Camera Questions for Christian

Christian, You helped me a little while back on deciding on a camera. I was wondering if you could help me again. I still havent decided on which camera to get. But i have a new concern. Most of the waves that will be good enough to take pictures of will occur in water anywhere from 70-30 degrees. Can a camera withstand 30 degree water temps? I am right now looking at the C-5050 from olympus with a housing they provide. Thanks for any help you can give me. Tom
