Nauticam Nikon D850 Underwater Housing

Nauticam NA-D850 Underwater Housing for Nikon D 850 Full-Frame DSLR Camera

Innovation, ergonomics, and reliability are the hallmarks of the Nauticam brand and are brought to new heights with the Nauticam underwater housing for the Nikon D850 camera. Key controls are placed within an easy reach from the ergonomic, rubberized handles with unmatched ease of use. Controls on the housing are placed exactly where they should be for easiest access in water, regardless of the camera layout.

Unmatched Ergonomics

The right grip is mission control for the D850 camera, accessing many of the frequently used camera functions.  Oversized levers are identifiable by feel, allowing tactile operation while framing with the optical viewfinder. The most frequently accessed fingertip controls (Shutter Release, Main Command Dial, and Sub Command Dial, Video Record, and AF-ON) are located here. ISO, the primary exposure control used by DSLR video shooters, is accessed by a convenient thumb lever under the right grip. INFO, useful for calling up the camera settings on the 3.2" rear color LCD, is placed at the right thumb.

The new AF-Mode Lever is a significant improvement, and one based on feedback from Nauticam customers in the field.  Nikon AF Area modes have become so powerful that shooters are regularly switching between 3D Tracking, Auto Area AF, and Single Area modes.  The AF-Mode lever is now easily located by feel from the left handle.  A separate AF-M lever is positioned above this lever, and identifiable by feel.

A double thumb lever accesses playback and the assignable Fn2 Button.

Ease of Use

No system is easier to assemble or break down.  The camera drops into the housing with a quick release camera tray.  The camera tray has an extending bracket that allows the AF-M selector to be easily positioned to match the camera.  No controls need to be preset, as housing functions for dials and switches align automatically (on/off, af-m, still photo/video).   The large 120mm housing port opening allows even the largest popular pro Nikon wide angle lens (14-24 /2.8G) to be used, and the camera can even be mounted in the housing with this large lens attached.

Extensive Customization for a Tailored Ergonomic Experience

The Nikon D850 camera in a Nauticam NA-D850 housing offers four assignable push buttons (AF-ON, Fn1, Fn2, and Pv) that can all be accessed from the housing handles.

These custom functions can be overwhelming at first, but the creative options they unlock can be incredibly valuable in the field.  In short, these assignable buttons mean less time digging through camera menus to change camera functions, and more time capturing the scene as it unfolds.  There isn't a right way configure these systems.  Every photographer and shooting scenario has unique demands.

External Flash Triggering

The NA-D850 uses the same integrated LED flash triggering system found in NA-D5 and NA-D500.  This low profile housing mounted circuit board is convenient, easy to use, and reliable.

This optical flash trigger can fire at the full 7 fps of the camera, making it the ideal solution for the rapid fire fast action shooting that the D850 is so well suited for. Optical systems, with fiber optic cables linking the external flashes to the housing, are far more reliable than any electrical sync cable system. There are no connections to flood, or fragile wires to break, and nearly every popular underwater strobe supports optical triggering.
 
The LED trigger circuit board is mounted directly to the front of the housing, and connected to the camera with a hotshoe cable.  This new system is more powerful than the hotshoe mounted LED triggers used in the past, and is compatible with all currently available optically triggered flashes!  Powered by two CR2032 batteries, battery life is measured in the tens of thousands of flashes, driven by incredibly efficient electronics, up to 50,000 exposures.

Optional TTL circuit board

Users of legacy flashes without optical triggering are able to add accessory Nikonos (26074) or Ikelite (26075) style bulkheads for electrical flash sync.

Integrated Vacuum Check and Leak Detection System

The Nauticam vacuum check and leak detection system is shipped with NA-D850 as standard equipment.  Combined with an accessory vacuum valve (PN 25625), 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.
