Some cameras offer specialty equipment as well, such as underwater housing.

Both cameras are self-propelling underwater housings for a set of three Canon 5D cameras using wide-angle lenses.

Rolleimarin: underwater housing.

And now a Hasselblad can go under water; an underwater housing, the H38, was introduced in April.

Canon has also introduced a $240 underwater housing, the WP-DC40, which is compatible with either camera.

The E-620 also has its own underwater housing, PT-E06, submersible down to 40 meters.

Most modern underwater housing are pressure resistant to about one hundred feet, the practical safe depth of sport-diving.

Occasionally housings might be advertised as "water housings" rather than underwater housings.

For a reusable camera complete with an underwater housing, the price is very reasonable.
