I am in the process of selecting a new camera. I had two olympus cameras in the past and both flooded. I also have a very cheap canon camera and I never had a problem with it. I want to know what do you think, which brand do you prefer and why, and which housings do you prefer and why. I am looking into the A720 from canon or SP-550UZ from olympus for my next camera. Any advise/suggestions are greatly appreciated.
