INTRODUCING THE NA-D850 UNDERWATER HOUSING
Key camera controls are placed within an easy reach from the ergonomic, rubberized handles. An incredible amount of design resources go into crafting this layout, but that effort pays off 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.
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 Nikon D850 camera in a Nauticam NA-D850 housing offers four assignable pushbuttons (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.
EASE OF USE
No system is easier to assemble or break down. The camera drops into the housing with a quick release camera tray. 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. Premium Professional Optics Experienced shooters know a camera is only as good as the lens in front of it, and the same is true when choosing optics for an underwater camera system. Four optically coated glass dome ports (250mm, 230mm, 180mm, and 140mm diameters) and a series of acrylic ports support popular lenses from Nikon, Sigma, and Tokina. Port configurations are extensively tested at Nauticam to determine the ideal extension ring length for best performance.
NA-D850 SPECIFIC FEATURES
The most frequently accessed fingertip controls (Shutter Release, Main Command Dial, and Sub Command Dial, Video Record, and AF-ON) are located here. ISO is accessed by a convenient thumb lever under the right grip. INFO is placed at the right thumb.
NEW AF-MODE LEVER
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.
INTEGRATED LED FLASH TRIGGER
The NA-D850 uses the same integrated LED flash triggering system. 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. The LED trigger circuitboard is mounted directly to the front of the housing, and connected to the camera with a hotshoe cable.
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 circuitboard 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. With good batteries, we expect 3-5 years of service, up to 50,000 exposures.
Users of legacy flashes without optical triggering are able to add accessory Nikonos (26074) or Ikelite (26075) style bulkheads for electrical flash sync. These bulkheads plug into the LED trigger board for clean cable routing, and reliable connection.
NA-D850 is also compatible with the Nauticam TTL Converter (26308). A user installable upgrade, the converter provides accurate automatic TTL flash exposure with a number of popular flashes, and offers both optical and electrical strobe triggering in a single unit!
Optical triggering, using LEDs integrated into the board and fiber optic cables, works well with modern flashes like Inon Z-240, Sea & Sea YS-D2, and more. Electrical triggering supports Ikelite DS- and Sea & Sea YS-250 strobes connected via an electrical sync cord.

NAUTICAM'S AWARD WINNING FEATURES
PATENTED PORT LOCKING SYSTEM
Unveiled on the very first Nauticam DSLR housing in 2009, this locking lever has become a signature of the Nauticam brand. No twisting or threading action is required to mount a port, and it locks securely in place with this lever. Nauticam also offers locking port extensions, meaning a dome will never twist, even when used with a long extension ring.
HOUSING LOCKING LATCHES
The industry's easiest to use housing closure system, requiring very little hand strength to operate, secures the housing back in place. The latches are safely locked to prevent accidental opening, but are easy to open when needed for a quick battery or memory card change.
STAINLESS STEEL HANDLE BRACKETS
Stiffening handle brackets are included with the housing. These brackets eliminate any flex or wobble when using big strobes, and provide multiple attachment points for lanyards or other accessories.
ERGONOMIC RUBBERIZED GRIPS
Another legendary Nauticam feature, these rubberized grips have been used every Nauticam DSLR housing release, and are some of the most comfortable in the business. The zoom / focus control knob also features this same soft touch rubber coating for improved tactile feel.
INTEGRATED VACUUM CHECK AND LEAK DETECTION SYSTEM
The electronic Nauticam vacuum check and leak detection system is shipped 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 colour 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.
