Underwater camera housing

Underwater camera housings enable photographers and filmmakers to capture images at depths ranging from a few meters to hundreds, protecting sensitive equipment from pressure and water.

About this subject

Underwater camera housings are sealed enclosures designed to protect cameras and camcorders during diving, allowing photographers and filmmakers to operate camera controls through external buttons, levers, and dials. The first such housings appeared in the 1950s, often handcrafted from metal and acrylic, but serial production gained momentum in the 1980s with the rise of recreational scuba diving. Modern housings are typically made of anodized aluminum or polycarbonate, with silicone or rubber O-rings for sealing. Depth ratings range from 40 meters for amateur models to over 100 meters for professional units. One key engineering challenge is the lens port system, which must allow lens changes underwater without breaking the seal. Leading brands include Nauticam, Ikelite, AquaTech, and Seacam, offering solutions for DSLR, mirrorless, and even smartphone cameras. Underwater housings are vital not only for artistic reef and marine life photography but also for scientific research, underwater structure inspection, and cinematic productions such as the BBC's 'Blue Planet' series.

Frequently Asked Questions

What is the maximum depth an underwater camera housing can withstand?

It depends on the model: recreational housings typically handle 40 to 60 meters, while professional or technical units can reach 100 meters or more, depending on materials and design.

What materials are used to make underwater camera housings?

The most common are anodized aluminum (lightweight and corrosion-resistant) and polycarbonate (transparent and more affordable). Both use silicone or rubber O-rings for sealing.

Can any camera be used in an underwater housing?

No. Specific models exist for each camera type. Brands like Nauticam and Ikelite manufacture housings designed for DSLRs, mirrorless, compact, and even smartphone cameras, ensuring proper alignment of controls and ports.
