trigger (PN 26321) that use the built-in fiber optic bulkheads with optional fiber-optic cables to trigger supported strobes. For controlling strobes that do not support fiber optic flash triggering, a variety of legacy hot-shoe flash control bulkheads are available.

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection electronics are shipped with the NA-R5C as standard equipment. Combined with an optional accessory 25625 M16 Vacuum Valve II this monitoring system provides constant updates on the water tight and safe-to-dive status of the housing. A simple color coded LED lighting system lets the user know that the vacuum is solid, or that the housing is losing vacuum. Leak detection is built into the same circuit, so if there is water intrusion, an audible and visual indication will occur.

The Nauticam system is temperature compensated, eliminating false alarms caused by a change in outside temperature, or from a camera heating up on an action packed dive.
