Canon WP-DC34 Waterproof Housing for PowerShot G11 and G12 Digital Cameras Reviews:
Worked exactly as hoped
Bought this housing to take my G12 snorkeling in Hawaii, and it worked great. Not too large, and all functions are accessible. I found the strap provided was useful for carrying when on land, but it was annoying in the water. It's not long enough or convenient to have around my neck when snorkeling, and too long and floating in the way when not around my neck. Preferred to use the short wrist strap from the camera that had a sliding lock, which I transferred to the housing. Also needed all 4 of the accessory weights to get neutral buoyancy in salt water. Always had a silica gel pack in the housing and had no condensation issues. Only used to 15 foot depth.
I am very happy with this housing! First, it has cool colors. Then my G12 fits incredible well and all the function buttons all work very well. I really like the way the lens is set back from the outer glass so you can get a view above and below the water. I have only shot fish in a pond so far but this camera housing will open up other opportunities for photo in and around the water. Oh and the price is right.

Worked fine, the buttons were a little awkward under water to use.
