Innovation, ergonomics, and reliability are the hallmarks of the Nauticam brand, and this housing is made with just that in mind so it will suit the amazing Nikon D850 camera!
Key camera controls are placed within an easy reach from the ergonomic, rubberized handles. Controls on the housing are placed exactly where they should be for easiest access in water, regardless of the camera layout.
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. 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!
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 Monitoring and Leak Detection
Circuitry included as standard equipment provides constant monitoring of water tight integrity when combined with an optional Nauticam M16 Vacuum Valve II (PN 25625). A simple vacuum reset pushbutton placed in the port mount allows the vacuum system to be calibrated and initialized from the housing front.
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.
