The Nikon D810
The D810 comes from the refinement and merging of the D800 and the D800E. The D810 maintains the same 36.3MP resolution from its revered predecessors, yet features a newly designed FX-format CMOS sensor that sees the complete removal of the optical low-pass filter (OLPF) from its design. This results in increased measured resolution, allowing D810 to fully realize the benefit of its 36 million pixels. This, combined with a new EXPEED 4 image processor, autofocus inherited from the D4S pro body, better battery life, and improved video shooting functionality make this a significant improvement on the best DSLR body available today.

The Nauticam NA-D810 Underwater Housing
The NA-D810 is an evolutionary marvel. A long list of pioneering engineering breakthroughs from previous Nauticam designs are now standard in NA-D810. The patented housing Locking Latch System has received acclaim worldwide for its ease and functionality. These recessed latches are equipped with safety locks, reduce bulk and require minimal physical effort to engage and release. Port changes have never been simpler than utilizing the Patented Nauticam Locking Port Release. No wrestling, no twisting, no misalignment – just seat and lock. Lens changes are also easily accomplished without removing the camera from the housing using the lens release button logically accessed on the housing front. The lightweight, rugged Nauticam handles are generously contoured with a durable over-mold process of comfortable non-slip rubber. The vacuum monitoring and leak detection circuit provides peace of mind by enabling the user to ensure that their housing is water tight before entering the water.
The NA-810 is a shining example of the best that Nauticam has to offer. Every control placement is well thought out. Every button, lever and switch considered not in terms of what is easier for the designer, but what is right for the shooter. An excellent example is the patent pending Multi Controller Pad that is located within easy reach of the right thumb. The device virtually recreates the Nikon multi selector on the back of the NA-810 housing allowing full multidirectional use of this powerful tool (including diagonal movement). No other manufacturer has this. Camera loading is "drop in" simple, with no controls requiring pre-alignment, allowing the fastest and easiest setup possible.
Core camera controls such as shutter release, aperture, shutter speed, live view, info, exposure compensation, depth of field preview, Fn, flash exposure compensation, focus mode, AF/M and zoom are located at the user's fingertips. Dual thumb levers, located on the right and left sides of NA-D810 pull important camera functionality from the back of the housing out to the handles. This allows quick access to Video Record, AF-ON (for thumb activated focus), ISO and Image Playback. Complete control of the camera is available from the ergonomic rubberized handles.
Integrated Vacuum Check and Leak Detection System
The Nauticam vacuum check and leak detection system is shipped with NA-1DXII 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.
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.
Located within easy reach of the right thumb, ergonomically operates the D810 Multi-controller joystick. Full directional control is available for fast focus point or menu selection.
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.
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.
Double Thumb Levers
Oversized double thumb levers, easily reached from the housing grips, and operational while wearing cold water gloves are a nauticam signature.
