Capture the wonders of the undersea world at depths up to 328′ with your Nikon D850 digital SLR camera safely enclosed in theMDX-D850 Underwater HousingfromSea & Sea. With its streamlined design, the housing weighs only 101 oz and is close in size to the camera itself. The housing provides access to a wide range of camera functions via mechanical levers, dials, and push-button controls.

Frequently used controls such as the main command dial and the sub-command dial for manual photography, as well as video controls and AF lock, can be reached and operated while keeping both hands on the ergonomic grips. All dials are equipped with spring dampers to ensure secure, non-slip operation. Moreover, a built-in leak sensor alerts you immediately in the unlikely event of a breach in the waterproof seal.

The housing ships without a required lens port, and accepts a series of interchangeable ports from Sea & Sea. Various ports are available to accommodate macro, wide-angle, and zoom lenses.
