Use your Sony Alpha a7R IV mirrorless digital camera to capture brilliant photos and video of the undersea world with the Aquatica A7rIV Underwater Housing. It features a depth rating of 300', which can be upgraded to 450' with Aquatica's optional spring kit, and is equipped with a Surveyor Vacuum System, with a vacuum pump, sensor, and alarm so you can check the integrity of your seal before you dive. An Ikelite manual connector enables the attachment of an optional external strobe via sync cord.

The standard, coated eyepiece offers a full view of the camera's viewfinder. The housing provides access to virtually all camera functions via mechanical controls, and offers an ergonomic design with two grips for secure handling and attachment of optional lighting arms. Built for durability, especially resistance to corrosion, the housing is constructed from anodized, machined aluminum and stainless steel.

The A7rIV housing ships without a required lens port, though various interchangeable ports are available for different lenses. For full compatibility, see the Port Chart.
