In the search for some alternative solutions I have been watching evolution of Canon PowerShot G series cameras. Canon offers waterproof cases for them.
Some posts from winter paddling:
Good news: Your camera is not broken! Bad News: It is normal, unfortunately. These little cameras are very good in recording noise from lens mechanism/motor when zooming or autofocusing.

I discovered the South Platte River for paddling almost 8 years ago in January 2001. I believe it was the first river I paddled in northern Colorado and, for sure, my first winter paddling here. Here is some old writing on these day trips with my CLC Patuxent 10.5 kayak. It was originally posted on Mountain Wayfarer site. At that time, I was shooting slides with Canon EOS 2AE SLR camera.
I was launching my kayak at Mitani-Tokuyasu State Wilderness Area just below the mouth of the Cache la Poudre River. This place is less suitable for paddling now days. It is open only during a hunting season and closes by the end of February. A parking space is limited to 4 cars only. See my GPS/photo river guide for other access points.
