The Canon WP-DC38 is an underwater housing designed specifically for the Canon PowerShot S95. The case is depth rated to 40m, allowing the S95 to be used whilst diving or snorkeling and includes a removable diffuser for use with a built in flash. The WP-DC38 is also incredibly tough, offering the PowerShot S95 additional protection on dry land. Prevent the case from floating while taking pictures underwater with the Canon WW-DC1 Compensation weights (sold separately).
What can I say? It's much cheaper than the 3rd party cases for an S95. Strap on an inon LD adapter and you can mount amazing Inon lenses. What more do you want? The Ikelite's and others have M67 lenses, which are heavy ... this is great.
