Photographers typically have two options when shooting underwater: double the size of their D-SLR with an expensive submersible housing or opt for a waterproof point-and-shoot with the image quality of, well, a point-and-shoot. Mirrorless interchangeable-lens cameras, such as the Nikon 1 AW1, produce D-SLR–quality images minus the delicate moving parts of D-SLRs themselves. The compact internals allow engineers to ruggedize and seal the camera without adding much bulk.
When a lens zooms, small crevices between the stacked components open. The entire AW1 lens is enclosed in a sealed barrel. As the camera zooms—up to 27.5 millimeters—all the parts remain protected.
The lens mount on the AW1 is raised about six millimeters above the camera body. Lenses slip over it and into a groove in the housing. A greased rubber O-ring fills in any gap between the two pieces.
The AW1’s pop-up flash can illuminate up to 16 feet of seawater ahead of the diver. The bulb is attached to a sealed two-joint hinge. Power travels from the camera body through insulated wires.
To ensure that the doors to the SD card and battery compartments won’t open underwater, designers added two-button locking mechanisms and lined each door with rubber gaskets.
The housing is a composite of stainless steel and polycarbonate, which protects the camera—and its three-inch LCD—if it drops. Every seam is backed with rubber, too.
