Underwater camera housing

Watertight camera housings are essential for underwater photography, protecting gear from pressure and corrosion.

About this subject

Underwater camera housings, often simply called housings, are enclosures that allow standard or purpose-built cameras to operate submerged. They are typically made from anodized aluminum, polycarbonate, or high-strength plastics, chosen for durability against pressure and saltwater corrosion. Each housing is custom-molded for a specific camera model, using rubber O-rings to seal out water, even at depths exceeding 100 meters.

Underwater photography gained momentum in the 1950s with cameras like the Calypso (predecessor of the Nikonos). Before that, photographers relied on bulky, handcrafted brass-and-glass boxes. Today, leading brands such as Ikelite, Nauticam, and Aquatica produce modular systems with interchangeable lens ports and external controls for focus, zoom, and shutter.

Beyond recreational use, housings are critical in marine biology, underwater archaeology, infrastructure inspection (dams, oil rigs), and search-and-rescue operations. Proper maintenance involves regular cleaning and lubrication of O-rings to prevent leaks. A seal failure can destroy the camera and, in integrated lighting and communication systems, pose safety risks to divers.

Frequently Asked Questions

What is the maximum depth an underwater housing can handle?

It varies by model, but aluminum or polycarbonate housings typically support 40 m to over 100 m. Professional housings can reach 300 m.

Can I use any camera in a housing?

No. Each housing is designed for a specific camera model, as controls and dimensions differ. Generic housings exist but offer limited functionality.

How do I prevent leakage in a housing?

Always inspect and lubricate O-rings before each dive. Ensure no sand or hair is on seals. Test the housing without camera in shallow water before use.
