Sea & Sea Nikon D850 Underwater Housing

* Limited Stock available *


The Sea & Sea Nikon D850 underwater housing has been expertly engineered and machined to be lightweight without sacrificing functionality. Weighing 11% less than the Sea & Sea Nikon D810 housing, it is also lighter than both the Nauticam and Aquatica aluminum D850 housings. This makes it awesome to travel with when going on dive trips.

Sea &Sea D850 Housing Key Features:

  • Smaller Size and Lighter Weight - The D850 housing has been machined to be extremely lightweight. In addition Sea & Sea revised the internal design in order to reduce the overall size of the housing in addition to limiting weight. Without handles, the housing weighs only 6.2lbs (2.85kg).
  • Controls Within Reach - Improvements to locations of important controls have been updated, allowing for easy reach while maintaining a grip on the housing handles. The frequently used Main and Sub-Command dials are now located directly on the right side of the housing. ISO, REC and other camera functions can be operated by external levers whilst holding the grips.
  • Quality Build - all dials in this housing include a spring (damper) which prevents slipage, even if the camera dimensions are slightly different than the spec or as parts begin to wear over time. The buttons and controls all include luminescent stickers which glow in dark enviornments, making it easy to identify your controls during night dives. The housing includes a leak sensor, and sacrifical zinc anodes to prevent damage from electrolysis.
  • Superior TTL Control - The Sea & Sea Optical YS Converter/N1 can be built into the housing which converts the camera’s hot-shoe TTL signal to a light signal for accurate TTL controls with your underwater strobes. Both TTL and manual strobe modes can be used and controlled from the housing using a Fiber-Optic Cable II.

Other Features of the Housing:

  • Easy to remove handles, makes packing for travel a breeze.
  • The Port Lock prevents the port from turning or loosening and the Port Lock lever is specifically located to avoid being unlocked accidentally.
  • The housing is equipped with a lens-lock release button which makes it possible to change lenses easily, without opening the housing.
  • The camera’s diopter adjustment dial can be operated from outside the housing. This feature is useful when two or more people with different eyesight use the housing.
  • Pulling out the Focus/Zoom Dial gives sufficient room inside the housing to easily accommodate larger diameter lenses.
  • Equipped with the Optical Viewfinder 0.5x as standard. Other optional viewfinders such as Sea & Sea VF45 Viewfinder and Sea & Sea 180 Degree Viewfinder can be used.
  • Includes a sync cord bulkhead.  The sync cord 2-pin connector enables use of conventional hardwired Sync cable (Manual mode only).
  • Accessory port enables use of Leak Alarm Unit.
  • Tripod screw mount is located on the center underside of the housing.
  • Depth rating of 100m / 330ft
