Sea & Sea Canon 5D Mark IV Underwater Housing


The Sea & Sea 5D Mk IV Underwater Housing is constructed from corrosion-resistant aluminum with built in grips.  Sea & Sea has designed the buttons and important controls to be available at your fingertips.  They have also made the tension and distance for shutter adjustable to suit your needs. A built in leak sensor is also included. It has a great port lock system that is very easy to use.

* The housing is compatible with 5D Mark IV, 5DS and 5DS R.

TTL Converter

This housing is compatible with the Sea & Sea Optica YS Converter /C. This means you can get true TTL functionality and still fire quickly using fiber optic cables - the best of both worlds.

Sea & Sea Canon 5D Mark IV Housing - great features

  • The Port Lock prevents the port from turning or loosening, and the Port Lock lever is designed to avoid being unlocked accidentally.
  • The 5D Mark IV 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.
  • All controls have luminescence stickers which glow in the dark.
  • Equipped with the Optical Viewfinder 0.5x. Other optional viewfinders such as the VF180 1.2x, VF45 1.2x and Optical Viewfinder 0.8x can be used.
  • Sync Cord 2-pin Connector enables use of a hardwired Sync cable (Manual strobe mode only).
  • Accessory port (bulkhead) enables use of a Leak Sentinel (vacuum sensor).
  • Equipped with two sacrificial zinc diodes (one on the front case and the other on the rear) to prevent electrolysis damage.
  • Built-in leak sensor immediately alerts you to water coming into the housing.
  • Tripod screw mount is located on the centre bottom of the housing.
