As a holiday diver I have been a long time on the search for an acceptable solution for digital underwater photography. One can not expect miracles in the amateur, it became clear to me after some research. The price / performance ratio in underwater housing WP-DC500 Canon's true - a solid finish, all camera operations can also be used underwater. The scope of supply nor a shoulder strap and a carrying strap, a tube of anti-fog paste and a tube of powder for care of the O-ring sealing of the housing. I would recommend this product highly.
