Hi, Welcome to undrewater photography, you will not regret it, its fantastic. I have been hiring camera`s for the past year, and now i have my own, a canon A640 with a DC-8 housing. Please take the housing down with you to test it,first, as i had a leak on my first dive,not knowing how much silicone grease to put on the "o" ring and luckly having the small silicone packets inside it i saved my camera.Enjoy......
