The Nauticam NA-C400 is a professional underwater aluminum housing that builds on Nauticam’s extensive cinema housing lineup. The NA-C400 features the large N120 port opening shared with other Canon RF and EF-mount cameras such as the R5 II and R5C. This allows for the use of identical lens and port combinations when using a combination of RF-mount Canon cameras on a project with Nauticam housings.

Nauticam engineers obsess over placing essential controls where they are needed most so you never miss a shot looking for a button, dial or lever. Nauticam’s cinema lineup features large cinema-style lens control dials for precise control of focus and zoom. Exposure and capture controls are placed within easy reach of the ergonomic handles.

In addition to mechanical controls for Power, Zoom, Focus and Lens Release, the NA-C400 features electronic controls at the rear and both sides of the housing through the camera’s remote functionality. The left handle adjacent controls are for ‘Up’, ‘Down’, ‘ISO+’ and ‘ISO-’. Right handle adjacent controls are for ‘Rec’, ‘Fn3’, ‘Fn4’, ‘IRIS+’ and ‘IRIS-’. The main control board accesses ‘Left’, ‘Right’, ‘Up’, ‘Down’, ‘Set’, ‘1’, ‘2’, ‘MENU/Rec Review’.

The C400 features a detachable LCD screen that can be easily integrated into the NA-C400. The LCD monitor is supported inside the housing and mounted at the rear of the camera with a supplied bracket, allowing it to be easily viewed underwater through the shaded rear window — a streamlined filming solution.

The NA-C400 supports Nauticam’s optional HDMI 2.0 and 1.4 systems that can accommodate external monitors or recorders in Nauticam housings. SDI output is also available for either surface monitoring or supported monitors. The NA-C400 has 1× M28 and 5× M16 bulkheads to accommodate a variety of configurations to suit mounted or remote setups.

The NA-C400 can accommodate either the BP-A30N or BP-A60N batteries, or a combination of the BP-A30N and an FXLION NANO THREE 150Wh Micro V-Mount battery for extended runtimes.
