Sea&Sea Announces Housing for the Nikon Z7 II/Z6 II
By Ian Bongso-Seldrup, March 25, 2021 @ 08:00 AM (EST)

Sea&Sea has announced its new housing for the new Nikon Z7II and Z6II. The updated models feature more-powerful Expeed 6 processors, which increase both the continuous shooting speed and the buffer size, improve autofocus, and allow the cameras to capture 4K/60p internally. The cameras also gained an additional UHS-II SD card slot.

Like its predecessor housing, the MDX-Z7II works with the ports and gears for Sea&Sea’s MDX-series DSLR housings. The housing’s focus/zoom dial has two gears, one for F-mount lenses and one for Z-mount lenses: Using F-mount lenses requires the use of Nikon’s FTZ mount adapter.

The machined aluminum housing features integrated handles and includes a window for viewing the camera’s top LCD panel. As well as manual strobe triggering via sync cords, the housing accepts an optional hotshoe-mounted Optical YS Converter, allowing fiber-optic connectivity with compatible Sea&Sea strobes in both TTL and manual modes. Included with the housing are parts that allow the MDX-Z7II to accommodate the older Z7/Z6 cameras as well.

Consult your local dealer for pricing and availability.

Sea&Sea MDX-Z7II Underwater Housing for Nikon Z7II/Z6II
State-of-the-art housing for the full-frame mirrorless Nikon Z7Ⅱ/Z6Ⅱ/Z7/Z6 camera. Compact, compatible with the Optical YS Converter and ergonomically designed.


Ports and gears for the MDX series SLR housings can be used.

The MDX-Z7II/Z6II is compatible with the system chart for the MDX series SLR housings. You can utilize F-mount lenses with the mount adapter FTZ and ports/gears for the MDX series housings.

Compatible with Optical YS Converter/N1. TTL strobe photography possible.

An optional Optical YS Converter which converts the camera’s hot-shoe TTL signal into an LED light signal is compatible with the housing. Manual strobe photography is also possible.

Designed for both F mount lenses with the mount adapter FTZ and Z mount lenses.

The Focus/Zoom dial has two gears, one for F-mount lenses with the mount adapter FTZ and the other for Z mount lenses. The MDX-Z7II has been designed to take into consideration various Z mount lenses which will soon be available.

The camera’s upper control panel can be seen.

A window for the camera’s upper control panel is also incorporated. As brightness of the camera’s upper control panel has increased, the visibility is now greatly improved.


  • 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.
  • Pulling out the Focus/Zoom Dial gives sufficient room inside the housing to easily accommodate larger diameter lenses.
  • 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.
  • Equipped with the Optical Viewfinder 0.5x as standard. Other optional viewfinders such as Optical Viewfinder 0.66x,and 0.8x can be used.
    *Some vignetting occurs. When the VF45 and VF180 1.2x is mounted on housing, the  corners of the camera’s viewfinder cannot be viewed due to vignetting.
  • Sync Cord 2-pin Connector enables use of conventional hardwired Sync cable (Manual mode only).
  • Equipped with two sacrificial zinc diodes (one on the front case and the other on the rear) to prevent electrolysis damage.
  • Compatible with Z7/Z6 cameras by using the included parts
