Nauticam has been providing innovative aluminum housings since the original EOS-1D X with each evolution adapting to the ever changing role this camera plays in underwater image making. The NA-1DXIII adds a host of video-centric enhancements as well as more refined ergonomics and control access for all shooting situations.
While the EOS-1D X Mark III can capture incredible 5.5K 12-bit RAW internally, it can also output uncompressed DCI or UHD 4K video over HDMI at up to 30p. For those that prefer to use a more edit-friendly codec such as ProRes or DNX, the addition of an external monitor or recorder is an option. The NA-1DXIII features the large-bore M28 bulkhead that supports Nauticam's HDMI 2.0 cable system and supported monitors/recorders such as the Atomos Ninja V. The system also supports the HDMI 1.4 standard for use with non-recording monitor solutions such as the SmallHD 502 Bright and comes with an M28 to M16 step-down adapter pre-installed. See the sidebar for recommended monitor housings and necessary connection accessories.
The NA-1DXIII supports flash triggering via the built-in fiber-optic bulkheads atop the housing through the use of Nauticam's Manual or TTL flash triggers. The manual flash trigger provides high speed optical triggering of supported strobes using LEDs powered by an internal user-replaceable battery. For TTL, the Nauticam Canon TTL Flash Trigger can be used. The NA-1DXIII also comes with two M14 5-pin Nikonos bulkheads pre-installed along with a Canon to dual Nikonos bulkhead hot-shoe cable for electronic strobe triggering. The M14 bulkhead is installed along with an M16 to M14 step-down adapter.
The Nauticam vacuum check and leak detection system is shipped with NA-1DXIII as standard equipment. Combined with an accessory vacuum valve (PN 25625 for M16 or 25624 for M14), 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.
