As always, the focus of Nauticam housings is on the customer's enjoyment during use. Emphasis is put on ergonomics with easy to reach controls, comfortable handles and full functionality. The NA-D850 offers complete control, molded rubberized handles and positioning of controls for reach with any hand size.
Ease of Use:
The Nauticam system is extremely easy to assemble and break down. A quick release camera tray holds the camera securely in the housing, no controls need to be preset and housing functions for dials and switches align automatically.
The large 120mm housing port opening allows all lenses, even the widest of Nikon Pro lenses to be used as well.
The right handle is your base of operations for all primary camera functions on the NA-D850. Nauticam has created oversized leverls, easily identifible by feel which allows for quick operation without removing your eye from the viewfinder.
The most frequently accessed controls (Shutter release, Main Command Dial, Sub Command Dial, Video Record, and AF-ON) are all located there. In addition the ISO control is accessed by a convenient thumb lever under the right grip. The INFO button is accessed from the right as well, which is useful for calling up camera settings on the rear LCD.
An improved AF-Mode lever is positioned on the left of the housing, easily identifible by feel allowing for quick switching between the various AF modes on the D850. In addition a separate AF-M lever is positioned above the AF-Mode lever. Also on the left is a double thumb lever for playback and the assignable Fn2 button.
The Nauticam housing includes a high quality optical glass viewfinder which works well for many users. However for those who want the benefit of the magnified viewfinder with the adjustable diopter, both the "straight" 180° viewfinder and the "angled" 45° viewfinder work great with this housing. Dioptric adjustment allows you to refine the viewfinder perfectly to your eye. Switching between viewfinders is easy and does not require any special tools.
The NA-D850 uses the same integrated LED flash trigger that is in the Nauticam NA-D5 housing. This trigger is mounted inside the camera housing, and allows firing of strobes to match the full 7fps speed of the camera burst so you never miss a shot.
Using fiber optic cables offers consistent light transmission without any additional points of entry into the housing, and these cables are smaller and less fragile than bulky electronic sync cables.
If you are using an older underwater strobe that does not allow for optical triggering, you can still add the accesory Nikonos (NAU-26074) or Ikelite (NAU-26075) style bulkhead and use electronic sync cables. These bulkheads plug directly into the LED trigger circuit board for clean cable routing and a reliable connection.
Optional TTL Converter
The NA-D850 is compatible with the Nauticam TTL Trigger (26308). This is a user installable upgrade, which provides accurate automatic TTL flash exposure from a number of popular underwater strobes with the ability to fire via electronic sync cord and fiber optic cables.
Compatible strobes include the Sea & Sea YS-D2J, Inon Z-330 and more. The YS-250 is also compatible via electronic sync cables.
Patented Port Locking System
No twisting or threading action is required to mount a port, and even the largest dome locks securely in place with this lever. Nauticam also offers locking port extension rings, meaning a dome will never twist.
Housing Locking Latches
The industry's easiest to use housing closure system, requiring very little hand strength to close, secures the housing back in place. The latches are safely locked, but easy to open for a quick battery or memory card change.
Multi Controller Pad
Located within easy reach of the right thumb, virtually recreates the Nikon D850 multi selector allowing full multidirectional use of this powerful tool. No other manufacturer has it, and with 55 user selectable focus points to choose from, photographers need it.
Integrated Vacuum Monitoring & Leak Detection System
Circuitry included as standard equipment provides constant monitoring of water tight integrity when combined with an optional Nauticam M16 Vacuum Valve II (PN 25625).
Vacuum Reset Button in Port Mount
A simple vacuum reset pushbutton placed in the port mount allows the vacuum system to be calibrated and initialized from the housing front. Ideal for quick lens swaps!
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, a hand strap, and other accessories.
Ergonomic Rubberized Grips
Another excellent Nauticam feature, these rubberized grips have been used with every Nauticam DSLR housing release. Their ergonomic shape and soft rubberized coating prevents hand fatigue, even on long dives.
Clear Control Labeling
All camera controls are clearly labled, allowing for easy identification while shooting.

The Nikon D850 offers four assignable pushbuttons (AF-ON, Fn1, Fn2, and Pv) which can also all be accessed from the Nauticam NA-D850 housing. While custom features can often be overwhelming, they can also really improve the user experience and unlock more creative options that are extremely valuable while out shooting.
You can configure these buttons however you like, but if you are looking for some starting points, here are a few recommendations from Nauticam to take advantage of these advanced set ups.
