The Nauticam NA-D850 Underwater Housing
Innovation, ergonomics, and reliability are the hallmarks of the Nauticam brand. Every new underwater housing design is carefully crafted based on feedback from Nauticam users around the globe. Feedback gained from the knowledge and experience of Nauticam owners results in every new housing design being better than the last.
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 Nikon D850, 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 in a Nauticam NA-D850 underwater 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. There isn't a right way configure these systems. Every photographer and shooting scenario has unique demands.
External Flash Triggering
The NA-D850 underwater housing uses the same integrated LED flash triggering system found in NA-D5 and NA-D500 underwater housings. 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!
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.
